Sudden MTS File Issues

I have been editing MTS files (AVCHD) from a Panasonic GH2 (Some hacked some stock firmware) for over 2 years with little to no issues. I am using the CS5.5 Master Collection, Premiere Pro in this case, on a 3 year old Sager laptop (64-bit, i-7 720qm, 8GB RAM, 2 internal HDDs, nVidia GeForce GTX 285M). I am not sure if I am having hardware issues or a corrupt file but something is not right.
I am now in the middle of a project and all of the sudden my computer is VERY sluggish and it takes minutes before things update (such as scrolling in my timeline to a different frame) and sometimes it just freezes up all together. There is also an issue (could be related) with the second set of spanned clips (detailed below) from this project.
The timeline is DV 24P widescreen since it is going to DVD and also uses footage shot from a DVX100b for cutaways. The GH2 footage was all shot with stock firmware 1.1 at 24H, all shot on one day and the first recording time was just shy of an hour, then about 20 minutes and then another for about an hour. This produced 3 mts files for the first section, 1 solo file for the short section and 4 files for the last long section. I copied the whole card to my D drive without altering any of the folder structure like a good boy. I brought in the clips to the project window and had no issues with editing the first hour section. I will say that I did not use the media browser as I have learned recently is the preferred way to import these clips. For the last 2 years I have dragged and dropped using the windows explorer window and have not had any issues until now. I have dealt with spanned clips, a music video hat required over ten video tracks and much higher bit rates so I am not sure what the trigger is for these issues. What is odd about the second longer clip is that when the first clip is dragged in to the timeline( 00004), it only brings that clip, not the others that should be attached. The first section worked but not this one. And all of the files that follow this clip are numbered differently but look identical to (00004) when dragged to the timeline. They all appear normal in explorer (smaller clips that should be spanned together) so the footage is in tact, just not in PP.
I experimented a little and copied clip 0005 into it's own folder, dragged it in and it then displayed properly (not a copy of 00004). The sluggish issue is still there so I am not ready to just grin and bear it with this workaround. I also experimented by creating a brand new project, copying the original footage from my archive drive (never imported into a timeline so no xmp files) into a new folder and used media browser to bring in the footage. It didn't show clips 00005 and up since the media browser is only supposed to show the first of the spanned clips but it was still only 24 minutes long and obviously not including the rest of the clips. MEdia browser recognizes these clips are supposed to be together, but PP is seeing them all as copies of 00005.
I will greatly appreciate any opinions but bear in mind that I have used this same workflow on this same system for over 2 years. The only variable is that these spanned clips may be slightly longer than I have used in the past but not by much. I really don't know if there is a peice of hardware malfunctioning, if the clip is somehow corrupt or if I am missing something obvious.
What coulod cause this sudden change in performance? Would editing with a proxy help? Should I convert this trouble clip to a different format? Am I asking too much of my system? Are there ways to check if my computer is functioning properly?
Thanks in advance for any insight and for reading this rather lengthy explaination.

I wanted to give a quick update on this MTS file issue. I was able to get my system back to normal by isolating the trouble files in their own folders outside of the "Private" folder(the actual source files, not in the premiere project). I copied the first clip of the group into a folder by itself and the last 3 clips into another folder. I deleted the originals from premiere and imported (dragging and dropping from windows, not using media browser) the isolated files and they worked fine. Obviously they were now 4 independent files that I had to place side by side in the timeline but they lined up and there is no more lag in the system and there are no more duplicate files.
Far from conventional but it has me editing again and I didn't have to buy a new computer to be back in business. I can only guess that something glitched when it was conforming and it wouldn't recognize the spanned clips.
A special thanks to Eric at ADK for offering some suggestions that I fortunately didn't have to try.

MTS files (and really, they're just MTS, not the entire folder structure)..

OK, I see lotsa advice about dealing with MTS files...if they're in their proper folder structure.
Well, that'd be easy, and I'd be importing them now if they were in their proper folder structure. But they're not...I have 503 .mts files, in a folder, that a client copied "for me", and now expects me to import.
Any advice? Like I said, I only have the .mts files, not the supporting folder structure.

