HD to tape...DV to card (as it pertains to 24p)

Ed Plamondon · July 20th, 2008, 12:47 AM

Hey there -
Just want to confirm...

If I choose HDV 24P Native, or 24P-A to tape, and then choose DV to the card.... the 24p DV file will not behave the same as the HDV recording correct? That is, going no native 24p DV straight to card, and no 24p-A DV file. Just the 24p over 60i.

That's my understanding anyway.

Will this throw off the notion that the DV Timecode info would match the HD source tapes if I shoot HD 24p Native to tape?

My guess is that if you wish to shoot HD-tape / DV-card, then you ought to stick with HD 24p over 60i, or 30p over 60i, or just straight up 60i. Yes?

Otherwise my guess is you may have trouble assembling an HD version down the road.

Is my thinking correct here?

I'm asking because I'm doing some quick turn stuff that is only needed Standard Def, but we're toying with 24p (for web and/or embedding into a powerpoint). My understanding is that if you're playing off a computer, then it's good to stay progressive and not mess with the pulldown (24p over 60i for instance).

In order to get a 24p video file to edit in a 23.97 timeline, I'm guessing I'd have to simply run every clip through compressor or another tool - correct?

Just thinking outloud and seeing if there's something I missed.

My other option is to shoot 30p and not worry about pulldown etc...

BY THE WAY... is there any difference in the HDV 30p Mode found in the Progressive menu and 30p found in the Interlaced menu?

Welcome to DV Info. I read your post many times and find it confusing.

23.98 (23.976) cannot exist on tape which is not HD-CAM SR or D5*. Otherwise, it is over 60i as you say. If you final output is web - don't worry about pulldown either way. Pulldown comes into play when you film out (telecine video back to film) or make composites for VFX or need your content to live on HD-CAM SR or D5. For web, anything goes. Any frame rate will display on a TRT / LCD / VGA monitor. Any format will display, NTSC, PAL, SECAM. Don't trouble yourself with progressive and shoot in 24 p normal (inside 60i), don't deinterlace HDV unless you have to (HV20/30 is have to in my book).

Hope this helps,
-C
