LIVE Cameras video on a big LEDWALL
on Apr 13, 2011 at 9:25:48 pm

Hi there,
it's my first post here, but it's long time I see this amazing site!

Next month I have to make event with live video to be projected on a ledwall. It's my first work with a ledwall.

I think the common basic setup will be: 2 cameras, 1 mixer-video then monitors and all.

For a sort of "low budget solution" do you think that two Panasonic DVX-100 with out crappy composite signal could OK or I need for sure some signal SDI or HD-SDI for best quality and then going to HPX-500? Usually what kind of signals accepts a "big screen" like that? We need to record the mix. On which support it could be ok?

Sorry for the confusion, but I'd be so happy if someone could explain me better this workflow for his own experience.

Thanks in advance!
BYE!

I'm doing pretty much the same thing today, the video walls I'm feeding are 10mm, around 9' x 12' each. The resolution on video walls is pretty low, you don't need to be feeding hi resolution. I'd say composite would be OK, but if you are recording the event (which I do, even if the client doesn't ask) better to keep that part of the chain higher resolution. The walls I'm using will accept just about any input, in my case I will be feeding them 1024 x 768.

Thanks man for your reply!

So if composite would be ok and the client doesn't want to spend lots of money do you could I use two Cameras like Panasonic HPX-171 and Mixer-Video like the old but good MX-50?
What hardware are you using? And where are you recording to? I think I'll rec the program to a PC going to it via a Firewire acquisition device and as a backup a DVD-recorder...
But how to set the resoultion if I'm using an "analogic" composite signal? I don't think it's my case...

Because the resolution isn't too important, and the client has no budget, here's my set up:
2 - D50 cameras studio configured, composite from CCU into a Sony Anycast. The Anycast has Firewire and external hard drives, these will be recording the cameras. From the Anycast to a ScreenPro, Magenta Research (Cat5/ VGA balun) boxes to video wall(s). I'm using the ScreenPro because I have more sources, Playback Pro, two PowerPoint computers and a back-up DVD player.
MX-50 would work, maybe a composite D/A to feed the MX-50 output to the recorder/ monitor/ wall.
Composite is composite, no settings required. You just need to verify the inputs required for the record interface card and video wall, hopefully they support composite.

I see man you got a nice setup.
Maybe as you use the ScreenPro we'll use Watchout 'cause we too have some graphics to show.
But another supporto to rec in HQ? Which could it be?

What do you mean with "composite D/A to feed the MX-50 output to the recorder/ monitor/ wall"?

The set up could be much nicer, if I could find some clients that would spend some money.

The MX-50 has either composite video (comp) or s-video (Y/C) out. You only have 2 outs and 3 things to feed. 1. Program monitor, 2. Recorder, 3. Video wall. You could loop the program monitor, if it has an in/out, but I prefer a separate feed for each item. Every time you loop something there is a bit of line loss and going composite you need all the signal you can get.

Of course, the chain will change if you want to record in a higher resolution, you'll need a better switcher to start with.

Yes, mine setup too could be much better if the client...

Anyway it's not a problem for the # of outputs I need 'cause I'll use a Composite Video Splitter!

Thanks man for your support,
I'll tell you what's going on with this project!

Bye!
