Hi gurus

Is there a way to encode/decode blackmagic 8 bit videos using mencoder or any other transcoding software on linux

I've never heard of it, but that doesn't necessarily mean anything. If there isn't any existing support, try asking on the ffmpeg-devel mailing list, and specifically Mike Melanson. His specialty is working on uncommon formats and he coordinates the efforts of several other people. If you provide him samples, show interest, and ask nicely, you'll improve the chances of somebody writing support. -Corey
