Mkv with multiple video tracks

Hi. I have a load of Matroska files which contain a few (about 5) short video clips and an audio track. The video clips in each file are of the same event from different angles, so I want to watch all clips simultaneously. I have installed Perian and while the files open, I can only see one track, and I don't hear any audio. (MKVinfo tells me there are definitely multiple tracks.) Is it possible to use Perian/QuickTime to watch all video tracks simultaneously? If so, I can't figure out how, so I'd appreciate any pointers.
I've tried VLC, and while this also opens the files (and shows all tracks), it invariably crashes soon after opening.
If anyone has any other suggestions how I might solve this, that would be great too.
Thanks in advance,
wrathkeg

It could be a 'difficult' form of Matroska file. FYI Matroska is just a container like MOV or AVI, and some mkv have the video encoded with Real Video Codec (RV9 RV10). Perian+QT can't decode this, but VLC will play .mkv files just fine on OS X, as long as they don't use H.264!
It's a bit of a lottery until Matroska decide to support the Apple platform. I have found this:
http://mkv4mac.free.fr/index.php?lang=en&p=lec
which may help.
But there may be another workaround: 1. Get Info the mkv file
2. Change to extension to wmv. Save as wmv and that could work better.
Or this link may be helpful:

Recently, a poster (ZachP14) suggested this:
"There's a program called Plex that runs .mkv files awesome on my 2.0 ghz macbook."

Maybe worth a try?

  • Best method for building a project with multiple video tracks

    I'm working a project where a client wants some edits made to an existing DVD they had - some video tweaks but mostly menu changes. I'm rebuilding the menus from scratch and I've ripped all the video files from the DVD (there are about 80 of them on one DL-DVD), transcoding them with DV-DVCPRO/NTSC settings.
    The problem is when I import them all as assets into my project build, the DVD disc meter shoots up to about 12 or 13gb. What I've done is added them all to their own separate track, as they're meant to be played not as one continuous video but individual sessions.
    What I'm wondering is if there is a better way to build it that would reduce the amount of space it takes up (I'm rather new at DVD Studio Pro, so I can't tell if I'm going about this the wrong way or not), or if I need to compress the video files or re-transcode them using some other settings (H.264? I'm trying to maintain as much video quality as possible).
    Any help on this would be much appreciated, thanks.

    What is the running time? You should encode to m2v and AC3. Take a look here

  • Working with multiple video tracks

    When I have 2 video clips on different tracks at the same time, there is a red line above the track and, if I try to play the movie, the word "rendering" is shown during this section.
    I have a long clip on track one and want to add a small cutaway shot on track 2, while keeping the audio of track 1 going.
    Since I need to adjust the video in/out/placement in track 2 so it works with the track 1 audio, I can't keep re-rendering at every tweak. There must be a faster method.

    All the video was shot in 1440x1080, at the exact same camera settings (Canon Vixia HF100, LP mode). However, the sequence is 1920x1080 (which was the setting of a previous project).
    If I try to change the sequence settings to 1440x1080, the image gets stretched. Any suggestion?

  • Shot matcher with multiple video tracks and clips bug

    Hello again,
    Very problematic bug : at least in direct link mode, when using shot matcher, if the shot to be matched is on top of other clips below, then it produces odd results. In a word, it doesn't work.
    Can't think of a workaround or another workflow right now, so, again, very problematic.
    Fred

    As I'm producing a music documentary, it's often handy not to erase a clip beneath another one when there is a temporal continuity and the clip above only is there for a temporary angle change.
    Thank you very much for this idea anyway.

  • Multiple video tracks to line up with audio- iMovie or Finalcut??

    I am trying to make music videos, like this: http://www.youtube.com/watch?v=aEzpIAdsur8&feature=channel_video_title
    I have iMovie, and my main problem is getting the video to line up with the audio. I can make the audio tracks like up just fine, but then I am stuck with just one video clip to use, I cant go back and forth between different video clips of me playing different instruments because I can't line them up perfectly with the song. Help?
    I have been debating wether or not to get final cut express 4, because from what the reviews say it allows multiple video tracks to be used. Would that solve my problem?

    This forum is for mobile iMovie (iPhone & iPad).

  • How do I copy and paste text style for multiple video tracks?

    hello,
    I am creating multiple video tracks with text.  I want to easily copy and paste the style, i.e., Font, Color, Size - rather than having to scroll down the giant list of fonts to find the one I want, then change the color, then change the size - each and every time.  This is arduous.
    I tried copy / paste of one text onto a new video track, but when I type in a different word, it alters the original.
    I have 9 tracks of video for 9 different texts that will pop in and out of my video.  I would like to be able to copy/paste then just change the text.  This would save me a huge amount of time.

