where  is the rgb color to match in hex (ex: 0x000000 for black),  is a tolerance on the color-match (ex: 0.3), and  (ex: 0.2) controls whether the opacity is on-off or how gradual it is. (See the documentation for more).

Create a Video with a Histogram Overlay

Joining Image Files

Without audio
ffmpeg \
-loop 1 -framerate 24 -t 10 -i image1.jpg \
-i video.mp4 \
-loop 1 -framerate 24 -t 10 -i image2.jpg \
-loop 1 -framerate 24 -t 10 -i image3.jpg \
-filter_complex "[0][1][2][3]concat=n=4:v=1:a=0" out.mp4
Match -framerate with frame rate from video.mp4.
With audio
If there is audio in video.mp4 you'll need to provide audio for the images as well for it to be able to concatenate. Example of generating silence:

ffmpeg \
-loop 1 -framerate 24 -t 10 -i image1.jpg \
-i video.mp4 \
-loop 1 -framerate 24 -t 10 -i image2.jpg \
-loop 1 -framerate 24 -t 10 -i image3.jpg \
-f lavfi -t 0.1 -i anullsrc=channel_layout=stereo:sample_rate=44100 \
-filter_complex "[0:v][4:a][1:v][1:a][2:v][4:a][3:v][4:a]concat=n=4:v=1:a=1" out.mp4

Joining Video Files

Mp4 files may not be concated directly because the contain headers.
EXAMPLE: ffmpeg -f concat -i mylist.txt -c copy video_draft.avi

OR 
 cat mylist.txt
file 'banjo1.mp4'
file 'banjo2.mp4'

$ ffmpeg -f concat -i mylist.txt -c copy banjo-player.mp4

----------------- Good for mixed codecs --------------------------

I Use This Screen Recorder

  USED DECEMBER 8, 2018:
  Worked fine

I have created a script to auto-capture a full screen with sound:
it will capture the video and save it the current date in what ever directory it is run:

------------------- scrCAP -----------------------
#!/bin/bash
ffmpeg -y  -f alsa -ac 2 -i hw:1,0 -strict -2 -f x11grab -framerate 30 -video_size 1360x766 -i :0.0 \

Ffmpeg may be used with no options
The i- following ffmpeg proceeds the file name. The simple command below uses same size and the frame rate defaults to 25 ( -framerate 25 ).


ffmpeg -i infile.avi youroutput.mp4

If you wish to keep the frame sizes and frame rate intact use the -strict option. it results in a high quality video if possible.

ffmpeg -i input.avi -strict -2 output.mp4

ffmpeg -i input.mkv -codec copy output.mp4


 
Good Screen Capture - NO errors

Adjust Contrast

contrast may range from -2 to plus 2.
It may be run on the output file to REALLY increase the contrast.  
ffmpeg -i postsized.mp4 -filter_complex "eq=contrast=2:brightness=0:saturation=1:gamma=1:gamma_r=1:gamma_g=1:gamma_b=1:gamma_weight=1" contrast.mp4
Set brightness, contrast, saturation and approximate gamma adjustment.
The filter options:
contrast float value in range -2.0 to 2.0. The default value is "1".
brightness
Set the brightness expression. The value must be a float value in range -1.0 to 1.0. The default value is "0".
saturation float in range 0.0 to 3.0. The default value is "1".
gamma float in range 0.1 to 10.0. The default value is "1".
gamma_r float in range 0.1 to 10.0. The default value is "1".
gamma_g float in range 0.1 to 10.0. The default value is "1".
gamma_b float in range 0.1 to 10.0. The default value is "1".
gamma_weight float in range 0.0 to 1.0. A value of 0.0 turns the gamma correction all the way down while 1.0 leaves it at its full strength. Default is "1".reduce the effect of a high gamma value on bright image areas it will prevent them from getting overamplified and just plain white.

Two Videos Side by Side

This essentially doubles the size of input1.mp4 by padding the right side with black the same size as the original video, and then places input2.mp4 over the top of that black area with the overlay filter.

Another File information command

The command below command is no designed to be a file information command, however it works as one. As you see it provides some erroneous information and concludes with an error "At least one output file must be specified". Ffprobe is the desired means of acquiring information.

