Though I don't have time to make more screengrabs today, I'd like to add an alternate method to try since it sounds urgent- this is what I recently used on a project where the audio was recorded at 30FPS and was supposed to sync with 24FPS footage (theoretically, this should work to sync any audio to any video that doesn't match perfectly to begin with):
- On a timeline, sync up your audio to your video at the beginning of the clip (choose the longest clip you can). Make the audio and video start at the same time (trim the heads of each clip).
Go to the end and find the latest sync point at the tail of the video and the audio. Trim the excess for both audio and video out. Now you should have two clips that don't sync, but have the in and out points synced.
Next, use the speed tool (sss on the keyboard, or look in the slip/slide tool tray). Use the speed tool to drag the outpoint for your audio to snap to the out point for your video. This changes the speed of your audio clip (in my case it ended up being about 100.10% - you can see this by hitting command-J). By locking in the two sync points at the head and tail, then adjusting the speed of the clip so both points sync at the start and end of the clip, you've got a good chance that you will now have sync.
Copy the newly-synced audio clip.
Then, throw all your audio files onto a new timeline, select all the clips on the timeline, and hit option-V. This will bring up the paste attributes dialogue, and in there you choose "audio speed". That changes all your audio to the slightly sped-up rate that you just copied from the fixed clip.
Select all the audio files on the timeline and throw them into their own new bin in the browser. From there, select all the new clips in the bin and do a batch export.
Bring the newly-exported files back into FCP.
The new audio files should sync up perfectly with Pluraleyes or manually.
At least this worked for me. Please let us know if any of this fixed your problem.
