I have Premiere Pro CC My capture files are being imported as mp3 files. I have a macbook pro which I am having problems with and I have access to an IMac and the IMac with the same Premiere Pro CC software gives me zero problems. I'm not sure what else to change because simply changing the file name to mpeg or I saw online about an m2ts (I copied it right when I did it) file but that didn't work either. Any suggestions??
How and what are you "capturing"?
Using Apple converter cable with firewire from the camera to thunderbolt in the macbook pro. I am capturing HD video and can playback the timecode on premiere but they all come out MP3 files. Also, just for kicks I tried to capture it in IMovie and I had no problems there.
Please see this link for possible solutions:
Also, others have found success changing the mp3 files extension from .mp3 to .mpeg or m2ts.
