[HELP] AviSynth 32 bit - ColorMatrix filter not working for video?

[The_Tinkerer]

I tried to test with VapourSynth, and didn't get very far... it appears image stream input for VapourSynth is completely broken in Hybrid 2020.10.28.1. It throws an error even when trying to display the script (tried with both PC and TV luma ranges and bt709 color matrix):

OK, I checked the mp4 output in Hybrid 2020.10.20.1, for 32-bit AviSynth ColorMatrix 709->601. It works, and is correct.

SO, in Hybrid 2020.10.20.1, when running 32-bit AviSynth ColorMatrix 709->601:

- Wrong color palette in previewer
- Correct color palette in mp4 output




In Hybrid 2020.10.28.1, there is no change in the color palette at all, in either the previewer, or mp4 output, for 32-bit AviSynth ColorMatrix 709->601.


Here is a log for Hybrid 2020.10.20.1 for mp4 output, with the 32-bit AviSynth ColorMatrix 709->601 filter:
