Hello I have Anormal Artifact when GPU-acceleration is enabled, more with complicated shader but also with standard shader ...

SVP 3.1.5
MPC 1.7.2 (i use lav supplied with it)
ffdshow / haali spliter / avisynth supplied with SVP

It is frame borders artifacts. Appears with GPU acceleration when frames has thin black borders.
We work on the artifact fix but it is complicated issue and I not sure if we can fix it for near time.

By now you can avoid these artifacts by enabling black borders crop: SVP tray menu - Frame crop.

I recommend one of two values in your case:
- By four pixels on each side
- Custom - enter 2 in each field - Apply

It's OK with black borders crop, thanks !
But a fix would be better, because sometimes in some scenes black bands may appear ...

Another quick question, I try the best profile to encode (in 96fps or 120 fps) with "max smooth" and "min artifact" ...
Is this profile is improvable ? :
