Great deal of trouble scrubbing footage
Posted: Sun Nov 28, 2021 8:28 am
I have some digital footage (1200p, h.264, 15Mbps, ~45 minutes long, 5GB) that I'm having a great deal of trouble scrubbing through. Regular video players seem to have no issues playing the footage. However when I try to move the playhead to a new section of video in Resolve (or to be fair, kdenlive or pitivi as well) the editor grinds to a halt for about 2 minutes while it does ... something. I see a tremendous amount of CPU activity in Activity Monitor for those couple of minutes, and then I can play the footage normally.
If I then try to move the playhead, the scenario replays itself...over and over again. I've tried both on an old Mac Pro 2010 with 48GB of RAM, an M1 MacBook Air with 16GB of RAM, and tried some open source editors on a dual Xeon Linux workstation with 60GB of RAM. Same result in all three places. Why is this footage cursed?
