Premiere Pro won't stop compiling my storage into oblivion

[evanf28996720]

99/100 times Adobe Premiere Pro works perfectly for me. This suddenly happened today and I don't know what to do. 

I was rendering another video when I suddenly got the error "Error Compiling Movie". It's an error code 4, meaning no storage left, which is weird because the file was not big and I know I had +200GBs of storage free before rendering. I deleted 50+ GBs anyway but then ended up in the same result with my document file show 50+ GB more full than before. 

What is it doing and how do I fix it? My clients need me to export these so they need to be done asap. Thank you for help.

Quick Update: I've found the files of the rendering, which were up to 100+ GBs.  I use the same sequence setting I always do, but I've included a picture of them here. Can anyone tell what part of it is making the files so huge?

Hello @evanf28996720,

I read your note. I think I understand what you are having trouble with. Thanks for the screenshots, as they are telling.

Change the codec for Video Previews in Sequence > Sequence Settings to QuickTime > ProRes LT. The iYUV codec is very old and inefficient. You should also delete video preview files after completing a project, as they can be pretty large with ProRes LT. It's a much better codec for editing.

It is also better to use a standard-size frame size for Sequence Settings, like 1920 x 1080 for HD. Your video preview settings should match that frame size.

I hope this info gets you back on track.

Thanks,
Kevin

You are also using an unusual frame size.
