Issues with Premier Pro not syncing, audio, and video

[william_6735]

• I work as a local reporter at a TV station in Cheyenne Wyoming. I do on camera interviews every single day and have an external microphone attached to the video camera.
• I have never had this issue in the past but now every time I drag my interviews into the timeline of Premier Pro the audio and video are out of sync. The raw file is in sync on the desktop but as soon as I drag the file into premiere pro the audio and video are out of sync completely. Please help me find the solution to this problem.

Hi @william_6735,

Is this an AVCHD camcorder? Is it in .MTS format? If so, try the following:

1. Ensure you copy the entire folder structure to the computer hard drive before importing the footage into Premiere Pro.
2. Please import using the Media Browser and see if you get a better result.
3. How is playback? Let us know!

Thanks,
Kevin

Not a phone right?

What camera are you using?

Does it shoot constant frame rate?

What format is the video?

I have the same issue with audio not being synced to video for AVCHD file format. It started several months ago when these files were on the timeline on my MacBook Pro. The workaround was to use my PC. 

Today, I discovered the same issue with the PC (version 25 of Adobe Premiere Pro).

I tried converting it to an MP4 file using Media Encoder, but it still has issues.

Help!

This is a MTS file format, by the way. It works perfectly in the VLC player.

Using VLC, it is possible to convert to an MP4 format, which seems to work OK.

You might also try: https://www.shutterencoder.com/en/

It can convert to many formats and rewrap without encoding in some cases.

I am doing live stream on green K platform. I downloaded my VOD and I had audio sync issue during editing. I rewrap the video with shutterencoder and it fixed the issue.  Thanks

Well done! 🙂

I have the same problem, i have good quality audio files but premiere pro 2025 doesn´t sync an of them. It used to do the job on previous versions but not on the latest. might this be a bug?

Is there any update from Adobe? 

I had similar causal chain.
First *.mts-audio wasn't played in Adobe Premire Pro (v25.0.0) due to AC-3 is not supported in Win11 24H2 anymore. 
Installing AC-3 manually brings audio back in Premire Pro but reproducible not in synch ...

In case someone comes across this issue in 2025, directly importing the files from the SD card into Premiere solved the issue for me. Something with transferring them to my computer and/ external hard drive was screwing up the sync in Premiere.
