Video begins to glitch then turns green during edit

[#1]

I'm using Mac with Catalina OS 10.15.7, Premiere Pro 14.6.0

Graphics: Intel Iris Plus Graphics 650 1536 MB

I was editing a 5-minute video. At 2/3 the way through, I made a cut and the untouched clip began to show a glitchy band at the top of the screen. After a few more slices, the video turned green. 

The original video plays fine end-to-end. I exported the edited video in hopes that the glitches would not also export, but that was not the case. 

I thought it was the graphics card and changed computers. Still having the same issues on this one.

I'm up against a deadline with a few more videos to edit. Help!

Thanks. This is what happens when you let elderly people use computers!

What's the origin of the video you're editing?

[#6]

One video came from Zoom and one came from QuickTime.

We developed a workaround. 

1. Import the video into iMovie

2. Export from iMovie

3. Import the iMovie version into PR and proceed as usual.

It's clunky and takes more time, but at least I can get my work done. 

This is happening with random videos, not every time.

Yeah I suspected it was a screen recording. Premiere, and other NLEs, really hate working with variable frame rates, which screen recordings usually are.

You can use Handbrake, it's better than iMovie to do the converting.

Thanks for your help.

It's odd to me that it's only now becoming an issue. I've edited a few hundred videos that were a minute or two in length all the way up to 3 hours. This is the first time I've encountered this. 

I use Handbrake to reduce file size for upload to our LMS. I pull the video in and turn it out as an MP4. Do I need to do anything special in HB to convert? 

(I work for a startup company where the thinking runs along these lines: Hey, you own a car. You'll be our head mechanic! 

I had a recording studio. That got me elected as the audio/video engineer. YouTube is of some help. LinkedIn Learning and Udemy also helped. Two years ago I thought adobe was something with which to build a house in New Mexico!) {Best job ever, btw!}
