Q: drifting audio with aiff file and video audio
Hello
i have some issues with drifing or not syncing audio in Final cut pro 7 Now I have read the Article from Matt Lyon but that does not fit my issue as I do not have an signes (the top green bar) that the audio has diffrent time rate also exported the XML file and everthing is the same with frame rate and audio rate. So here are the steps I did . I recorded a wedding dance on a Sony NXCAM Camera which records AVCHD files those files I then convert in Final cut pro to apple pro ress 422 files as the music audio is a bit soft I wanted to unterplay the soundtrack with the orignal music which was a mp3 files and that file I convert in Quicktime 7 to an aiff file matching the same audio rate then the video 48Hz 16 bit Now when I put the aiff file on the timeline and sync them up in the begining of the song after just a few frames the audio is alrady out of sync it seems that the audio from the video is faster then the aiff file but both sound ok .
tried drop frame or non drop frame but nothing happens tried matt lyon options but it is the same even tried to edit in Premiere and there is the same issue
anybody has some idea what could be the problem as someone asked me to shoot a music video and if that is the case i might ave serious issue after the shoot
thanks

I believe your problem is that the player that was used to play the music at the event you shot was not playing the audio at the correct speed.
One solution is to place your new imported audio file on the timeline and sync it at the head of the camera recorded audio. Then control-click on the audio clip you imported and adjust the speed of the clip until the duration and waveform of the file you imported matches at both the begriming and end of the song.
It may take a bt of trial and error to find the matching speed.
