Thanks for your response. I think the hardware is ok, I’ve been using a GTX 1080 and a fairly decent SSD for a while with no issues.
I’m thinking it might be the format of some clips I’m using. All of my stock clips work fine, it’s just the vlog clips I’m using via livestream software OBS, they’re the problem I think. Even though they’re all H.264 I’ve been using this workflow fine for weeks, so I’m surprised! Any ideas do let me know! Very much appreciated.
Thanks,
Adam
