  • aaaarrrrgggh Regen Timecode vs REC IINHIBIT.

    Posted by Alister Robbie on January 8, 2007 at 7:22 am

    ok, I am at a loss here, so if anyone can give me a heads up, I would be greatly appreciated.

    for the last week or so, we have been shooting with a pair of HDC27F’s. most of our footage has been shot at 720p25/60, but I have one tape that has been shot at 720p60/60. now I have managed to capture the other 13 tapes into our FCP system via our BlackMagic decklink card fine and without any worries, but it is the 60fps that is giving me the irrits.

    FCP 5.1
    BMD 5.7.2

    I have the edit suite set up correctly so that I can capture 60fps no worries. The only issue is that because of the way Final Cut captures the footage, I really need to be able to black the rest of the tape . (Long story, can explain if needed)

    For some reason, the HDC27F we still have seems incapable of regenerating the timecode off tape. I have been through all of the settings including making sure that TCG SET HOLD is set to off, and that FIRST REC TC is set to REGEN. On the outside of the camera, the TC is set to R-RUN, and that is about it. I hit the record button, and the timecode is always wrong. (I have even tried making a note of the timecode that is on tape when paused, and setting that to the preset, but this is always out as well.) On a Sony camera, I would normally have just switched the TC setting to REGEN and off I go, but not so on the Panny. So, having run my head into a brick wall there, I tried to black the rest of the tape using the deck.

    When I stick the camera tape into the deck, the REC INHIBIT light comes on. I have checked the tape, and the REC INHIBIT switch is off. I have checked the front of the deck and the REC INHIBIT switch is also off, yet for some reason the REC INHIBIT light is on. Running my head into a brick wall on this one as well.

    If anyone has any clues, I would be really appreciative.

    Cheers

    IF this is meant to be offspeed footage you should not get camera timecode with the capture.

    IF you are laying back to tape – FCP does not send or read TC over SDI- you will need to generate the TC from a serial connection (and why are you doing that with a camera)

    WIth FCP you have to Black and Stripe tapes before they are recorded on.

    True, but unfortunately, FCP will abort the capture if there is a break in the timecode. Due to a “feature” of the BMD drivers i need to capture the additional footage after the footage that I intend to use so that it will rationalise it out to the footage that I need. and please don’t misread me here. I am not bagging the guys at BMD, as this “feature” allows me to capture offspeed footage with no rendering, and no FRC

    but I should be able to get the deck/camera the regenerate it’s own timecode. all I am trying to do here is to black the rest of the tape with continous timecode. it shouldn’t be difficult. i am trying to do it with a camera because that is where it should be easiest. I don’t need to see the black footage, i just need something there. if I could get the camera to regen timecode off tape, then I would just point it at a wall and let it record that for 25 minutes. when I get a sec this morning I will do the maths, and explain why I need to record footage with continuous timecode on the end of the tape, but at the end of the day, this should be a really really simple operation.

    i think this would have been simpler if I had explained it thus:

    we have been shooting at two different frame rates -25fps & 60fps. I have switched from a 60fps tape to a 25fps tape to shoot some stuff, and now need to switch back to the 60fps tape so that I can keep shooting 60fps. For some reason the camera I am using will not regen the timecode on tape, and that is causing me some concern as for my NLE to successfully capture the tape, I need to have continous timecode. are there any settings on the camera that I am missing?

    thanks,

    al

    [Alister] “True, but unfortunately, FCP will abort the capture if there is a break in the timecode. “

    you need to change the setting in FCP to create new clip because all of the VFR data has”broken timecode” – it changes with the change in cadence. – I am able to capture VFR data direct with a Kona card and not have that issue.

    [Alister] “but I should be able to get the deck/camera the regenerate it’s own timecode. all I am trying to do here is to black the rest of the tape with continous timecode.”
    No you need to stripe the tape first – thats why you stripe the tape and do an insert edit.

    As for the camera settings – when you take the tape out of the camera – you can force the TC to regen- however WHY? you have discontinuous TC and you will create massive problems in the post process by nat having enough pre-rol and post roll

    This is not the correct way to work in post with VFR footage,- leave longer pre/ post roll and us different TC for each frame rate so that your editor understands the footage is at a different frame rate.

    There is only one frame rate on each tape. That way the editor (me) doesn’t have to deal with multiple frame rates on the one tape.

    In a way, my issue is that not enough post roll has been left, so I was hoping to be able to put the tape back in the camera, get it to pick up the existing timecode, and continue from there and record some more footage to give me the post roll i need with timecode that continues frm the existing timecode on the tape.

    I have gone about this another way, completly bypassing this timecode issue, and my issue with capturing so all is good.
    For reference, I have captured the offending 60fps footage as 60fps, then used Shake to retime it or remap it to 25fps as required. Simple, quick, and I didn’t need to worry about post roll or the timecode.

    Gary, thanks for your time in responding. Apologies if I did not seem to be making much sense.

    Cheers
