Yellow glitching and screen tear after H.264 export in Premiere Pro 2021 on M1 Mac Mini 2020 8GB.

Hi guys, I'm having a serious issue with exporting 1080x1920 videos on my M1 Mac Mini.

 

Premiere Pro is fully up to date (as of 15.09.2021). the videos are fairly long in length - between 40 and 50 minutes, and each have nested sequences of .mp4 alpha layers, a few alpha layers for graphic countdown timers and some PNG files.

 

In terms of effects, very small layer masks with motion tracking (top right of screen to hide a title that slides in and out behind a timer) and some slight colour correction for exposure but nothing heavy.

 

There are two main video layers (camera 1 & 2), and 7 tracks for .mp4 alpha animations and nested sequences. (see screenshots)

 

I have had some success with exporting the alpha tracks seperately as 1 big animation file, and then baking the two together, but it still sometimes causes glitches after export (and adds 40 minutes per video to export), while I have 6 hours of content to deliver per week.

 

I have seen slightly less glitching by using Premiere to export natively as opposed to using Media Encoder, but this obviously eats up workflow.

 

To be clear - there are absolutely no glitches in-program, and playback is perfect. Rendering is not an issue either. The glitches only appear post-export on the final files. Mostrly they are 1 or 2 frames of an entire yellow screen, similar to the 'Media Pending' screen. Sometimes certain elements of the video glitch by themselves.

 

Footage was shot on Canon 5D Mk. IV's - 1080x1920 @2926_2.97fps, and the sequences are all set up as the same - 1080x1920, 29.97fps. Its definitely not a footage issue, as I can export the footage without error.

 

Export settings are H.264, Custom (Max Render Quality, Max depth), VBR 1 Pass. I am currently trialling using software encoding only, as I have tried just about everything under the sun using Hardware Encoding but not found a fix yet.

 

Any help will be greatly appreciated!

 

Many thanks,

 

Mike Savage.

Hey Warren, thanks for your message. 

 

How I eventually got around this problem -

 

1. I disabled all video and audio layers

 

2. Exported the graphics and overlays layers only, with the following settings:

 

Format: Quicktime

Video Codec: Animation

Render: 8PBC + Alpha

 

This basically created a full length animation file with all of the timers and graphic motions with a solid alpha background.

 

3. I then imported this new file, placed it over the video layers as a single layer, removed alpha, and then rendered and exported all as H.264 with VBR 2 Pass - target 15 max 20 kbps.

 

This gave the highest resolution export on both the video layers and animation layers while keeping the file size down, and eliminated the glitching.

 

It was a bit of a long-handed workaround, but it ended up eliminating the glitching and the client was happy.

 

Took up a heck of a lot of disk space and render time, but it got the job done.

This is for a fitness video that will be sold, correct?

 

Transcode everything to ProRes 422 LT.  Make a duplicate of your fine cut (the Sequence that you're exporting for your main edit).  Select all of the video clips, right-click and choose Render and Replace using Inididual Clips, QuickTime, Match Source - Apple ProRes 422 LT.

 

You'l need about 700MB per minute of video for storage.

@Mike Savage 

Thank you for sharing what worked for you.  Doing a graphics only pre-export was a clever workaround.  I wish I had en extra $5 for every time things are going great while editing and somehow glitching on export.

Hey guys, I just came across how to recreate this glitching in-program.

 

With the colour workspace open, and comparison view on, when I begin playback, the source screen begins flashing like crazy. It looks exactly like this on some exports. Others it is less, but still there. Rendering the area first does not solve this.

 

I have attached a quick screen recording that shows this.

 

Hope this is helpful to diagnose!

 

Thanks again for all your help.

I was able to get rid of the yellow screen glitch thing by rendering via Premiere rather than with Adobe Media Encoder.

This majorly sucks, but at least it works for now.

Hi Mike, I would do a Render In to Out 1st so that it won't be so heavy while exporting.

and if you fond the glitch during the Render In/Out, you can try to clear the render cache and render again to see if that solves the proble.

Also I notice that you're rendering using software only, is there a reason it's not set to hardware ?

 

Hope this helps.

 

Cheers.

Hey there, thanks for your comment.

 

Render settings are normally Hardware Acceleration (GPU) selected, however as I have been trying so many different methods you might have seen software was selected on the screengrab, just one of the many settings changes I have been trying, to diagnose.

 

I normally render the entire completed video before exporting, but have found this also doesnt help, the glitching still appears after export.

 

I have just cleared all Premiere settings and cache so will see if that has helped when I export out files this evening and let you know.

Did you try exporting by unchecking the Max Render Quality & Max depth settings? if not try exporting it onces without these options checked..if it does not get fixed then trying exporting using Adobe Media Encoder.

Hi Vishu. I am finding that using Media Encoder makes it somehow worse. I have tried many different options, checking Max Render and Max Depth on and off, only one on and one off, etc. I think I have tried just about every option I can think of, but the problem still persists.

 

Any other options that might help?
