AVCHD/MTS Editing Issues in Premiere 2014

Greetings, folks.  I am a newbie to this forum and to Premiere in general.
Background
I have a ton of .MTS files I have pulled off my Sony HDR-CX700 over the years and are now stored on hard drives, without any of the other associated files.  In searching through this forum, as well as others, it seems that these files are supposed to stay together, as Premiere and other programs look for additional files as part of the AVCHD "wrapper."  These files do play in VLC with sound and I do seem to be able to import them into Premiere.  However, they don't seem to be able to be played or edited in any fashion.
I have attempted to convert them via Media Encoder (using various presets for YouTube, H.264, DNxHD), but that has merely yielded files that show the same behavior in Premiere.  Specifically, I can see the file and it looks valid, but doesn't appear editable.  I have heard some folks mention ClipWrap as a fix-all for this type of situation, but it seems crazy that there's not some solution already included as part of the CC suite.  I am using CC 2014 version of both products.
Question
How can I get my .MTS files into a format that I can edit or what I am doing wrong in Premiere that is limiting my ability to edit them?  Again, I don't have the option of copying the file folders over again, since, for the vast majority of them are gone forever.  I just have .MTS files that play perfectly in VLC.
Any help or insight would be appreciated.  Thank you!

Hi,
Please try this small step for one of the files. Change the extension of the file from '.MTS' to '.M2TS' and then import in Premiere.
I hope that works for you. Let me know the outcome.
Regards

  • Projects settings for AVCHD MTS files in Adobe Premiere Elements 8

    Hello,
    I have read several discussions already, about importing AVCHD MTS file in Adobe Elements (version 8), but I'm also confused a littlebit, so I would like to confirm if I'm correct.
    FYI, I have a Canon Legria HFR26 camera and am using Adobe Premiere Elements 8 (with the latest updates installed).
    According to the specs in the Canon instruction manual:
    Videos are recorded in high definition using AVCHD specifications
    (MPEG-4/H.264 compression).
    Audio compression: Dolby Digital 2ch
    The camera supports making video's in different format, but I have done it in the default SP format, which results in a resolution of 1440x1080 (50 fields per second, interlaced).
    I have copied the video from the camera to my harddisk, and Windows also mentions the video's as AVCHD of 1440x1080 (Bitrate 7672kbps).
    The frame rate is 25 frames/second. I assume this is correct for 50i?
    So, when I import my video's into Adobe Elements 8, I select the following projects settings:
    PAL, AVCHD, HD 1080i 25
    Because the description matches my video files:
    - For editing with 1440x1080i AVCHD camcorders.
    - 16:9 interlaced HD video at 25 frames per second.
    - 48kHz audio.
    The video's are imported correctly and I can play them. However, as soon as I drop a video on the timeline, Adobe immediately starts background rendering the video (a red line appears on the timeline).
    What I understand from some discussions, is that this shouldn't happen, because the video format doesn't match the project settings. On the other hand, I have also read that for Adobe Elements 8 this is normal behaviour and it always start background rendering AVCHD video's.
    Is this expected behaviour or should I chance my projects settings or maybe even convert my video files to a different format?
    Thanks,
    Michiel

    The ability to work natively with AVCHD files was not added until version 10, Michiel. So you'll still have to render while you work in version 8.

  • Editing .MP4 in Premiere 2014 CC out of sync - XA25 clips

    Hi there,
    Constant problem I am having, I record in .MP4 in XA25 of someone speaking to camera wearing a Sanken COS-11D lavalier microphone.  I then transfer the file to my computer and import the file into Premiere and the voice doesn't match with the video.  Seems a few frames out.  I suppose I can adjust the audio layer to match the video, but that won't work for a long term solution. Any suggestions?
    thanks!

    Hi Kevin,
    I don't see anywhere in the user manual that says it is variable...
    Here are my settings for recording with the XA25
    MP4 - 25p @ 24Mbps
    I am going to try it in AVCHD and see if I get the same issues,
    Maybe I need to pick a codec that matches better for editing?
    cheers

  • AVCHD (MTS) video files thumbnails previews

    Hello,
    How can I have video thumbnail previews for my AVCHD (Mts) video files in Premiere, After Effects?
    I can preview alla the other formats but not the above one.
    Thank you.

    cdlansford
    Hunt is correct in that the video codec AVCHD (MPEG4 AVC/H.264) was not supported by Premiere Elements until version  7. A variety of converters were used in those days before Premiere Elements 7 (because of AVCHD non support) and after versions 7 - 9 because of the resource demands of the AVCHD editing in those programs.
    Typically the converters in those days took the AVCHD to a MPEG2 HD.mpg form. The most popular one at the time was the free Koyote Soft HD converter. You may want to check it out and determine if it would work for you.
    http://www.koyotesoft.com/video-software/free-hd-converter.html
    As I recall there were a lucky few at the time who had Sony Vaio computers which offered an add on for AVCHD support in Premiere Elements 4 running on a particular Sony Vaio computer.
    Any questions, please do not hesitate to ask.
    Thanks.

