About to switch to an HVX. A few questions.

[Brandon Rice]

Hey everyone. It looks like within the next few weeks I'll be upgrading to an HVX. I have several questions however.

The main reason for this switch is because we're producing a kid's show pilot episode, shot entirely on green screen (except for the intro of the show) and I think having an HD product will help in the long run with pitching to networks anyway.

1. Will Avid Xpress Pro HD support 720P 24P?

2. How much storage am I looking at for archiving?

3. Can you cropa 4:3 image from the 16:9 HD image for SD broadcast?

Thanks!

1. Yes, but for keying you'd rather use 1080, and Avid doesn't really have proper 1080/24p support yet.

2. For 720, less than twice as much as DV. For 1080, 4x as much as for DV.

3. Of course.

[Brandon Rice]

Cool, thanks Barry. Now, is 720P still a huge step up from keying out DV? We have had amazing success keying DV, and I really want to stick with Avid right now for our edting solution. Is 720P a big enough step up for keying?

[J.R. Hudson]

Of course it is

[Brandon Rice]

Sweet. I am stoked about this show. Huge Potential!

Yes, 720p is going to be better because you have twice the color resolution. But there's a bit more mosquito noise because DVCPRO-HD uses 6.7:1 compression, vs. DV's 5:1. I'm just saying that for *ultimate* keying, you can do better in 1080 because you still get the 4:2:2, but it's more mildly compressed.

Yes DVCPRO-HD 720p @ 4:2:2 should be substantially, significantly better for keying than DV was.

You've always got the option of going DVCPro50 for keying, given the lower compression ratio - might give you a cleaner key.

Yes I know, it's SD - just throwing out all the options
(and solidifying your choice of an HVX)

:thumbsup:

You didn't wait long, did you Brice?
You trying to keep up with me?

Thanks for the information Barry! I think I'll shoot some tests beforehand, to see exactly what I want to do :thumbsup:

Haha, thanks man! I think we want the HD option :) I do know what you're saying about DVCPro50 though.

I am trying to keep up with you ;) haha! Actually the ONLY reason I am upgrading is for this show we're shooting, and since it's ALL green screen, we need a better option than DV 4.1.1

I'm going out right now to pick up a Genesis - just to one up you.
Good luck with the show.
I'm sure you'll keep us posted.

I'll for sure keep the thread for the show updated! I just love working on stuff all the time! :thumbsup:
