Why did you choose fast decode mode? It's a big hit to compression.

5D Mark II records in 4:2:0 H.264 (definitely not raw) already, and while bitrates are fairly high it's not exactly perfect. I'd question the benefit of transcoding this into HEVC for archival purposes. Is storage really that much at a premium for you?

DV is super inefficient (25 Mbps for SD) by modern standards, so you can easily cut that down to no more than 10 Mbps with HEVC I'm sure. The tricky bit here is handling the chroma correctly. DV uses 4:1:1, so whatever tool you're using will need to do a good job of converting it into 4:2:0.

Post a sample of the "degrading difference on the final result (in green areas)" if you'd like feedback on improving that. It may or may not be due to compression.
