I’v used several 5.x versions of UE but always run into the same issue on my Macbook Pro M1 max: any video media playback looks fine in the viewport but as soon as I render them out into an image sequence, the playback is very choppy, skipping frames of the video sources. The camera movements and everything 3d is smooth but the playback skips/freezes random frames. Any ideas?
Hi there @hitindags
I’m not personally up to date on the system specs for the M1 Max. But, if it meets standards and this isn’t a lag issue, I’d check the scaling.
Thank you for your reply. I found a workaround by importing the films as image sequences. It seems to be some kind of buffering problem.
What do you mean by the scaling anyways? It would be nice to come back to ProRes4444 as the PNGs are pretty annoying to work with.
I was referring to the resolution you’re using.
FullHD for the Sequence and 4k for the ProRes4444 input. I notice, that there is no green buffer bar in the sequencer when playing back ProRes. Not like you have with PNG or audio tracks.
Gotcha. Have you tried TimeSync’ing it or converting it to frames, by chance? I’ve saw this happen before on the M1/M2 chips. Unreal’s video decoding is on those can be a bit ‘wonky’ meaning the video doesn’t necessarily know what frame the engine is trying to render.
Hi there! I haven’t heard back. Were you able to get this resolved?
