Unexpected color flashes on export frames
on Sep 12, 2012 at 6:48:42 pm

Hi,

First time actually rendering out of Davinci Reolve 9 (Lite) and I'm getting all these strange color flashes on quite a few frames here and there.

Example: frame

Specs I'm using:
Macbook Pro 17"
2.5 Ghz i7
16 GB 1333 Mhz DDR3 RAM
Lion 10.7.4
AMD Radeon HD 6770M 1024 MB

Is this a hardware issue?
Anyone else experienced this before? And know how to fix it?!

Thanks!

That looks like potential clipping.... If not, I believe I read on here a while back about throttling down the render speed (you can do that on the screen you set your renders on) and that stuff going away.

Hi Stephan, I had the same problem with the same computer. It is the AMD video card and the Lion version you have. To correct this I upgraded to Mountain Lion and the problem was solved.

Hope this works for you too

Good luck

Hi,

I posted over on Blackmagic's own forum too and someone recommended the same thing, so I set about downloading and installing Mountain Lion (which was no mean feat down here in the jungle of Ecuador I can tell you).
It seems to have completely solved the problem.
Thanks for your responses.

Cheers,
S
