sound noise in color page

PostSat Jun 02, 2018 5:48 pm

Hi All,

I created a simple timeline with few clips (30fps).
Each clip speed is reduced to 90% + optical flow
I added a 48Khz 24bit audio track. In edit page the audio track is smooth, plays good, in color page exactly whe the playhead jumps on each clips I hear a noise, the audio get distorted for few milliseconds. Each clip has the same color correction + motion blur.

Resolve Studio 15B4
Windows 10
audio through the Nvidia hdmi plugged into the hdmi of a LG 21:9 monitor

What does the system audio sound like?
Do the clips play at 30fps in color page?

yes, playback is smooth in color page, only the audio crackles when the playhead jumps on each clip then it plays normally. I have cuts, not cross dissolves. Let’s say the cuts generate an audible noise.

Ok, and with system audio?
It sounds like you are still testing with the NVIDIA HDMI out, which is not recommended
