Unable to Initialize Capture Device - Works fine in iMovie

Am using a Sony HDV HDR HC1E Pal Handycam
Final Cut Pro 5.1
QT Pro 7.1.3
Works fine with cassettes in HDV - imports into FCP fine
Am trying to import a cassette recorded on that camera in DV LP
Works fine in iMovie
Have deleted the QT packages and reinstalled QT
Still am getting the 'Unable to Initialize Capture Device' message when using log and capture.
Settings on camera
VCR Auto (have also tried HDV or DV)
iLink conversion off (i.e.don't convert hdv-dv)
TV type 16:9 (have also tried 4:3)
Component 1080i/576i also tried 576i
Annoying thing is that works fine in iMovie but not FCP?!!
Any help GREATLY appreciated!
Thanks!

I would like to add the following in hopes that someone will come up with a solution. The problem lies somewhere in Quicktime and the FireWire capture. I have the exact same camera and problem, and can assure you it has nothing to do with cam settings or DV LP. Once your system is stuck in this HDV mode, it would seem that regular DV can not be used again. I also have 2 other DV cams that are not HD. One is PAL, one is NTSC. I would further add that my external FireWire iSight no longer works in any application. I do not receive error messages, I simply get the spinning beach-ball of death.
I have a Dual G5 2.7 with 4 gigs RAM running FCP 5.0.4 on OS 10.4.8
I have run Cocktail, rebuilt permissions and re-installed Quicktime 7.1.3 four times as per Apples tech article 301852
I have used FCP Rescue 5 to clear preferences
I have captured footage from both regular DV cams to iMovie and then added the footage to FCP. The footage plays on the screen of both DV cams flawlessly via FCP. (I can also capture HDV in iMovie as well)
I have tried logging footage directly through the QuickTime application with both DV cams and my iSight and get the same beach-ball of death as FCP.
Why can iMovie work with these devices flawlessly yet QuickTime can not.
Why does it seem like the system is stuck in some kind of HD mode.
Just to point out the obvious:
I have no other FireWire devices other than the cameras and I only connect one at a time.
I have shut down, disconnected and re-connected before attempting to use the devices.
I have booted my G5 from a second system disk and everything (HDV cam PAL DV cam NTSC cam and iSight) function flawlessly on all the FireWire ports of my machine.
I have worked with FCP for about 6 years and Macs for 20. I understand the easy set ups etc.
Spent way too much time customizing my system to think about the clean install route, so I hope someone can shed some light on this.
Thanks

  • 5.1.4 update breaks HDV capture? Unable to Initialize Capture Device

    Problem:
    Final Cut Pro cannot capture standard 1080i60 HDV footage from Sony FX1 camcorder. FCP reports "Unable to Initialize Capture Device" when the log and capture window is opened. However, the footage CAN be captured in iMovie (which is interesting, and unacceptable). When HDV>DV downconvert option on camcorder is activated, footage CAN be captured as anamorphic SD, so the camcorder and FW do work.
    The problem is occuring on a rock-solid FCP system that I use on a regular basis (mainly for SD editing). It has been approx 2 weeks since I last attempted a HDV capture, the system has been working great with SD footage (still does).
    Factors that have changed to my knowledge since HDV capture was last functioning properly:
    *Added a new external FW drive into regular usage (a different brand than normally used, no issues with it so far).
    *Updated FCP to 5.1.3, and then 5.1.4 when that fix came out. All SD captures and work have been fine so far.
    Here's what's interesting...I had a copy of the FCP v5.0.4 .app that I had saved an archive of prior to the crossgrade update. Guess what? I can load it up, and it captures HDV without any problems! With that in mind, this looks like an FCP 5.1.4 issue. But I am at a loss on how to proceed further in troubleshooting. Many thanks in advance for any assistance.

