Strange flashing during playback and render

PostSat Oct 14, 2017 1:33 pm

Hello,

Davinci Resolve 14 Studio
Version 14.0.1.008 (up to date as of this post)
OS X 10.11.6
NVIDIA GeForce GTX 980 Ti 6gb VRAM


I'm grading 4K clips shot on a Canon c300 and recorded on a Shogun in ProRes 422 HQ

Whilst rendering output ProRes and H264 I noticed strange white light flashes appearing on the film both whilst exporting and in the exported movie file.

I reduced the render speed from max to 90, then 50 and all the way down to 1 and the problem hasn't gone away.

CUDA is also updated.

In a bit of a jam here, as I need to deliver this out, as of a couple hours ago.

Any ideas?

I apparently can't seem to post a url link in this forum to the video in youtube! so I've tried to attach it here. .mp4 not allowed! trying jpegs. fingers crossed.

I was able to get this out the door, by using Resolve 14 Lite Public Beta.

But I'm seriously concerned that the paid version is causing such issues.

I also realise the flashes may not be very obvious in the screenshots provided above - the best way is to see the video :-(

Jignesh, please take the time to call BMD Support and raise a Problem Ticket. Kudos to you for even thinking the beta would solve a problem in the final release.
