Video stream : Synchronization of two screen

Hi
In my project I have to create two or more screens, each feeding on different source. In addition I must be able to synchronize these two screens to the same time, exactly.
Is it possible? How reliable is JMF in this regard?
Any link, advice, idea will be highly appreciated.
Bye Yuval

There are currently better sync features in the works!
I know your frustration. For a similar and more in-depth discussion, see another thread I posted in here: Batch syncing audio and video using timecode
Unfortunately in CS6 (what I currently use)  it creates a separate track for each clip, which can be a mess if you have hundreds of clips. The best way I have found to make things easier is to create a separate TC synced multi-cam sequence for each individual cameras footage.  For example, I follow the same steps you did for each of my cameras footage independently so that I have a TC synced sequence for camera A, a TC sequence for camera B, etc. Then you can select all the footage of each sequence, nest it, and copy each nest into a master sequence to work with. What you end up with is a single clip for each camera. MUCH easier to work with!  To keep track of where clips start and/or end in the nested sequences you can go into your original sequence and place a marker (shortcut "M") at each clip. These markers then show up in your Mastertimeline clips for reference.
I know things could be easier, but this is currently the best option I know of. I already put in a feature request and was told by the Engineering Manager of Premiere Pro that new sync features were in the works. (see thread link above)
Hope that helps!
...and for the record, here is my TC sync process:
SELECT ALL clips you wish to sync from your Project Tab/Window.
RIGHT-CLICK and SELECT "Create Multi-camera Source Sequence..." In CS6 it is the next-to-last option in your popup window.
A dialogue box will appear. For the Synchronize Point, SELECT the box that says "Timecode" and UN-CHECK "Ignore Hours"
You will now see a new multi-cam sequence in your Project Tab/Window.
RIGHT-CLICKyour new multi-cam sequence and SELECT "Open in Timeline"

  • Video streaming stalls in full screen mode

    I'm not sure to be in the right category, but my Laptop runs in Tiger and I happen to use video streaming from different websides like ESPN Live and other websides with their own players. I use even some that require a program dowload to be able to see their content. By all those sources the video runs pretty smooth in a normal size. As soon as I put it to full screen it stalls in a certain rhythm no matter if the whole program is buffered or not.
    I achieved better results with one of the providers using WMP that via flip4mac streams into Quicktime. Just don't know if and how I could incorporate those other webside players into Quicktime. And if this would be the solution.
    I freed up some of my HD to achieve better performance. Have 18 GB free out of 100.. is this too little ?
    Do I need a better video card ?

    Ba,
    It may be of interest to know that streaming video codecs are designed for computers of a specific age (CPU and GPU speeds).
    DVD quality streams MPEG-2 compression at about 10 Mbits/sec, and the older MPEG-1 compression, designed for NTSC television, streams at about 2 Mbits/sec. At 10 Mbits/sec, the processor must work faster to decompress & display the image. The latest compressions are based on MPEG-4. Even a G3 iBook could display MPEG-4 full screen; so I don't think you need a faster GPU.
    Microsoft codecs & containers, the last time I checked, were ancient: based upon MPEG-2. So, check your speed:
    DSL Reports speed tests
    http://www.dslreports.com/stest
    If you use Wi-Fi, IEEE 802.11n is fastest.
    Increase the cache size for your codec, if you can. It needs to be contiguous, so I dare to recommend iDefrag 2 (US$30) to clean your remaining disk space and obtain about 20 GB of contiguous space. Video display uses many operating system files, which are likely not fragmented; but you can also de-fragment the Windows codec if it lies in over 100 fragments. (The Spotlight database usually has over 1000 fragments; but pauses in it don't affect one's pleasure in using it.)
    My low-resolution DVD is interpolated by my graphics card, and look beautiful at maximal resolution. Streaming graphics apparently isn't programmed to interpolate low resolution: it demands high resolution and high bandwidth.
    If you can't increase the cache in WMP, you can lower the resolution of your monitor. That may be why this System Preference was designed to sit on the desktop's top bar.

  • Synchronize on video stream with mplayer

    Hello,
    I recently bought an EasyCap DC60+ USB adapter. It is an RCA -> USB adapter which is recognized as an USB webcam by the kernel.
    I installed the easycapd60 module and it works fine for video with no sound, but I can't get audio working correctly. It looks like my audio stream is 1 second late on the video stream (I get the sound one second after the image).
    The problem is that mplayer is synchronizing the playback on the audio stream (I think). That means that my video stream is delayed in order for it to be in sync with the audio stream. As I want to use this DC60+ adapter to play video games on my computer screen, I can't tolerate a 1 second delay.
    A solution to this problem would be to ask mplayer to synchronize on the video stream instead of the audio stream, then play with the A/V sync parameters to get the audio synchronized. But I can't find the parameter to do this in the mplayer manpage.
    So my question is the following : does this parameter exist ? And is there another solution I didn't think of which could solve my problem ?

