8 bits grayscale codec needed!

Hello everyone,

does anybody knows a 8 bits grayscale codec or can indicate me where I
can search for such video codec??

I already read something about this issue in a post of year 2000. But
I believe that there is probably new answers for that question now!

I have several 8 bits grayscale sequential images that I want to
compress and put together into a video! How can I do that??

Thank you very much!!

paq8i (but no other versions) has a grayscale model for PGM files.

Hello, the idea is exactly what ffmpeg does - " take a sequence of
sequentially numbered still frames and encode them as a video". I want
to explore redundancy between sequencial frames. I hope to compress
them better than if I compress them individually.

Thanks for answering (Pete and Matt)!
