Unable to export without artifacts in video

I get artifacts in my image when exporting from premiere pro. They look like extreme jpg compression artifacts sometimes, and other times they look like someone splashed green or black across the canvas coating most of the pixels with just enough pixels left behind to know what's going on even though it looks like trash.

 

I've updated all my drivers. Uninstalled and reinstalled adobe. Cleared my cache. Tried exporting without GPU. What's the point of having super powerful software if the final output is unusable???

 

It's so random and frustrating. The artifacts are never in the same timepoint in the video either so I have to rewatch 45 minutes of content every time I try something to see if there's an error. Then I get to have the same fun problem again next weekend.

 

For charging people $80/month, this is completely unacceptable. There are numerous posts about this for YEARS I've found trying to troubleshoot this. I'm about at my wits end and ready to start learning another software package from scratch.

Import the 5.5 Mbps clip into an After Effects project.  Create a new Comp from Source Footage.  With the resulting Composition in focus, choose Composition > Add to Render Queue.  In the Render Queue tab, make sure that the Render Settings template is set to "Best Settings" and that the Output Module template is set to "Lossless".  If using the current version of After Effects, set the Output Module template to "High Quality".  Use "Output to" to name the resulting file and set a location for it (the file size going to be large).  Save the AE project and click Render.

 

To view the resulting file, you may have to import it into either Premiere Pro or After Effects.  Assuming it transcodes without the picture falling apart, replace your 5.5 Mbps source file in Premiere Pro with the corresponding Lossless or High-Quality file.

since its intermittent, i propose disabling hardware decoding or even using free shutter encoder rendering out to prores to fix any decoding issues when imported back into premiere.

Highly compressed, low-bitrate source video tends to fall apart when exported.

 

Professionally, your bitrate should be 35 Mbps or higher.  Many prosumer devices max out at 21 Mbps.  You might be able to get by as low as 14 Mbps, but I would avoid anything as low as that.

 

MediaInfo is a great cross-platform application for displaying technical data like bit rate.

That is a neat tool, thank you. I am way under your worst case bitrate (5.5 Mbps). Are there optimizations/features that I can turn off to prevent this from happening?

An example of the artifacts (the black bar at the top is blurring out NSFW stuff, that is not part of the export issues)

The same artifacts appear in premiere pro during editing too. Again completely randomely. Clicking to other parts of the timeline and returning can make the artifacts disappear... sometimes. Letting the video play through the affected segmetn can fix it... sometimes. Other times the same artifact remains, or even a different set of artifacts appear.

 

Sometimes the artifacts in export appear at the same time as the artifacts that appear during editing. Sometimes they appear at entirely different times.

 

How can I troubleshoot the problem when the problem isn't even repeatable despite it being an extremely common occurence (for me).
