Premiere Pro CC and missing audio tracks for .mts files

Its a Easy Fix

After Updating to the latest version adobe Premier Pro CC

There are some changed that take place in your setting.

The media cache location goes to default location so the cache goes missing.

I had set my cache location to SSD : Z drive but after update that all changed to User/ Appdata / roaming / adobe / media cache.

so here is where Premier gets confused and does not reconstruct the cache files cause it looking for the original cache location.

The FIX

delete all the cache files in default location and also cache in folder that you created for cache all media.

Then in the preferences/media set up the new cache location.

now open your project in Premier

It should automatically start rebuilding your cache and

the .MTS file should now show audio wave.

No Need For Uninstall its just a bug. but a easy 10min fix.

I don't know if this helps but I've been having problems with mp4 files, audio missing when I import. when I first open a file it is empty before it makes a sequence. For some reason when I drag a file over when premiere is in this state it sees the audio. So I import all the files I want to use from the media browser, then I select all the mp4 files I want to use and drag it over to the sequence window and it sees the audio. I'm using Windows 8.1. I've never hand this problem before but this the workaround I'm using. Also it works when you copy the sequence, it copies the audio too. This sucks to have to work like this, I'm paying way to much money to have to work like this. Please adobe fix this problem for windows. Thank goodness I'm not doing anything to complex or I would loose my mind.

what i just ended up doing was, i imported the Video CLip into Adobe Audition and then exported the wav to place into Premiere, worked.

I'm having the same problem here. I have a Macbook Pro and I'm  running adobe CC latest. After renaming some of my mp4 files, and I had to relink them, the audio track did not show on the timeline at all. Even when I play the file from the media browser, it shows the video but the sound does not working at all. This is a big problem because I have a lot of video projects that are affected by this. It would take a lot of time to do the workarounds.

This is terrible. I can't believe it's been two years since people complained here and this issue still has not been resolved.

Thinking to unsubscribe from Adobe.

Where is "Delete audio cache files"...???  Mine only shows "Clean"

I had the same disappearing audio and repeating audio. If you delete the audio cache files (.pek) then it will force a new audio conform and then work fine.

Moving from FCP to Adobe not long ago and this happened twice. I've tried to revert it back to previous version but it just can't overwrite my current version. Tired up of switching back to FCP everytime...I'm now converting my AVCHD/MTS after reading this mts to mpg article, but still hope Adobe could fix it so I no longer need spend hrs to do the conversion.

FYI I had the same problem...

Everything was fine then I tried to add a gopro file .mp4 into my project and all of a sudden it wouldn't import any audio (mp4 or mts)

The workaround I found was to edit the clip in Audition  from the project files when I did this it created an audio clip i then linked to the video part of the mp4 file.

Hope this helps!

I've been having this .MTS audio problem for a while know, and have read a lot of posts about different issues and ways to handle them. Here is a short overview of my experience the last few weeks, but this issue has been bugging me more and more after I started producing a weekly TV show with lots of .MTS files from my Canon C100.

• I've had missing audio, looping audio and even audio from older files with the same file name, i.e. "00127.MTS" has shown the right video, but played an audio from a file with the same name recorded some weeks earlier (the two files are in different folders on my Media Drive of course).
• I've cleaned the Cache files: Common/Media Cache, force quit the processes aerendercore and PProHeadless, to be able to empty the trash.
• I've restarted PrPro, the program has rebuild the Cache...but sometimes that hasn't solved the problem.
• My recent "brute force workaround" is to manually find the Cache file in the Commons folder, i.e. by searching for "000127". That gives me results like the following: "00127-6c2....ims" - "00127.MTS 48000_1.cfa" - "00127.MTS 48000_1.pek"). I delete those files, offline the clip (00127.MTS) in the project, relink it - and this usually solves the issue. But it's getting more and more time consuming to do this with more and more files.

Could this be a problem with PrPro linking to the right audio files? This could explain why I've been getting audio from older .MTS files with the same name.

If this is the case, I find it strange that the program doesn't have any problem linking to the right video files all the time, but seems to screw up linking to the right audio files.

I hope Adobe can shed a light on this annoying bug, that seems to have been causing a lot of people problems for some time.

Mac OS X 10.8.5

PrPro CC 2014 8.2.0 (Build 65)

Same problem. Audio waveforms are gone on a project where they were just at 10 minutes ago. I think it happened because premiere was conforming files when i did a save.

Found a 30 second fix.

Go to the folder containing your original media. Rename it to anything at all.
Go back to premiere where it will immediately say all files are offline.
Go back to the folder and undo/rename the folder back to its original name.

Return to premiere once more and locate one of the offline files. It will reconnect all files and your audio will reappear.