Greetings all from Jakarta - i have a feeling this is going to be a lengthy response and will only be of interest for those currently suffering from MTS file issues, but I do believe (while my solutions are not perfect) I have found some answers. What I have not found, unfortunately, are the hairs that I pulled out of my armpits in frustration over these MTS issues.
Background info: My office purchased the Panasonic HDC-TM700 to provide back-up to our Panasonic 170EN and we have been quite happy with the results. We have also been converting the MTS files to .MOV files on both Toast Titanium, and Final Cut Pro.
SITUATION #1
After a day of shooting I downloaded the TM700 files (full structure) to the hard disk. On day two after a full day of shooting I realized I forgot to format the camera's memory card so i had 50 MTS files that I already downloaded. Ever the smart guy, I highlighted file #51-#102 and dragged them into the STREAM file of the previous day's download. Then I formated the camera so i wouldnt forget the next day.
Well during log and transfer in FCP ONLY THE FIRST 50 FILES could be read, because that is what the metadata in the info supported ..... FCP couldnt even locate the other 50 files. I nearly fainted at the thought of getting fired. Thank goodness, when we dragged the MTS files into TOAST TITANIUM they could be read and converted!
SITUATION #2
The new guy (seriously, it was the new guy!) ONLY DOWNLOADED THE MTS files and since I wasn't there I wasn't there to see the havoc when neither FCP or TOAST could open the files. I was called in and my first idea was to take an old file structure, copy it, and slip the MTS files into the STREAM folder.
Well, it worked!! kind of.... The interesting thing is that the files could be converted in TOAST (FCP would not open the files) BUT ONLY TO THE TIME CODE THAT was equivalent to the original file. So if the original file was 1 minute and the file that I only had the MTS file for (and which corresponded to the file's number) was 5 minutes, only 1 minute was converted.)
So what I did was I took the TM700 and I shot five minutes of my foot. Then I downloaded the full file structure. Since I only took one shot of five minutes there was only one file in the STREAM folder, which was a 598mb file numbered 00000.MTS
I know I will regret it one day but i deleted the MTS file of my foot. Then I placed in one of the "homeless" MTS files into the (now empty) STREAM folder and changed the name to 0000.MTS -
When opened in FCP log and transfer - IT DID NOT WORK. However, in TOAST I am happy to say IT WORKED, yayyyy. And the file that was converted was the length of the clip. What I thought might happen is that if the clip was only 30 seconds long but the foster file was 5 minutes then there would be 30 seconds of footage and 4.5 minutes of black empty space on video. That wasn't the case.
THE SHORT TERM SOLUTION:
Over the years I have been very very very lucky with all the help I have gotten over the internet and in my own small way I hope the following helps out others. So here is what I have done, with instructions.
PLEASE NOTE I AM INDONESIAN LIVING IN INDONESIA SO WE USE PAL ..... 25 frames per second. .... Hopefully if someone in North America likes this idea and can help out, they will post a NTSC file structure.
OKAY INSTRUCTIONS:
1. Double click this link and download the file structure. The the file structure is only 68kb all your (and mine) frustrations for 68,000 bytes!!
www.klirkom.com/helpout/AVCHD
2. If you look inside the folder (AVCD->BDMV->STREAM) you will see AN EMPTY STREAM FOLDER. This is where you will place your "lost/not working" MTS files. Sorry, but this file structure only supports two files at a time. The first file is 5 minutes long, the second file is 33 minutes long (i was going to make it 10 minutes but I forgot about the camera being on and left it for 33 minutes ...)
3. Change your first file name (preferably an MTS file less than 600mb so that the 'foster' file can cover it) to 00000.MTS. Now change your second file (preferably less than 4GB, but unless you are filming the whole wedding this should be okay for most people.... the important thing to remember is that if you want your full file converted without missing any parts at the end, the files should be smaller in size than the foster files) to the name 00001.MTS
4. Now drag your newly named and newly placed MTS files into TOAST TITANIUM. Click convert. I have not tried this with other software but hopefully it works for you.
5. If you want you can now rename your original MTS files to their original names and continue with the next two files. I know with 500 MTS files this is a HUGE pain in the buttox .....
Okay, good luck all!!

