Video File Not Moving to Timeline

Hi Everyone,

I am having issues moving different files on to the timeline. When I create a project it takes the settings of the initial file and then does not let me move the other file (only the audio) to the timeline. I've looked all over for a resolution and the best I've seen so far is "change the file extension".

I have attached screenshots of the each file info. I realize they are diffeerent file extensions, frame rate, and resolution, but I was under the impression Pr could handle this and I could adjust scaling etc in the timeline.

If it helps, they are two angles of the same event that I want to switch between.

Any help with this would be greatly helpful.

Thank you,

Matt
