While I haven't done robust troubleshooting yet -- I've had two projects in a row now where GoPro events on my multi-take multicamera track got shifted by some amount -- sometimes as much as appx 30 seconds (not minor frame-slippage), and we're pretty sure things were aligned within a frame or two to start.
In both projects it was our GoPro footage that this happened on -- 7 cameras in total, two of them being GoPros, probably both shot 2K or 4K. It's possible I built the multi-camera multi-take track before creating proxies (in case that makes a difference here).
Has anyone seen this happen before? Just trying to get some preliminary theories here.
