Thanks - it does well
Thanks Jacky. Please excuse the delay in follow-up processing - I needed to get to my computer at work for some resources.
I have run your test shot through the "Overlay" process in the NLE "ULead Mediastudio Pro 7". Results: 2 x video composites from your footage: (1) against a grey background and (2) against an outdoors landscape. Note: Big download of 14Meg. http://island.manukau.ac.nz/iafilm/t...omposite01.wmv Still image frame grab from the above, says it all in 120KB: http://island.manukau.ac.nz/iafilm/t...omposite01.jpg I too have tried using a monitor as a greenscreen. I find it gives a very even background, but it does act as a green light source to give green edge lighting on the subject. Allowing for that, IMO this is a good result and as good or slightly better than what I get out of Mini-DV cameras using monitors as greenscreens. Here for comparison is one of my tests done with a similar setup, and using a Sony TRV950 Mini-DV camera, a relatively high-end prosumer model.

I did some greenscreen test comp in AfterEffects using Keylight and Composite wizard plugins. Spent about 5minutes and the result is not too bad. At least for clean solid edges greenscreen seems to work reasonalbly well. I couldn't use my favorite blue/greenscreen plugin Primatte, which I might have gotten even cleaner result. It'd be great to see another GS test with some hairy or furry object. You know, like waving a barbie doll in front a greenscreen :) So under right setup, HD1 looks like it would perform much better than 4:1:1 DV compressed -'interlaced'(Yikes) footages. Cheers. Thanks for the test clips. |

Another keytest
I took screengrabs from some of the available footage elsewhere in the forum, using VLC, and composited in AE with keylight.
This was a single color sample with no tweeks at all. There is some compression artifacting on the side windows, but otherwise, I'm very impressed at the quality. Especially since the bluescreen was actually the sky. http://imagine8.biz/keytest.jpg Rob P.S. Note the transparency on one of the windows on the left showing the BG image through it. |
