Video with Audio Desyncs from Seperate Audio Track


so trying edit couple videos recorded of xbox commentary on it. video recorded @ 1080p @ data rate of 15001 kbps audio bitrate of 127 kbps (48khz). recorded voice on iphone , defaulted recording @ bit rate of 62kbps. can 2 tracks sync @ beginning, , both tracks sound if playing @ same speed. notice @ minute in tracks falling out of sync. @ end of video 30 seconds apart. looked @ properties of 2 files , noticed file durations far apart, though started , stopped them @ exact same time. , if synchronize audio @ beginning should stay synced end regardless of duration. switched premiere pro i've been doing exact same thing in powerdirector years , have never had issue. ideas?

one or both of media variable frame-rate ... vfr. prpro designed use constant frame-rate ... cfr.

 

you can find out yours downloading mediainfo, drag/drop media file onto program, go tree view, , see lists in video data section.

if you've got vfr, can download/install handbrake convert cfr use in prpro ...
