Here is some other information on this issue...
https://youtu.be/CpaPu7RcW2c
This person says ths issue is... Powerdirector sets up the project at 30 FPS, yet the file I am inporting is coming in at 29.97fps. His solution is to set the projecyt to be 29.92, not 30fps and Bob's yer uncle... but PD15 doesn;t have that setting... the new box at work is getting Director Suite 365. Maybe it will allow this change.
Thoughts?

Jeff may have more/different info, but the 30/29.97 disparity doesn't quite add up. That's a difference of 0.1% (or 3.236 sec after 54 minutes) whereas the difference you're seeing is "only" 2 seconds.
..thanks... it is .. odd..
here is the tutorial I follwoed to fix my situation and shows a good example of the effect over a long file. Based on comments on the video, this situation is not isolated.... https://www.youtube.com/watch?v=F1tO_zx4LA8

Is the audio truly drifting to create a lip sync issue or just a different length? Independent audio recording is not tied to a video framerate so PD provides a option to move audio 1/10 of a frame for alignment as necessary, obviously 2 sec larger than that. Where applicable, a clapper often works good too.
If the raw audio is mp3, that often causes similar issues as you've noted. I often use a portable field recorder connect to the mixer board for stereo recording raw audio and I have to set my unit to wav as mp3 causes too many sync issues in PD.

Hi jeff...
I specifically avoid MP3 as I learned it doesn't like being edited and using uncompressed file for editing is silly anyway... . The Korg D3200 puts out a .wav file, That I then run through SoundForge to Master, and then back out to a .wav file and imported to Power/Audio director. The raw .wav file does the same thing as the edited and mastered, in that at the end of he 54 min run the edited sound is less than 2 sec behind video, so the per frame difference is really really tiny... stretching the file or choppign it up are both good solutions... but as the guy I work with said, he's never encountered the issue before...
...could it be the difference of 29.97 frames per second Vs a capture of 30fps? or rather.. if this is the case would it... just taking stabs at what it isn't...
Thanks for the activity on this thread.... now if I can just get the Blackmagic Decklink Mini card to work with the Powerdirector capture function..

I agree with JL_JL's approches if you're ok with stretching the audio. Another option might be to split the audio track after each song/act and resync it to the camera audio. That would evenly space out the gaps over the course of the 54 minutes, and you could simply extend the edge of one audio clip at each gap to keep the audio continuous.
Depending on whether you have any noticeable repeating sounds at each gap, you might want to overlap the audio clips a bit or move the gap a little forward or back.
Making smaller sections would certainly work and I considered it... but dagnabit...  the difference is so damn minuscule..
.. I work with a person that has been in broadcast TV for decades and has never had this issue come up,,, !

You are using a high power audio set up. Can the same be said for your computer. Out of sync is audio is sometimes caused by the computer/audio device not keeping up with the video.
What computer are you using. Do you have anything else running at the same time -- even background application like anti-virus, anti-spam etc. that you don't need to be running. Use Task Monitor to find what is running and start up manager to limit the number of programs that start when you turn off the computer (sorry if I'm suggesting somehting you already do).
From my searches for a solution and cause, I have found several YouTube videos that have this issue at the core and the solutions people use... it is always linked to tryign to put audio that has been recorded on a separate device from the camera inputs.
I've trimmed up the system . it is an i7 with 16gb ram and a 6gb nvidia card.. we only edit at 1080 at the highest... SSD main drive with spinners for some data (inherited it, but just built a new i9 box for the studio and am going to move the project there to see if it carries over. )
thanks

Usually just stretching audio not necessarily a good idea, if it works for you, then use it. In PD use the "Ctrl" key and just drag the arrow at the end of the audio clip and the length will be adjusted, i.e. speed change. If you prefer to set an exact length, the "Power Tools" > "Audio Speed" allows one to set a "Modified audio length" too.
Jeff
Agreed that stretching/shrinking is not a good idea, however we are talking a difference in timing of less than 2 secs over a 54 min video. it is stretching the entire file by .05847953%
What would be better, is to figure out why it gets out of sync?
Thanks for the in-program path to do this...

Good Day All,
A 54 min shoot of musical act ( producing a ongoing series this way) . 3 camera shoot switched on the fly to result in single vid file with scratch track from std board feeding audio to video capture. Separate 12 track audio recorder running at 16bit/48hz producing 54+ min audio track.
Import video and raw audio, line up beginning.... scroll to end... audio is out of sync, short by less than 2 secs over the 54 min run.
Was able to resolve using a competitors product by... import sound file from vid, import mixed down and mastered audio, line up beginning of files, scroll to end, enable "Stretch" feature, grab icon at the edge of file and stretch/shrink to fit, save as, import to Director and Bob resembles a your Uncle...
Why is this getting out of sync the way it is?
Is their a "stretch" tool in AudioDirector comparable to the one that I found in the mud hut program?