EXPERIMENT
To show streaming video in a port.
ffmpeg -i /dev/video0 -listen 1 -f matroska -c:v libx264 -preset fast -tune zerolatency http://:8080 ffplay http://localhost:8080/ 

See the scale and unsharp filters in ffmpeg:

ffmpeg -i input -filter:v "scale=1280:-1,unsharp=5:5:1.0:5:5:0.0" output

The -1 in the scale filter tells ffmpeg to automatically choose the correct height to preserve aspect ratio. You can change the scaler with the -sws_flags option, such as -sws_flags lanczos. For upsampling lanczos is worth trying. Default is bicubic. See the full list at ffmpeg -h full.

profile your inputs files. list profiles  -       melt -query profiles 
 melt -query "profile=atsc_720p_25".

This example is using a profile that sets a frame rate of 25, so 25 frames equals 1 second.

mix sets the duration of the fade. The value is in frames.
mixer sets the type of mix.


fade and blend two videos


First video fades to alpha in the 4th second (st=4) during 1 second (d=1),
fade in the second one at 0 second (st=0) during 1 second (d=1) 
and moves it's display time forward to 4 sec (+4/TB). 
Then we just cut 9 second of black color,
scale it to output video size and overlay the stuff.

ffmpeg -i output.mp4 -i output2.mp4 -f lavfi -i color=black -filter_complex "[0:v]format=pix_fmts=yuva420p,fade=t=out:st=4:d=1:alpha=1,setpts=PTS-STARTPTS[va0]; [1:v]format=pix_fmts=yuva420p,fade=t=in:st=0:d=1:alpha=1,setpts=PTS-STARTPTS+4/TB[va1]; [2:v]scale=1280x720,trim=duration=9[over]; [over][va0]overlay[over1]; [over1][va1]overlay=format=yuv420[outv]" -vcodec libx264 -map [outv] out.mp4


to Maintain aspect of if a square video is placed in a 1280x720 container


ffmpeg -i output.mp4 -i output2.mp4 -f lavfi -i color=black -filter_complex "[0:v]format=pix_fmts=yuva420p,fade=t=out:st=4:d=1:alpha=1,setpts=PTS-STARTPTS[va0]; [1:v]format=pix_fmts=yuva420p,fade=t=in:st=0:d=1:alpha=1,setpts=PTS-STARTPTS+4/TB[va1]; [2:v]scale=1280:-1,trim=duration=9[over]; [over][va0]overlay[over1]; [over1][va1]overlay=format=yuv420[outv]" -vcodec libx264 -map [outv] out.mp4



ffmpeg -i voko1.mp4  -i fade.png -filter_complex " [0:v][1:v] overlay=0:0:enable='between(t,5,10)',fade=t=in:st=5:d=1, fade=t=out:st=10:d=1  '" -c:v libx264 -crf 23 -t 59 fadeout.mp4

With "overlay[...],fade[...],fade[...]", you're appying the fading to the
whole video and not just the overlay. It's a filter chain, you see, and
the fade filters are chained behind the overlay.

You will want to do something like adding "-loop 1" before the overlay
image, and then using a filter like this:

 ffmpeg -i voko1.mp4  -i fade.png -filter_complex "[1:v]fade=t=in:st=5:d=1,fade=t=out:st=10:d=1[over];[0:v][over]overlay=0:0" -c:v libx264 -crf 23 -t 59 fadeoutput.mp4

This works Fade Sound and video in and Out
Tried and it works fine
ffmpeg -i fadevid-notsound.mp4 -vf 'fade=in:0:240,fade=out:1600:170' -af 'afade=in:st=0:d=10,afade=out:st=55:d=4' -c:v libx264 -crf 22 -preset veryfast fadeInOut4.mp4

Get number of frames in a video
ffmpeg -i fadevid-notsound.mp4 -vcodec copy -f rawvideo -y /dev/null 2>&1 | tr ^M '\n' | awk '/^frame=/ {print $2}'|tail -n 1

returns a number 1770





WORKS FINE
ffmpeg -i edit.mkv -vf "scale='min(1000,iw)':min'(1000,ih)':force_original_aspect_ratio=decrease,pad=1000:1000:100:218:color=blue" edit7.mkv

Some Image Stuff 
Batch convert jpeg to png:

mogrify -format png *.jpg


mogrify -resize 277x277 *.png



This will convert image to grayscale and remove all black ( #fff ) or white ( #000 ).

