Why doesnt premiere pro save my videos as MP4

[vevegirl23]

Good afternoon Adobe Support Community, so recently when I saved a video file in premiere pro onto my computer to upload to my YouTube Channel, I noticed that the video file had saved as a MPV file and not a MP4 file and I have no idea why this is happening but its really frustrating, I just want my videos to save as MP4s files so if anyone knows how to fix it please tell me by commenting down below

Thanks so much in advance!

Post screenshot export settings.

Did you try it again, checking closely your export settings, or perhaps you let your frustration get the best of you?

LOL on letting my frustration get the best of me I laughed at that thanks for making my day btw

Anyways, I have tried to do it multiple times and I did check my export settings here's a 1quick screen recording of me checking all the settings in export

Your screenshot says mp4.

General settings look ok, but you do have an odd sequence settings which you are trying to scale up to HD. Hence, the black bars all around.

So should I not scale my video up that high? @Ann Bens will that make it an MP4 file if I fix that then?

[Ann Bens]

Upscaling is not ideaal.

Might want to export to 720p.

You can try multiple exports. If your exports go quickly, then use the sequence, but you can also set in/out points and just export that bit while you are testing.

Thank you @MyerPj it worked and uploaded perfectly! I just have to remember not to go up so high with the video quality thank you so much and you made my day yesterday when you said "or let your frustration get the best of you" that was funny!
