open ended capture with timecode
hi is there a way to do an open-ended capture on fcp? i’m using an hvr-1500 with serial (9-pin) control via decklink. what i’d like to be able to do is mark an in at the beginning of the tape and have it pre-roll and then capture everything up to the next timecode break. when the machine senses the break, it should create an out. ideally, i would like it to then roll forward, mark a new in on the next section of the tape and create the next clip. this is pretty standard working procedure on an avid, is their a similar function on fcp?
before someone suggests using capture now, let me explain why that is not going to work. i need frame accurate timecode info associated with my clips so that i can batch capture later. with capture now, there is no pre-roll. without pre-roll, there is no frame accuracy.
thanks very much for your help, josh

Hi Joshua,
AJA has an application so you can control the desk and manage the TC (AJA VTR Exchange).
In order to do the same with a DeskLink you would need a similar software.
No idea if its exists.

What hardware doesn’t take the source timecode when digitising from tape on a “capture now”?
I’ve done that for years (on both Avid and FCP) and never had a problem going back to redigitise clips later. That’s how we used to do the old offline at low res/conform at high res workflow, so I just take it for granted that you can do that.
[Mind you, I started in tape suites so when I started using NLE’s (which was in 1994 or 1995 IIRC) I was shocked that when you plugged in an RS422 cable to the deck you ALSO had to tell the software what kind of deck it was! So what do I know.]

thanks, rafael. yes the decklink has rs-422 control. my issue is with fcp. capture “now” doesn’t use pre-rolling so i don’t see how it can be frame accurate. capture “clip” does pre-roll but it requires you to specify an out in advance which is a pain. i’m looking to do an open-ended digitize with pre-roll.

thanks. maybe it’s me just being old school. i was taught back in the day that you needed pre-roll to have 100% frame accuracy. capture “now” doesn’t use pre-roll so i don’t trust it. am i wrong?

Is nothing about hardware, but about FC.
FC can’t take the TC embed in an SDI.
With an AJA you need RS-422 + the software I’ve mentioned.If you are using FW, is a different story.
FC can take the TC from the stream.[joshua schwarz] “i was taught back in the day that you needed pre-roll to have 100% frame accuracy.”
There is pre-roll when capturing with FW.
Must be somewhere to set the preroll for your VTR, but as i said you need the software to control the RS-422.

rafael”i have the preroll for the rs-422 set. it works fine when i mark the in and out and use “clip” to capture. it doesn’t do anything when i use capture “now.” “clip” doesn’t allow open ended capture. you must have an outpoint. i haven’t experimented with firewire capture and timecode. maybe this isn’t the basic question that i thought it was. i’m going to start a thread on the main forum. thanks for your help.
