Using FW800 as 'scratch' disk for SD video capture does not work?

New iMac buyers beware - if you plan to capture video via FW400 (most SD camcorders do), you cannot capture directly to a FW800 disk. Workaround is to capture to your Mac HD first - there is no problem there.
When my FW800 external disk is mounted and I connect my camcorder via FW400, the FW800 drive keeps unmounting/remounting and is unusable. I noticed on Profiler that iMac groups the firewire devices in the same category (for FW800 and FW400) implying the bandwidth is shared and not independent.
I should have bought the Mac Pro.
Any suggestions?

Looby - yeah, I tried that - works for DV/DVCPRO NTSC (max write of 4MB/sec) but not for uncompressed 8-bit (max 21.52MB/sec) - I drop frames.
George - Yes, using FCP. Maybe, but even without FCP launched, and my OWC 2 drive external on FW800, when I turn on my camcorder on FW400, the drives unmount/remount continuously. Hmmmm... maybe it's the OWC? See below...
Noiseboy - Hmmm... interesting. Is your "lacie 250 triple" a single drive or multiple all in one chassis? My OWC is 2 drive RAID chassis configured as two independent drives - maybe that is the problem. I am going to try removing one drive.
Anyone else buy a FW800/400/USB2 RAID system in hopes to increase thruput? With the OWC I get a whopping 68MB/sec RAID-0 vs. 66MB/sec non-RAID. Bummer. Those advertising people should get what they deserve!
Thanks everyone!

  • Video capture does not work Java 1.5 or 1.6

    I could not run jmstudio on 1.5, but on 1.6 I could, and jmregistry says there is a device with a Locator "v4l://0" and jmstudio can display the video. Yet my old program that worked with Java 1.4 can not now capture the video any more, createDataSource(locator) in the code:
    locator = MediaLocator("v4l://0");
    source = javax.media.Manager.createDataSource(locator);
    throws NoDataSourceException, that says something about "Could not configure video device". Is the code bad? Or is there something other broken? JMFHOME is set correctly.

    Where is your jmf.properties file? Do you have the performance pack installed?
    Does JMStudio work. (if you're on linux w/ java 5.0 use: java -Dawt.toolkit=sun.awt.motif.MToolkit JMStudio)
    My bet is that you don't have jmf.properties in your current dir or the camera hasn't been added to your properties.
    Another idea:
    try this before your code:
    try {
        Class.forName("V4LAuto").newInstance();
    } catch(Exception e) {}in order to autodetect the camera.
    Peace

  • Audio in video messages does not work

    When I record a video message for someone, the audio does not work properly. It either doesn't work at all (silence is recorded), or cuts out after a 1-2 seconds. The problem seems to be confined to the MP4 video/audio encoder used by Skype for video messages.
    My webcam (Logitech HD615) works properly when used for Skype calls (including the built in microphone), and when used in other applications. With other applications, I can also record videos and the audio is captured and encoded correctly. Although the problem does not seem to be the webcam, I have re-installled the webcam drivers and I have tried changing USB ports for the webcam.
    I have re-installed the latest version of Skype and verified that Windows has the latest updates (I'm using Windows 7).  I have tried re-booting a number of times when debugging this issue.
    I have looked at the mp4 file that's created in the temp folder when Skype records the message - the audio is missing/broken regardless of what player I use. This, and the fact that the webcam works makes me believe that the problem is in the Skype use of the audio/video encoder, or the encoder itself.
    Any ideas on how to solve this problem?
    Thanks,
    K.
    Solved!
    Go to Solution.

    When you change the USB ports, make sure not to use USB 3.0 ports. I had a very similar issue with Logitech c920 webcam. Changing the port to USB 2.0 has solved the issue.

  • Satellite 1800-100: video-out does not work

    He,
    I just installed windows XP on my old Satellite 1800-100, but now my video-out does not work anymore. So I just downloaded the latest driver, but there's no way I can get it installed. According to Windows the new driver isn't newer, so it won't let me update it. And when i try to unistall the display driver, I have to reboot before it takes effect, and wile rebooting it automaticly installs the standard driver again.
    Can anybody help me?
    Greets,
    Daan

    Hi
    Do you mean TV- out port or monitor port? As far as I know this unit is preinstalled with WXP Home and all drivers can be also used for WXP Pro.
    Did you preinstall your own OS (non recovery image)?

  • Video Filter does not work.

    Hello.
    I have been using Final Cut Pro 4 for a while and it worked fine before. But recently, any function of Video Filter does not work. I apply them to the clip, but the image does not show any changes on Canvas.
    Is the software's problem?
    Thanks in advance.

