  • Downconverting / Capture Now / Start Stop Detect

    Posted by Gnostic on July 12, 2006 at 1:07 am

    I’m downconverting HDV to DV 50 (with an M10U deck and AJA LH transcoder.) The normal capture, Print to tape, etc works fine, but I have tried “Capture Now” (which captures fine, ) but after capture I do “Mark > Start /Stop Detect” and I get a message: ” The clip you have selecte does not reference a movie that can be analyzed.”

    Is this because I’m down converting, and it is not DV?

    [Michael] “Is this because I’m down converting, and it is not DV?”

    it is because you are down converting a non digital signal via component out of the deck.

    there is not any time code either..

    DV Start Stop only works with DV 25 AFAIK.

    AND it only works with camera masters… It’s using the time of day code built into a DV-25 cameras. When it sees a jump in time (every camera pause would cause this in time of day code) it creates a marker.

    I have always thought it was any video over FW – it works from varicam tapes via the 1200a deck

    Thanks Gary,

    I am outputing a component video signal out of the M10U into the AJA, but I’m also directly outputing a firewire time code into the G5. When I capture, I set the device control to “Firewire NTSC” which controls the deck. I had thought that this made the FCP happy with a digital time code signal.

    Sorry Michael
    It is not the same – it is my understanding that the aux TC track which gives you the start stop detection gets stripped out when you do the analog down-conversion–

    This aux timecode is in different locations with different settings in HD vs SD – just like Closed Captioning is in a different location and format in HD and not completely transferable.

    Thanks to all,
    This makes sense with what is happening. Before our HDV adventure, I was outputting DV25 to an analog DV50 signal, so this also would have stripped off the camera cut signal. Too bad. The drill now is to capture everything and put the markers in manualy.

    Thanks again,
    Michael
