Optimal sound capture format for Vegas?

I am starting to use my sony digital audio recorder to record and provide sound tracks in my Sony Vegas 8b video projects.

I am wondering if if is best generally to capture the audio files in the same format the final project will use, i.e. 16b/48K, so Vegas does not have to render/convert the files. Im assuming every time they are rendered, some loss is happening.

I originally was thinking I would capture all audio in 24b/96K, but Im not so sure this is a good use of resources except when it's required for later audio editing.

I would also like to know if there is any problem with using the Sony 16b SBM feature when using the audio for video tracks in Vegas. The Sony PCM-D50 literature does not reccomend it but I don't know why, and it sounds better.

Thanks.

If your projects are for video record your audio at 48KHz. Recording with 24 bits will give you better end results. If you can't do 24, 16 is OK. There's not much benefit to 96KHz.
SBM (super bit mapping) has data encoded into the audio and will cause problems if not decoded properly - I don't think many applications can so avoid this record format unless you are going to use the analog output of your recorder.
I hope this is helpful,

I record stuff destined for CD at 44k1/24 bits. For video at 48K/24 bits. If y ou want to up the SR, that's a consideration for you to make based on system throoughput, available space, and if you perceive any audio benefit (thouh experimentation).

Unless your digital recorder has mics that respond well above 20KHz, then to my mind the is no question of recording at anything more than 48K SR.

Thanks for the replies!

I am getting great results at 24/48 with a manageable, although still pretty big, file size.
