Recording audio for 35mm vs DVCProHD

I have been recording HD sound on a Tascam HDP2 at 23.98 without any issues for the last several months. Now, a friend has asked me to help him record sound for a 35mm short that he's making. I said I'd help, but I feel like I'm in over my head.

What do I need to do differently for recording 35mm than for the silly HD projects that I've been doing? Do I simply change the frame rate to 24? Are there any other settings or adjustments that I need to make? I'd hate for him to use his limited film stock and have the sound be totally out of synch or horrible. :(

Can somebody help!!

Thanks in advance!
 
Depends on his camera. If he's shooting at 24.000 fps, yes change the frame rate to 24, and slate the takes.

If he's shooting at 23.976 fps, leave it at 23.976.

If he's shooting on a "wild" camera, (meaning, not crystal-sync) then you've got issues left and right. In cases like that, try slating at the head and tail of the take so at least you have a reference point for how far the sync drifts during the take...
 
Aside from matching time code numbers or when using pulldown, the audio's nominal "frame rate" is actually irrelevant. It's going to (typically, for film) be 48KHz in any case. Digital audio playback speeds are determined by a clock that controls the sample rate (ie: 48K, 44.1 for CDs, etc.). A frame is strictly a film-reality since a motion picture consists of a still frames that can be viewed as such. Audio's rate is determined by its desired bandwidth (20Hz-20KHz or better). You could think of the samples as "frames" but with 48000 of them going by in a second it's not particularly meaningful. And there's no such thing as a "still" or "freeze-frame" in audio...
 
35mm

35mm

Thanks for the replies everyone.

One of my concerns, which prompted my post, was that several people had told me to record at the Tascam's 30fps mode because of the telecine process. Not knowing about the process, I was/am nervous about not having an accurate rate to match the frame.

So, I'm still a little confused since I have heard both 24 and 30 (at 48.048) at this point.

Wait so you suggest to go "over" not under on the khz rate?

I though best match would have been
24.00 PsF @ 48,000hz slown to 23.976 PsF @ 47,952hz in Telecine and not
24.00 PsF @ 48.048hz slown to 23.976 PsF @ 48.000hz in Telecine.

The latter would work better for episodical shows shot on film, but shown on TV, while the former would suit theatrical projection better, NO?

Im personally not "suggesting" anything.
It is what it is.
35mm= 30ND 48K (48.048 if post requests it)


It's the standard.
That being said..post can request anything they want..so I suggest talking to them,
if you cant talk to post.. 30nd 48 is the surefire bet.
