AME won't finish large export. Gets to 0:00 but left with unfinished files

[JBBrauer]

Hi,

I am trying to export a very large project, 7 hours of footage, minimal edits (title cards and clip transitions). AME takes 6-7 hours to export, gets to 0:00 time left, but doesn't finish, just sits there. In the folder there are the temporary files, the .acc and .m4v (? i forget the name of that one). On one attempt there was an additional mp4 file, but it wouldn't open and was 0 bytes in size.

Any suggestions to fix this problem?
Is my project just way to big?
Should I use different settings?

Let me know, thanks!

Here are my specs:

705 GB Free Space out of 1TB

Previously I tried these setting in AME:

Currently I am trying to export on these settings:
(note the difference in file size! 9.5 GB vs 49.3 GB^^ though the export takes almost as long..)
