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.
Thanks for the details. Try running the app in Rosetta mode & let us know if it's working properly. Also, if possible please share a download link for the sample media with which you are experiencing this issue. It will help us diagnose the issue properly.
I'm having the exact same problem with my Fuji files. Using same settings as the starting post. No problem playing H.264 files. But H.265 will not play in the source monitor (but will in the Program monitor). I have spent almost a full day trying to get files from camera to play without success. Very difficult to find info on what to do. Using proxies has not helped. And using Media encoder to transcode eroded the quality too much. Is there a guide available? tks.
I'm having the same issue with my Fuji files. It's unusable in it's current state. Lowering the quality to 1/2 or 1/4 makes it even worse and choppier. Seems like an issue with Premiere not utilizing the M1 Pro/Max decoder. I have to transcode everything. These files play back perfectly fine in Finder or Final Cut Pro.

h265 if a bear of a format, heavily compressed to get high quality with small file sizes. I'd try transoding to prores 422 or prores 422hq. Rachel, what format are your proxies? Any all iframe format like any of the prores formats will probably play much better.. You can also downrez your proxy files to 1080 which will also probably help.
Transcoding the footage to ProRes makes it very smooth. But the whole problem is trying to avoid doing that since the M1 Pro/Max has an engine dedicated to decoding these HEVC/H.265 files. The fact that I can edit perfectly smooth with no transcoding in FCP proves this.
am I surprised that apple's app does a better job handling the video format of the iphone... no. FCPX is a very different beast than premiere and we're in very early days with the M1 Pro/Max chip... and I'm guessing Apple had access to how the chips perform etc way before Adobe did... I'm sure Adobe's working on this, but probably a good idea to either transcode to an easier to digest format or work in FCPX. BWDIK...

Hi everyone,
We have reported this issue to our product team & we will try our best to get it addressed as soon as possible. For the time being, you may either transcode the files to an edit-friendly codec like ProRes 422 or use the previous version of Premiere Pro (v15.4.1).
After weeks of trying, still unable to edit h.265 footage in Premiere (22.1.2). Your suggestion to use previous version 15.4.1 doesnt work - it says I'm unable to open projects in a previous version. And transcoding using media encoder fails. Very frustrating.
and perhaps you can try using the previous version of media encoder to transcode... since that would remove the necessity of opening a project in an earlier iteration of Premiere...

Hi everyone,
We've been working on optimizing the playback of XT4 HEVC 10 bit 4:2:0 files. Would you mind trying our latest Beta release of Premiere Pro & checking if it's working properly? You may refer to thislinkto know more about the Creative Cloud beta program.
hi, yes I have been using the beta version since the day i posted this. It's much better playback actually, then there are other bugs like it takes forever to save the project or it often crashes but i really hope that this version will be released as soon as possible and that it will improve.
Cross posted here- On the M1 Max 22.3.0 Beta performs better than the non beta version in playing back HEVC, but it is still so choppy that it's not functional to use as an editor for this type of footage. Using J,K,L transport control fails miserably and some footage just doesn't play back at all. This is after a cache clean and waiting for my file to update media (from 2021 to 2022 beta). Point being, not a solution (for XT3 footage, at least). Sticking to 2021 for now.
Any updates on this? It's 3 months later now but I'm having the exact same problem with my Fuji h.265 files. Only difference for me is that I'm using a Lenovo x1 pc. If I render a clip it plays fine but any slight change makes it go back to being super chopping and mostly just audio.
Sorry for this problem. We have fixed this in the latest beta builds and this is also on track to be available in normal builds. We will update you soon.