    Did you have to do anything special to get the DC60+ to work?  I've got one installed using the em28xx driver and it eventually makes my USB mouse stop responding, and sometimes the whole system crashes after that.

  • Full screen videos/streams on second monitor won't stay full screen while using another window on other monitor

    Whenever I open and then full screen a video or stream of any kind, I am unable to use another window of Firefox while the video/stream maintains full screen. When I click off the video/stream it reverts back to the smaller screen. Is there any way to change this?

    Create a new profile as a test to check if your current profile is causing the problems.

    When i select the "Full Screen" option in video streams (like youtube, veoh, anything like that) i can do that one(1) time second(2nd) time the screen goes blank and can only exit it with the escape(Esc) button and then i have to restart firefox and again i have my one "Full-screen Ticket"

    I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
    When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
    At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
    I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

  • Multiple Video Streams on Same Monitor or Screen

    Is it possible to merge multiple video streams on the same timeline in PP CS5? I have a customer thats wants me to do thisfor him.

    Charles,
    What the client is asking for is PiP (Picture in Picture), and Colin has outlined the method for creating the PiP.
    I also find it easiest, when doing a lot of PiP work, to use alignment grids, to help me with both the Scaling and the Position. This ARTICLE goes into a bit more detail. For PiP, I will usually create a custom alignment grid, similar to this:

  • Synchronizing 2 Video Streams

    Hello everybody
    I implemented a small application that reads an MJPEG Stream from an Axis Camera. The components arrive as single JPEG Images of which each has stored a timestamp in its comment header. For a 2 Camera experiment I need to synchronize the two streams by this timestamp. The app has 2 threads, from with each reads the images from one camera. Another thread gets the latest image from each camera-thread,stores a local reference to them and draws both. I need to make sure that both images have the same timestamp before drawing.
    Is there a good coding pattern on synchronizing 2 (video) streams to avoid common mistakes?
    if yes, please let me know. Thanks.

    Luis,
    I have heard good things about Ripple Training and the guys behind it on the FCPX Grill podcast, so I will check it out.  Thanks for the reminder.  I had been using Lynda.com, and it is not bad, but their training seems to be a little out of date at times.
    Tom,
    Not trying to question your advice, just curious why it wasn't working for me. So I found a video showing that using the Synchronize Clips function with multiple video and audio clips does create a compound clip (see 4:00-5:00):

    Baffles me why mine isn't working that way...

  • Capturing multiple video streams into a movie file

    I am using QTKit to capture 3 media streams simultaneously: audio, video, and display (display is screen capture), and would like to capture them in a time-synchronized fashion to a single .mov file.
    I have been able to successfully capture these three streams to 2 separate .mov files by using 2 QTCaptureSessions (one for audio/video, one for display video), but the problem here is that the 2 files are not time-synchronized (I have no idea how to synch them after the fact).
    The more intuitively correct thing to do is to use a single QTCaptureSession instance with 3 inputs (2 video inputs and one audio) to do the capture, which should automatically synch all the streams. Furthermore, since the .mov file can support an arbitary number of streams, I figured wiring up the QTCaptureSession to output to a single .mov file would be easy. I was wrong.
    The problem is that even though my QTCaptureSession has 3 nice input connections (2 video and 1 audio), when I wire up a QTCaptureMovieFileOutput to it, the resulting QTCaptureMovieFileOutput object has ONLY 2 connections: a single video and a single audio.
    Here is snippets of what I am doing:
    // add audio input: (type of media is QTMediaTypeAudio), succeeds
    [qtSession addInput:[QTCaptureDeviceInput deviceInputWithDevice: qtAudioDevice] error:&qtError]
    // add video input: (type of media is QTMediaTypeVideo), succeeds
    [qtSession addInput:[QTCaptureDeviceInput deviceInputWithDevice: qtVideoDevice] error:&qtError]
    // add display input: (type of media is QTMediaTypeVideo), succeeds
    [qtSession addInput:[QTCaptureDeviceInput deviceInputWithDevice: qtDisplayDevice] error:&qtError]
    // create file output
    QTCaptureMovieFileOutput * qtFile = [[QTCaptureMovieFileOutput alloc] init];
    [qtSession addOutput:qtFile error:&qtError];
    // PROBLEM: if I look at this array of connections, it has ONLY 2 connections
    // 1 video, 1 audio!!!
    NSArray *connections = [qtFile connections];
    // start capture running
    [qtSession startRunning];
    // wire up to my file
    [qtFileOutput recordToOutputFileURL:[NSURL fileURLWithPath:outputFileName]];
    I desperately need help....my questions:
    1. Since QTCaptureSession supports arbitary inputs, and QTMovie supports arbitrary # of streams, I can't believe it's not possible for me to simply "hook" all the inputs of QTCap to output connections that will write to streams in one movie file. Clearly, QTCaptureMovieFileOutput is not doing this...can anyone tell me how to do this? This can't be hard, right?
    2. If I have to fall back on the ridiculous approach of capturing 2 unsynchronized .mov files and somehow synching them after the fact, can anyone provide a pointer on how to do that?
    Thanks VERY much!

