HVX-200 Blue Screen Test Footage at DVinfo.net

Cassidy Bisher · April 5th, 2006, 08:13 AM

Hey all, we weren't aiming for perfection here. I used an old blue screen, it had a lot of wrinkles. We did try and light it well though making sure that the subject had a well defined outline. And when we turned off the keylight on the subject, she was perfectly silhouetted. It's known that there should not be small parts of the clothing, hair or even hair hanging loose as you want a sharp separation from the background. But we chose not to. We chose to try and key out wet hair being thrashed around to see how well the HVX did. Well, I think it did great!

Foundry's keylight was used to pull the matte.

Very good keying. Very good camera for Indies.

That is crazy! How did you do the water?

Looks amazing, what are the camera settings and how did you key it? This has to be an Ultimatte or some serious plugin.
All of the footage that you have posted for this camera is incredible but this takes the cake.

Well we used Foundry's Keylight in After Effects.

I don't think the camera settings really mattered, but it was shot in 60p. And there was NOT a lot of work, i just selected the blue that I wanted to pull from the matte, a few settings were tweaked like screen strength and what not, and since spill supression is built right into keylight I didn't have to worry about that. Since we lit her seperately there wasn't a lot of spill to begin with.

The water in my opinion could have been better, I could have put a lot of time in to it, but it was a test... Keylight pulled the blue through the glass and kept the reflections.

All in all this yielded very clean results...

Wow, I'm impressed!

WHOA. Nice work guys!!

Barlow Elton · April 5th, 2006, 01:55 PM

Very nice! Did you shoot DVCproHD 720 or SD DV50?

Good work, man. btw, love the Finding Nemo music track with it.

Thanks... we shot 720p60 DVCPRO100, you can tell it's overcranked, you can't shoot SD overcranked... plus keying in DV has never yielded very good results, so i probably wouldn't try it.. with HD there is more color information there and the matte is easier to pull.

Barlow Elton · April 5th, 2006, 02:46 PM

Duh, the slow mo would be a slight hint there. My bad. I guess because you posted an SD sized clip my thinking was you might have tried DV50 for it's milder compression. So it keys well in 720p? Awesome. My experience even with HDV is that keying is much better in the high def formats.

Again, thanks for the excellent examples.

Excellent work. I especially like the bar scene because the reflection on the bar "sells" the shot. The average person wouldn't even think it's a composite.

One tip though -- the reflection should be flipped 180-degrees from vertical, not angled based on the diagonal perspective of the bar in this view. (Consider that anything sitting on the bar, which we assume should be level, would also be 100% vertical, not angled.)

Thanks, yea I know, it's trick i do in photoshop a lot... I just got lazy.

Well, I suppose that the HVX200 so far seems to be the camera to beat for chroma keying in the <$10,000 range. Now, let me pick my jaw up off the floor because that was great for me since I plan to do a lot of green screen work. =)

Hi - Great work Sir

How did you do the last scence with the bar shot .This is very clever stuff I noticed that you even had reflections of the girl on the bar .

How did you get the virtual bar set ? would this be serious magigs ultra communicator ? I am curious because I am intrested in using virtual sets my self .

Thanks for sharing your work - Alfred

It's just a simple composite, with a few mattes on the lower part of her body. And this isn't a virtual set, it's a picture off of the internet, If i were to build a set it would be done in Maya. Anyway I'm glad you liked it.

I just showed the clip to our keying specialist who basically spends hours shooting key every day. It took at least 60-seconds for him to turn around and look at me with a grin saying "you got me, it's a key job." For sixty seconds he had not realised it. Then I told him it was an HVX and not a Varicam and without a beat turned around, popped open his Firefox and logged into B&H. Geez, I wonder why.
