video export is glitchy, distorted

When I export my video, certain moments will have a glitchy/distorted overlay on them, as if the video has struggled to process certain clips. What's frustrating is that when I reexport, it can be in a different spot and NOT in the same spot it was before. But alas, it's always SOMEwhere as the video i've made is 5 minutes so it seems impossible to luck out with 0 glitches... Here's a picture of what it these brief glitches look like:



It looks as though it's pulling a still image from an earlier part of the video (not a bordering clip). Sometimes this happens in the timeline when i'm watching before i export, but it goes away if i just pause and replay that section again.


This has never happened before and I used iMovie every other month or so.


Has anyone experienced this or know what I can do?


My specs are:

iMovie 10.1.14

macOS Mojave 10.14.6 (not going to upgrade to Catalina because many of my apps will stop working)

iMac Retina 5K, 27-inch 2017

4.2GHz Intel Core i7

24GB 2400 MHz DDR4 RAM

Radeon Pro 575 4 GB

iMac Line (2012 and Later)

The pixelation issue has been raised several times on this forum since the Catalina upgrade occurred. it may be a bug that Applie will need to correct.


The problem appears to occur with videos made on the newer iPhones in the HEVC format. The workaround is to use a video converter such as the free download Handbrake to convert the video clips to H.264, Mp4/AAC, that Handbrake will do by default.


You can get Handbrake here:

For future exports from your iPhone you can go to your iPhone settings Photos/Transfer to PC or Mac and select Automatic to export in a more compatible format.