 

convert 0001.png -alpha copy -fx '#fff' 0101result.png


( you can make some fantastic paintbrushes. with this )

convert 0001.png -alpha copy -fx '#000' 0101result000.png


convert test.png -transparent white transparent.png 

( removes all the black element of a png - similar to using alpha color in graphics programs )

General Rules

Order is incredibly important;

Error checking on command line parsing is weak;

Please refer to the plugins documentation for details on services available;

The MLT framework, from which melt has inherited its naming convention, is very MLT-centric. Producers produce MLT frame objects and consumers consume MLT frame objects. The distinction is important - a DV producer does not produce DV, it produces MLT frames from a DV source, and similarly a DV consumer does not consume DV, it consumes MLT frames and produces DV frames.

Terminology

‘Producers’ typically refer to files but may also indicate devices (such as dv1394 input or video4linux). Hence, the more generic term is used [the more generic usage is out of scope for now…].

‘Filters’ are frame modifiers - they always guarantee that for every frame they receive, they output precisely one frame. Never more, never less, ever. Nothing says that a filter cannot generate frames though.

‘Transitions’ collect frames from two tracks (a and b) and output 1 modified frame on their ‘a track’, and 1 unmodified frame on their ‘b track’. Never more, never less, ever.

‘Consumers’ collect frames from a producer, do something with them and destroy them.

Collectively, these are known as ‘services’. All services have ‘properties’ associated to them. These are typically defaulted or evaluated and may be overriden on a case by case basis. All services except consumers obey in and out properties.

Consumers have no say in the flow of frames (though they may give the illusion that they do). They get frames from a connected producer, use them, destroy them and get more.

Basics
To play a file with the default SDL PAL consumer, usage is: melt file

Note that ‘file’ can be anything that melt has a known ‘producer’ mapping for (so this can be anything from .dv to .txt). You can also specify the producer directly, for example: melt avformat:file.mpeg would force the direct use of avformat for loading the file.

Properties

Properties can be assigned to the producer by adding additional name=value pairs after the producer: melt file in=50 out=100 something="something else"

Note that while some properties have meaning to all producers (for example: in, out and length are guaranteed to be valid for all, though typically, length is determined automatically), the validity of others are dependent on the producer - however, properties will always be assigned and silently ignored if they won’t be used.

Multiple Files

Multiple files of different types can be used: melt a.dv b.mpg c.png

Properties can be assigned to each file: melt a.dv in=50 out=100 b.mpg out=500 c.png out=500

MLT will take care of normalizing the output of a producer to ensure that the consumer gets what it needs. So, in the case above, the mlt framework will ensure that images are rescaled and audio resampled to meet the requirements of your configuration (which, by default, will be PAL).

Consumers

Consumers are the components that process the generated frames. If no consumer is specified, then the “sdl” consumer is used, which displays the resulting video in a simple playback window.

$ melt -query consumers
   ---
   consumers:
     - blipflash
     - jack
     - qglsl
     - multi
     - null
     - gtk2_preview
     - cbrts
     - xgl
     - decklink
     - sdl
     - sdl_audio
     - sdl_preview
     - sdl_still
     - avformat
     - rtaudio
     - sdi
     - xml
   ...
To output a file from the melt command, choose a generic encoder like “avformat”. The following flags create an encoded video file for the results of a melt command. -consumer avformat:output.avi acodec=libmp3lame vcodec=libx264

Filters

Filters are frame modifiers - they can change the contents of the audio or the images associated to a frame. melt a.dv -filter greyscale

As with producers, properties may be specified on filters too.

Again, in and out properties are common to all, so to apply a filter to a range of frames, you would use something like: melt a.dv -filter greyscale in=0 out=50

Filters have their own set of rules about properties and will silently ignore properties that do not apply.

Groups

The -group switch is provided to force default properties on the following ‘services’. For example: melt -group in=0 out=49 clip*

would play the first 50 frames of all clips that match the wild card pattern.

Note that the last -group settings also apply to the following filters, transitions and consumers, so: melt -group in=0 out=49 clip* -filter greyscale

is probably not what you want (ie: the greyscale filter would only be applied to the first 50 frames).

