Advice / suggestion needed!

I've been asked to film a carol service where carol words will be shown on screen and an iPad band will be playing on stage (4 guys using Garageband instruments and to show them from 'over the shoulder' playing) and send my output to screen through a projector.
 
The system in ATM is an iMac with ProPresenter and VGA to a projector. I've done some tests using 2 cameras with composite (also tried S) out through an MX50 then to a DV deck and Firewire out the deck to FW in on the iMac, mixed with words in ProPresenter and sent to the projector via VGA - the picture delay makes it totally unusable.
 
Any suggestions?

All I can say is that I still use an MX50 for live mixes and large "behind the stage" screens, and although there's a delay, it's ok.
 
 I'd guess that your major problem is the iMac's D>A conversion, and back.
 
 I use a MacPro in a studio environment, running HD-SDI through a mixer and a capture card, then back out through the capture card and HD-SDI to HDMi on the floor.
 
 The delay is far too great for the floor to use it  "as live" and I have to revert to the floor monitor showing mixer output, rather than the Mac output.
 
 I guess you need to find some way of getting the mac to output a useable video image and then mix that on the MX.
 
I lent my mixer to a mate and he ran something using a box of tricks from the pc/mac that he bought from Maplin. It was cheapish at £25 and used USB to power a short VGA to composite lead
He said that it looked ok.
 
 Bring back Amigas and Rendale Genlocks.!

Thanks Dave - I think he probably used this http://www.maplin.co.uk/p/pc-to-tv-box-a94ht
 
After I posted I thought I might be thinking this the wrong way round - perhaps take their VGA and add it to my MX50 keyed.  The problem I'm up against is this church has no idea of using video - the projector screen is still 4:3 and they have no budget (it's an inverse budget job for me!). they don't even want it actually filmed just thrown to screen.
 
I've got the ProPresenter demo on my Mac so might have a play going 'the other way" later today, at the price I might even get the Maplin box for future use!

It was similar, but more like a matchbox with several leads in and out. (from memory)
 
Maplin never seem to sell the same thing for more than 2 years
 
The write up doesn't seem too good but people's expectations are unknown. I have a 40" Toshiba that has VGA in but limited in what it does.
if people expect super high definition by using a box to give composite to a telly, then more fool them.
 
 I'd try to get it and play with it if I was you, as it might be sensitive to certain colours/ thickness of detail.

I've ordered a s/h pro scan converter from eBay - £20, just hope it gets here in time - seller had stuck it in >Enterprise Networking, Servers>Other Enterprise Networking!
 
Did come across a nifty (tech term) bit of cheap kit - http://www.ebay.co.uk/itm/190669852012 - £13, takes a video feed and converts it to VGA, useless in composite mode but 90% reasonable in "S", means I can now feed the MX50 preview to an old 14" LCD I have knocking around rather than an older, bulkier Sony portable video monitor.

I have a Kramer composite (only I think) to VGA or higher box somewhere I think. Don't think it's bi directional
 
I used to use a quad splitter with my MX that accepted composite and put out composite/vga . It made for an easy monitor pack, but was fiddly so I upgraded to 4 x small LCDs when they became cheaper.
 
The quad was good but the output on VGA was nowhere near as good as on composite. At the point I bought it, 17" PC monitors were far cheaper than the same size TV's. I eventually got a "proline" from comet for £50

Update, (mainly for Dave M) - Scan converter from eBay turned up - all lit up OK but no output so sending it back to seller.  Went into Maplins, spoke to sales guy who said he had one of the PC to TV converters they were selling at £27, I explained what I needed it for and was told I could take it back if it didn't look OK. Just tested it with a Mac / ProPresenter and the MX50 and was pleasantly surprised so I'm going to keep it and use it on Sunday (tech run through on Saturday so fingers crossed!). Link to converter in post above if anyone else is interested.

Hope it goes well Dave,
 
 The job may not be state of the art, but nobody can afford to turn stuff like this down these days, and some of the scan converter solutions cost thousands!
 
 My mate did his with scoreboards from a computer, paying attention to fonts helped the image, probably stay away from reds as well?
 
cheers
