Premiere Playback Problem (reverse playback)

[janl80899295]

Hi,

I'm having problem with playback. When I go through material, playback is smooth, but if I want to go to reverse playback (J on keyboard), playback is choppy and unwatchable. Before now I never had that problem 😞 (and it doesn't matter if I edit raw or proxy files).

Premiere that I'm using is 22.4.0 on MacBook Pro, M1 Max, 32GB RAM, 1Tb.

Thank you for all your ideas!

Best regards!

Jan

Hi, I have the same problem with Premiere 22.4.0 on Mac Studio M1 Pro, 32GB RAM, 512 GB.

But I noticed, that problem with reverse playback takes place only when I'm working with clips  XDCAM HD 422 1080i50. 

With another codecs (e.g. Pro Res (HD), H.264 HD), IMX 50 (SD)), everything works fine. Playback is smooth both forward and backward.

Regards, Thomas.

Hi Jan!

Sorry to hear that. Does it happen on a specific project? Have you tried deleting cache files? Also, let us know the source of the media files.

Thanks,

Hi,

most of the projects that I'm working on at the moment are 1080p25. Proxy files that are ProRes422LT works fine (also files for Arry Alexa (ProRes4444 4K)) problem starts with H264 MP(4), 1080, 25fps. I thought that perhaps some plugins were the problem, so today I formated MacBook Pro and started from scratch, installed Adobe CC, but problem is the same. So I'm guessing that the latest Premiere has same issues with H264. Performance of my mac is perfect. Scrolling through material is perfect (even in 6K Red Raw). Just when I press J to go reverse playback or if I change the speed of the clip to reverse, playback is unwatchable.

Thanks for the information. Could you provide sample files to test? You can upload them here: https://helpx.adobe.com/creative-cloud/help/share.html

Let us know.

Problem started on Premiere 22.4 for me as well with XDCAMEX files wrapped in .mov, however when I record in .mp4 no issue. My current fix is to roll back to a version prior to 22.4

Yeah, I have this problem as well, if I want to reverse a clip using speed/duration it does not even come close to playing back. I have a M1 Max Macbook Pro--everything else is buttery smooth. @Kartika Rawat please look into this! 4K .mp4 file HEVC 10 bit 4:2:2 off of a Canon R6. Thanks! Premiere 22.4.0 build 57.

Has everyone having this issue had tried ProRes source in a ProRes Sequence?

For example, if we transcode to ProRes 422 LT and then set Sequence Video Previews to ProRes 422 LT, everything is responsive and fast.  The yellow line above footage in the Timeline appears much less frequently (and at times not at all).  M1 based Macs should be able to convert 60 minutes of camera original footage to ProRes within minutes, an edit exported to the "Match sequence preview settings" is extremely fast, and exporting to ProRes Proxy, H264, and H265 is faster.

I don't think it's an issue of adjusting a setting, I think it's a bug that appeared in version 22.4 onward for both Windows & Mac users.

ProRes works extremely well in every version of Premiere Pro - even before it was  natively supported.

A best practice in video post production is to match your source settings to your edit settings to your edited master settings - at least if looking for a fast and stable workflow.