FAQ: How do I troubleshoot audio issues when importing .MTS files?

Hello. The link FAQ: How do I troubleshoot audio issues when importing .MTS files?
does not work, and i need the answer please. My imported MTS clips are not playing back audio because it seems that no audio imported with the video. Thanks, Don.

Hi there
Audio plays when the object with the audio assigned appears. This is why you hear it when the Button appears.
Try assigning the audio instead to the object that appears when you click the button. Perhaps the caption.
Cheers... Rick

I am having issues suddenly exporting files. It reads error exporting 25 files, As I attempt to choose another destination folder the folders show a black square where the folder sign previously was. I am in my busy season and this has created a huge delay!!! HELP!!!!

oh and if you use a creative cloud version of Lightroom it could also be that the logon to the cloud is messed up. Logging out and logging back in from preferences in the creative cloud app will fix that. Due to the release of Lightroom CC it appears that adobe's servers have been overwhelmed a bit And many people have strange problems that are solved by logging out and back in.

HT5409 Can you turn this function off? I am having issues linking offline media(MTS files) in Adobe Premiere CS6

New imac with 10.8.4. With the new avchd coverter, I am not able to link offline MTS files in Adobe Premiere CS6. Any help would be greatly appreciated.

Adobe hasn't updated it's products to look inside the avchd packages.
You'll have to do it for them.
Right-Click on the avchd package (or whatever it is called). Choose Show Package Contents.
Keep digging into the internal packages in a similar way until you get to the folder with the mts files.
When you tell Adobe to open a file, just drag the mts file into the Open File dialog. If it cannot maintain that link, you might have to move the files to some other location Adobe can process.

.MTS File - Resolution Issue(s)

Greetings all --
Been awhile since I posted here, mostly because sadly I don't use this software all that often ... I am currently using Premiere Elements 10 on Windows 7 (useful for those who know more about the software than I do).
I have a 1 hour 45 minute or so .MTS file that was recorded at a resolution (frame size) of 1440 x 1080. (PE 10 recognizes the file format, so I first tried working with it without doing anything ...)
When I try to save it out to .AVI or save to a DVD, I end up at 740 x 480. This gives me a pixalated video. It's got lines through it, and when played on the TV I have a small frame inside a big black border. I would like to at least save it to 1080x(whatever the standard is), but can't seem to find a way to do so.
I tried using PE 10, I also tried using Nero 9 ...
Any thoughts? This is discouraging, to say the least. Thanks in advance for advice, suggestions, etc.
KM

A DVD is no larger than 720x480 http://forums.adobe.com/thread/544206
For larger, you need to create a BluRay... or export to a file for computer playback, or to a memory stick if your TV has a USB port and will play computer files

I am using MTS files. They load in PE fine. The problem is when I try to play them, I just get audio and no video. I have installed the latest updates. Is there a CODEX that I need.

I have windows 8.1. I have downloaded the mts files from my video camera onto my hard drive. I have loaded a subset of these mts files into premier elements and they show up fine. I can bring them to the time line without a problem. The issue is that when I click on them, I only get the audio and no video. Normally when you click a thumbnail, the picture shows in the large screen. That screen remains blank.

John - thanks for your response
1. Graphics Adapter: Nvidia GeForce GTX 650
2. My driver before you response was 3/4/14   9.18.13.3523. I went to Nvidia and downloaded and installed latest driver 7/2/14 9.18.13.4052
3. Rebooted and checked APE and no change in the problem. Still doesn't show video when I double click an thumbnail or if I single click it does not show a video image in the large screen.
4. Some things I have done to try to resolve the problem.
     a. Searched this forum for a similar problem. I didn't see one.
     b. Did a web search to see if I could find a solution outside this forum
     c Went into "edit" and tried some changes in project preferences and setting to see if that would make a difference
     d. Tried to contact Adobe support to speak to a person but that seemed difficult and could never figure out how to do it.
5. I have always loaded AVI clips into this program and this is the first time I have tried MTS files. When I opened the new project, the program notified that I had to change something??? to load an MTS file and asked me if I wanted the program to do this for me. I said yes and here I am.   I seem so close to making it work.   Thanks

.MTS File Metadata Workflow?