    I know of no way to alphabetized the Adobe Styles that come with the program.
    If you had the time and the inclination, you could rename them all to force them to appear alphabetically, but that does not seem all that practical.
    But, if your interest is in the Styles that you save and you do not hit the Reset File List, the new Styles will be at the bottom of the list and you can name them so that they appear that alphabetically at the bottom of the whole Styles list. But that does not address the matter of you having to scroll to the bottom of the Styles list.
    In some instances, some things that you think that you cannot do in Premiere Elements obvious features, can be done by computer keyboard shortcuts. I check the keyboard shortcuts under the Edit Menu/Keyboard Customization and unfortuately did not find any that would be applicable to this situation.
    As for your changes in one text file popping up unwantedly in another text file, that is because you have text files with the same name. Look into creating duplicates (with different file names) in Project Assets at the onset.

  • Working with multiple audio tracks

    Hello,
    I'm working with video clips that have a stereo audio track (guide audio fed into the camera) synch'ed to 4 mono tracks (recorded from a variety of boom mics and lavaliers).
    Although I've linked all the audio clips to the video, it still gets a bit cumbersome when performing T or L cuts. When I hold down the Option key, I still have to adjust each of the audio track separately.
    Is there a more efficient way to deal with multiple audio tracks? Maybe some way to treat these audio tracks as one unit?
    BTW I'm working in FCP 7.
    Thanks,
    Thien

    One way:
    Lock the video track.
    Use the Edit Selection Tool to Select the audio transition points
    This will automatically open the Trim window, where you can move the cut point - in this case I am moving the audio cut(s) 30 frames later than the video cut:
    which gives me the displacement of all the tracks that I wanted:
    You can use this quite quickly once you get used to it.

  • Multiple Video Tracks

    With Imovie HD, just wanted to know if it was possible to have multiple video tracks and how? Also I cant seem to find the 'project library' or any 'advanced' tool section...
    Cheers!!

    Hi
    No there are no "Multiple video tracks" in iMovie any version.
    If it is the effect "Picture in Picture" Then You can add plug-ins from
    third part developer that can give this.
    Stupendous software http://www.stupendous-software.com
    GeeThree http://www.geethree.com
    cf/x. http://www.imovieplugins.com
    Apple http://www.apple.com/downloads/macosx/video/ezediapluginsforimovievol1.html
    http://www.imovieplugins.com/fxhome.html
    But if it is real "Multiple video tracks" You need cheapest and "best" solution
    is FinalCut Express.
    If it is so that You shoot/record with multiple Cameras/Simultanious AND Continous
    Then You would gain greatly on FinalCut Pro (Studio 2 bundle).
    To work with this multi-clip function is Great.

  • Multiple video tracks available???

    I am gradually moving over to FCE from Media100. In one of my earlier post on this forum, I wrote that I need to work on several (4-5) timelines at the same time in one project. I edit documentary work and need this flexibility in developing ideas and different sequences to select the best one. In Media 100, infinite 'programs windows' can be opened within the same project
    I went to an Apple demo; someone suggested I create different project names. Won't work for me. I need to refer to numerous sequences at a fast pace instead of closing out and opening a new project just to see a 45 second sequence, reopening, etc....
    I was informed on this forum that multiple timelines could be nested, but I dont understand this or how this is done. Is there only one video track in FCE? Would these different 'trial' sequences be made up on one video track in a differenet track location?. I see that audio has numerous tracks. Does video has this too?
    How is video nesting done?
    Thanks.
    Billp

    You can have as many sequences as you want in a single FCE project. You can have multiple projects open at the same time. Any sequence can have 99 tracks of video and 99 tracks of audio. By default, though this is user pref you can change, a sequence is created with one video track and four tracks of audio.
    You can have as many sequences as you want open at the same time in the timeline window. You can pull the sequence from the timeline window so you effectively have multiple timeline windows. Your screen will get pretty cluttered pretty fast though.
    Nesting simply means putting one sequence inside another. There are a number of ways to do it. The simplest is to drag one sequence from the browser into another sequence.

  • Dislaying multiple video tracks in FCE

    I have 3 video tracks I want to view all at once. I am an iMovie guy and only use FCE for multiple video tracks where I have several cameras on the subject at diffferent angles. I've read a technique here on how to do it but I don't understand it. They talk of shrinking the tracks to 1/4 size and puting them in separate corners. My tracks are sychronized does moving them to separate corners mean in the time line, if so there goes the timing. Could someone list a simple step by step process for this. I'm guessing they mean 3 canvas windows showing each track but I don't know how to get there.
    Dual G4 1.25 ghz   Mac OS X (10.4.6)  

    1. Double-click the topmost clip and open the Motion Tab in the Viewer.
    2. Move the Scale slider down to 50% and drag the small image in the Canvas to one corner.
    3. Do the same with the other clips. You will end up with 4 quarter size images in different corners of the Canvas.

  • Synchronize multiple video tracks

    How can I synchronize multiple video tracks using iMovie? i.e.: I want to make videos of myself playing different instruments, and then use clips from each to make a music video (with the sound track being all the instruments combined). The problem is having each clip synchronized to the music.

    You would be much better off with Final Cut Pro 7, as it supports multi-cam clip editing.  This feature allows you to do what you want.  iMovie and Final Cut Pro X don't support this type of feature.

