The last few days I've had artifact issues with encoding a VC-1 blu-ray source. I must have re-encoded a dozen times with different settings trying to figure out what was wrong. Even tried handbrake to no avail. Eventually I tried a lossless h.264 encode using CRF 0 and I still had the artifacts. Googling seems to point to a decoding issue:

So I installed XMedia Recode and I selected the DXVA decoder for VC-1 in the settings and I'm now saving it as a lossless jpeg. The preview did not show any artifacts. If it remains clean I'll use RB to encode that to x265.

Atak, I never knew of this issue with VC-1. Reading the thread says using the MS decoder solves the problem. Is it possible to implement a solution that solves the decoder problems for all VC-1 sources. Looks like ffmpeg might have just fixed this bug very recently as well.
