Yeah, that could well be. I think that GTW’s claim of “HD” is BS. Here’s what Support shared with me yesterday:
Anyone with an Internet connection and a webcam can use HDFaces in GoToMeeting sessions. You can start sharing video with a single click; our Multistream HD technology provides up to 6 video streams at a resolution of 640p x 480p each, for a total maximum resolution of 1920p x 960p.Here’s what I replied:
So up to six cameras… OK, but if I’m using one camera, does that mean it’s at 1920x960? And I can’t even imagine why that odd resolution… but OK… so if I have ONE camera, is it 1920x960, or is it 640x480 scaled up to 1920x960? Incidentally, 640x480 is a 4:3 ratio (and not even marginally HD; that’s SD through and through), and 1920x960 is a 2:1 ratio, while actual HD is 1920x1080, a 16:9 ratio. I’m so confused.Their technical explanation really doesn’t make any sense to me, but it does tell me that they are NOT actually taking in a 1920x1080 feed. After comparing aspect ratios and how bad a computer screen shared through the ATEM looks once it’s on GTW, here’s my working theory: It appears they are center punching 4:3 crop of the image, possibly scaling that down to 640x480, cropping that for 16:9, then scaling that up to 1920x960, but only using a piece of it. I mean that sounds utterly ridiculous but nothing else adds up.
Sadly what this ultimately means, I think, is that I can NOT use the ATEM to switch between a camera and a screen, which was my intention. Their screen sharing is soft, but this scaling is way softer. I wanted to go full screen between camera and computer, not have their side-by-side view, but I don’t think that’s going to be possible now. Lame.
