Massive green and purple glitching in exports

[defaultbfa5g52ebner]

Macbook Pro mid 2014

2.2 GHz quad core Intel i7

Ram 16 gb

OS Big Sur 11.7

Look at these exports (from same timeline): https://drive.google.com/drive/folders/1eC7FACehSax0bzKqL477ZkUraxYtl-qt?usp=sharing

The one labelled "software encoding" is the result of me deactivating "hardware encoding" for that specific export. 

It happened before occasionally, but all I had to do was to repeat the exporting (without even changing settings) and the problem would disappear. Today I re-exported my file ten times - trying different exporting settings also - and also tried to export a different video. The problem remains.

As I said, I already tried to deactivate hardware encoding. I was using the previous version of Premiere Pro, then downloaded the latest version, but nothing changed.

I'm exporting in H.264. I tried "match sourse - high bitrate" and "YouTube 1080p" presets. Progressive field. Frame rate 29.97. Square pixels.

I spent the day exporting but nothing worked. Now I'm late on my deadline and don't know what to do. Can someone help?

Please use the free MediaInfo and post a screenshot of the properties of your media in tree view:

Many users are having issues with VFR. If the file is variable frame rate, use Handbrake to convert to constant frame rate:

Here is a tutorial:

Shutter Encoder may also be used to convert to Constant Frame Rate:

Hi there!

Sorry about that. What's the source of media files? Does it happen while editing specific files? 

Can you share some sample files with us to test?

Let us know.

Thanks,

Kartika

Try to change video preview settings in Sequence Settings to something like GoPro Cineform (YUV-10 bit)

and switch renderers from Project Settings.

If you are rendering the same project over and over, maybe it's time to delete render files from Sequence tab.

Better yet: Quicktime > Prores 422 LT.

yeah sure.. give it a go as well...

I couldn't change neither the video preview settings nor delete the render files because they're both greyed out (see screenshots), but I tried to switch renderer from Project Settings and the export came out perfect. Thank you!

welcome! maybe if you change the Editing Mode to Custom, you will have access to video preview file formats
