  • Double Image from DV Capture

    Hello,

    When I try to capture video from my DV camera (using 1394 and Mediastudio 6.5) the still frames have a double image of fast moving objects (cars). When I view still frame using a field monitor (from the cameras video out) the image is perfect. How can I get the capture to be the same as the original? Is it a progressive / interlaced problem?

    Thanks.

    Doug.

    With out seeing the actual image I would almost certainly say it is interlacing. Check out www.100fps.com for more specifics of de-interlacing and what not. I'll try to give you some basic info as to my understand of interlacing.

    Interlaced video when watched on a non-interlaced display (ie PC screen) will show jaggies and saw-tooth like images, especially when there is alot of action or camera motion going on. If your source/target is a TV, then you don't have to worry about interlacing cause the TV will expect your source to be interlaced and show it properly. If your target is a PC world, then you will have to de-interlace your video before your finalize it.

    I know this is very basic and brief, but hopefully it gives you a basic understanding of why your video is jagged on your PC and "perfect" on your TV.

      Thanks for the reply,

      The image isn't really saw-tooth like but more like a ghost image offset a few millimetres.

        By 'saw-tooth', he means that alternate lines show the position of the object in two places.

          On the subject of deinterlacing. I need to produce some video that will be projected during a gig on stage. If the source footage is interlaced will it be necessary to deinterlace it or is a projected image the same as a TV image?

          Thanks.

          Damian.

            Check the projector specs. Some will project "proper" TV and some just computer from a computer graphics card.
