Noise During Playback

PostThu Aug 09, 2018 8:08 pm

After working an hour or so, I experience a scratch noise at the start of each playback (see link below). I then have to quit and restart the application to get back to normal. Any suggestion what might be the problem and its solution?

What's your resolution and codec? That GPU is really on the lower edge for Resolve.

Indeed, I have an old computer with slow GPU in today's standards. I thought it would be enough to tackle a 2-minute-long movie trailer. Resolution is 1920x1080 HD and Codec is ProRes 422 HQ. Could the noise I am talking about above be related to the weakness of the GPU?

Yes. And the problem is not about length, but about resolution. You could try SD or maybe even 1280 x 720.

OK, thanks. I also have a problem of text updating itself. It took me 30 seconds going back and forth between the timeline and the inspector, adjusting and retyping chunks of it before the text was correctly displayed. Related also to GPU weakness?

Keep the window for GPU load (Activity Monitor) open and check.
