- class VideoFileWriter(config={}, **kwds)[source]
Bases:
Transformer
Write video files.
VideoFileWriter
has been superseded byVideoFileWriter2
.This component uses FFmpeg to write video to a variety of formats. Make sure you have installed FFmpeg before attempting to use
VideoFileWriter
.The trickiest part of configuring
VideoFileWriter
is settingencoder
. Combinations I’ve found to work on my machine include the following:'-c:v ffv1 -pix_fmt bgr0'
– FFV1 lossless encoder, 8-bit colour'-c:v ffv1 -pix_fmt gray'
– FFV1, 8-bit luminance'-c:v ffv1 -pix_fmt gray16le'
FFV1, 16-bit luminance'-c:v libx264 -pix_fmt yuv444p -qp 0'
– “lossless” H264'-c:v libx264 -pix_fmt yuv444p -qp 0 -preset veryslow'
– same as above?
I’d be interested to hear of any other good combinations. Email me at the address shown below.
