HVX200 vs XL-H1 Highlight Blowout Analysis

David Newman · January 29th, 2006, 06:35 PM

I figured FCP was used for DVCPRO-HD, I just didn't expect it to be broken for HDV handling (another reason not to edit native :) .) I guess we will wait for Steev to confirm. If FCP is clipping Luma in HDV, and not DVCPRO-HD that as a real puzzler, certainly a screw-up somewhere.

It was probably rendered in FCP without checking "super white" in the settings.

Barlow, thanks that would explain things.

Ash, It is not just camera setup as there is clearly an error in post.

Hey don't forget Canopus who was the first to use a YUV plugin to Ppro....Edius handles super whites and blacks just fine.

Seems like super White should be the default since so many if not most DV and HDV record up to 108IRE. I'd like to see the test repeated with both camera and NLE set correctly.

To clarify, my findings of HDV having less latitude than DVCPRO HD is not conclusive and I don't stand by it. So scratch that.

What I do stand by is that the raw footage I have with any blown highlights of the HVX200, rival the XL-H1 with blown highlights when trying to correct the problem in post.

I think I know what the answer is based on people's responses. There is a lot to be said about setting the knee to low on the XL. I always had the knee set to low and blacks stretched on my XL2 and I loved the way it handled everything.

Trying my test with Barlow's snow footage resulted in similar highlight control in post as the HVX200. So officially we can axe this thread except for perhaps the emphasis on the importance of setting the knee to low on the XL.

Agreed?

Yes, set the knee to low and make sure you have your LCD calibrated if you are not using an external monitor. Today I shot with the $3500 Panny HD-SDI in monitor with the XLH... WOW... stunning... HD-SDI is NOT just for record out, it is GREAT for monitoring.

Ash,

Is this the brand new one from Panny, vector and wave built in... if so that's good to know...

Maybe when I get back to Springfield... us MO's and you Tuslan's who are in film and video should get together...

Tulsa's just a few hour drive... plus all my dad's folks are there... like I tell my cousin its takes me the same amount of time to drive to LA from the OC... except I'm moving the whole time..

But I can't leave until the end of March starting on a film here... actually I'll be in Tulsa on Sunday just driving my sister back to Missouri... the whole clan is getting out of high rent California...

Ash Greyson · January 31st, 2006, 05:39 PM

Sounds good, just let me know... it was the Panny 1700W monitor....
