The crazy thing is when you vertically stack the two videos together,
then the colors become again identical in the output:
ffmpeg -i out1.mp4 -i out2.mp4 -lavfi vstack -y out.mp4
Sorry, I have no idea for a solution or workaround.
To make things even more confusing, Media Player Classic
zscale=...,format=yuv420p
O okay. I tried that before (except using two -vf commands), because I
suspected you might've meant that.
Just tried it again, still no luck. Let me know if I need to tweak anything:
ffmpeg.exe -f lavfi -i color=0x19be0f:s=400x578 -crf 0 -vcodec libx264 -vf

Unless I'm somehow misusing zscale (which is a possibility), it would seem
as if the
problem lies elsewhere.
If you do not use format filter after zscale it will not work correctly.
Do you mean using the "filter" keyword under the zscale property/variable?
I tried this, again no luck (also

Using the latest 5.1.1 "essentials build" by www.gyan.dev.
Hi all, I'm a beginner to ffmpeg so I'm having a hard time believing that a
utility so old and so widely used has such a fundamental bug, but the evidence
is staring me in the face and leads me to no other conclusion.
