Video Editing

Here are some useful code I used to process videos in the terminal with ffmpeg.

I find memorising those command being simply impossible.

Here are some handy cli scripts I use to cut videos.

ffmpeg -i video.mp4 -ss 00:00:10 -t 00:00:20 -async 1 out.mp4

ffmpeg -i video.mp4 -vframes 1 image.png

ffmpeg -i input -vf eq=gamma=1.5:saturation=1.3 -c:a copy out

ffmpeg -i file_2 -an file_2

ffmpeg -i <input> -filter:v fps=fps=30 <output>

ffmpeg -framerate 15 -i image_%04d.png -c:v libx264 -r 15 -pix_fmt yuv420p out.mp4

ffprobe -v error \
-select_streams v:0 \
-show_entries stream=nb_frames -of \
default=nokey=1:noprint_wrappers=1 \
video_name

ffprobe -v 0 -of csv=p=0 -select_streams 0 -show_entries stream=r_frame_rate
