MTS files out of sync

I have just re-opened a project I was working on last week. Suddenly all the MTS audio is out of sync.

I previously exported the timelines and they were in sync. I haven't changed anything in my configuration.

CC 2018 Mac OSX10.13.2

There have been numerous posts about this issue. When is it going to be corrected?

Try this:

1) Clearing media cache will NOT fix this issue fully. Some of you may have good luck, but not me on Win10 latest version.

2) Easiest and quickest workaround (after much too much research) is to:

a) open or re-install premiere pro CC2017 by launching CC app, using the down arrow and selecting "Other Versions" and choose cc2017 and wait for install. It will install pp2017 and media encoder 2017.

b) If you've been working in cc2018 and suddenly your files are out of sync, do not despair. From you CC2018 file, export to Final Cut Pro XML (File|Export|Final Cut Pro XML)

c) Open cc2017 and open this xml file. Check your sequences and they should be in sync.

NOTE: You'll probably loose all that new, cool functionality from cc2018, but hey, at least you don't have to go back re-cut ALL your work.

I hope this helps.

Actually, I did install FxFactory would that have caused it?

Installing FxFactory should have no effect. Have you tried clearing your media cache and letting Pr rebuild your conform (.cfa) and peak (.pek) files?

When you were able to export the timelines in sync, were you on Sierra, or have you been on High Sierra for this entire project? If it is a known issue then hopefully the next patch update will fix it.

Hi sequence W4,

sequence W4

I have just re-opened a project I was working on last week. Suddenly all the MTS audio is out of sync.

I agree with davidarbor, you may need to clean the media cache.

Thanks,

Kulpreet Singh

Has no affect on the audio/video AVCHD MTS out of sync problem....

I agree with davidarbor, you may need to clean the FAQ: How to clean media cache files? .

Just another voice with the same problem.  MTS files always worked fine in my projects before, now the audio is out of sync in them.  Happened for the first time about a month ago, but I had a deadline and just dealt with by manually syncing the audio for clips I was using.  Now coming up again in my current project. 

When I preview files outside of premiere, the audio is synced fine.  Inside of premiere it is off by a second or so.  MTS files with 59.54 fps, 12.1.1 (Build 10) on Windows 10.

Agree that this is a huge headache.

I know it's a pain, but I'd suggest exporting the files with the same pixel dimensions as prores422 and edit with those.  I know Premiere should be able to work directly with these files, but after trying to work with camera original in a number of different formats, if I have the time, I convert.  You should be able to use premiere export or adobe media encoder, but I use Editready which will automatically merge spanned clips if set up correctly.

This "known issue" is now going on 5 months.

THIS IS UNACCEPTABLE.

This new subscription model which treats everyone like a beta tester and test-dummy is beneath the dignity of any company that is seeking to be professional and to be responsive to their huge client base. Adobe rolls out updates which appears to be little more than beta releases and then seems to sit back and wait for the complaints to roll in...instead of doing it the right way and working through MAJOR BUGS likes this BEFORE the buying public has to be shipwrecked.

WHY IS THIS STILL EVEN AN ISSUE, ADOBE?

MTS files are a substantial source of media in our industry. I am losing time, money, work, and patience.

I have spent years singing the praises of Adobe and defending this company against the competition when it came to discussions with other fellow professionals, but now my trust has been shaken greatly.

Crickets.... interesting how there is no response from the mother cricket.

They do seem to love putting up Facebook live videos on subjects of how great Premiere is.

Still an issue V 12.11.
