Webcast color

Postby craiggsmith » Mon Nov 03, 2014 8:34 am

I've asked about this before but never got a definitive answer. The picture at the receiving ends has very little color. It seems to be on the church's end, I assume due to the compression, as I monitor the signal right before it goes into the communicator and it has plenty of color. Is it the same for everyone? Any way to improve that? I've tried the highest bandwidth the device allows (750 kbps) and it doesn't improve it at all. In fact, I don't really notice any changes in the video with any setting, only with the audio.

How are you feeding it? Composite video has a defined amplitude. Long cable runs result in attenuation of the signal. Different devices deal with that in different ways. Intermediate devices (like mixers), may or may not reset the amplitude.

You might try doing a test stream from a "Fresh source" (like a non-copy protected DVD) sitting right next to the communicator.

Cable goes about 15 ft from the camera to the jack in the wall in the overflow, and then back to the VDA in the a/v rack (~100 ft over coax) and then to the communicator (in the a/v rack). I tried a VDA between the camera and wall jack but it didn't help. I've monitored the signal at the rack though and it looked fine.

Good idea to try another source. I'll also try the camera connected directly to the communicator, and try s-video (I think that's an option).