To shed the group properties, you can use any empty group: melt -group in=0 out=49 clip* -group -filter greyscale

Attached Filters

As described above, the -filter switch applies filters to an entire track. To localise filters to a specific clip on a track, you have to know information about the lengths of the clip and all clips leading up to it. In practise, this is horrifically impractical, especially at a command line level (and not even that practical from a programing point of view…).

The -attach family of switches simplify things enormously. By default, -attach will attach a filter to the last service created, so: melt clip1.dv clip2.dv -attach greyscale clip3.dv would only apply the filter to clip2.dv. You can further narrow down the area of the effect by specifying in/out points on the attached filter.

This might seem simple so far, but there is a catch… consider the following: melt clip1.dv -attach watermark:+hello.txt -attach invert

The second attached filter is actually attached to the watermark. You might think, yay, nice (and it is :-)), but, it might not be what you want. For example you might want to attach both to clip1.dv. To do that, you can use: melt clip1.dv -attach-cut watermark:+hello.txt -attach-cut invert

As you shall see below, there are still another couple of gotchas associated to -attach, and even another variant :-).

Mixes

The -mix switch provides the simplest means to introduce transitions between adjacent clips.

For example: melt clip1.dv clip2.dv -mix 25 -mixer luma -mixer mix:-1

would provide both an audio and video transition between clip1 and clip2.

This functionality supercedes the enforced use of the -track and -transition switches from earlier versions of melt and makes life a lot easier :-).

These can be used in combination, so you can for example do a fade from black and to black using the following: melt colour:black out=24 clip1.dv -mix 25 -mixer luma colour:black out=24 -mix 25 -mixer luma

While this may not be immediately obvious, consider what’s happening as the command line is being parsed from left to right:

  Input:                  Track
  ----------------------- -----------------------------------------------------
  colour:black out=24     [black]
  clip1.dv                [black][clip1.dv]
  -mix 25                 [black+clip1.dv][clip1.dv]
  -mixer luma             [luma:black+clip1.dv][clip1.dv]
  colour:black out=24     [luma:black+clip1.dv][clip1.dv][black]
  -mix 25                 [luma:black+clip1.dv][clip1.dv][clip1.dv+black]
  -mixer luma             [luma:black+clip1.dv][clip1.dv][luma:clip1.dv+black]
Obviously, the clip1.dv instances refer to different parts of the clip, but hopefully that will demonstrate what happens as we construct the track.

You will find more details on the mix in Documentation > Framework.

Mix and Attach

As noted, -attach normally applies to the last created service - so, you can attach a filter to the transition region using: melt clip1.dv clip2.dv -mix 25 -mixer luma -attach watermark:+Transition.txt

Again, nice, but take care - if you want the attached filter to be associated to the region following the transition, use -attach-cut instead.

Introducing Tracks and Blanks
So far, all of the examples have shown the definition of a single playlist, or more accurately, track. When multiple tracks exist, the consumer will receive a frame from the ‘highest numbered’ track that is generating a non-blank frame.

It is best to visualise a track arrangement, so we’ll start with an example: melt a.dv -track b.dv in=0 out=49

This can be visualised as follows:

+------------------+
|a                 |
+-------+----------+
|b      |
+-------+
Playout will show the first 50 frames of b and the 51st frame shown will be the 51st frame of a.

This rule also applies to audio only producers on the second track, for example, the following would show the video from the a track, but the audio would come from the second track: melt a.dv -track b.mp3 in=0 out=49

To have the 51st frame be the first frame of b, we can use the -blank switch: melt a.dv out=49 -track -blank 49 b.dv

Which we can visualise as:

+-------+
|a      |
+-------+-------------------+
        |b                  |
        +-------------------+
Now playout will continue as though a and b clips are on the same track (which on its own, is about as useful as reversing the process of slicing bread).

Transitions

Where tracks become useful is in the placing of transitions. Here we need tracks to overlap, so a useful multitrack definition could be given as:

melt a.dv out=49 \
-track \
-blank 24 b.dv \
-transition luma in=25 out=49 a_track=0 b_track=1
Now we’re cooking - our visualization would be something like:

+-------+
|a      |
+---+---+--------------+
    |b                 |
    +------------------+
Playout will now show the first 25 frames of a and then a fade transition for 25 frames between a and b, and will finally playout the remainder of b.