  • A conclusion to ALL the AVCHD/.mts Log and Transfer Final Cut Pro 7 issues

    Hey all! Happy 2011!
    So this is my first post here and hopefully when this thread concludes with all your help we should be able to help a lot of people and save them the heartache that I have recently had to endure by stating these things in plain English. I have some questions at the end which I think could be answered very easily! Please, no gobbledygook!
    It would be great if people in the know can confirm/deny or comment on my points so those that are in a similar position to me can save their time and just get on with it.
    1) I have a Panasonic HDC-TM300 and it records in AVCHD/.mts files
    2) FCP 7 can deal with AVCHD files via the Log and Transfer feature if you do it straight from the camera or memory card and can convert to ProRes 422 (LT)?
    3) Log and Transfer _*DOES NOT WORK*_ if you move the AVCHD/.mts to an external drive without maintaining the folder structure?
    4) What is required from the folder structure that makes FCP act this way?
    5) Basically I have f*ed it by doing the part 3 above which I think is the most natural thing in the world to do! Im sure that many people have done the same thing as me please correct me if i’m wrong
    After a lot of research on the internet I have come up with the following solutions and in brackets my thoughts on them. If anyone has any experience with them please please let me and other people know so I can get on with my life and editing these files.
    a) Harass the people that make FCP 7.0 and make sure that the next update solves this stupid/idiotic/ridiculous oversight. (This could take a while but i think we should do it for the sake of future generations)
    b) Someone could let us know about a workaround to this that may be the folder structure that FCP needs to be able to do L&T (needs to be simple so that everyone can do it. This would be the best short term solution until part a is completed)
    c) Buy one of the converter programs such as ClipWrap, Toast Titanium or Aunsoft mts converter. If so which is the most/ least recommended and why? (Least desirable option due to requirement for extra program so extra faffing and extra cost).
    Thanks y’all and keep up the awesome work!!
    K*

    2) FCP 7 can deal with AVCHD files via the Log and Transfer feature if you do it straight from the camera or memory card and can convert to ProRes 422 (LT)?
    Yes.
    3) Log and Transfer DOES NOT WORK if you move the AVCHD/.mts to an external drive without maintaining the folder structure?
    This is true of ANY tapeless format.
    4) What is required from the folder structure that makes FCP act this way?
    This is due to the fact that most of them have files in those other folders in that structure that FCP needs to access in order to get all the proper components assembled properly. Sure, there are formats that have folders with nothing in them. Doesn't matter, FCP is designed to look at the full structure and work from that.
    5) Basically I have f*ed it by doing the part 3 above which I think is the most natural thing in the world to do!
    The most natural thing in the world is to NOT backup everything? Well, that might be the case, since this comes up so darn often. But, it is wrong. The full structure must be maintained. This is true of many tapeless formats and more than just FCP. Avid and Premiere need this for certain tapeless formats too.
    a) Harass the people that make FCP 7.0 and make sure that the next update solves this stupid/idiotic/ridiculous oversight.
    It isn't an oversight. It is designed like this on purpose. You need to learn how to do things right. You obviously know what that is now...keep the full card structure. So now it is up to you to continue to do things properly. Instead of insisting that an NLE conform the way it works to suit your needs.
    b) Someone could let us know about a workaround to this that may be the folder structure that FCP needs to be able to do L&T (needs to be simple so that everyone can do it. This would be the best short term solution until part a is completed)
    Easy. Shoot a small bit on another card. Look at the folder structure. Recreate that structure in your backed up footage. Often this will mean making folders with exact names, even if they are empty. But if they have files in them, even small ones, then the first backup you did might not work....because those might be some of the small files FCP needs in order to do the L&T process properly. Always worth trying though.
    c) Buy one of the converter programs such as ClipWrap, Toast Titanium or Aunsoft mts converter. If so which is the most/ least recommended and why?
    I highly recommend Clipwrap. Mainly because I haven't tried the others. But also because the author is always following the latest formats, and works hard to make sure his software works with them. It solved an importing issue I had with the Sony NXCam camera...within a week of me moaning about the issue.
    Want a tutorial to walk you through the tapeless workflow in FCP? I have one. Tapeless Workflow for FCP 7 Tutorial You might know most of this, but watch it for other tips.

