h264 lossless / RGB-to-YUV4:4:4

NoX1911 · 14th May 2006, 22:17

I'm trying to find an alternative to TSCC (techsmith screen capture codec, vfw only) for mp4 container so i'm trying to test the h264 lossless capabilities.

I have problems feeding the encoder with the right colorspace. When i try to load up an avisynth script with RGB output an error occurs. How is it meant to be done feeding h264 CLI with YUV 4:4:4? Is avisynth capable of converting RGB to YUV 4:4:4?

If you are using x264, only supports YV12 4:2:0. Avisynth can convert to YV12 by using ConvertToYV12()
