HV20 HDV to DV

[monster_zero]

Does anyone know if the HV20 can record in HDV and then upload video as standard DV? Or could the HDV on the tape possibly be played through an old mini DV camcorder and captured as standard DV?

[Barry_Green]

No, and no. I don't believe the HV20 has any way to downconvert to DV tape, and no DV camcorder can or will ever be able to play an HDV tape.

this might work.

connect your HV20 to a DV camcorder via video out to Video in. then connect the DV camcorder to you computer via firewire. then do a live capture. you'll lose your time code but it SHOULD work.

Thanks guys. I realize this all sounds kind of superfluous when you could just shoot in mini DV instead of HDV before capturing, but I was just wondering.

Ooh, I was totally wrong -- the HV20 *can* downconvert from HDV to DV on the fly. So you can capture footage into your computer and it'll convert the HDV footage on tape to DV before outputting it through its firewire port. Might be exactly what you need.

Good to know. That sounds about right.

Yes the manual on page 43 under the DV OUTPUT option states:

You can select the video standard to use when connecting to an external device using the HDV/DV terminal.

HDV/DV: Switch automatically between standards to match the original standard of the recordings.

DV LOCKED: All video output will be in DV standard (recordings made in HDV wil be down-converted).

PS: My first post! :)

Hey Barry, so if this is the case does that mean i can remove the pulldown since it's DV and not HDV? or am i still missin the big picture on this subject (still learning, sorry) :dankk2:

[Barry_Green]

Vegas or Cinema Tools should be able to strip the 2:3 pulldown out of downconverted DV, yes. They just don't have support to do that in HDV yet.

if i down converted the video i should be able to do the pull down for the hv20 in vegas 6 just fine with out having vegas 7 is that correct barry ??????

peace n luv

I believe so, yes. Just go to the DV file, right-click, bring up "file format properties", and tell it to remove 2:3 pulldown. Although you'll probably have to take a few stabs at entering a value before you get the "right" cadence; in the text box you can enter 0, 1, 2, 3, or 4. Keep trying until you get one that's completely perfectly in cadence with your footage.

cadence ?????????? explain what you mean by cadence barry please im dumb on this but id rather ask then stay ignoorrant i always say lol

peace n luv

2:3 pulldown transfers each even frame to two fields of video, and each odd frame to three fields of video. So over the course of five "frames" of video, there are five potential patterns (which we will illustrate by using "W" for "whole frames" and "S" for "split frames"):

WWSSW
WSSWW
SSWWW
SWWWS
WWWSS

The cadence has to do with where the 2:3 pulldown sequence starts within a group of five "video frames". Vegas allows you (well, requires you) to enter a value of 0 to 4, to specify how it treats the fields and reconstitutes frames. You have to try each one until you find the proper setting that yields complete full progressive frames with no interlacing.
