Claes Jonasson, of Film & Company, LLC, writes:
I used to record live training sessions, with a quick turnaround to
finished DVDs. To cut out the time spent capturing the footage off
tape, I brought my PowerBook and a hard drive with me to the shoot
and fed the firewire DV signal into the laptop. Then I used the capture
now in Final Cut to capture the live video (not forgetting to make
sure I had no maximum length set to capture now).
That meant that as soon as I was done, I could do the minimal editing
(the hard drive with the footage could just be moved to my desktop
computer) and be done. In my case, I ran 3 cameras through a DV switcher
and also included audio from an audio board.
Frequently I would also do a backup recording to tape or DVD of the
signal that the computer was recording, just in case something bad
would happen.
Doing it this way saved on equipment, and allowed me to provide finished
programs later the same day, or the next day.
Larry replies: While I do not, as a rule, recommend using Final Cut
for live capture because if you lose that file on hard disk, you've
lost everything; still, you have an interesting method which I am happy
to share.
Claes then sent this:
I understand why you might not want to recommend as a general practice
to record to disk through Final Cut, which is also why I would normally
do a safety recording on tape.
You might be interested to know that at the church I attend and where
I am part of the video team, we record the sermon live and transmit
it to 3 other sites, each with a different delay (in the range of 2-5
minutes). Our setup is all Mac-based, with xRAID at the center. We
record on one Mac (can't think of the software we use for that--the
same software is used by broadcasters for delaying/editing live events)
and write the files to the xRAID. Then 3 other Macs are used for playback
of that file, chasing about 10 seconds behind. When the message starts,
each of those Macs, using Final Cut, gets cued to the starting point,
and we edit in a bumper. Then when a site is ready to go, we use print
to video to send the message to them. This system has been in use for
a couple years now every Sunday and works quite well. Only on rare
occasions do we have dropped frames.
Larry replies: Very cool. Thanks.
