Playback and export glitch

[Arnar Freyr Wade5FF2]

Hello,

I'm having a recurring issue with Premiere Pro 2021 where it randomly decides to glitch my footage. The raw footage has no issues at all with it, completely smooth and no glitching, but when I try to put them into Premiere to edit random glitches start to occur.

There is no pattern to the glitches, but once it decides that this part of my footage is going to have a glitch there is no way to stop it, even deleting and re-inserting the footage.

I have had a look around online to try and find some form of answer or reason as to why this is happening, and that brought me to two resolutions: delete the media cache files and update Premiere Pro. Well, the cache files are gone and the software is all up to date, but the glitches remain.

Now, the oddest thing is that sometimes, in the playback editor, the glitches are gone, and I think the problem is solved. But as soon as i export the glitches are back, right where they randomly showed up. I'd really like some form of answer, solution, or just someone online who can help me sort this out.

To clarify: Premiere is up-to-date on my computer, the RAW files are clean, the media cache has been deleted, sometimes I can get rid of the glitches in preview playback, but they are always present in the exported file. 

Files I'm editing:
Camera - Sony A7Siii

Codec - Xavc-s 4k 10bit 25fps

My computer:
iMac 2021, M1

Memory: 16gb

Thanks a lot!

Anyone still struggling with this? Im using latest version of Adobe Premiere and tried both intel and M1 version but the glitches are still in my footage?

Using Apple M1 macbook 16gb

I was using the Beta version but it keeps crashing on loading saying it has a Input Contract Issue and Adobe Help unable to aid me in fix as they dont cover beta versions.......

I have to say this is worst ive ever felt about Premiere and a whisker away from leaving this software at the moment.

Hi @Snapiesworld ,

This is fixed in the beta builds. Please download the latest Premiere Pro Beta build from Creative Cloud --> Beta apps --> Premiere Pro (Beta)

It's terrible. I've the same here. But the most "estable" version is the 15.2

Hi @igorcaiedoamaral ,

Have you tried the beta builds ?

Mayjain

[igorcaiedoamaral]

Yes, Mayajin. I've tried all option. An I also talked to an Adobe crew member by phone for almost one hour. The match between M1 and Premiere doesn't happen iet...  The "better" version is 15.2, It has some bugs, but I can work, sort of... Because, I'm editing with M1 compete setup, and I've to export my videos from another machine (Macbook Pro).

If you have some staff who speaks portuguese, I'm available for help you with some tests.  My english is terrible.

[igorcaiedoamaral]

It still terrible... I only use the 15.2 version, opening using Rosetta. This is the stable version here. Try to downgrade to thsi version

Hi @igorcaiedoamaral ,

Can you please share some sample media files which are causing this issue, if possible ?
You can drop the media files here: https://helpx.adobe.com/creative-cloud/help/share.html

I will check at my end, 

Thanks,

Hello, Mayjain.

Unfortunately this problem was happening with many different files, different cameras (fs7, 6300, alpha 7III)  and differente codecs. The problem was intermmitent and didn't have any apparent reason. But, the glitches were commom when I used prores 4444 files with alpha: watermark, lower third and nested sequence with a person doing sign language translation. Sometimes the watermark blinked or I got a white image in the RGB channels of the nest sequence... 

I can't share these files because they're huge. It was used for a "live" tv program. I'll share some inpector's prints and some prints of these glitches. Unluckily I deleted other versions that appeared other different kind of bizarre glitches...
