Strange flikkering and render mistakes using Star Generator in BCC 7

[Peter Mcauley]

Hi Itamar,

We’ve seen some results that display some flicker in the galaxies but only in the render when we have the compression turned up to a very high level. I sent you a clip of this today. When we render a full quality we do not see this issue at all. Are you seeing flickering with PTR or with a high quality render?

Thanks,

Peter.

Hi Peter, Sorry, but what do you mean by PTR? Apart from that; yes this is a MPEG2 render 4:3 SD, so high compression. I’ll try a higher quality render later this evening and report back to you

I get this same problem using Both BCC 7 and 8 in Premiere Pro CS5.5.

I noticed that in the release notes for BCC 8.0 Vegas it says this:

“BCC Stars will occasionally exhibit horizontal bands of artifacts in the star field and galaxy controls.”

I didn’t see anything noted for Premiere Pro, but this is the exact problem. There is no suggestion for a workaround either.

With Premiere Pro I have had better luck turning off hardware acceleration and doing the render that way. Though it takes HOURS just to render an 8min video (when it would normally render in 5-10min). My render settings are nothing extreme – 1080p H264 MP4 at 10Mbps.

I came to this forum hoping someone had an answer for this problem, but it seems even with the release of BCC 8, this bug has still not been fixed.

In my own experiments, it seems this bug has to do with hardware acceleration. I am currently using a nVidia 560Ti 1GB.