  • Render and preview issues with Premiere CC 2014 update

    Rendering issues: Adobe Premiere Pro CC 2014.0.1 Update does not fix" Occasional instance where sequences could never finished rendering"
    It's been 3 days 3 technicians and still same issue. Everything has been tried except starting over which is not an option. Worked
    fine in CS6.  
    1. Optimization of windows and tweek premiere memory settings,
    2. GPU updates,
    3. Software only render,
    4.render section at a time works (but who has time for that),
    5. Tweek virtual memory, - clean cache, clean temp files,
    6. hardware considerations, drives, etc...
    7. Other
    Ceremony completed render except for export in older computer. Please fix issue or give money back until you do!
    The rendering of footage of:
    1. render worked (on complex Ceremony 19 min sequence with AVCHD format and HDV) in an old computer. - Core 2 DUO Quad 8 gb ram 2g
    b GPU
    2. Same sequence of Ceremony (19 min sequence with AVCHD format and HDV) did not work in the faster computer. - i7 QUAD core 16 ram
    1 or 2 GB GPU
    3. Reception sequence of HDV footage only did not on both computer.
    Please call the exterminator and get rid of all the bugs. I am spending more time
    troubleshooting than editing….and that is bad

    You really aren't reading what we write.
    Let's break it down:
    Suitcase isn't working with the new application versions, because Suitcase has bugs in it's code or just doesn't know about the new application versions.
    The only way to fix that is to fix the code for Suitcase.
    Suitcase is written by Extensis, so only Extensis can fix the code for Suitcase.
    So you are waiting on Extensis to fix their code to work correctly with the new applications.
    This is not about the CC 2014 applications, this is about Extensis code not working, and Extensis needing to provide an update to make their code work.
    To get a working version of Suitcase (which requires fixing bugs in Suitcase), you need to talk to Extensis.

  • Video editing & playback issues: Adobe Premiere Elements 8

    Hello all,
    I have made several attempts at transfering HD video  files from my camcorder to my PC and then editing.
    When I try to play the transferred file, it is a little choppy and then gets worse as I edit it.
    Here are my specs/config:
    System:
    HP Pavilion a6720y
    Windows Vista 64 bit
    NVIDIA GeForce GT 440
    AMD Phenon 9550 Quad Core 2.2Ghz
    6GB RAM
    640GB SATA drive, 7200 rpm
    Camera:
    Sony HDR-XR150
    Editing Software:
    Adobe Premiere Elements 8
    I copy the video files from the camcorder to the computer via USB 2.0.
    When I connect the camera directly to the TV the video plays without any issues.  So I know the AVCHD files are "good" and I suspect they are also possibly "good" on my hard drive, but just cannot be played or edited appropriately for some reason.
    One input I received was that due to the nature of AVCHD files, I should convert the video to "I-frame codec" and then edit.  Can Adobe Premiere Elements do this?
    Any other thoughts/ideas?
    Thanks for any help.

    so my boot drive is not used for the media cache folder and files

    You are a music conductor, with a baton that you use to point to various parts of the orchestra... this is like Windows pointing to various parts of the hard drive to do Windows housekeeping or to load program segments for various functions
    Now, at the same time and with the same hand... while still using the baton to conduct the orchestra... pick up a bow and play a fiddle... this would be doing something with your video file at the same time as all the other work
    You as a person cannot do both at the same time with the same hand
    A computer is a LITTLE better, in that it can switch from one kind of task to another very quickly... but not quickly enough for EASY video editing
    You need AT LEAST two hard drives (separate drives, never a partition http://forums.adobe.com/thread/650708 for more) with Windows (or Mac OS) and software on your boot drive, and video files on a 2nd drive so the boot drive is not slowed down by trying to do everything
    I find that the three drives I use work very well for me, for editing AVCHD video... some people use a 4th drive, so video INPUT files are on drive three and all OUTPUT files are on drive four... I only bought a mid-tower case instead of a full tower case (my bad... but had to fit in the space available on my office desk!) so I use the three drives that will fit
    Depending on your exact hardware (motherboard brand & model AND USB2 enclosure brand & model AND external hard drive brand & model) AND the type of video file, you may... or may NOT... be able to use an external USB2 hard drive for SD (Standard Definition) video editing

  • Sony AVCHD (MTS) shimmering lines issue (moire? aliasing?)

