Video Production: The Lighting Factor
Yesterday, we were lighting up.
No, not the cigarette kinda lighting up. We rented a bunch of lights and examined the difference it makes in the quality of video. The camera will open up its aperture way more, if lighting is inadequate and degrade the overall quality of the picture. We have used lighting before, but not in the right quantity and positioning.
Our main concerns, were
1. The obtrusiveness of the light mounts to the local audience
2. The correct strength of lights
3. Correct positioning of lights
Here is a video clip from the event showing the video quality as being close to SD television:
2x1000W from the front
2x300W on the head/shoulders from the back
The other feature was the use of multiple cameras all positioned together to get wide/closeup shots. Thanks to Dan of Russel Video for the tip, who supplied the lights. This reduces staffing needs, with a multicamera setup. We fired up our good old Tricaster for achieving live editing to broadcast over Mediasite.

A Web of Flyswatters
Yesterday I tried out a configuration of 4 flyswatters (Crown Soundgrabber 2s) in SPH2 Auditorium to see how well instructor and audience audio can be obtained without depending on individual serving mics (lapels, Shure 58s, or wireless avatars which are handed around and passed around).
The idea is to avoid audio-postproduction, which is such a productvity killer and time waster. So here are few samples which includes flyswatter-only audio, mixed live by yours truly. The mic positions in the SPH2 Auditorium is indicated:
Interaction with a student on the east side of the auditorium:
Interaction with a student on the center column of the auditorium:

Password Protecting Podcasts
I was able to password protect individual podcast mp3s using simple directory authentication on my personal server. Now I have to try that with Kerberos cosign.
