====== Video filters ======

Video filters alter the video. Of course they can only have effect if the video is not in copy mode (Copy means "do not change the video"), so the first thing you have to do is [[using:main_window_-_qt_version#audio_video_sidebar|select a video encoder]] (something else than the default "Copy" option for video). Then, in the main window, clicking the Filters button opens the Video Filter Manager dialog where you can add filters.

If video has a selected encoder other than Copy, the processing chain is:

  - Extract [A,B]
  - Decompress frame
  - Postprocess if needed
  - Apply all filters starting from the 1st one
  - Compress using the selected encoder
  - Writing according to the selected output format

Filters are split into several categories:
