.mts

[Louella Kammann]

Weuse 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.

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 ent

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.

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.

You wrote "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."

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.

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:

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.

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?

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!

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.

ok why has no one mention VLC media player??????? I converted my MTS files using this and it worked! Dont worry about re installing and all the other garbage coz I have tried it all. Use VLC and all good

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.

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.

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.

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.

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.

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.

A great solution. Although, if you have cleaned your memory card with the original files (for re-copying from XMP, who forgot to do it from the very first time, and there are a lot of such here), then you will have to think about another way to solve the sound restoration problem. Adobe should solve this problem with sound loss.

I've run into this problem with locked audio tracks. When audio tracks are locked, the video appers to import without it's associated linked audio. Unlocking the audio tracks remedies the problem - as shown in this screen cast: -o-matic.com/watch/c2VYYjn1RF.

I have a bunch of mts recordings from my Sony Handycam. Now I want to import them to my Mac and then put them into iMovie for further editing. How do I do? I heard that mts should be converted to mov format which maintains high quality but compatibale with iMovie and Quicktime. Is there any freeware to convert *.mts files to mov? Thanks for any recommendations.