    I have just started working with AVCHD / MTS source files (29.997 fps, 1080p) and have been experiencing a problem with shimmering straight horizontal or diagonal lines. The source files look fine, but upon exporting / converting to a common format for veiwing (e.g. H.264, MPEG2, FLV, etc), any detail in frame consisting of high contrast straight lines or sharp edges exhibit shimmering. High contrast horizontal lines and diagonal lines are the most problematic, though even the sharp, high contrast edges of lettering on placecards (panel discussion) have the same shimmering issue. Also, the shimmering appears as a change in brightness, i.e. light to dark, at a frequency of about 2 Hertz, though the frequency can vary slightly. I have tried converting from AVCHD / MTS to nearly every available export format available, tried all of the different frame rates available, and have tried using other available attribute variations, e.g. Profile, Level, Bitrate Encoding, Target Bitrate, Max Bitrate, Render at Max Depth, Max Render Quality, Frame Blending, etc.
    Perhaps there is some format selection that needs to be changed in camera in order to avoid this issue in the future? 
    I will research further, but presently have no idea as to what can be done to solve the issue.  :-P

    What are your Sequence settings?
    Are you certain that they exactly match your footage?
    ...common format for viewing (e.g. H.264, MPEG2, FLV, etc),
    These are all compressed export formats... it might help to
    elaborate on exactly what settings you have used in these cases.
    Have you tried exporting to something 'lossless'?
    If yes, do you still see the artifacts?
    How are you viewing your exported video to judge quality?
    Have you tried re-importing your exported file into Premiere
    for side-by-side comparison with the original footage?
    You might post 'before' and 'after' images to illustrate your issue.

  • Lightroom 5 file edited in photoshop cc 2014 does not appear back next to original after save. Is anyone else having this issue? If so what is the fix.  The edited image appears back in lightroom in a new folder.

    Lightroom 5 file edited in photoshop cc 2014 does not appear back next to original after save. Is anyone else having this issue? If so what is the fix.  The edited image appears back in lightroom in a new folder.

    I'm performing a normal "Save", not "Save As". Work flow I'm using is as follows:  Select photo in Lightroom 5.7 >" Edit In" Photoshop CC 2014 > (after working on photo is PS) > Save > close PS. Photo returns to Lightroom 5.7 in a new folder rather than next to the original. Prior to purchasing the monthly plan and upgrading to PS CC 2014, I performed this same work flow using Lightroom 5.6 and Photoshop CS6 without any issues.
    Just for fun... I attempted to move the edited file back into the original folder. I received a prompt that said the file already existed in the original folder, however I can't see it except the new folder that LR created. I tried several different sort orders, etc without any success.
    *** Follow up: Was unable to resolve the issue using Photoshop CC 2014. Uninstalled PS CC 2014 and went back to using Photoshop CS6. Return trips from LR 5.7 to Photoshop is now performing as it should: returning edited photo back to the original folder in LR 5 and placing next to the original image.
    Should anyone have a suggestion on getting Photoshop CC 2014 to do the same, I would love to be educated.

  • The best Mac MTS Splitter-Editing/splitting AVCHD MTS/M2TS videos successfully on Mac

    I have recorded a long video with Sony HDR-CX700 Camcorder, but there are some parts I would like to cut off. I once thought a video converter is a must for cutting videos.But I search for a long time , found may spliter and converter just for windows, no MAC. Yesterday, my friend recommended me try Aunsoft Final Mate for Mac. Not only can help me  frame by frame cutting/splitting AVCHD without re-encoding, but also can help me convert mts to Apple ProRes and  AIC  codec for Final Cut Pro/ iMovie.
    I think should have many users need a program that allows for  (frame by frame) cut AVCHD MTS/M2TS videos files.If you are looking for any frame accuracy solution to do with the AVCHD videos encoded in MTS format on Mac,  Aunsoft Final Mate for Mac is the best choice for you. This is the first Mac software which can help HD camcorders users to realize frame by frame editing/splitting AVCHD MTS/M2TS videos successfully on Mac.
    Here I would like to demonstrate the simple steps to cut AVCHD MTS/M2TS videos files without re-encoding on Mac.
    Step 1. Load AVCHD MTS videos to Aunsoft Final Mate for Mac.
    - To load AVCHD videos from camcorder
    Connect camcorder to computer with USB cable, and run Aunsoft Final Mate for Mac, you will be asked to follow the wizard. Otherwise, click the Camcorder button to load camcorder videos.
    You can choose to backup the videos to computer or just import videos. Here we just select Import to add videos from camcorder to the program.
    Step 2. Add MTS files for split with no recompression.
    Click the Add movie button, and a movie for lossless output will be created by default. Select the MTS files you would like to cut mts from the Camcorder tab, drag and drop to the movie.
    Step 3. Split/Cut AVCHD video.
    From the timeline, you may notice the vernier, which is used as time pointer. Click on the Vernier, and move to the timeline you want to cut, and click the "Split" button to cut the video. You may also click the Split button when the video plays to the point you want to cut.
    Then click on segment you want to cut off from the timeline, and then click the Delete button next to the Split button to remove the unwanted part.
    Step 4. Export videos without conversion.
    Choose Export in the main interface, and click the OK button to get videos without recompression. You will get the cutted/splitted AVCHD without quality lost in a few minutes.