  • No audio video streams upon import of .mov files?

    Hi... recently upgraded OS onto Intel 240 GB SSD. Running Widows 7 64 bit, clean re-install, 24 GB RAM, NIVIDIA Quadro FX 4800. I have been trying to optimize the system for maximum GPU accelerated effects while also taking advantage of the high speed read and write of my disk. OS runs on SSD, Adobe media cache on separate 2 TB eSATA connection, Media stored on external drive USB 3.0. Without getting into the fine details this is a snapshot of my workflow.
    The few problems I am encountering are some .mov files cannot be imported to PP. Error reads no audio or video stream in the files. I suspected metadata issues so tried to import with media browser and still no luck. These files worked perfectly before I began surgery 2 days ago on my computer. I have installed the latest version of quicktime and yet to no avail. Any recommendations here regarding my issue with imports or suggestions to benefit from my hardware would be appreciated.

  • .Mov files in CC : The File Has no Audio or Video Streams

    I recently updated premier to CC , since i have issues iimporting any .mov files at all.

    I can verify that Apple screen recordings without audio do not import into any Adobe premeier.
    Details on screen recording from Gspot v2.70a:
    H.264
    qt  : Apple QuickTime (.MOV/QT)
    File Type: QuickTime (.MOV)
    Mime Type: video/quicktime
    Len: 1:03.083
    Frms: 1,521
    Qf: 0.153
    Frames/s: 20.000
    wx: 1280 x 800
    sar: 1.600 (8:5)
    However Apple (MAC OSX) screen recordings WITH audio will import.
    I would think this should be fixable with hotfixes...
    If you (adobe staff) have access to macbook pros 2012 or 2013 models, open quick time pro, do a screen recording, make sure no audio is recording, just your screen movements.. then export to 1080p video (mov is only option).. then on a windows PC try to import that file into adobe premiere. The file will play perfectly fine natively in windows with any player so long as a H264 decoder is available on that system... the problem here is Adobe Premiere. Not the users system.
    Edit:
    To help those with this issue.. just make sure when you render your mov that you have ANY kind of audio in it.. and just remove the audio track once imported into premiere. I know it's frustrating and you would think something as simple as not having an audio track wouldn't break premiere but alas... we have to work around the shortcomings until they decide to fix it.. just like the VFR issue in premiere.

  • RMBP, Chrome, Youtube: Video delays when in full screen

    Hi all,
    I have a retina Macbook Pro running Mac OS X 10.8.2, Chrome 25.0.1364.99. When I watch youtube videos there is normally no lag. Once I switch into full screen mode, there's a slight delay where instead of the video the screen will show a blank white screen before switching to the video.
    This results in a slight 0.5-1s lag of the video behind the audio.
    Opening the same video on Firefox and going to full screen doesn't result in this blank white screen and does not result in video lagging behind audio.
    Any suggestions?
    Thanks in advance.

    Thank you,

  • One of my two screens stays off after coming from standby - OSx 10.10.2 MacMini

    When 'reviving' my macmini after not using it for a while one of my screens stays black (The screen stays off so there is no contact from the mac). Even after logging in again the screen stays black.
    I can get it to work again by disconnecting both screens and plugging them back in, but that is not a real solution of course. Also, after switching the position of the screens the other screen stays off, so the problem should be in the connection.
    I've got a relatively new MacMini with OSx 10.10.2 and have the two screens (same size but not identical) attached via two 'mini displayport to DVI adapters'.
    Does anyone have any idea what can cause this?

    I already have radeon.modeset=0 on the end of my kernel line, I think I disabled KMS a month or two ago when it was (very briefly) enabled by default.  IIRC my system was very broken with KMS enabled back then, I haven't tried turning it back on.

    Well as you can tell this isn't very active especially when your asking a question in a cross platform trouble shooting forum.
    You don't say what computer you have so no one can even guess, you should put the model/year of the computer your on and the Mac OS version your using into your profile so we can help you better. (Example, 2010 MacPro, OS10.6 and Windows 7.)

    From what I understand your Mac needs to support dual monitors and you need to have 2 video ports available and just get an adapter if needed for the connection between the computer and the monitor.