I have a client who needs to be able to search through a huge number of video clips via keywords in metadata but i've hit a huge wall when it comes to .mts files.
I am unable to write any metadata to these files, i'm seeing various reasons as to why this is the case, but no solution.
Spoke to three people at Adobe chat support this morning and no-one can help.
Is there any workflow in the Adobe Suite that allows metadata/keywords to be added to .mts files that can then be searched in Bridge or Lightroom for instance?
I have a keyword hierarchy produced that was intended to be used for tagging in Lightroom, I cannot assign the keywords to the original files but is it possible to create a Catalog that can then be handed over to the client with a copy of the video files so that they are searchable within the Lightroom software?
I have been trying to achieve anything similar in Prelude but still no success.
Am I the only one having this problem?

If you want to rewrap MTS files on Windows, without transcoding (like with Clipwrap), you can do that with FFMBC (for example). Yes, you can than reconect original files to rewrapped H264 MP4 and new Resolve will be able to read your timeline. However performance will be far from good.
Actually there is no perfect workflow for Premiere > Resolve roundtripping for MTS files at this moment:
- You can transcode everything to DNxHD or Prores before editing, but that's waste of time and disk space
- With combination of AE scripts you can transcode only material used in edit, but again that's waste of time, and you'll have to rebuild your timeline manualy
One option in Premiere Project Manager would solve all issues with roundtripping and that's "Create new trimmed project and TRANSCODE media with handles". That way you would be able to edit native, and transcode only media used in timeline.
At this moment your best option is to transcode everything before edit. On Windows use DNxHD, pick bitrate according to your source footage, and everything will be fine.

PP CC 2014 plays video fine from .mts files, but the audio is glitchy and jumpy.

Premiere Pro CC 2014
OSX 10.9.5
I have imported .MTS files from one Canon C100 into PP through the Media Browser. I kept the file structure intact from the camera when copying. When I play a file in the source or program monitor the video plays back perfectly; however, the audio is glitchy and jumpy. It will skip time, jumping forward and backward seemingly randomly. If I open the same clip in Quicktime 10, it plays back 100% normal. I have restarted, reimported, and even transcoded the files to Pro Res 422 using Media Encoder CC 14. Nothing fixed it. The audio glitches the same way in the transcoded Pro Res Files.
This is only the first of three cards of media. In total I have 120 .mts files in three separate AVCHD folders from a three camera C100 shoot. This leads to another issue I know I will run into. There will be three .mts files named "001," three named "002," etc. I have solved this issue in the past simply by transcoding, but that again failed to work for me thus far. So if I must stick with the .mts files, does anyone know a workflow for using multiple .mts files with the same name in one project/timeline?
Thanks

I find it hard to believe that this fixes the root of the problem as the same files playback fine in CS6. CS6 and CC 2014 should be referencing the same codec library on my system, right? If this is the case, then there is something wrong with how CC14 is decompressing the footage with the codecs that are working fine in CS6.
To further this point. I imported the same files into CS6. CS6 played them back fine, so I saved the session and opened it up in CC14. CC14 converted the project file and all media loaded and plays back normal now.
So if this is a codec issue, it would not have been solved by opening the files first in CS6. It also would not be solved as so many others report by moving the files and relinking to the new folder. It seems to me to be an import issue that is solely in CC14, not CC or CS6.

Using Adobe Media Encoder CS4 for MTS files

Hey everyone, I did some searching on this topic to no avail so here I am.
Anyway, I recently got an HD camcorder that records in 1080i AVCHD.
I have no problems getting the MTS files off of my camera but as I'm sure you can imagine, working with those files is a whole other issue.
I've found that Adobe Media Encoder CS4 works great in encoding these files to QuickTime format (.mov) but the problem is that the resulting file size is actually bigger than the original MTS file which is unacceptable, especially considering I'm encoding the files from 1920x1080 down to 1280x720.
Does anyone have any experience using AME CS4 to convert MTS files to a more workable 720p format for uploading to YouTube?
I've tried a number of different custom settings to no avail (where you see an "or" is where I've tried different options):
Format: QuickTime
Video Codec: MPEG4-Video or H.264
Quality: 100
Width: 1280
Height: 720
Frame Rate: 29.97 or 23.976
Field Type: Lower First or Upper First or Progressive
Aspect: Square Pixels (1.0)
I won't list the audio options because I don't think that has any bearing on my problem.
Any ideas as to why the encoded file sizes are actually larger than the MTS file sizes? Maybe AME CS4 is not what I should be using for this task?
Thanks for your help,
Tom