    FresHDV.com
    ---NOTES---
    What I have tried:
    *Attempted capture with a different Sony FX1 camcorder.
    *Swapped firewire cables and system firewire ports.
    *Attempted capture with camera FW chained to an external HDD.
    *Unplugged all other external firewire devices from the system.
    *Trashed FCP prefs using FCP Rescue 5, created new project using Easy Setup (for HDV).
    *Tried different variations of FCP A/V settings, tried all the HDV FW device control presets and the HDV AIC capture preset.
    *Per instructions at http://docs.info.apple.com/article.html?artnum=301852 I removed the numbered Quicktime pckg Receipts and re-installed the latest version (7.13). Post-install/reboot, I repaired Disk Prefs and Verified the disk using Disk Util.
    *Have also attempted installing QT 7.13 2 and 3 times in a row, also trying disk prefs repair BEFORE the post-install reboot.

    I think I figured out this vexing problem. I too was having the same issue. Check to see that your Quicktime is newer than 7.1.2. If it isn't you'll have to upgrade it. I only upgraded to 7.1.6 here because I was afraid of going to a really new version. http://www.apple.com/support/downloads/quicktime716formac.html. After I upgraded my quicktime, I ran software update and the Final Cut Pro 5.1.4 update appeared. I hoipe this helps.

  • Unable to Initialize Capture Device

    Hi,
    I am having a problem importing/capturing HDV video from my JVC HD GR 1 getting "Unable to Initialize Capture Device".
    I have been able to capture fine up to this point, finicky some times to be sure, but workable, then in the last few weeks it began getting more and more finicky (wouldn't connect to camera, restart and it works fine), until just the other day it wont connect no matter what I do!
    Help?
    Ask questions if you need clarification.
    Camera: JVC HD GR 1
    Tape: Mini DV
    Format: HDV
    Software: FCP 5.1.4

    Unfortunately when both "Capture" and "Device Control" presets are not set to HDV it wont even try to connect and gives me this warning:
    "To capture HDV source material, both the Capture and Device Control presets must be configured for HDV; otherwise, to capture in another format, both must not be configured for HDV."
    As a side note when my camera was connecting to FCP. FCP would only give me on screen controls half the time.

  • Unable to initialize capture device and device control in HDV

    I shot with a Sony HVR-Z1U/Z1N and am using a Sony HDV 1080i tape deck to digitize.
    I recently purchased a MacBook Pro and installed FCP Pro 5 on it. After getting over some time code issues we were chugging along, when on the 4th tape the image on the log and capture screen suddenly dissapeared (I could get audio and could see the image on the tape deck). Well after taking the tape out, checking and rechecking it I popped it back in and ever since then, I have been getting this error mssg "Unable to initialize capture device and device control."
    I have tried deleting the preferences and starting from scratch. If I do that, and choose the easy setup with HDV- 1080i60, it gives me this error "Unable to locate the following external devices- HDV (1440 X 1080) 30fps.
    I upgraded to FCP 5.1.2 this morning and upgraded the OS to 10.4.7 and QT to 7.1.3 and still no change.
    Im at my wits end, Ive been working on this for a whole week now.
    Thank you,
    Bugs

    It has been reported to take more than one attempt to correct the installation but, if properly executed on a machine without other system problems, the QT reinstall process does work. The key element here is you must reinstall QT after you trash the receipts. The process is listed below.
    x
    To do a full quicktime reinstall.
    Go to /library/receipts and delete any files that say Quicktime followed by a number e.g. Quicktime703.pkg
    Go to the Apple quicktime site and download the appropriate version of Quicktime to your hard drive.
    Run the Quicktime installer.
    Repair Disk Permissions for your System Disk (Disk Utility > Select the system disk > Repair Disk Permissions)
    Reboot
    If this doesn't work, then the problem lies elsewhere:
    1. your system - user preferences, firewire ports or other system elements.
    2. your equipment - camera/deck/firewire cables.
    3. your process - not setting up the software properly or using the software erroneously.
    Listed below is a troubleshooting process. Not all steps are appropriate but the general process of isolating the problem is useful.

