How to combine 3 already exported videos into 1 without re-rendering - Premiere Pro 2020

[Jasiwardas]

Hi. My machine crashes when I try to export my 18min 4k 60p Video. So I exported it into smaller vids. How can I now combine it in a way that it doesn't get rendered again  - my machine would crash as with the initial try (of course). 

This seems obvious but I can only find questions about combining clips, not videos. 

So with what settings can I achieve that? Thank you for your help. It is much appreciated!

I'm not sure there is a way. That's perhaps a "muxing" process, and there are muxing/re-muxing apps out there.

Wondering what was causing the crash with exporting the full file?

Oh ... did you try setting the sequence preview format/codec to an intraframe output format/codec? Like a mid Pro-Res or similar? Then, for exporting, if the export is to the same intraframe format/codec/settings, you can use preview on export to avoid encoding the whole file.

Often if you do that, and re-import that file, you can then export without difficulty to any other format/codec as all the grunt work has already been done.

@R_Neil_Haugen I truly didn't think about that and did not check the preview format of the sequence. I will check that when I'm working on the next video on the weekend. Thank you for that input! 

So, I kind of solved the issue in a different way - trying to lower the load. When I add the smaller portions into a new project and pre-render everything it takes some time, but it doesn't crash! So this might be the closes to the intelligent render it can get. 

So if you run into a similar issue, break the vid down into smaller chunks, export those, close the App, clear media cache unused files, open the app, and make a new project, add your previously exported chunks, pre-render in&out in your sequence and then export.