I figured it out.
If you select H.264 as the format you can then select YouTube Widescreen HD for the preset.
This will set everything up to convert your MTS file to 720p and reduce the file size by around 30% with little quality degradation in my experience so far.
The only problem I encountered was the video was kind of choppy when the camera panned but that was remedied by upping the frame rate from 24 to 29.97.
Hope this helps someone and if anyone has any suggestions to improve efficiency or reduce file size post it in here.

Encoder keeps crashing with camera MTS files during batch operation

I am trying to convert MTS files to WMV and I am constantly getting crashes.
"Microsoft WIndows: Close programs to prevent information loss... Your computer is low on memory...Adobe Media Encoder.exe"
and
"Adobe Media Encoder Debug Event: Adobe Media Encoder has encountered an error. [..\..\Src\Win\WinFile.cpp-785]"
I do have 8gb of memory with no other programs running and this is 1080/60 converted to 720/30 video and TaskManager shows I have memory to spare.
I have a lot of these and it's neccessary that I do a batch encode. The thing is that I can usualy encode the first item in the list but as the second one begins it crashes.
So it is possible for these files to be encoded successfully (the file plays fine) but the batch process is failing. It is not dependant on the specific file but just any file that isn't the first one in the list it seems.

I have also set my page file to go from 256mb MIN to 1024mb MAX because I have a SSD for Windows and i wanted to save space. I heard it was not neccessary if you have a lot of ram... I will have 16gb of ram again soon (as i just sent the other 8gb in for replacement). So maybe this could be an issue..?

Adobe Premiere CC2014 AVCHD mts files no sound restricted Dolby encoder - solution?

I wanted to import mts files from a Sony NEX VG10 Video camera. They are AVCHD files = .mts. This works perfect in premiere Pro CS6. Also in my school in Bruges with Premiere Pro CC version 7 something. But with premiere Pro CC2014 (school in Brussels) I can import the files perfectly for video, but the clips do no have sound. Premiere gives a fault message: Dolby audio decode licensing restricted.
On the forum people say that for CC2014 Adobe doesn't pay licensing to Dolby and this is the reason. But this looks nonsense to me. Suddenly making a program useless?
Of course I can rewrap the files... But then I can as well stay with FCP and would be very much better of with AVID. So.... who can tell me and give a solution to this problem.
Thank you.
Joost.

I forgot to say... We use mac.

.mts files out of sync audio when importing in Premiere Pro CC

When I import .mts files from my nxcam in Premiere Pro CC, the audio of the clips in not in sync. Can anybody help me with this issue? Thank you!

Hi,
Please try renaming one of the footages from .mts to .m2ts and then import in Premiere. See if that helps.

Problems started with 'Corrupted Project' and has led to 'Unsupported Compression Type" for certain .mts files

Had to revisit several projects that were working this past January, but now several are reporting as being 'corrupted'. After trying all of the usual recommended remedies, and failing, I attempted what is always my 'last resort' - Trashing Preferences. Last resort because it has always in recent versions, led to other problems. This time was no exception. Now, not only did trashing them NOT solve my corrupt project issue, but it added a couple more. Now, MB Looks plugin can't be seen, which has happened nearly every time I've trashed preferences, and certain .mts files are showing as being the dreaded 'Unsupported compression type', while many in the same folder are working just fine. This almost always seems to be a license issue of some sort. I have signed out of CC, then signed back in to no avail. My short term memory is nearly gone, but I seem to recall a similar set of occurrences a few months ago, and a uninstall/re-install was required to bring everything back to normal. This is getting quite old, as am I.

Working with Adobe Support via chat at the moment. Their solution? - Contact Red Giant.