Reversing a Transition

When we visualise a track definition, we also see situations like:

+-------+              +----------+
|a1     |              |a2        |
+---+---+--------------+----+-----+
    |b                      |
    +-----------------------+
We have two transitions, a1 to b and b to a2. In this scenario, we define a command line as follows:

melt a.dv out=49 -blank 49 a2.dv \
-track \
-blank 24 b.dv out=99 \
-transition luma in=25 out=49 a_track=0 b_track=1 \
-transition luma in=100 out=124 reverse=1 a_track=0 b_track=1
Serialization
Melt has a built in serialization mechanism - you can build up your command, test it via any consumer and then add a -serialise file.melt switch to save it. The saved file can be subsequently used as a clip by melt or other MLT applications. Take care though - paths to files are saved as provided on the command line….

A more expressive serialization can be obtained with the xml consumer - this will provide an xml document which can be used freely in melt and other MLT applications.

See MLT XML for more information.

Missing Features
Some filters/transitions should be applied on the output frame regardless of which track it comes from - for example, you might have a 3rd text track or a watermark which you want composited on every frame, and of course, there’s the obscure filter….

Melt only supports this in two invocations - as a simple example:

melt a.dv -track -blank 100 b.dv -consumer xml:basic.mlt
melt basic.mlt -filter watermark:watermark.png

contrast: pressing 1 and 2 allows you to decrease / increase the contrast.
brightness: pressing 3 and 4 will adjust the brightness
hue: pressing 5 and 6 will adjust the hue
saturation:  pressing 7 and 8 will adjust the image saturation
always on top: pressing T will keep the video window always on top of the other windows.



The typical syntax of the FFmpeg command is:

ffmpeg [global_options] {[input_file_options] -i input_url} ...
 {[output_file_options] output_url} ...


To display your media details:
$ ffmpeg -i video.mp4

If you don’t want to see the FFmpeg banner and other details
use -hide_banner flag like below.
$ ffmpeg -i video.mp4 -hide_banner

Convert mp4 file to avi file, run:
$ ffmpeg -i video.mp4 video.avi

Convert media files to any format of your choice.
$ ffmpeg -i video.flv video.mpeg

If you want to preserve the quality of your source video file, use ‘-qscale 0’ parameter:
$ ffmpeg -i input.webm -qscale 0 output.mp4

To check list of supported formats by FFmpeg, run:
$ ffmpeg -formats

3. Converting video files to audio files
Convert input.mp4 video file to output.mp3 audio file.
$ ffmpeg -i input.mp4 -vn -ab 320 output.mp3

Also, you can use various audio transcoding options to the output file as shown below.
$ ffmpeg -i input.mp4 -vn -ar 44100 -ac 2 -ab 320 -f mp3 output.mp3

    -vn – Indicates that we have disabled video recording in the output file.
    -ar – Set the audio frequency of the output file. The common values used are  22050, 44100, 48000 Hz.
    -ac – Set the number of audio channels.
    -ab – Indicates the audio bitrate.
    -f – Output file format. In our case, it’s mp3 format.

4. Change resolution of video files
$ ffmpeg -i input.mp4 -filter:v scale=1280:720 -c:a copy output.mp4

Set the resolution of the given video file to 1280×720.
$ ffmpeg -i input.mp4 -s 1280x720 -c:a copy output.mp4

Convert the above file to 640×480 size, run:
$ ffmpeg -i input.mp4 -filter:v scale=640:480 -c:a copy output.mp4
$ ffmpeg -i input.mp4 -s 640x480 -c:a copy output.mp4

5. Compressing video files

It is always better to reduce the media files size to lower size to save the harddisk’s space.

The following command will compress and reduce the output file’s size.
$ ffmpeg -i input.mp4 -vf scale=1280:-1 -c:v libx264 -preset veryslow -crf 24 output.mp4
You will lose the quality if you try to reduce the video file size. You can lower that crf value to 23 or lower if 24 is too much.

