P: Audio of AVCHD files in .MTS format with PCM audio does not play correctly - sounds like noise

[kgroupcompanies]

[Subject line updated by moderator]

Using the latest version of PP (25.3.0) I was working on a project containing MTS video files, and all of a sudden the next day I opened up the project, and all of the audio tracks of the clips had max volume static (and nothing else). It had been working for several days. In the audio track timeline, it displays as just a solid bar, rather than a typical bar with variying levels as you'd expect (see attached). It is like this in the editor, and also if you export the video.

I messed with this for hours, including contacting Adobe Support Chat for about an hour. They weren't able to help. They left me with suggesting that I make sure all of my Windows updates were in place. I did that and still nothing. I messed with my video card drivers - making sure they were on the latest version, etc. I downloaded the AC3/AC4 codecs from the other Adobe post talking about MTS files not working in the latest version of Windows - that didn't help. I also have cleared cache several times, and I tried re-insatlling the latest version of PP.

If you open the files by themselves in Windows, they are fine. The audio is normal. They work fine in MS Clipchamp. They also work fine an older version of Premiere Pro that I downloaded (24.6.5). So, theoretically, I could start over and do this in 24.6.5, but I'd prefer to continue working in the latest version. I'm sure this is codec related or something, but I have hit a brick wall.

Has anyone else had this specific issue, and have you found a solution? Thanks

Any update to the mts sound issue?

[DarikD]

They were promising a fix in two weeks about a month ago.

Everyone affected by this should get a month refund on their CC for every month that goes by without fixing it.

This scared the living $hit out of me, Adobe.  Seriously, do better.  This is ridiculous.

[gavin_6927]

I'VE GOT A WORKAROUND. 

1) Download Goldwave (https://goldwave.com/release.php).

2) Drag-n-drop your AVCHD MTS file INTO Goldwave
3) Save it as a WAV

4) Replace the static in your Premier timeline.  

This really scared the $hit out of me today after a once-in-a-lifetime video deposition.  Not cool, Adobe.

Any non-Adobe transcoder will work. I used Handbrake to go to MP4.  All Adobe transcoders are affected right now. (If you have a copy of CS6 lurking on an old machine, it would work too.)

[ajay_khamkar5369]

I have the same issue. Recording on a Sony PXW z90 camcorder, editing on Premiere Pro 25.3.0. MTS files just have the scratchy static. Before it was just zero audio and now it's the noise. 

[MisterAdvent]

Yep, same problem.  Until they get it fixed, transcode to another format in any non-Adobe (or old Adobe) transcoder.

Why not just use an older version of the software?

Adobe Premiere aktardığım Avchd cihazlarının sesi cızırtılı geliyor. 
Standart bir oynatıcıda açtığımda sorun ortadan kalkıyor.

all MTs files imported to adobe premiere will have the audio destorted meanwhile it is very good on every other software , why ?

[Fergus H]

Hi all, 

This issue has now been fixed in the beta version of Premiere Pro and Media Encoder and the fix will be in the next released version of both applications. 

While we don't usually recommend using beta versions for production work, customers might consider using the beta version of Media Encoder to transode MTS files into another format (e.g., ProRes) which will then play correctly in the current version of Premiere Pro. 

Regards,

Fergus

Thank you

I don't understand why there's no answer to the question of why people with 50 terabyte archives in AVCHD and then .MTS files can't use Premiere 2025 because of an audio problem. I'm a customer and would like to know if you can fix this issue. There are thousands of dollars involve in this problem, I use Apple M3 Max . Premiere 2024 hasn't had any issues. I've asked several times to speak to a technician but still haven't gotten a response. Thanks.

There are hundreds of threads on this here, many on the facebook Premiere group pages, Reddit, elsewhere.

Where the problem is acknowledged and discussed in detail. I don't want to repeat what has been said many times ... 

[Antonio PAK]

 May be you not but someone else can help me, you know I'm a client! 

[R Neil Haugen]

And I'm also a user. There are others however, including staffers, who have already posted many details. Including as I recall some Mac specific things. 

While I'm real deep in color knowledge, the best help i can be for thus is suggesting searching this forum for mts problems.

@Antonio PAK 

Working in Premiere Pro 25.x or 24.x, I would use Shutter Encoder (donationware) to transode the MTS streams to ProRes 422 LT.  

[Antonio PAK]

Thanks I use Catalyst by Sony for Avchd,  is free. But intresting your proposal 

[robwilkenproductions]

First project in a while using MTS files from a client and all audio (which was recorded at a low level) are blown out when imported into PP25 newest version. They work like fine in Beta. I uninstalled 25 and went back to a 24 version and they work - allowing me to edit for now.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

It's a known issue, fixed in the beta version.

Hey Antonio,

The latest beta (Premiere Pro Beta 25.6) includes a fix for an issue similar to yours. Could you try it and let us know if it works for you? https://adobe.ly/3IOHZ6P

Thanks,

Ishan

Please tag me (@) in your replies so that it notifies me and helps me respond promptly.

[Antonio PAK]

Thank you Fergus ,

I will wait the next released becuase I dont know how to manage the Beta version. Please, Do you have an idea about the timing?

Grazie

Antonio 

[R Neil Haugen]

All users should check out the public beta version. We'd get better releases if they did!

You simply go to the Beta apps tab of the Creative Cloud desktop app, and select the Premiere Pro public beta, and install it like any other CC app.

It installs separately from the current release. And so can be used without causing problems.

[Antonio PAK]

The Premiere Pro Beta 25.0 it is Ok for the .MTS file , so now we have to wait ...ASAP...the upgrade by Adobe.

Thanks

AP
