Thanks for posting your video test dsagilles. Do you see these artifacts on the raw video? Or on the video that you upload to Youtube? They look like compression problems to me, so I'd be very surprised if changing the lens helps much. If the raw video is clean, it would be worthwhile to try and identify at what stage these artifacts are being introduced. But if the raw video already looks like that, what is the point of shooting raw? So far I've never seen such results on any of my footage recorded as bog standard Canon mov.

The green/yellow artifacts are in the original RAW footage.
Yeah it's looks like a compression problem, but it's not the case because I have the same result on the uncompressed AVI out of After Effects.
The aliasing, the chroma smoothing and maybe a too strength color-grading aren't helping.
I think we can't see all theses artifacts on Canon MOV because of the compression, adding a global blur and maybe a kind of anti-alias is applied on the compression stage.
Is this RAW or H.265?
This is RAW. I was very surprise of the result quality too. On my previous videos I haven't shot wide scenes, so I wasn't able to see all theses problems.
It would be cool if someone could try out a RAW shot on a similar scene.
Trees seems to be the worst thing for our 650d RAW.