You can also transcode the audio down a bit and make it stereo to reduce the size by including the following options.
$ ffmpeg -i input.mp4 -vf scale=1280:-1 -c:v libx264 -preset veryslow -crf 24 -ac 2 -c:a aac -strict -2 -b:a 128k output.mp4

Recommended Download – Free Guide: “PLEX, a Manual: Your Media, With Style”

6. Compress audio files using -ab flag in order to save some disk space.
An audio file of 320 kbps bitrate. You want to compress it by changing the bitrate to any lower value like below.
$ ffmpeg -i input.mp3 -ab 128 output.mp3

Various available audio bitrates are:

    96kbps
    112kbps
    128kbps
    160kbps
    192kbps
    256kbps
    320kbps

7. If you don’t want audio in a video file, remove it with -an flag. The ‘an’ indicates no audio recording.
$ ffmpeg -i input.mp4 -an output.mp4

Here, ‘an’ indicates no audio recording.

The above command will undo all audio related flags, because we don’t audio from the input.mp4.

8. Removing video stream from a media file,remove it with -vn flag. 
$ ffmpeg -i input.mp4 -vn output.mp3

You may change the output file’s bitrate using ‘-ab’ flag as shown in the following example.
$ ffmpeg -i input.mp4 -vn -ab 320 output.mp3

9. Extracting images from the video 
$ ffmpeg -i input.mp4 -r 1 -f image2 image-%2d.png

    -r – Set the frame rate. I.e the number of frames to be extracted into images per second. The default value is 25.
    -f – Indicates the output format i.e image format in our case.
    image-%2d.png – Indicates how we want to name the extracted images. In this case, the names should start like image-01.png, image-02.png, image-03.png and so on. If you use %3d, then the name of images will start like image-001.png, image-002.png and so on.

10. Cropping videos
$ ffmpeg -i input.mp4 -croptop 100 -cropbottom 100 -cropleft 300 -cropright 300 output.mp4
$ ffmpeg -i thefishcut01.mkv -ss 2 -filter:v "crop=380:380:300:215" Fish-cropped2.mp4
Note that cropping videos will affect the quality. Do not do this unless it is necessary.

11. Convert a specific portion of a video
first 50 seconds of given video.mp4 file to video.avi format.
$ ffmpeg -i input.mp4  -t 50 output.avi
The time here is seconds. It is possible to specify the time in hh.mm.ss format.

12. Set the aspect ratio to video
You can set the aspect ration to a video file using -aspect flag like below.
$ ffmpeg -i input.mp4 -aspect 16:9 output.mp4

Common aspect ratios are:
    16:9
    4:3
    16:10
    5:4
    2:21:1
    2:35:1
    2:39:1

13. Adding poster image to audio files
$ ffmpeg -loop 1 -i inputimage.jpg -i inputaudio.mp3 -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest output.mp4

14. Trim a media file using start and stop times
$ ffmpeg -i input.mp4 -ss 00:00:50 -codec copy -t 50 output.mp4
    -s – Indicates the starting time of the video clip. In our example, starting time is the 50th second.
    -t – Indicates the total time duration.

$ ffmpeg -i audio.mp3 -ss 00:01:54 -to 00:06:53 -c copy output.mp3

15. Split video files into multiple parts
$ ffmpeg -i input.mp4 -t 00:00:30 -c copy part1.mp4 -ss 00:00:30 -codec copy part2.mp4
   -t 00:00:30 indicates a part that is created from the start of the video to the 30th second of video. -ss 00:00:30 shows the starting time stamp for the video. It means that the 2nd part will start from the 30th second and will continue up to the end of the original video file.

16. Joining multiple video parts into one
Create join.txt file that contains the exact paths of the files that you want to join. 
All files should be same format (same codec). 
The path name of all files should be mentioned one by one like below.

/home/sk/myvideos/part1.mp4
/home/sk/myvideos/part2.mp4
/home/sk/myvideos/part3.mp4
/home/sk/myvideos/part4.mp4

Join all files using command:
$ ffmpeg -f concat -i join.txt -c copy output.mp4
The above command will join part1.mp4, part2.mp4, part3.mp4, and part4,mp4 files into a single file called “output.mp4”.

