The crop filter crops the input video to given dimensions.
-vf "crop=in_w-16:in_h"Crop 8 pixels from the left and right borders
Uncropped 1 | Cropped 1 | Uncropped 2 | Cropped 2
The decimate filter drops duplicate frames at regular intervals. If we have a 29.97fps progressive source where every 5th frame is a duplicate, we may want to apply this filter to discard the duplicate frame. This will produce smoother playback, and these duplicate frames may suffer from blending.
The gradfun filter aims to fix banding artifacts by interpolating and dithering the gradients introducing the bands.
gradfun is designed for playback and may introduce Moiré patterns. Be selective if using this filter.
No video filters | unsharp | gradfun introducing Moiré patterns
The hqdn3d filter aims to reduce noise and produce smoother images.
Addressing minor temporal noise with strength setting -vf hqdn3d=0:0:3:3
The scale filter resizes the input video.
-vf "scale=-1:720"Downscale video to 720, preserving aspect ratio
The subtitles filter draws subtitles on top of input video using the libass library.
ffmpeg -i "input[input].something" -ss hh:mm:ss.SSS -to hh:mm:ss.SSS -pass 2 ... -vf subtitles="input\[input\].something" ...TODO
The unsharp filter sharpens or blurs the input video.
Address blurry videos with -vf unsharp
TODO
The yadif filter deinterlaces the input video.
Deinterlace with -vf yadif
TODO
The timeline editing filter allows filtering of certain timestamps.
-vf somefilter=enable='between(t,52.428,55.347)+between(t,82.166,83.792)',someotherfilter=enable='between(t,82.166,83.792)'
