  • Decompose problem – XpressPro 4.5

    Okay, This is a weird one. I hope for the sake of my sanity that someone has dealt with this before. I edited a show with footage captured 15:1 low-rez. I decomposed the sequence to high-rez my edit and the new clips are all slightly off. Every new decomposed clip seems to be captured from a start point several frames too early which changes the whole edit. I am completely at a loss for what to do. Does anybody have a suggestion?

    What is your source? DV or Beta? If it is DV I can almost bet your off by
    -4 frames. We get this all the time when we offline a DV show on our Xpreess (meridien) then uprez in our DS suite. DV timecode not always the most dependable sorry no real solution but you may want to off set your dig list.

    Take care

    This may actually be an error caused by an offline using firewire control of a deck and an online using rs-422 control of a deck. This is an issue with DV, DV50 and HD100. TC over firewire can have an offset or error.

    The solution is to use the more robust, quicker and professional rs-422 control in your offlines. Which means you will have to take in your video over SDI, composite or component.

    Some DV decks, and Avid software do not like video and audio to come over fire wire while the deck is controlled via rs-422.

    ALSO…do not digitize across timecode breaks…whether using firewire or rs 422. This is an Avid specific issue and relates to all digital formats…including DigiBeta. Do not dump entire tapes in. Make sure your in and out points are withing camera rolls.

    Chris is the man!
    Digitizing across the TC breaks is a sure fire way to hoop yourself! Gotta love learning by experience!