----------------- Good for mixed codecs --------------------------
ffmpeg -i intro.mkv -i part2.mkv \
-filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa]" \
-map "[outv]" -map "[outa]" -t 30 bothoutput.mkv
------------------------------------------------------------------

17. Add subtitles to a video file
$ fmpeg -i input.mp4 -i subtitle.srt -map 0 -map 1 -c copy -c:v libx264 -crf 23 -preset veryfast output.mp4

18. Preview or test video or audio files
$ ffplay video.mp4

$ ffplay audio.mp3

19. Increase/decrease video playback speed
$ ffmpeg -i inputvideo.mp4 -vf "setpts=0.5*PTS" outputvideo.mp4
To decrease playback speed, run:
$ ffmpeg -i inputvideo.mp4 -vf "setpts=4.0*PTS" outputvideo.mp4

$ man ffmpeg
-----------------------

ffmpeg.exe -i "movie.mp4" -itsoffset 3.84 -i "movie.mp4" -map 1:v -map 0:a -c copy "movie-video-delayed.mp4"

If you need to delay audio by 3.84 seconds, use a command like this:

ffmpeg.exe -i "movie.mp4" -itsoffset 3.84 -i "movie.mp4" -map 0:v -map 1:a -c copy "movie-audio-delayed.mp4"

Make sure, that your ffmpeg build is not too old, newer than 2012 will suffice.

Explanation

-itsoffset 3.84 -i "movie.mp4"

Offsets timestamps of all streams by 3.84 seconds in the input file that follows the option (movie.mp4).

-map 1:v -map 0:a

Takes video stream from the second (delayed) input and audio stream from the first input - both inputs may of course be the same file.

A more verbose explanation can be found here:
http://alien.slackbook.org/blog/fixing-audio-sync-with-ffmpeg/

-------------
ffmpeg -i input.mp4 -i logo.png -filter_complex \
"overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2" \
-codec:a copy output.mp4

or with the shortened overlay options:

overlay=(W-w)/2:(H-h)/2

Top left

This is the easy one because the default, if you provide no options to overlay, is to place the image in the top left.

This example adds 5 pixels of padding so the image is not touching the edges:

overlay=5:5

Top right

With 5 pixels of padding:

overlay=main_w-overlay_w-5:5

or with the shortened options:

overlay=W-w-5:5

Bottom right

With 5 pixels of padding:

overlay=main_w-overlay_w-5:main_h-overlay_h-5

or with the shortened options:

overlay=W-w-5:H-h-5

Bottom left

With 5 pixels of padding:

overlay=5:main_h-overlay_h

or with the shortened options:

overlay=5:H-h-5

Notes

    The audio is simply stream copied (remuxed) in this example with -codec:a copy instead of being re-encoded. You may have to re-encode depending on your output container format.

    See the documentation on the overlay video filter for more information and examples.

    See the FFmpeg H.264 Video Encoding Guide for more information on getting a good quality output.

    If your image being overlaid is RGB colorspace (such as most PNG images) you may see a visual improvement if you add format=rbg to your overlay. Note that if you do this and if you're outputting H.264, then you will have to add format=yuv420p (this is another filer–it is different that the similarly named option in the overlay filter). So it may look like this:

    overlay=5:H-h-5:format=rgb,format=yuv420p

-----------------------
The basic method to join videos without re-encoding is to use the concat demuxer. This device requires that the files being joined share certain properties, like codec, framerate, video dimensions, timebase..etc

First step is to create the blank segment, which may be used both at the head and tail.

ffmpeg -i fullvideo.mp4 -vf trim=0:3,geq=0:128:128 -af atrim=0:3,volume=0 -video_track_timescale 600 3sec.mp4

Have to do one bookkeeping step for the full video. If not done, the combined video will likely run at the wrong speed.

ffmpeg -i fullvideo.mp4 -c copy -video_track_timescale 600 full600.mp4

Next, create a text file.

file 3sec.mp4
file full600.mp4
file 3sec.mp4

Then run

ffmpeg -f concat -i list.txt -c copy merged.mp4
---------------------------------------
For changing the background, you should look into the colorkey filter. From the docs, here's an example to "make every green pixel in the input image transparent":

ffmpeg -i input.png -vf colorkey=green out.png








-i input.mp4  -loop 1 -i 34232944.png -filter_complex " [0:v][1:v]
overlay=0:0:enable='between(t,5,10)',fade=t=in:st=5:d=1,
fade=t=out:st=10:d=1  '" -c:v libx264 -crf 23 output001.mp4


ffmpeg -i good.mp4 -loop 1 image0.png -filter_complex "[1:v]fade=t=in:st=34:d=1,fade=t=out:st=6:d=1[over];[0:v][over]overlay=0:0"  -c:v libx264 -crf 23 -c:a copy output001.mp4
