Hi,
Has anyone done this with 3 LFG4's? Which macpro? Would it be possible to share those experiences?
Thanks,

Hi guys,
For the moment we decided to go with 1 LFG4 and a composite switcher. The switchers needs to be programmed on the desk.
Any suggestions on a reliable usb-serial adaptor? Switchers will be kramer, extron or tvone.
Has anyone worked with the kissboxes, http://www.kissbox.nl/products_new.html#serial?
Thanks,
Peter
Never worked with their serial one, but I've used their MIDI boxes a few times.Quote:

I have done 12 inputs via 3 LFG4 cards. It is possible. I would recommend using a 2008 mac pro for this with an 8800 GPU.
If you are trying to switch 10 cameras though, wouldn't you have a TD running their own switcher? Wouldn't it make more sense to take a second ME from the main switcher and feed it into a single input than to have a second switcher just for Catalyst? Or is this pre Cat Switcher the only one?
The pre Cat is the only one. It's work in progress, so it can change. We're looking at a lot of possibilities. The idea is to use just 1 switcher: 10 in (using only 7), 2 out. The 2 outputs would give us the possibility to crossfade between 2 choosen camera's or to have a split screen. These would be on LFG4 input 1 and 2. On 3 and 4 there will be camera's for the 2 singers. Does this makes sense?Quote:

What about 2 LFG4's in a macpro 1.1? I will test if I have the change.
Best practices I've seen are to have the switcher do all of the crossfading. Therefore, your first two inputs could be scaled down to one. The idea is that pushing a T-bar is easier to preview than building a crossfade cue between two input layers.Quote:

Don't overcomplicate things. The having one system to manage inputs (IE switcher) is smarter than having two or more (switcher and Catalyst performing same tasks).Quote:

In this manner 99% of the show is through input 1 from the switcher. Only 1% of the show is where I end up displaying multiple cameras simultaneously as a fixed cue. (this usually ends up being less than 10 total shots of the show) All camera guys are briefed on the specific shots and for those shots only, the Catalyst has uses all the individual inputs).
This is a judgement call of your video engineer. Without knowing more details of the system I cannot recommend or suggest what you do and don't need. I can however place you in touch with plenty of industry experts that can help to consult your project should you feel this is too complex.Quote:

In a common situation though 20m is fine for good quality BNC cable. The specification supports lengths up to 100m.
I have never personally put 3 LFG4s in a MacPro 1.1 (2006) but I have done 2 without problems.Quote:
