Behind The Scenes At VUC561 With Grandstream

gvc3200-right-300#VUC561 about the Grandstream GVC3200 was yet another example of bringing my broadcast video production background into the realm of vodcasting. In the pre-call walk-through Randy took a screen-shot of what he was seeing. It seemed a little busy. There was certainly a lot to look at.

Just for fun I thought I’d make note of what was actually there, and how it was being used.

So that was the inventory, but how was it used? vMix HD software on the desktop handles video switching and compositing. It had the following sources available in this case:

VUC561 Shots
VUC561-Shot23The VUC opening sequence & Phil’s slides loaded as vMix internal source. I especially like how vMix can load a PowerPoint slide set as a single item, then transition seamlessly between slides. It doesn't support effects within a slide, but it's still pretty slick.

This saves me from exporting the slides as images file, then loading them on-at-a-time.

The resulting image quality is very good.

At various points during the call this showed the GVC3200 menus in action, as well as a video call ongoing with Randy's VVX & Bria on my mobile phone.

Since Hangouts operate at 720p the 1080p output of the GVX3200 was being scaled down by the capture card.

This was my first public use of this new PTZ webcam which is a competitor to Logitech's CC3000e Conference Cam. In this case I used it's PTZ presets to switch between several different shots.

I expect to have more to say about this camera soon.

I plan to share the details of how I handle audio, splitting it between two computers to ensure quality. Also, some of the things I’ve done to adapt the Rebel Desk adjustable desk to my working habits.
