I've been using Premiere Pro for a couple of years now but have only just tried to use multiple cameras.
As I didn't think to set the cameras to the same settings before filming I've got the following...
- GoPro footage at 25fps with audio at 48k
- iPhone footage at 29.97fps with audio at 44.1k
How do I go about adjust one or both to work together? ...I've tried setting the iPhone fottage to 25fps via Modify/Interpret Image but once it's processed it seems to be way longer than the GoPro footage.
I'd like to get the audio in sync so I can line up the footage accurately (although I will be importing separate audio from a portable recording device).
If the iphone has variable framerate you need to convert to constant framerate before bringing it into Premiere, otherwise you will never get the audio correct. Might sound correct on the timeline but once exported its most likely out of sync.
You cannot transcode with AME as it selects the wrong framerate.