    I hear good things about ClipWrap. The other good one is Voltaic HD  from Shedworx.
    I suggest that you read their websites and choose the best one for you.
    I think they have demo versions.
    If you import directly from your camera, you don't need these.
    Also, for future reference, you can use the Create Camera Archive feature on the Import screen. This will save your AVCHD files exactly as they are on your camera, but it will also preserve the metadata from your camera so that iMovie can import it later. It is a good way to save the contents of your camera at its original size and full quality.
    When you import AVCHD into iMovie it is converted into Apple Intermediate Codec for better performance, but it will be a larger file size because it is less compressed.
    With ClipWrap, you have the option to keep the file at its original size, but I would not recommend this for performance reasons. (But you can try it if you have a powerful Mac).

  • 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.

  • Multi-camera AVCHD editing workflow in Premiere CS4

    I have a client project that has me wondering what workflow to use and I someone on this forum probably has the expertise to know the right solution. My requirements...
    1. Client is recording a scene using 4 cameras at once, like a live TV show is shot, all AVCHD footage, 1920x1080px 17mbs, square pixels.
    2. I must playback in Premiere the 4 video streams in real time and choose one camera to output, like a director would switch a live TV show. So, all 4 streams are playing in Premiere's multiple-camera editing windows. Each show I'm editing is about 1 hour long. The advantage of multi-camera editing of course is I can play all 4 cameras at once and live switch between them in Premiere to arrive at a 1 hour show in 1 hour of editing time.
    3. Until I can upgrade my hardware that can possibly handle 4 streams of AVCHD, I'm stuck needing a workflow to convert the original AVCHD to some  lowres format, edit those offline low res copies to get my edit decision list, and then reconnect the online HDV AVCHD clips to export through Media Encoder for a final production. My output format is Flash F4V 640x360 px square pixels for Internet playback.
    4. Hardware: I'm running Windows 7 RC using CS4 Premiere 4.1, 4gb RAM, 2.4ghz dual-core processor with 64mb Intel turbo boost on a notebook PC. I do have 4 hard drives to hold each camera's footage on its own drive, and a fifth drive to ouput the edited version to, in addition to a drive to hold my OS and Premiere. The external drives are connected via eSATA to the notebook.
    Question 1: what do you suggest as the lowres format I should convert my AVCHD footage to for multi-camera playback/editing in Premiere?
    Question 2: do you think it's even possible to buy a desktop PC that can handle playback of 4 multicam AVCHD native format files in Premiere in real time? I'm concerned this may be too much for even the most powerful systems, and I would need to resort to editing lowres footage even with the most powerful desktop. As you know, decompressing one or two AVCHD streams is taxing to a PC so 4 at once is a challenge.
    Question 3: an alternative workflow would be to feed live video out of the HDMI connectors on the cameras into four HDMI capture cards (Intensity Blackmagic) and capture uncompressed HDV bypassing AVCHD compression altogether, but the disk space required would be substantial. Does this make sense? I've even considered feeding those 4 HDMI feeds into a video switcher between the cameras and PCs but the cheapest solution I can find that can provide genlock (frame sync) between the 4 cameras for clean glitch-free switching is quite expensive, thousands of dollars invested.

    I must playback in Premiere the 4 video streams in real time
    Good luck with that.  Many folks have trouble with even one stream.
    edit those offline low res copies to get my edit decision list
    I'm not sure offline editing with AVCHD will be possible because of the folder structure.  You may not be able to 'replace' the lower res copies with AVCHD.
    My output format is Flash F4V 640x360 px square pixels for Internet playback.
    Oh, man.  Shooting HD of any flavor is just overkill that adds unnecessary work to the process.  Have your client shoot in DV.

    I'm sorry for a MOST obvious couple of questions, but we need to get them out of the way... 
    Exactly HOW are you switching layers?  If by clicking with the mouse, exactly where on the layer panel are you clicking with the mouse?
