JCoster Posted February 24, 2005 Share Posted February 24, 2005 Hi. At the next Battle of the Bands we plan to project live video from many different sources such as fully op'ed cameras and podded ones like at proper gigs. Getting the inputs from the cameras to a computer is no problem as such, however, we don't know what the best piece of software to use would be. We need to be able to change video sources in full-screen mode and possibly use transition effects in-between the change of video sources as well as possible text lay-overs. Any help would be greatly appreciated. --James Costerjames.coster@gmail.com Link to comment Share on other sites More sharing options...
James Posted February 24, 2005 Share Posted February 24, 2005 James. I don't see why you want to bring your cameras to a computer. It would make more sense to bring them to a vision mixer. I assume that you don't have professional cameras so you need a genlocked vision mixer with a TBC on each chanel or ME bus. For Transition effects you would need some form of DVE, again there are simple DVEs built into domestic vision mixers. The quality isn't brilliant but it will do the job, For compositing text you will need a source of text and a keyer. Some vision mixers also have keyers built in. If you want to have the text on the output of the mixer and not do anything funky with it a dsk (down stream keyer) or external keyer will work fine, If you want to do funky stuff with the keyed text then you need to find a mixer with a key on an ME bus. Hope this helps. If you realy want to do funy stuff with the video then have a look at a Snell & Wilcox Magic DaVE you can get these to accept non sync sources and it has some great DVE effects. (although the buttons are a little small IMHO) James James Link to comment Share on other sites More sharing options...
JCoster Posted February 24, 2005 Author Share Posted February 24, 2005 James, thank you for your reply, however, our budget won't stretch as far as a vision mixer. This is why it would be easier for us to use a computer, unless you know anywhere that vision mixers are going cheap! Is there anywhere you know of that does a software vision mixer or some kind of multiple video input server? Link to comment Share on other sites More sharing options...
Pete McCrea Posted February 24, 2005 Share Posted February 24, 2005 What is your budget? Surely adding the relevant cards to a PC will cost as much as hire of an MX50 or something. Personally I'd not trust video mixing to a PC. There's always the potential to crash. There's likely to be a company with hire stock near you.

JCoster Posted February 24, 2005 Author Share Posted February 24, 2005 We have all the PCI cards already, with S-Video in sockets, just we need cheap or free software, for example a free version of ArKaos. Link to comment Share on other sites More sharing options...

Their website is here: Unicol [Pedant] Don't you mean NIC not NEC? As in, Network Interface Card. :P [/Pedant] Don't knock floppy drives, they are extremely useful for bootdisks, as well as making things such as 'password reset disks' (although I hate this particular idea).

JCoster Posted February 25, 2005 Author Share Posted February 25, 2005 Typo fixed... And yeah, ummm... I'm not sure if I agree with your opinion on floppy drives... Just remember your password! Thanks for the information- greatly appreciated. Link to comment Share on other sites More sharing options...

Their website is here: Unicol <{POST_SNAPBACK}> Good stuff, all of it, but boy does it cost! However, you can get good discounts for schools etc. (I use Kingston Supplies, 0208 3302446) They will make a custom plate for you projector if they don't have a stock item. You then add standard poles etc. It also maker regular ebay appearances, but watch the shipping costs, and you are unlikey to get plates for modern LCDs yet.

JCoster Posted February 26, 2005 Author Share Posted February 26, 2005 Does anyone have any Unicol stuff that we could borrow for a month or so? Link to comment Share on other sites More sharing options...
TomLyall Posted February 26, 2005 Share Posted February 26, 2005 There are a number of hire companies who stock unicol, although unless you can find one with the same projectors you may have to buy the plates yourself. Have you bought the projectors? It might be worth investing in some of the unicol stuff if you plan to use them like this again. Does anyone know if you may use normal ali or scaff bar with unicol fittings? (I mean, are you allowed to, not can you) Link to comment Share on other sites More sharing options...
JCoster Posted February 26, 2005 Author Share Posted February 26, 2005 Ummm... It's kind of a loan rent thing for free... I have connections . Ok, but we want a cheap solution as we wouldn't be getting paid too much for the gig anyway, so borrowing would be better again. Link to comment Share on other sites More sharing options...
lonfire Posted March 2, 2005 Share Posted March 2, 2005 hi,I bourght a couple of cheap uniersal projector mounts off ebay for 30 quid each and fitted two G clamps to them.. then made sure the whole thing had a couple of safety chains on it.. seems to be pretty secure and worked well.. but not as secure as a unicol fitting.. rgdschris Link to comment Share on other sites More sharing options...
JCoster Posted March 4, 2005 Author Share Posted March 4, 2005 Ok, thanks. I'll look on eBay later. Link to comment Share on other sites More sharing options...
ChrisD Posted March 6, 2005 Share Posted March 6, 2005 I've got limited experience with such things,but won't you get a significant time delay by using a pc rather than an MX50 or a Dave? Link to comment Share on other sites More sharing options...
