Hi all, long time lurker.

I have searched adobe forums and here. I have been fumbling with this problem for hours getting more and more frustrated.
Please help!!

I am trying to import AVCHD footage recorded on an Panny HMC 151 into Premiere Pro CS5. The problem, which I have encountered before, is that the audio on large clips is slightly behind the video. I know this occurs on macs from time to time but I am on a pc. I import the full file structure using the panasonic software supplied to my harddrive. The clips play with no problems in VLC player. I import the whole folder into Premiere using the media browser and not the file/import method. I have tried cleaning the media cache and forcing premiere to conform the clips on import but it still imports out of sync.
I understand that the issue is related to the FAT32 file system on sd cards that cannot make a file bigger than 4 gigs and thus I think it is an issue with how premiere nits the files together. I have searched in vain for the answer for sometime, perhaps I am using the wrong search terms.

I would be grateful for any suggestions or links to a solution,

Best Regards.
 
Hi thanks for the response, on the first attempt it was a DSLR sequence and I also imported via the file/import menu but since then, I have cleaned the cache and made a new sequence... in fact a new project. With the correct sequence settings. I am starting to suspect the cache is the problem though. I am using the 'clean cache button' in the edit/preferences/media path however, I have just navigated to the actual folder on the harddrive (its hidden, took me a while) but it is still full of files! I have now cleaned it manually and am waiting for premiere to conform footage. I will be able to try importing again and see if that makes a difference. Will post the result asap.
 
Okay, cleaning the cache and importing the complete folder structure seems to have solved the issue. I have always been careful to delete cached files at the start of a new project but it seems, for reasons I don't understand, using the edit/preferences/media 'clean' path does not actually remove all the cached data. I had encountered the audio sync problem before and importing the entire avchd folder via the media browser solved it, where as, conversely, the file/import method seems to cause the problem (even when you bring the whole folder in).

Okay, thanks to Richard for your help, lesson learned for me. I hope someone else gets the benefit of that one.
