.MTS file has no audio- Premiere CC 2018 and CC 2017

I had to download a third party tool to get the Dolby codec for Windows 7.  I just want to say that it is shameful and abysmal that Adobe, even in CC 2019, does not properly support MTS files!

This is a very annoying problem that Adobe needs to fix.  The one workaround that has worked for me is to import the mts file to the project as usual.  Then right-click the file and choose "New sequence from clip".  The audio appears in the new sequence along with the videa, and the clip can then be moved/edited as desired.  Hope this works for others, but please Adobe, fix this.

I have the new Premiere update and using Windows 10 1804.

I have a round-about way to band-aid this, if you have a copy of Sony Vegas . (oh God will I get banned for mentioning this NLE here?)

The problem occurs, for me as I used Sony cameras for many years and had file types like ,mpg, .Mts, .m2ts.

When CC came out I noticed that my old mpg files from a little Sony DVD 305 no longer imported. That== or it just didnt work anymore for other reasons.

The 1440x1080 60i AVCHD files like Mts and m2ts still worked in CS6, CC and 2017 CC until this last update. I learned here that there was beef with Adobe and Dolby. So no sound for my files anymore.

I tired handbrake but the m4v files would not import to Premeire.

I tried a slew of converters,

Adobe Media Encoder

even Cineform, no worky.

I had to think back that Sony and Dolby were buddies.

What FINALLY worked was opening Sony Vegas with a plugin called Vegasaur's Transcoder. Dragged all of the files from my archived project that were showing as "red media missing" Many of these had 5.1 sound.

I was able to batch render or transcode all of my project's m2ts and mts files to mxf files. The program lets you keep the name of the file so you can replace footage or link footage in the Premiere media locator. There is a preset for nearly everything.

Well, after much googling I had to accept that there were really no proper solutions to my problem. Adobe have apparently admitted in a statement a while ago that they were forced to withdraw Dolby support from Premiere and the only "solutions" were to either upgrade OS, roll back PP to 2017 with Windows Restore (not an option for me since I never created a restore point) or convert all your video files with a third party utility.

My own personal solution, which isn't ideal but it's the quickest and easiest in my case, is as follows (also shared on another post):

Load the clips (MTS in my case) into Avidemux (free), leave the Video option as "Copy" (for quick and lossless conversion) and change the Audio to a different format. I chose MP3 but there are many others which Premiere will happily work with.

Then change the output format to MKV and save. Do this for all clips in your project folder, it doesn't take long at all (a 40 minute, 1.9 GB MTS file takes about a minute to convert on my machine). Then move or delete the original MTS clips from the project folder.

Next time you open the project in PP 2018, it will prompt you to locate the missing files. Assign each missing MTS file to the newly created MKV version and you're done. Sound is back on and your projects need no modification.

Now I can keep both Windows 7 and PP 2018. It's an extra step to perform each time I import from my camera, but I mainly work with a few long clips so it's not too bad. For people who work with several short clips, it might be too time consuming, so maybe a utility that converts in bulk is better for them. Avidemux doesn't seem to offer this option, although batch processing is apparently possible with a script:

Still hoping for a fix from Adobe, but it seems unlikely.

Same problem here, I just updated from CC 2017 to CC 2018 and now none of my MTS videos have sound.

NO SOLUTION SUGGESTED ANYWHERE WORKS. I tried:

- Clearing media cache

- Renaming Common folder.

- Renaming from MTS to M2TS.

My MTS files are coming from my Canon XA10 camera and always worked fine on previous Premiere versions, I am now convinced (having read several posts on the subject) that this issue is to do with Adobe having removed support for the Dolby audio coded used by Canon. But if that's the case, WHY WON'T THEY TELL US SO, instead of having people running round in circles? And maybe provide an ACTUAL SOLUTION? Now I don't even know how to downgrade (is it even possible?) so I have hundreds of unusable project files containing clips with no sound.

Anyone have any more ideas? The suggestion in the YouTube video didn't work for me, the "last step" mentioned at 2:20 about source patching can't even be performed, I have no A1 toggle to click on.

It seems Premiere is simply not recognising MTS as an audio and video format, it keeps saying MTS media from previous projects is "Offline" and newly imported MTS just has no audio track at all. Importing from the Media Browser makes no difference.

Can anyone shed any more light on this?

Here is the real solution: NO SOUND In Premiere CC 2018 - Fixed QUICKLY - Thanks GOD - premiere not importing audio - YouTube

Quit Premiere. Rename the adobe/Common directory in your library. Premiere will build a new common directory. Works on Mac too. We just tested this out.

Clean out media cache as shown below:

FAQ: How to clean media cache files |Adobe Community

Rename top folder footage is in or copy/paste footage to different location and try again.

For dolby you need 2017.1.2 (note that the latest download version is 2017.1.4 which had not dolby anymore) or 2018.0.
