7D and the H4n

I have my 7D on the way(F*ck YEEEEEESSSSSS) sorry bout that its been a long time since I was this excited... I just received my H4n ... I know that with the 5D at 30 frames the audio has to be slowed a bit... I am primarily gona be shooting in 24 and 60... so I have a few questions... about the H4n

1. Shooting at 24 frames... what should I record at for best audio, also will it need to be slowed at all in post

2. The same question as before, this time for 60 frames but I am only shooting 60 for slow motion then set to 24 frames...

by the way I love this forum and this community you are all so helpful... Majoring in film it is my hopes to some day be able to work with such fine people as yourselves...
 
1. I'd always use 48KHz/16-bit. The 7D shoots at proper video rates, so you shouldn't have to slow down or adjust the audio. With that being said, be aware that there's always the possibility of a little sync drift on longer takes between any two devices.

2. Well, not sure what you mean -- any audio you record during a slow-mo take is going to be basically useless, right? It'll be done playing before the footage is even 1/3 of the way through playing back. What would you do with it? And, I guess it doesn't really matter because you can't possibly have any sync between the slow-mo footage and the realtime audio, so why not record at standard 48KHz/16-bit and make it easy on yourself?
 
I used a DVX100b in 24p to record a live band . The sound guy used a zoom H4. He just emailed me the song. I just put it in the FCP timeline and it worked. It was no hassle at all. I didn't tell the soundman what setting I was using either. I plan on buying a H4n once I get a vDSLR.
 
Say I shoot a slowmo pin drop... just an example and I want the sound to match... thats what I mean not spoken word of coarse... lol thanks

I highly doubt you'd be able to pick up the audio of a pin drop. In films, most of that kind of audio is done by the sound designers...
 
You are taking this to seriously I said for example... I just want to know how much it would need to be slowed for 60 frames

OT: In a quiet room with a decent mic and the right surface, pin drops can definitely be recorded.

You would need to slow the audio by whatever percentage you are slowing the footage. If you are going to 720p/60 to 720p/24, the footage is being slowed ~40%. You would then need to slow the audio by ~40%. At least, that seems to be the logic of it.
