XL H1 24p questions

Posted by James Carl on April 11, 2006 at 5:52 pm

From what I am reading it sure seems that the H1 is HOT. What bothers me, if I am understanding correctly is that in the 24p mode, the vertical resolution drops. Is this true?

I also so far have not been able to find out if the H1 does advanced 2:3:3:2 pull down or just 2:3??

I currently have a Sony Z1 and not being able to do 24p that is usable has caused tons of grief for me.
It seems that even though the JVC and Panasonic cameras do 24P they have smaller ccds and give an uprezed sort of look.

I tried using some of the conversion software to go to 24P from my 60i Z1 footage and it didn’t look so good. I actually liked the line doubled frames better even though I lost 1/2 my resolution.

My dilema is that I’ll stick with the Z1 until we have a really good 24p solution that is a signufucant step up.

1)Vertical Resolution does drop in 24F HDV. Still seems sharper than Sony, JVC or Panasonic
2) Pull down can be either 2:3 or 2:3:3:2 in DV. Menu setting. HDV is 24F, 30F or 60i so there is no pull down recorded. Not sure which one gets added to NTSC playback in HDV.
3) JVC and Pansonic have same size CCD’s just fewer active pixel elements
4) The Canon HDV 24F is very useable but you need to use the camera to play it back if it is on tape. If you are recording the camera live from SDI to disc then you have a different workflow

Expect you will want to buy a new lens and viewfinder to use the XLH1 to its full potential. Since these haven’t been released yet it is a bit of a gamble as to when the system will reach its potential. Maybe we will know more of a timetable at NAB

Thanks Daniel,

Still trying to understand why the vertical resloution would drop unless it is line dubling half fields?

NAB hopefully will have some new announcements in the lens dept.

I don’t believe it’s simly line-doubling fields. It wouldn’t look as good as it does. I believe it’s doing some kind of motion-adaptive interpolation of *possibly* 48i, and that’s why it looks great. It could be some other method of progressive interpolation, but Canon has no inclination to reveal their recipe.

I have an example of 24F edited with FCP over here. https://xlcinema.com/viewtopic.php?t=28
