Hello Michael, Many thanks for your answer Sir!
It interests me a lot that the NHW Project algorithm would be studied for the great FFV1 codec! Just first I wanted to point out that the NHW Project is very experimental for now.For example there is no lossless mode and it is now only for 512x512 image size... Do you plan to add to FFV1 a lossy intra-coded picture mode? Maybe first and before going deeper, you can try the NHW Project and see if in its current state it can be interesting for FFV1? Many thanks again!
