Digibeta Transfer newbie question at DVinfo.net

Hi,

I need to export some footage and transfer it to digibeta, the footage is shot on Panasonic HVX200 HDV 720p (24p) and edited on Premiere CS4 with the HDV 720p 24p setting.

I got to ask someone from a local transfer service and they said the output file should be in quicktime format, preferably 720x486 uncompressed yuv 10bit 4:2:2 codec. but then he said it needs to be in 29.97fps, even if my footage was shot on 720p (24p) 23.976fps.

So should i really encode the footage with the 29.97fps setting? will it change how the footage looks, especially if it is supposed to have a 24p film look? Also they need 720x486 but the original is 720x480, does it change the aspect ratio a bit too?

Thanks.

Changing the frame rate on export won't affect how the footage looks. It will still have the 24fps look because that's how it was shot. (Same as when you watch a movie shot of film on TV. Shot in 24fps, playing in 30fps.)

6 pixels would be almost imperceptible, but didn't you say you shot in HDV? I thought HDV 720p was 1280x720?

yeah the source is 1280x720, i just wrote it wrong. but then it also brings to another issue, coz when i try to convert the footage to quicktime, it is distorted a bit since the ratio of the height doesn't quite match, coz the accurate down ratio from 1280x720 is something like 720x405. how do you fix it?

Thanks
