This is my first post here, so first of all, hello everybody.
Now to my question. I record our church services in a fairly low-tech manner. I record to a hard drive by running the DV out through firewire into a laptop running WinDV. Yesterday our administrative pastor asked if there was a way of splitting the signal so that we could provide a live feed to a couple of screens in the foyer. We are only using a consumer-grade Sony camcorder (I cannot remember the model but it is a couple of years old.) Is something like this possible, or is there some type of hardware that we could buy, or should we just wait until we can upgrade our entire production arrangement? TIA.
I don’t recall the camera model number. But we record the sound through the 1/8" AV port. This is the port that you would normally use to connect to a TV (1/8" to RCA cable required). It’s a bidirectional port. We convert 1/4" output from the mixer down to 1/8" and put it in there. (It does not bypass the onboard mic though, so what we get is actually a combination of the mixer and the camera mic – we have to be really quiet.)
The easiest way would be to connect the av cable (usually a three ringed mini jack, with three rca plugs on a short cable) for your camcorder to the camcorder, then run the audio/video (rca jacks) to a vcr, then a splitter from the vcr to 2 screens. (you could run without the vcr if it is for a short distance with just a y splitter on each rca jack, but why not have the vcr to record a back up?).
The dificulty with that (and I should have mentioned it in my original post) is that the AV out is also the audio-in from a small mixer that we use for the sound. I am thinking we need a different camera at least.
if you were using a Mac I’d suggest using quartz composer, and a video out adapter….using the video out as a second monitor, a couple patches with QC and you got a second feed with the ability to genlock titles and apply video effects to a live video feed.
don’t know a thing about what to do with windoze though.
If your Sony camcorder also has a D/V in out on it like my Digital 8 does, I plug the D/V in out cord into my camcorder, on the other end of the cord you should have red audio, white audio, and yellow video RCA Plugs.
I would run these into the IN jacks on the back of a VHS VCR make sure that your VCR is tuned to the correct channel or line in function every VCR is different some have LINE IN or some other way to activate this function. from there you can run a coaxial cable from the back of your VCR to a Splitter and go to your TV sets. If I use Screens or devices that don’t have a coaxial cable input( like a video projector), I hook my coaxial cable back into a VCR( What this does is hooks two VCRs together one on each end of the coaxial cable) then I run RCA cables from my VCR out jacks to my video screen. Kinda low tech too but it works. You just have to make sure all of your line in, line outs, and channels are correct. I use this at our church and I run the coaxial cable over 500 feet between VCRs. One trick I found when activating the VCR next to my camera I just put a tape in the VCR and push play it will activate your coaxial out on your VCR to the VCR on the other end as long that VCR is on Channel 3 then your line out RCA jacks should work to your Screen inputs.
You can eliminate the VCRs by going to Big Lots or Radio Shack probably has them too, they make
a video convertor that coverts coaxial inputs to RCA outputs for monitors that don’t have coaxial cable input output.
