i use AVS through a vision mixer at FOX STUDIOS fortnightly during one of the nights there.
I only use/edit/make bright presets as too much black in the background doesnt look good at all.. looks very empty.
I like AVS to use the whole screen, with many colours. Rendering the FOX logo and Promoters logos are very common for me, again have learnt which presets are best used for overlaying + making sure of 30fps, which is minimum.
I use 640 X 480 with Pixel doubling on and only use presets which look good in this mode.
havnt taken any pics yet of the screen, although ive cammed many of the nights there including BARDOTs live performance there 2 weeks ago
