Still images become pixelated and splotchy after exporting a long video

Hello! I am having issues with a few still images after exporting an hour and 20 minute video from Premiere Pro. The images become very pixelated/blurry and the colors turn to grey in splotches. When I export the same part of the video with the same settings in a shorter video, the issue is not there. Some of the images start out splotchy and then clear up after a few seconds, and vise versa. When editing in Premiere Pro, everything looks normal. It's not until I export the long video that the distortion appears.

 

Here are some screen shots of the issues. 

Before export:

After export:

The pixels also fluctuate. Here is an example of an image that starts out distorted and then clears up seconds later.

I tried switching from Renderer: Mercury Playback Engine GPU Acceleration (Metal) to Murcury Playback Engine Software Only, and that did not fix the issue.

 

Here are screenshots of my export settings.

I have thought it may be the Variable Bitrate, but I'm not sure why that would be fine when the video is shorter and then cause pixelation when the video is long. 

 

If anyone knows what the issue is, I will be so grateful! Thank you!

Nothing looks unusual, Hannah. I'm a bit stumped. Can we know more about your computer system's components: CPU, GPU, RAM, and so on? Are you meeting system requirements?

 

Thanks,

Sorry, it's your Graphics card that is giving you grief, Hannah. It's only 1536 MB. It needs to be 2000 at a minimum. And when you press on it, you really need around 4GB for general purpose editing, especially exports. You aren't meeting system requirements. You'd need to have a good working system for a solid export for such a long sequence and with potentially overly large images. I am surprised that changing to Software Only didn't help. You might try an export to ProRes LT. using Software Only You'll need around 50GB. Here's the calcualtion I used. Otherwise, you might be able to use smart rendering, but you'd need 100GB free.

 

Thanks,
Kevin

Thanks for pointing that out! I tried using a Blackmagic eGPU 4GB, and it improved the issue but didn't fix it completely. I will try clearing some space on my hard drive, maybe edit the original still images if they are too  big. I'm also not sure why software only didn't help.

Would it have anything to do with the interned I'm connected to or the storage available on my computer?

are you saying your sources are still images?  If so, what are their pixel dimensions and are they rgb?  

If the sources are video, please tell us the source properties and the camera or other device they were recorded on?
