Live Chroma part 2

September 22, 2011

As usual the best laid schemes of Robby Burns etc..etc..

So I didn’t get to start setting up until 3.30 which meant doing a proper comparison of the two software packages wasn’t feasible. I started out with Veescope live, got it up and running and just left it at that. The software was reasonably intuitive, in as much as I found everything I was looking for within a few obvious clicks, and did a pretty good job without having to spend to much time tweaking settings.

So the set up was; Canon MV890 camera feeding a live, standard def, widescreen video feed into our old MacBook. Here Veescope Live did its funky thing, keying out the green background and overlaying the people in front of the camera onto a selection of video backgrounds. We gave visitors the option of appearing in music videos for “Don’t Stop Believing” (the Glee version) and “Firework” by Katy Perry; dancing along with the “Cha Cha Slide” (far and a way the most popular choice) or joining in a light sabre battle. All of this video trickery was then output to the rooms projector on to a screen in front of the ‘actors’. Given the power of the laptop we used I was massively impressed by the way the software coped. There was occasional glitching if there was a lot of fast moving actor and there was a slight, though noticeable, delay between the live action and that on the screen. Overall though the whole shebang went off pretty impressively and seemed to be a hit with those who came along and had a go.

As an aside there was also a great little tool in the software, a vectorscope, which is designed to help light your green-screen.

What it showed was that, even when well lit, a portable, cloth green-screen is always going to be second best to a proper, painted hard surface – negotiations are underway.

The line should be as flat and high up as possible to get the best key
