Sharpen and Rhea is special; as higher you set sharpen in Rhea, the more pixel blocks are broken down. If the value is too high, this leads to a loss of contrast. Sharpening can be counteracted with increase of anti-aliasing.
What are your replying on ?
The only problem I’ve got with Rhea and 8K files is outputing to FFV1 10b 4:2:0
I can encode manually with ffmpeg but with TVAI it fails claiming a “Resolution problem”.
To me the problem is here :
-level 3 -c:v ffv1 -pix_fmt yuv422p10le -slices 4 -slicecrc 1 -g 1
-g is way too small, it results in buffer underload, and too much keyframes are generated
-slices 4 is not well tuned, and shoul be synced with CPU available threads
No -thread used, unfortunately it is essential for Level 3
The post is even not investigated … Nobody gives a f***k
