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.

Hi sequence w4,

Sorry for the frustration.

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

I see that we have a bug filed, however, if you (and others on the thread) could please file your feedback on the user voice site, it would help a lot in giving this bug more traction: .mts audio out of sync with video. Please fix. resume support for dolby files. – Adobe video & audio apps

"When" is not a question the support team can answer on the forums. Sorry; disappointing, I know. Engineering is doing the best they can in fixing this issue, however.

FWIW, I tested a couple of files and noted that the standalone .MTS file was out of sync on playback. The file that was brought into the project by first copying the entire PRIVATE folder to the media drive, and then importing via Media Browser was not out of sync.

Thanks,
Kevin

    Any solution with the  mts audio out of sync with video issue?
    I have edited and generated 20 mpg4 files based on the MTS before I discovered that the audio was out of sync. Very frustrating. I use version 2021 of premiere elements

    Hey guys in what instances did it get out of sync? I hope you guys import the entire PRIVATE folder in your working folder. Don't rename it etc just plonk in the entire folder inside your raw files folder etc. Cos my intern just did that mistake and I spent half a day trying to find a solution without realizing the private folder that came from source was missing.

      This appears to be the answer, don't know why it works but yeah, instead of dragging in the files, drag in the parent folder ("PRIVATE") and drag that into PrePro.

      Very confusing because the .MTS files play fine and in sync in m VLC player, but when dragged into PrePro in the "usual"way causes the audio to be about 12 frames behind the video.

      11 frames actually. Tested by importing the same file, but converted in different app. Panasonic AVCHD, 50i source (If it matters).

      Dragging the PRIVATE folder not working for me. Win 8.1, Premiere CC2019

        Here is my step-by-step with a little added editorial:

        Dolby Licensing, MTS / AVCHD Audio Sync, Premiere Pro CC 2018

        I hope it works for you...

        Same problem here. Version 12.1.1 Windows 10 pro.

        Unbelievable. I am working on a project for a client where mts files are used. What a nightmare.

          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.

            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.

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

              Thanks,

              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? .

              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.
