Hi guys,
I'm editing in premiere, and are working with mpegs. These files were originally .MOD, but the only way I was able to get them to work on my PC was to change their file extension manually to mpeg. (It is impossible on the PC i'm using to install any converting software etc, and they do not open in any adobe product)

I'm putting them through After Effects to scale them up to 1920, as they weren't shot in that, and I need to match them with some other footage I have.

When I export from After Effects in whatever format, the video will only play for 1 second and then freeze, but the audio will keep going. Even after I render the timeline.

What should I export my mpegs as from After Effects, and what should my sequence settings be?
