hello,
i'm new to this forum, and i hope that i am posting this message in the right place.
i would like to shoot a 5-8 hour continuous shot in HDV. the idea is to then convert to H264 and play back in real time for a gallery exhibition.
can you shoot continous footage to disk for that long? i have done this same project in DV, and it worked fine. but in HDV?
the live capture part is possible - i tried that out with the sony Z1U and an 2ghz imac G5, but as others have noticed, the capture is at 1/2 or less real time, because the computer is converting to the AIC(Apple Intermediate Codec). i am guessing that at a certain point the buffer room would run out and the computer would crash - can anyone confirm?
Other questions:
1. i have read that on dual 2.5ghz G5's the "ingest time" is in real time. can others confirm this? what about on dual 2.3's? (where i live, you cannot buy 2.5's anymore - just 2.3's or 2.7's)
2. is there any file size formula for AIC? with dv i could count on my files being around 13 gig's for an hour of footage - what about AIC.
3. because i don't need to edit my footage, just record and playback - is there any way to record just the HDV without decompressing to AIC? could this be played back somehow through via firewire to an HDV deck?
4. with dv one can "play through to camera". is this possible with hdv?
Thanks so much,
k schmidt
