Premier Pro 23.5 glitches on Mac Studio

[jesss73375388]

Hi there, 

I'm editing a very small project using 4K footage but have hit a wall of glitches I don't know how to solve. Premier is currently unworkable, I originally thought an imported Lut might have caused a glitch but as I tried to resolve one issue, I realised the problem was bigger. 

Glitches are:

• Zoomed in/cropped footage in a couple of shots loses all definition once rendered and ends up worse than the original clip. When that failed I tried sharpening the footage and rendering again. Same things happens. I was cropping footage like this in January this year and had no issues before. 
• Premier fails to recognise the in and out points on a sequence and exports a whole timeline regardless of what's on it. 
• When trying a workaround and copying the project on to a new sequence the quality of the original footage deteriorates badly.
• I've tried opening the project within another new project, using the beta version of premier, rolling back to an earlier version of Premier rather than using 23.5, deleting cache files, checking internet connection but the same issues occur. 

Overall it's like Premier has zero memory of how to operate normally but I'm stumped on how to resolve it, which is really frustrating given the monthly fee and the fact it seems unusable. I'm on an entry level Mac Studio with 32GB of Ram, most of which I've made available for Premier. I maybe missing something obvious and I hope that's the case. If anyone has any ideas about what the problem is I'd really appreciate it!

Premiere Pro should perform well on any Mac Studio.

What is the source footage?  For example, is it low bitrate, variable frame rate 2160p60 H264 or is it 2160p23.98 ProRes 422 HQ?  Some source footage falls apart when being exported and some source footage holds up well.

If you carefully compare how your system was configured in January, what is different now?

***Zoomed in/cropped footage in a couple of shots loses all definition once rendered and ends up worse than the original clip.  When that failed I tried sharpening the footage and rendering again. Same things happens. I was cropping footage like this in January this year and had no issues before. 

How much is the Scale value being increased?  If it's full-resolution media with a higher bitrate mezzanine CODEC (ProRes 422 or DNx) it should hold up well to about 120%.  For between 120% and 200%, send it to After Effects and to use Detail-preserving Upscale.  For anything above 200%, consider using Topaz Video AI. 



***Premier fails to recognise the in and out points on a sequence and exports a whole timeline regardless of what's on it.

When using the Export mode of Premiere Pro or a preset in Media Encoder, double-check the Range setting.  This determines what time span gets exported.

Range pop-up menu in Export mode of Premiere Pro set to export the Entire Source.

***When trying a workaround and copying the project on to a new sequence the quality of the original footage deteriorates badly.

Assuming you're copying source footage from one Sequence to another, this may not resolve the issue.  Did you create the Sequence by dragging and dropping a source clip onto the New Item icon or to an empty Timeline panel or did you choose a preset from the New Sequence dialog box?  It's important that source footage settings match or exceed the edit settings.


***I've tried opening the project within another new project, using the beta version of premier, rolling back to an earlier version of Premier rather than using 23.5, deleting cache files, checking internet connection but the same issues occur.

It sounds like this may be a workflow issue that would affect any version of Premiere Pro.

Hi Warren, thank you so much for your help and for a very quick response! I've been tied up today but going to go through all this properly tomorrow and hopefully work out what's wrong by a process of elmination as above!