    For a reason unknown to me, FCP's preference files (there's 3 of them) will sometimes become corrupted and need to be trashed. Usually the symptoms are things just not working as they did earlier, or weird issues like the 3 Way Color Corrector looks different than before ... stuff like that.
    FCP Rescue is a freeware app (yes, you'll need to download it) that will create a backup set of preferences, thereby retaining all of your settings. Then when (not IF, but when) FCP's preferences become corrupted, you can run FCP Rescue to replace the bad set with a fresh new set.
    Otherwise you can delete the files yourself (make sure FCP isn't open at the time) and the next time you launch FCP, it will revert back to the factory settings.

  • HT201335 when using apple tv with my ipad, the mirroring function does not work, screen goes black, what is the issue?

    when using apple tv with my ipad, the mirroring function does not work, screen goes black, what is the issue?  My son's Ipad(same as kind as mine) works ok with the apple tv but mine does not.  Any suggestions?

    Hello Nina Izurin,
    While written for the iPhone, the troubleshooting below can help resolve issues with your iPad's camera, as well.
    Camera isn't functioning or has undesired image quality
    If the screen shows a closed lens or black image, force quit the Camera app.
    If you do not see the Camera app on the Home screen, try searching for it in Spotlight. If the camera does not show up in the search, check to make sure that Restrictions are not turned on by tappingSettings > General > Restrictions.
    Ensure the camera lens is clean and free from any obstructions. Use a microfiber polishing cloth to clean the lens.
    Cases can interfere with the camera and the flash. Try gently cleaning the lens with a clean dry cloth or removing the case if you see image or color-quality issues with photos.
    Try turning iPhone off and then back on.
    Tap to focus the camera on the subject. The image may pulse or briefly go in and out of focus as it adjusts.
    Try to remain steady while focusing:
    Still images: Remain steady while taking the picture. If you move too far in any direction, the camera automatically refocuses to the center.
    Note: If you take a picture with iPhone turned sideways, it is automatically saved in landscape orientation.
    Video: Adjust focus before you begin recording. You can also tap to readjust focus while recording. Exiting the Camera application while recording will stop recording and will save the video to the Camera Roll.
    Note: Video-recording features are not available on original iPhone or iPhone 3G.
    If your iPhone has a front and rear camera, try switching between them to verify if the issue persists on both.
    My issue is still not resolved. What do I do next?
    Contact Apple Support.

  • Installed Premiere Pro CS4 but video display does not work?

    I just got my copy of CS$. After installing Premiere I found two things that seem very wrong:
    1) video display does not work, not even the little playback viewer next to improted film clips located on the project / sequence window. Audio works fine.
    2) the UI is way too slow for my big beefy system.
    My pc is a dual boot Vista-32 and XP system with 4GB of memory installed and nvidia geforce 280 graphics board with plenty of GPU power. The CS4 is installed on the Vista-32 partition. My windows XP partition on the same PC with Premiere CS2 works great and real fast.
    Any ideas how to solve this CS4 install issue?
    Ron

    I would like to thank Dan, Hunt, and Haram:
    The problem is now very clear to me. The problem only shows up with video footage imported into PP CS4 encoded with "MS Video 1" codec. So this seems to be a bug. The codec is very clearly called out and supported within various menues but video with this codec just will not play in any monitor or preview window. In addition the entire product looks horrible with respect to performance while PP CS4 trys its best to play the video. Audio will start playing after about 30 seconds. And once in awhile part of video shows up at the wrong magnification before blanking out again.
    My suggestion to the Adobe team: fix the bug and add some sample footage to the next release so new installations can test their systems with known footage.

    The Ask Toolbar is causing that in the Firefox 3.6.13+ versions. Uninstall that extension.
    There are a couple of places to check for the Ask toolbar:
    * Check the Windows Control panel for the Ask Toolbar - http://about.ask.com/apn/toolbar/docs/default/faq/en/ff/index.html#na4

    Wow, that's an interesting one - seems as though the sharedCursorPane has
    some hard requirement that the base App be mx (this isn't terribly
    surprising, considering it was built with the mx components, but it's still
    a bug). Can you link against the source code (provided for player 10 now!),
    and change that line in sharedCursorPane :
    From :
    Application(mx.core.Application.application).stage.removeEventListener(Mouse
    Event.MOUSE_MOVE, onMouseMove);
    To :
    stage.removeEventListener(MouseEvent.MOUSE_MOVE, onMouseMove);
    and see if that works for you? I can't honestly tell why we're using the
    line that was there... It's possible this was a workaround for another
    issue. Anyhow, if you wouldn't mind being the guinea pig for this one, we
    can get to the bottom of it.
      thanks!
