  • truncate file without recompressing

    Posted by Bob Cole on June 3, 2010 at 8:15 pm

    To avoid the timecode break problem with HDV tapes, I capture without deck control. I’m not always right there to stop capture at the end of the recording, so I wonder: is there a way to truncate – that is, cut the file in length – a Quicktime file, without recompressing?

    I’m using ProRes422.

    Thanks.

    Thanks. I can’t seem to locate Quicktime Pro – is that something that I should automatically have in FC Studio?

    It’s an easy (and cheap) purchase from Apple. Go to the site (https://store.apple.com/us/browse/home/shop_mac/software?mco=OTY2ODQyOQ) and get the license code. Follow the instructions. Simple. You really are quite limited without it. BTW capturing without deck control, and having time-code breaks in the first place, becomes a nightmare if you ever have to reimport the footage. You will regret it one day.

    Plain QT.
    If you have the Export function available, QT Pro is active.

    Thanks Rafael. I’m also told, by friend Weiss, that I do have QT Pro, only it is labeled QT Player.

    I’ve long had your view. But the reality of HDV has forced me to reconsider. If I use deck control, the M25 deck shuttles endlessly on fugitive timecode breaks – bad for the deck, the tape, and for the missed footage. I use the HD Connect to capture via HDMI/SDI(AJA) from the HDV tape, then treat the capture as the “new negative,” backing it up to LTO-3 tape (stored offsite forever) as well as RAID-5 (in the studio, for duration of project and about six months of “afterlife”).

    I capture the first few seconds of each tape with tc, then the whole tape continuously without it, then match the actual tc on the continuous-run tape. I don’t care whether the timecode at the tail of the file is the precise actual tc on the tape. Given the alternatives with HDV tc capture, I vastly prefer this method – it’s faster, gives me access to all the material that was shot, and is easier on the deck and tape. If I actually had to recapture the footage from the original tape, I could do it the same way and probably come close enough to the first “new negative’s” timecode.

    I appreciate your concern, and I take your point.
