My video is exporting as a M4V and AAC instead of a MP4

For some reason, the video I want to export as a MP4 became a M4V and AAC file. I do not know why this is randomly happening now, any help would be appreshiated.

These are the two "streams" of your file before they get "muxed" together. MP4 is a container which holds the video (M4V) and audio (AAC) and treats them as a single file. If you're not seeing the MP4 then that means your encoding isn't finished or it's failing. What happens in Premiere after the encoding hits 100% and the dialog box goes away? If you send you sequence to Adobe Media Encoder do you see the same thing?

As soon as it is finished exporting Adobe Premiere Pro closes (this is also a new thing thats happening to me) and those 2 files stay on my desktop. The problum seems to be it doesnt merge them because Premiere closes itsself for some reason.

It sounds like Premiere is crashing then at the end of your export. What exact version of Premiere are you using (not just the year, but the version from Help > About Adobe Premiere?

Are there any updates? 

Have you tried uninstalling and removing your preferences before reinstalling and exporting again?

I have tried uninstalling all of Premiere and the preferences and reinstalling Premiere, I am using Version 22.0.0 (Build 169). There are no updates available. I apologize for the late reply, I had to get myself to my class.

I would try a few things:

1) See what happens when you queue the export to Adobe Media Encoder, rather than exporting straight out of Premiere. Either way, Premiere shouldn't be crashing, but this can help narrow some things down.

2) Create a new Premiere project and import your existing one in, then try exporting again.

3) Lastly, does this happen with all H.264 exports or just ones from this specific video file?

I have tried other exports other then H.264. The MOV file also currupted. After clearing my cache I was able to export it as a 720P MP4, but 1080P still crashed for some reason... I hope this is a unique problum but if it happens again I can come back to this form for refrence. Thank you so so much for offering your help.
