Using an XCDAM-EX Video Camera as a Webcam

Thursday, September 20th, 2012

If you put an XDCAM-EX camera in 1080-SP mode then it generates HDV, which is 1440×1080 but with brick-like pixels and data is at Constant Bit Rate (CBR), a requirement of HDV.  For an XDCAM-EX3, there is a small iLink/Firewire connector at the back, it can be enabled/disabled by the camera’s menu.If you then run Skype, it sees the image, scales it down to Skype-format, namely 640×480 with square pixels, hence 4:3 aspect ratio.   However it does not allow for the difference in pixel shape, with the result that the image looks squashed horizontally.  A nuisance!So I wonder, is there any  interposing software that can e.g. map the pixel shapes properly or even allow some kind of zoom/pan of a (e.g.) 640×480 frame within available (e.g.) 1920×1080 (equivalent, when pixel-shape converted) image from HD or HDV camera?

    • The EX in HDV mode (SP) and iLink has worked for me. I’ve done it with Telestream Wirecast (another COW forum you’ll find my floating head) for live streaming.
    • Someone having difficulties, others offering advice on XDCAM-EX settings, though I’m not convinced that all of them are necessary)
    • Debut Video Recording software (free)
    • Instructions:
      • Connect the video cable plug on the USB video-capture device to the video input on the camera cable. Video cable plugs and inputs are usually color-coded yellow.
      • Plug the camera cable into the camera.
      • Plug the USB video-capture device into an open USB port on your computer.
      • Download “Debut Video Recording Software 1.42” or a later version and install the application on your computer.
      • Launch the software.
      • Click “Device” from the toolbar menu and then go to Step 7. If the software doesn’t recognize your HDV camera, click “Options.” Click the “Video Capture Device” arrow and select your camera from the list. Confirm that the “Format” and “Device” settings are correct or make changes, if needed. Click “OK” to continue.
      • Click the “Skype” icon on your computer’s taskbar and select “Open Skype.”
      • Right-click the person you want to call under “Contacts.”
      • Navigate to “Share Your Screen” and select “Share Selection.”
      • Use your mouse and drag the black box down to the inside of the video-capture software’s display area.
      • Resize the black box to fit within the display area.
      • Click on the “Start Screen Sharing” box in the upper left corner of the video display area.
      • Click “OK” in the Screen Sharing dialogue box. A “Starting Video” message will appear.
      • Wait until the person you are calling picks up. The “Screen Sharing Active” message confirms the connection

Video Surveillance & Multi-Webcam Software

Wednesday, January 18th, 2012

I saw in the Sony Vegas forum that GiveAwayOfTheDay (GAOTD):

  • Zebra-Media
      • Video surveillance and motion capture  software.
      • Some key features are: unlimited cameras (including IP and USB cameras), motion detection, SMS and MMS and Email alerts, play sound file (useful on motion detection), adjustable sensitivity for each zone, record on detection, save video into archive or file with automatically or manually selected compression, record on schedule, registration of all events continuously by intervals or on motion detected, password protection, adding a text, time stamps, watermarks to your video.
      • For each video frame, if motion is detected, the Alarm event occurs, that returns a global motion ratio, depending of the number of cells in which motion has been detected, and the level of motion in each cell
      • A sensitivity grid is applied on video frames. You can adjust the sensitivity of the detection, and mask out areas of the camera view to avoid false alarms. When the camera captures video frames in a dark environment, it is possible that the electrical background noise of the CCD video cell creates fake motion detection events. It is possible to reduce the sensitivity of to the video noise by enabling the Reduce Video Noise option. When an alarm condition is detected, the program can sound an audible alarm, or send you an email with a photo. Automatically capture photos, or record video in compressed files. Surveillance System includes an advanced player that allows to play video clips, capture video frames and perform frame overlay. Each camera has its own individual monitoring and recording settings. All settings, such as alerts, photos, and video recordings can be turned on and off using the built-in scheduler. All monitoring and alert events are logged with date and time stamps. Each camera has its own scheduled on(off) times. Building upon the interface options introduced in MS Outlook, scheduler includes event recurrence control and customizable Date Navigator. Access to all data is provided through a well encrypted password

Some alternatives indicated by reviewers:

  • iSpy:
      • Open Source
      • iSpy uses your cameras, webcams, IP cams and microphones to detect and record movement or sound. Captured media is compressed to flash video or mp4 and streamed securely over the web and local network. iSpy can run on multiple computers simultaneously and has full Email, SMS and MMS alerting functions and remote viewing
      • iSpy is probably the worlds most feature-rich surveillance software. Some key features are: Unlimited Cameras and Microphones (including IP and USB cameras), Motion Detection (3 types), Motion Processing (4 types), Record on Detection, Record on Schedule, Record with Audio, Remote Access, Network Audio Broadcasting (via iSpy Server), Password Protection, Desktop Recording, Automated YouTube Uploading, SMS and MMS and Email alerts
  • YawCam
      • Yet Another WebCAM (software).
      • Yawcam is a webcam software for windows written in java. The main ideas for Yawcam are to keep it simple and easy to use but to include all the usual features.
      • Yawcam features:
        • Video streaming
        •  Image snapshots
        • Built-in webserver
        • Motion detection
        • Ftp-upload
        • Text and image overlays
        • Password protection
        • Online announcements for communities
        • Scheduler for online time
        • Time lapse movies
        • Run as a Windows service
        • Multi languages