  • How do I open a library book on a recently acquired Samsung Nook?  I get "too many activations" error. I have an active adobe digital editions and my other devices work fine.  Custumer Support was unable to get the new device activated.

    I have a library book on the bookshelf of a newly acquired Samsung Nook but I cannot open it.  My other devices work fine but I cannot activate the new unit.  I get a "too many activations" error message.  Customer Services say I have a valid license but they deemed my problem to be a technical issue and referred me to the forum.  Thanks

    Step 1 - by trial and error...
    So far, I have been able to create physical files containing MP3 and JPG on the NAS using the Windows XP systems to copy from shared locations on the Vista and Win7 boxes.  This process has been aided by the use of a 600 GB SATA 2 capable hard drive enclosure.  I first attach to Win 7 or Win Vista and reboot to see the local drive spaces formatted on the portable device.  Then I copy files from the user's private directories to the public drive space.  When the portable drive is wired to an XP box, I can use Windows to move the files from the portable device to the NAS without any of the more advanced file attributes being copied to the NAS.  Once the files are on the NAS, I can add the new folder(s) to iTunes on any of the computers and voila, the data becomes sharable via iTunes.  So far, this works for anything that I have completely purchased, or for MP3's I made from the AIC files created when I purchased alblums via iTunes. 
    I have three huge boxes full of vynl records I've accumulated.  The ones that I've successfully digitized via a turntable attached to the sound card on one of my computers and third party software, have found their way to the NAS after being imported into iTunes and using it to bring down available album art work.  In general I've been reasonably well pleased with the sound quality of digital MP3 files created this way, but the software I've been using sometimes has serious problems automatically separating individual songs from the album tracks and re-converting "one at a time" isn't very efficient.

  • Couldn't initialize capture device

    I am not able to capture any video from my webcam (Logitech USB Camera). I am working with linux red hat 8, so maybe it's a Linux issue (I got the liux jmf-2.1.1). Anyway, when I try to create a player or processor I get a NoPlayerException, but my webcam is found when i call Vector devices = CaptureDeviceManager.getDeviceList(new RGBFormat()) and I am able to locate the camera with MediaLocator loc = device.getLocator()(Media Location is v4l://0 in case it matters). But when I try to create a player I first get an IOException: Couldn't initialize capture device and a NoPlayerException.
    JMStudio is able to initialize the capture device but I just get a black screen. But I can take snapshot images without a problem.
    I am actually working on a robotics vision project for my university and i need the camera to plug it on the robot for vision problems.
    thanks, muriel

    I've had the same problem, I have a Lego camera (basically a quickcam) and it works fine under Linux with the qc-usb driver. Under JMStudio, it is detected, and I can capture from it, and this will work for any user, not just root. When I try to list the devices from my own Java code, however, I don't get any devices. If I run the V4LAuto class (found in the JMStudio source), the camera is detected. Either way, it won't initalize when I try to use it. I've looked through the JMStudio source code to try to see what it does differently so that I can use the device.
    On the camera, the light comes on to say that someone is requesting the stream with my own code, but the stream fails to initalize.
    I'm running RH9, kernel 2.4.21 (qc-usb won't work on 2.4.20-8). Does anyone know if this has to do with a permission in Java? It shouldn't, but it might.

    Does the iOS device see the network?
    Any error messages?
    Do other devices now connect?
    Did the iOS device connect before?
    Try the following to rule out a software problem:                
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.

    Back up all data before making any changes.
    Step 1
    Take all the applicable steps in this support article.  
    Step 2
    If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
    Step 3
    If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
    From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
    If the application called "Bluetooth Setup Assistant" is running, quit it.
    Step 4
    This step will erase all your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.
    Triple-click the line below on this page to select it:
    /Library/Preferences/SystemConfiguration
    Right-click or control-click the highlighted line and select
    Services ▹ Reveal
    from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
    Step 5
    Reset the System Management Controller.
    Step 6
    Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional — ask if you need guidance.
    If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present. 
    Keeping your confidential data secure during hardware repair
    *An SSD doesn't need to be zeroed.
