.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?

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.

Moved from the Creative Cloud to the Premiere Pro forum. They will be able to help you here.

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.

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,

  Perhaps we do have a poor workflow.  What we do works with every other piece of video software we've ever tried though, only Premiere Pro has this issue.  So  we don't know what is wrong with our workflow, and Premiere Pro is giving us no idea what is wrong.  PP just silently fails.

As far as impatience, we tell Premiere Pro to import something, and it shows up.  How long should we wait before we declare that the process is broken and sound is not going to show up?  Again, the software tells us nothing.

  It seems to me that the fundamental issues here is that there is no way for us to tell what is wrong.  Perhaps it is conforming.  I'd love to be able to tell PP, here is a directory full of videos.  Please go through whatever process you need to go through to be able to work with them, and let me know when that is done.  Is that possible?  If so, how?

The question of "how long should we wait," is shown by a progress bar, during the Conforming stage of the Import operation. When it disappears, then Conforming should be complete. This article goes into more detail: http://forums.adobe.com/message/4330843#4330843

As far as the workflow, exactly how are you handling the folders and files from your card? Are you Copying over the entire folder structure, or just the media files, themselves? Please give us the full details of how you are transfering the files from the card(s), to your HDD, as that will likely tell part of the story.

Good luck,

Hunt

Bill,

I had a similar problem yesterday where I imported about 30 short to longish clips (3 minutes to 30 minutes) and some of them had no audio.  I wasn't in a rush so I deleted all the clips from the project and re-imported them.  When I did this the conforming bar **never** started.  I thought it might be because the project "remembered" them somehow so I started a brand new project and imported the clips.  Still no audio in some of them and I'm positive all the clips actually have audio

I am *religious* about copying the entire folder structure (I drive my co-workers nuts about it) and I usually just import clips through Media Browser and walk away for awhile so the conform bar will finish.  What is particularly odd is that most of my work is long-format (1 hour+) and I never have this problem with long spanned clips.  I have had it a couple of times before and always with short clips.  It's never all the clips.  Just a random couple here and there.  Any ideas?

  As far as transfering files from the card, we've tried two things.  Just copying the .MTS files, and doing a copy paste of the entire directory structure.

  Premiere Pro does seem to do slightly better when we copy the entire structure.  However,  Premiere Pro still can't import the sound when using file-import.  If we use the media browser, it will import sound, but media browser only sees about half the files that are actually there!

  I've done quite a bit of googling on this, and this really appears to be a "glass jaw" issue for Premiere Pro.  Hopefully Adobe will figure this out some day.

  For now, the only thing that works for sure is to use a different program to convert to another video format.  That's working with a 100% success rate.

That's normal.  Often a clip will take up multiple files, due to the FAT32 limitations on the SD cards.  Media Browser shows you the first file from that group, but does properly bring in all the video.

So if a clip takes up file 05, 06 and 07, MB will only show you 05, then go on to 08.  That's because files 06 and 07 are actually part of clip 05.  So MB brings in all three as a single clip.

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.
