Recording audio & video separately -- should audio be 44 or 48KHz?

Hi all,
I'm trying to record some casual family/home music performances, but I'm hoping for respectable quality.
My current plan is to record the audio in Ableton, video in my camera, and sync them in Sony (Vegas) Movie Studio -- replacing the audio captured by the camera with audio captured on the computer.
My understanding is that video uses 48KHz audio, wheres 44KHz is pretty standard for conventional audio.
I'm curious to know whether I should be recording in Ableton at 44 or 48KHz (or, for that matter, 96KHz). eg, is it somehow "bad" to merge 44KHz audio into a video file?
Conversely, if I record in Ableton at 48KHz, is there a problem if I later want to use that on, say, a CD?
THANKS!

Thanks! If you render an H.264 video from Vegas, does it then convert your 44KHz audio into 48KHz? Or does the video file contain 44KHz audio?thecontrolcentre wrote:I've used 44k audio in Vegas. Works fine.

I don't know. I've only used it to prepare dvd's. Exported the video as mpeg and audio as 44k wav (iirc).turnstyle wrote:Thanks!

Thanks -- if anybody happens to know, I'm very curious to hear what you think.thecontrolcentre wrote:I don't know. I've only used it to prepare dvd's.

I'm really hoping to avoid an "oops, should have done that differently" situation...

I tell our students to stick to 48KHz (as per DV standard) for audio for video projects and 44.1K (as per CD standard) for audio-only projects.turnstyle wrote:Hi all,

Merging in 44.1 kHz audio into a video: yes it works fine. But most probably a sample rate conversion is done, which can be avoided if audio was recorded at 48kHz.
Is anybody able to tell the difference? Probably not...

I haven't had any problem using audio files with different sample rates in Vegas Platinum 10. I do generally render at 48K because as whyterabbyt notes it's the industry standard.
I'm working on a project in Final Cut Pro/Express right now that REALLY makes me miss using Vegas!

What if it's *both* a video and CD project?whyterabbyt wrote:I tell our students to stick to 48KHz (as per DV standard) for audio for video projects and 44.1K (as per CD standard) for audio-only projects.
