Useful FFmpeg commands

The use of video in digital life is increasing exponentially day by day. I prepared a document explaining how you can easily find answers to video solutions/problems that you will need in daily life with FFmpeg library. I show you which commands to run for video solutions you will need with about 20 different scenarios in the file. You can forward your questions/questions about the document from the Issues section.

Download FFmpeg to your computer for Windows => https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-latest-win64-gpl-shared-4.4.zip for Mac Os => https://evermeet After downloading from .cx/ffmpeg/ffmpeg-105012-gbb813ccb45.zip addresses, you can run ffmpeg as arguments by entering bin folder via terminal.

1. Convert any video format to other format.

ffmpeg -i source.avi output.mp4

ffmpeg -i source.mov output.mp4

2. Increasing/decreasing the framerate of the video. (Twitter and some platforms require 30FPS video)

ffmpeg -i source.mp4 -framerate 30 output30fps.mp4

3. Adding audio to video.

It will be as long as the video or audio, whichever is shorter.

ffmpeg -i source.mp4 -i sound.mp3 -vcodec copy -map 0:v -map 1:a -map 1:a -shortest output.mp4

4. Cutting the first three seconds of the video.

ffmpeg -i source.mp4 -t 3 output3seconds.mp4

or

ffmpeg -i source.mp4 -t 00:00:03 output3seconds.mp4

5. Cut a specific range of video.

Getting next 3 seconds starting from 3 seconds

ffmpeg ffmpeg -i source.mp4 -ss 3 -t 3 source3seconds.mp4

6. Cut video from a specific second to the end of the video

ffmpeg ffmpeg -i source.mp4 -ss 3 output3seconds.mp4

ffmpeg ffmpeg -i source.mp4 -ss 00:00:03 output3seconds.mp4

7. Convert video to animated gif.

ffmpeg -i source.mp4 -vf "fps=10,scale=320:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0 output.gif

8. Converting part of video to animated gif.

ffmpeg -i source.mp4 -ss 1 -t2 -vf "fps=10,scale=320:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0 tar.gif

9. Concat two videos (without audio).

ffmpeg -i source1.mp4 -i source2.mp4 -y -filter_complex "[0:v][1:v] concat=n=2:v=1:[v]" -map "[v]" output.mp4

10. Concat two videos back-to-back (with audio).

ffmpeg -i source1.mp4 -i source2.mp4 -y -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0] concat=n=2:v=1:a=1 [v] [a]" -map "[a]" -map "[v]" output.mp4

11. Adding a watermark to the middle of the screen.

ffmpeg.exe -i source.mp4 -i logo.png -filter_complex "overlay = (main_w - overlay_w)/2:(main_h - overlay_h) / 2" watermark.mp4

12. Adding a watermark to a specific point of the screen.

ffmpeg -i source.mp4 -i logo.png -filter_complex "overlay = (main_w - overlay_w)/2:(main_h - overlay_h) / 2" watermark.mp4

13. Extracting all the frames in the video as an image

ffmpeg -i source.mp4 "%04d.png"

14. Take a screenshot of a specific frame in the video.

ffmpeg -i wm.mp4 -ss 00:00:01.23 -vframes 1 -q:v 2 output.jpg

15. Take a screenshot from every 1 second of the video

ffmpeg.exe -i wm.mp4 -r 1 -f image2 screenshot-%03d.jpg

16. Merging two separate audio files.

ffmpeg -i sound1.wav -i sound2.wav -filter_complex "[0:0][1:0]concat=n=2:v=0:a=1[out]" -map "[out]" soundconcat.wav

17. Extracting the audio file from the video as mp4.

ffmpeg -i source.mp4 output.mp3

18. To mute the video.

ffmpeg -i source.mp4 -c copy -an sessiz.mp4

19. Making video from photo gallery.

ffmpeg -f concat -i filelist.txt -i audio.mp3 -c:a copy output.mp4

filelist.txt sample file

a1.jpg
a2.jpg
a3.jpg

20. Writing text on the video with the desired font.

ffmpeg -i source.mp4 -filter:v "drawtext=enable='between(t,0,2)':fontsize=30:fontfile=font.otf:fontcolor=yellow:text='my text':x = (w - text_w) / 2:y = (h - text_h - line_h) / 2" output.mp4

between(t,0,2) 0-2 seconds

center the screen x = (w - text_w) / 2:y = (h - text_h - line_h) / 2

You can make it output in the position you want by giving x and y values.
