24P and 24F comparison clip

Hey all,

So I went to B&H today to do some comparisons between the 24P on the XL2 and the 24F on the XL-H1. My main concern before purchasing the XL-H1 was its 24F performance. Well I can tell you that 24F performs every bit as good as 24P. The motion rendition seems to be exactly the same. I recorded a fast pan with both cameras and placed the footage side by side in Final Cut Pro and exported out a quick clip for you all to see. You can analyze it frame by frame and see how 24F seems to emulate 24P footage extremely well. Even down to the motion blur, it seems equal ...

Hope this helps in the whole 24F motion rendition confusion. It may not capture progressively, but whatever the Digic DVII chip is doing, it sure outputs as if it was progressive. In DV, you even have the same 2:3 and 2:3:3:2 pulldown options. Check it out for yourself and you be the judge.

One note: These clips were both shot in normal 2:3 pulldown mode ... I should've done 2:3:3:2 to be able to create a true 23.98 file, but this should demonstrate the motion just fine.

Let me know what you think.
 
I have had the exact same experience.... NOTHING like the Sony version, at least in final image. Probably takes a rez hit but still looks equal to, if not moreso, the rez of the HVX200...

The motion rendition appears to be exactly the same. In horizontal resolution the XLH1 is higher. In vertical resolution they seem very similar.
 
Barry,

How well do you think the H1 and HVX might intercut? My personal belief is that they would both perform best together in a 720p timeline.
 
Galvan,

No doubt about it, they are the same. I think 24F in SD from the H1 probably doesn't deinterlace, so it probably IS literally the same.

Thanks for posting. Very helpful.

No problem man .. thanks to all of you for all the info you provide ... it is certainly helping me in my decisions. As of now, I believe I will indeed go with the XL-H1 over the HVX.

Why would you say that 24F in SD from the H1 probably doesn't deinterlace? It's output is coming from interlaced chips ... I would think that 24F done in SD and HD on that camera is done in the same way ...

How do you know? Those images aren't full-res images... and neither is an HVX200 (even though it's on the HVX Forum)...
 
I have access to both cameras and have fooled with them myself... I agree with Barry, I think I can get them to cut together well.

First off, I generally hate tests, especially technical ones. I will soon be shooting some footage via HD-SDI out into an HD1200A deck to check how that looks. I hope to use the XLH as my lockdown camera and the HVX as my field camera in several upcoming projects.