  • The point of multiple video tracks

    I am half way through the Adobe Premiere CS3 Classroom in a book and the only time multiple video tracks have been used is when working with multiple cameras and still there the multiple tracks where used only to sync up the four different cameras. In the book, to determine which camera angle to show the sequence had to be dragged into another sequence that was set to multi-camera.
    I see different marketing shots of the Premiere screen with lots of video tracks. How sand or why do folks use multiple video tracks? It seems that all the video transitions are between different clips on the same track, can a transition span tracks? Might there be some good videos or books that might enlighten me to some more advanced usages?
    Sam

    Here's an example...
    Video Track 1 - Clip (main program)
    Video Track 2 - Title (lower third graphics)
    Video Track 3 - Title (lower third text)
    Video Track 4 - Over the shoulder graphic (think "news report")
    Video Track 5 - Bug/logo lower left corner
    Audio Track 1 - Clip (main program)
    Audio Track 2 - Music (underneath)
    Audio Track 3 - Sound effects (whoosh! zing! bang!)
    Audio Track 4 - Audio commentary (director, talent)
    Just something to get your brain going. I've never used more than 10-15 video layers simultaneously (doing green screen work, titles, mattes, etc), and never more than about 6-10 audio tracks. But that's just me....many people need more than that to accomplish whatever they're doing.
    Another thought...even though you "can" do transitions and cuts all on one track for most simple projects, some people prefer to use the track numbers as an organizational structure. Put all your cuts for scene 1 on track 1, all your cuts for scene 2 on track 2, and so on. This can be very useful for scanning the timeline and looking for specific changes in the overall storyline (whereas a single, long track would require another system of organization...either sequence markers or perhaps pure memorization).
    Hope this helps!

  • HELP!! Multiple Video Tracks

    I need to know if you are able to have multiple video tracks and once they are all lined up in the sequence you want, am I able to cut from one video track to another just like you would edit from scene to scene with 1 video track (like in Imovie)? I need to edit a dance recital with video from 3 cameras, so i need to line up the videos so they are all in sync as far as time is concerned, then switch from one video track to another without seeing the other tracks playing at the same time...in essence "mask" the other video tracks I don't want to see, but keeping all three video tracks in time and sync'd.
    If yes....then I'm buying Final Cut...if no...I need something else!
    Hope you understand what I'm asking!!!
    Thanks, DJ

    You can do it though FCP does it more efficiently.
    It is a bit fiddly in FCE though Piero's free PIP filter makes it a bit easier:-

  • Snow Leopard iTunes 10.5 will not play multiple video tracks in QuickTime .MOV files

    I recently discovered that Snow Leopard iTunes version 10.5 won't play multiple video tracks in a QuickTime .MOV file.
    Both video tracks appear and play correctly when playing the file in:
    - QuickTime Player 10 or QuickTime Player 7.7 on the same Snow Leopard machine
    - iTunes 10.3.1 on another Snow Leopard machine
    - iTunes 10.5 on Leopard or Windows 7
    So I think the problem is iTunes 10.5 on Snow Leopard (although I haven't been able to test iTunes 10.4).
    First test file is two 640x480 video tracks side-by-side (total dimensions 1280x480):
    http://160.94.17.23/demo/two-video-tracks-1280x480.mov
    All I see is the first (left) video track, and not the right one.  iTunes "Get Info" command incorrectly reports the video dimensions of the file as 640x480.
    Second test file is two 640x480 video tracks played one after another (duration of 10 seconds each):
    http://160.94.17.23/demo/two-video-tracks-640x480.mov
    All I see is the first video track, and although it reports the correct file duration (20 seconds), the second video track never appears -- it simply freezes on the final frame of the first video track for the last 10 seconds.
    Anyone else see similar behavior?  Unless I'm missing something, I suppose I should submit this as a bug to Apple.

    I have the same problem, i tried re-installing, converting it to AVC H264 but none seems to work so far

  • Export to Quicktime with multiple Audio Tracks?

    Hi all --
    I am on a tight deadline (48 hrs!) to deliver a Quicktime Prores file with 6 audio tracks: ch 1+2 dialog, ch 2+3 music&effects, ch 4+5 stereo mix. I'm working with FCP 6.
    Now, I have figured out how to export the FCP 6 project to a Quicktime file with multiple audio tracks (in the Project settings, I specify 3 stereo channels, then I assign each audio track to one of the channels and export everything to a Quicktime file).
    However, how can I send a stereo mix to channels 4+5?? FCP only allows me to assign each audio track one but not multiple output channels, and I didn't see a way where I could create a bus.
    Can anyone help?
    Thanks!

    Something is being miscounted here. You say you have dialog on 1+2 and then say you have M&E on 2+3? I think you meant to say 3+4 and the stereo mix will be on 5+6. The easiest way to do this is to copy tracks 1-4 to tracks 5-8 by shift-option-dragging them there. Holding option will copy the tracks instead of moving them and holding shift will insure that the tracks will not move earlier or later. Then send 5+6 (dialog) to the 5+6 output (using the info in the above referenced discussion) and send 7+8 (music&effects) also to the 5+6 output. Done.
