I'm running pp2021 latest version on iMac pro 8 core xeon, 32g memory, 5k. I'm running two lines of gopro 8 4k 60p and editing is utterly useless. Takes 10 seconds for PP to even respond to start/stop. Audio cuts in and out. Video shows one frame every 5 seconds.
What is going on?????
[Moderator note: your post had nothing to do with the thread it was posted in. So it is split off to a new thread for best help.]
GoPro media is typically H.264 long-GOP, with a ton of compression tactics used that make playback/editing a total struggle for most computers. If you have two tracks of 60fps 4k GoPro, that would tax most computers.
Have you considered proxies to an intraframe like Cineform or ProRes, or transcoding to an editing friendly codec?
