Encoding artifacts


We are experiencing artifact on notchLC compressions made on After Effect from a prerendered image sequence. Those artifacts are showing no matter what enconding profile we use (even Best). It seems to happen a lot when there is solid color blocks in the source.

Any idea on what causing this and possible solutions / workaround?

another exemple, source VS compression

Thats super weird - if you could upload the file your working with, either here or to Support, I’d be interested in taking a look.

Hey Ryan,

sure, we can provide several sources. I opened a ticket with a 3sec png seq in attachment. On that source, the artifacts appears in the forehead of the red lady (like the screenshot above) after compression.
