Artifacts with levels Vegas 11 (521)

Zanoonga wrote on 2/7/2012, 8:18 AM

Hello!

When I put a video layer on top with RGB-adjustments to compensate for the SRGB-gamma on the layers below, it produces a weird posterize effect in crossfades, sometimes eliminates them.

Is anyone else having this problem?

yes, see 'Sony Levels posterize effect issue' on my thread, sounds the same.

Paddy, thank you!

And it also effects one build before 521 but is clear in 425.

I really appreciate the feedback - well done guys.

Paul.

Zanoonga, looks like you may get your fix! (and a lot of other people too).

I like how the posterize issue was handled. We described the problem and provided video showing how it happens. SCS jumped on it and is fixing it. There was no whinging on our side and SCS recognized right away that we had done a good job identifying the bug, that it was easily repeatable across many machines. Now it is being fixed.

Yes, thanks for that. It also explains why some do not see the problem. My GTX460 does show it.
