.MTS files no sound

We use Premiere Pro to edit .MTS files. We have constantly experienced problems with Premiere Pro not importing sound. Usually, updating everything (not just Premiere Pro) will solve this. We currently have one machine were nothing is working, and right this second, we are deleting Premiere Pro to reinstall and try it again.

This nonsense of constantly battling to get Premiere Pro to import sound has been going on for months. Why is this such a horrible ongoing battle? Is there something we can do?

Correct answer jstrawn

There are some good suggestions on here, and I will add a reminder for people to use the Media Browser to import media (as opposed to the import dialog) with potentially folder-dependent formats like MTS.

By "folder-dependent" I mean the video may be in one directory and the audio may be a sidecar file in a separate directory. So if you're importing the video directly it may not see the audio. The media browser is smarter than the import dialog so it usually knows how to access and import the entirety of the media in a single import. MTS files are not always folder dependent (in fact in most of my own media, they're not) but they can be so it;s good to use the Media Browser when in doubt.... and that would go for most other formats as well.

Hello Fellow Premier Pro Users. I have found a simple fix to MTS files that all of sudden loose their audio. I spent three hours on the phone yesterday with Adobe Support and the individual could not figure out a fix. He recommend I create a "Watch Folder" and set the format to Quicktime and H.264. Then import the impacted clips into the project where the audio is missing. I actually never gave this a try because I found a much simpler method to handle this annoying problem. Please see below.

What I found extremely interestting was the original import from the video card had audio but the imported clips somehow lost their audio. This did not make any sense. Here is the successful pathway I discovered: Before taking the steps below, clear the media cache.

1) Copy from the original import from the video card the impacted clips, i.e., those that lost their audio. Copy both the MTS clip and the corresponding XMP file

2) Paste them into a different folder than the folder used for the orginal import of the clips prior to losing audio. I called this new folder "Changed MTS." In my sequence there were 24 clips that lost their audio which I copied.

3) Go back into Premier Pro, open the involved sequence, select the clips in the Project Folder that have lost their audio and then select "Link Media." The secret is to Link the involved clips with the new copies you created of each clip, i.e., I selected the clips I pasted into the folder "Changed MTS.

Guess what? It worked perfectly. These clips recovered the lost audio. Be aware....give them time to conform. Premier Pro sees the link as new media that needs to be conformed. Do no interupt this process.

Here is my thought on what happens when all of a sudden the MTS files lose audio. The original clip imported becomes corrupt for some unknown reason, Even if you link this corrupt clip with the original clip from the video card, it will not work. You must copy the impacted original clips and place them into a new folder and then link them. I believe this is successful because Premier sees them as a new clip and therefore goes through the conforming process.

A very simple fix to a problem that I spent hours with Adobe support tyring to fiqure out with no positive result. If you lose audio all of a sudden in your sequence involving MTS clips, just copy the impacted original clips from video card and place them into a new folder. Remember to include the XMP file. Link the clips in Premier Pro with the copied clips and allow the conforming process to complete. It took me exactly 5 minutes to handle 24 clips that lost audio in my sequence.

Hope this helps solve your problem with MTS clips with audio missing. Hope Adobe figures out why the clips become corrupt.

The easier, and perhaps better way, is to simply rename the folder you have the media in. Not the PRIVATE folder, but the one above that.

Combined with a cache clearing, this will force PP to see the media as new, and treat it as such. This has the advantage of not breaking the folder structure of the media, which can cause issues in some cases.

Hey Jim:

Thank you for the feedback. I assume you are referring to the folder which contains the imported files using Media Browser. I agree this would be simpler. Have not tried it to see if it works. If it does, please let the folks know at Adobe Premier Pro support about this easy fix. This will avoid a lot of hours being wasted trying to figure out a simple solution. Any thoughts on what causes these clips to loose their audio? Will Adobe have a fix to this issue in the near future? Thanks.

I tried Adobe Encoder, no audio. Tried VLC, keeps crashing. I found another forum recommend using Handbrake, so I tried.

Now, I use Handbrake. My only choice is MP4 there. On Presets pull out tab, I choose - Regular/Normal, so I get correct output dimension same as source. My video setting: H264; framerate same as source; constant framerate; 20,000 kbps; 2-pass encoding. Audio setting: Auto Passthru. It saves the file as an MP4.

Then I open it with Quicktime 7 and export to 422 HQ for editing in FCP 7.

If you only have Quicktime 10 that came with OS X latest versions, use it. Export to 1080p. You will get a usable H264 MOV like from DSLR.

I'm using Adobe Premiere Pro cs 6. Well, i was experiencing the same problem as you are. I don't know if this would work for you, but i just rename the extension of the files .MTS to .AVI and use Media Browser to locate the files and import them. The Adobe Premiere Pro CS 6 recognises both video and audio.

Remember, I just changed the extension .MTS to .AVI.

Let me know if it works for you.

Good Luck.

All I did was renamed all the files in Adobe Bridge using the batch rename feature under tools then reimported to premiere pro 2017 and it recognized the audio.

The two most common causes of a loss of Audio in MTS files is that the Conforming process was not allowed to complete - can result in no Audio, or truncated Audio, and not Copying the full folder structure (not just the media files), from the memory card.

If you have insured that Conforming HAS completed 100%, and have Copied the full folder structure, then something else is amiss.

Good luck,

How updating Premiere Pro (the most common fix we have) fix this?

For those two causes, it is not the program, that is faulting, but either a poor workflow, or impatience, that is the cause. If the cause is incomplete Conforming, then I would Delete the Assets, clean the Media Cache, and Reimport those Assets, allowing the Conforming to complete. If the cause is a lack of the full folder structure, then I would Copy that full folder structure to the HDD, from the card, Delete the Assets, clean the Media Cache and Reimport again.

Now, if neither of those suggestions fix things, perhaps the cause is something else, and could well be either program-specific, or Asset-specific.

The Uninstall/run the CS Cleaner several times, rebooting between each run/Reinstall is sort of a "last resort," though has been known to fix some issues.

Good luck,

Hunt

BTW, for people battling this, things that have worked for us include:

1) Update Premiere Pro.

if that fails...

2) Update every Adobe product.

if that fails...

3) Rename file from .mts to .m2ts

if that fails...

4) Uninstall all Adobe software, run creative suite cleaner, reinstall.

So far, one of the above has always worked. We do have one machine, that despite a full uninstall, running of creative suite cleaner, and full reinstall, can still only import sound if the file is renamed to .m2ts.

Come on Adobe, none of these should be needed. From reading the forums here and elsewhere, it is clear this has been a problem for over a year.

Thanks for these tips. On my very first use of PR CC I had the no audio problem. The clips were all self contained, ie. they were not folder dependent. I tried the simple rename of my .mts files to .m2ts and an .mp4 to .avi as I saw elsewhere searching, and all my sound appeared as expected. I'm really surprised by this because I would have expected this level of software to be able to import with little issue. I assume that simply swapping the container label opens up different processing, but honestly, I think it's a bit poor from Adobe to have to do 'hacks' like this.
