Can anyone prove that this is a program bug? It certainly gave me big problems in editing my show. Don 

Can anyone determine if this is a program bug? It gave me a great deal of difficulty editing this one hour show. Don 

I have found a work-around for the problem mentioned in the previous post. If I split the video track after each area where I muted the audio, there is no problem. Don 

Studio has really been giving me a problem with my present project. After much time I think I've figured out the procedure that causes the problem. My project is one hour in length and consists of a video track, Sony HD camera, AVCHD and the file is .mts. Two audio tracks each .wav. I have completely uninstalled and re-installed studio 16, ...

After spending considerable time trying to sync the files in PS 16 without success, I put the files into Adobe Audio Audition and adjusted the speed there. I then put them back into PS and they stay in sync from beginning to end, one hour. jjn, thanks for your assistance in this matter. From my experimenting, it appeared that PS couldn't handle ...

I continued testing the problem while changing the length of the files. I trimmed the project to 45 minutes and there was no problem. I then trimmed it to 59 minutes and the problem returned. I have attached a screen shot of the speed panel. 

Your're correct, since I could only put one screen shot, I put the one without the speed effect. If the speed effect isn't on the wav file, there is no problem syncing the begining of the file. When the effect is applied, the time line doesn't shift, but the audio itself is delayed and no longer in sync. I'm sure you know what is a recorder, it's ...

I now have additional information. I trimmed all the tracks so that they all begin at the beginning of the timeline. All are in sync at the start, and remain in sync as I play. Because of the accordion track recorder running slightly off speed, I have to shorten that track a couple of seconds in order o have sync at the end of the one hour ...

The audio format is .wav. The files are in sync at the beginning of the timeline. I zoom in on the time line to the frame level, then zoom out to full time line, now the audio track is out of sync, delayed about 1/2 second. Don
