Fuji X-T4 h.265/HEVC files very laggy in in Premiere 22.0.0 (Build 169) for Apple Silicon

Report · Dec 03, 2021

First time editing video on my new Macbook Pro M1 Max.

Any of the h.265 video's I import into my project then drag into the source monitor play in a very very laggy fashion. The video just freezes, but the audio can continue.

No issues with h.264 videos, and it obviously works if I convert the h.265 into apple prores - but i really don't want to have to do that for all my clips.

Any idea's if this is a priority fix?

System info:
Apple Macbook Pro 14 inch

M1 Max 10 core

32 core GPU

64 GB ram

MacOS Monterey 12.0.1

Will try on my windows PC also - but apparently a common problem across the board since early Nov and the Beta testing. A lot of X-T4 users out there.

Was having the same issue. Footage was essentially unworkable unless I rendered in the timeline. But it's buttery smooth within the Beta. Working on the M1 Max. If you're struggling and need a workaround until the next update just download the beta. Will save you a ton of headache.
