AVCHD video doesn’t sound sync with video
Posted by Suzin Daly on January 19, 2025 at 7:19 pmI haven’t used my Panasonic 150…for yrs. I dropped the video onto PP 2025 for the first time, the video and sound were slightly out of sync. I fixed it by unlinking, and relinking once the sound was synced. I did a test and dropped the video into an old version PP C6 and snc was perfect. Out of curiosity, does anyone know what settings I can use to avoid this? (Please don’t say get a new camera.) I’m not doing a whole lot. Little I do, with DSLR. If there is a work around be nice to know.

Not sure what your specs are and what your sequence settings set at.
usually old school issues was the drop frame part.

January 29, 2025 at 11:56 amWhen importing a MTS video file into Adobe Premiere Pro 2024, the video track and audio track are not synchronized. I can see that the audio track is empty before the end (See attached jpg). When unlinking the video and audio tracks, cutting the audio track from the time there’s no more audio, deleting the empty part, and adjusting the speed/duration of the audio track to the duration of the video track, the problem seems to be solved. But if I have to do that for every imported MTS file in a project, that’s really boring, takes a lot of time. Is there not a way to fix this problem in preferences, or wherever in Premiere Pro?
This problem does not occur when importing MOV files, shot with my more recent camera. But I still have a lot of MTS video files I want to use for my new projects.
Can you please help?
Thanks in advance, Rob

January 29, 2025 at 12:18 pmHi,
I think the problem is that Premiere Pro doesn’t support AC3 audio codec anymore due to high licensing fees. And as MTS recording cameras aren’t very recent, there will be no support for it. One way to fix this is, not a short one, sorry, using the Media Encoder to convert these MTS files to mov before importing them into Premiere Pro.

January 30, 2025 at 8:37 pmI got that the file is no longer supported. There are work arounds. For what I’m doing these days, I still have PPC6…

January 31, 2025 at 3:10 pmHello again.
I tried to convert a rather large MTS file (3,99 Gb) in the Media Converter. That took a long time before the converter announced that it failed. As I chose to save the converted files in the same folder as the original file, I discovered a -even larger- MOV file (23,5 Gb) that has even bigger audio problems (many dropouts) and lasts only 4 minutes and 5 seconds…
So now just found another way to solve this problem; in Cyberlink Power Director (software I used before switching to Premiere Pro a few years ago) I uploaded the same MTS file, then saved only the sound as a WAV file. That went very quickly. Then imported the same MTS file into Premiere Pro, and the just produced WAV file as well. Unlinked le video and audio track of the MTS file, deleted the audio track. Then copied the WAV file under the MTS video track, and that works perfectly.
