P: .MTS video and audio not synched on Mac OS and Adobe 24

In short, there is a bug in Pr 24/25 that causes A/V clips with Dolby Digital playback out of sync.

The easiest fix for some time has been to install Pr 23.6.8 and edit in that version. The easiest way today if you need to complete the project asap is to install the beta version of Pr 25.2. They say that it is fixed but i have not tried it yet, ill wait for the release verison of 25.2.

Don´t ask me why it takes ages for Adobe to release a bug-fix for this issue... 

25.2 (Beta) is now availble if you'd like to try that.

For what its worth I would vote to have my $700 to fund bug-fix / quality activites rather than metoo generative AI features which don't impact my workflow in any useful way

it's been fixed in v25.2, but when will this be released? The newest version on my creative cloud only shows v25.1.

I'm so frustrated, I've been at a stand still all morning with this issue, when will this issue be resolved? Every video in import into v25.1 the video and audio is out of sync.

I have three 20 minute clips from a simple, single take, archive recording of a play.  I copied the files from my Canon XA15's SD chip to a hard drive.  When I play the clips in Media Player, the sound is correct on all three clips.  When I import (or drag and drop) the three clips to Pr, all clips are a bit out of sync (audio/video), but I suspect it's the working files that need to be rendered within Premiere.  HOWEVER, Clip 1 (20:00:30 long) has an issue when I play it on the Timeline or in the Monitor. At the 18:22 mark, the sound from the beginning of the clip replaces the originally recorded sound.  From that point on in the clip, the video continues correctly, but the sound starts over again from the very beginning of clip. The timeline plays through the transition to the next clip with no glitches and the sound seems to be ok throughout each of the other two clips. 

I extracted the audio in Pr from Clip 1 and imported it to Audition and the glitch is heard there, too.  To check that the disk drive version of the clip has not been corrupted, I can play it perfectly to the end on Media Player. I have also confirmed the health of the original clip by importing the disk drive version into Audition; no glitch is present.  To repeat, the other two clips of similar length (Clip2: 20:00:30, same length as Clip 1,  Clip 3: 19:08:00, slightly shorter) do not show any signs of this behavior.  I have also rendered the audio (Sequence>Render Audio) in Pr .  As expected the Timeline changed from Yellow to Green across the entire project as it should, synchronization of audio/video looks good, but the sound is still incorrect at the end of Clip 1.  So far there has been no processing within Pr. 

What could be going wrong and how can I fix it?

Nathan,

Which version/build of Premiere? As without that information, your post is pretty useless. In an earlier build, it was a problem for a number of users. In the newest, it should be fixed for most.

So if this is with an earlier build, it's not a big deal as it's expected. With the newest build, it would be useful information as that would not be expected.

Hi, almost all of my cameras use .mts files and Premiere has never had an issue with them until the 2025 version. Now every file I import, the sound is offset at the end with around 30 frames of silence, so everything is out of synch and has to be manually dragged back which is mighty frustrating. I just updated my premiere this morning to see if the next version up fixes it ( v25.1.0 Build 73 ) but no joy. Has anyone else hit this annoying problem?

Hi,

I have recently encountered an issue when updated to 25.0, when I preview some of the footage, the audio is delayed for about a second. Only clips at random are like this, the others are synced as normal. When dragged to the timeline, the audio delay is there and there a cut off about a second before the footage ends. Is this a bug from the new update? Tried looking online and haven't had much luck. This has never happened before and its quite frustrating having to sync up the audio on the specific clip I need to use, whereas the footage/audio on my camera is perfectly fine. Anyone that can help I would appreciate it. Thank you!!!!!!!!

(I'm on Windows 10 and using Premiere Pro 25.0)
