bob.darby Posted July 26, 2009 Share Posted July 26, 2009 I work with a large church that uses a Extron 8x8 matrix switch to feed a mix of camera's, DVD, powerpoint, other PC video applications, etc onto main projection screens and additional monitors around the site. The problem is that the switch does not support seemless transition so we loose image for up to 4 seconds while devices re-sync etc - not a good viewing experience! The requirements is for min 8x4 (ideally 8x8) multi-format, seemless/smooth switching with simple fade/wipe etc, that can be used by non-experts. I have seached the forum, and the suppliers. I can find plenty 8x1 or 8x2, either switches or vision mixers. I am struggling with 8x4 or 8x8. Any advce or pointers in the right direction would be welcome.

DanHerbert Posted July 26, 2009 Share Posted July 26, 2009 I'm guessing you've tried Kramer Electronics and Sierra Video? I know that most of these come as standard 8 x8 expandable... Link to comment Share on other sites More sharing options...

Yup - the Kramer , Sierra Video and others are not seamless (at 8x8 etc). Thy do seamless at 8x1 and 8x2. I'm thinking I may end up stacking 4 seamless 8x1s together, and then driving the lot from a PC. Link to comment Share on other sites More sharing options...
FullRange Posted July 26, 2009 Share Posted July 26, 2009 There are some available from AMX (see here for their fully modular option). But this will only work with all of your sources genlocked. I suspect this is not possible in your case?There is an 8x8 RGBHV seamless matrix from Kramer here. But do you need universal inputs and/or scalers? Well, anyway it might work depending on your setup. Link to comment Share on other sites More sharing options...
Matt Riley Posted July 26, 2009 Share Posted July 26, 2009 How about just cascading 2 or more pro units, for instance the barco screenpro II? Having said that, what I'd probably do if I were you, would be to run the main screens as true seamless through a screenpro 2 and then use the matrix switcher alongside that for the less key screens (ie breakout rooms and visual feedback monitors etc). I'm also struggling to see how in your application you need quite that many unique mixes of sources though? Link to comment Share on other sites More sharing options...
lobba Posted July 26, 2009 Share Posted July 26, 2009 What's your budget, have you considered a Spyder? It's one of the few things that will give you that number of outputs and a lot more.... Lobba Link to comment Share on other sites More sharing options...
kitlane Posted July 27, 2009 Share Posted July 27, 2009 Do you really need 8 unique output mixes simultaneously? Perhaps what you need is a production switcher (Mixer) with 8 inputs and a distribution amplifier to feed the output to several locations. If you do need some different outputs (e.g. an information display at the main entrance) then the 8x8 matrix can still be used - for some applications the sync delay is not critical. Do you show live images of the person speaking onstage? If you don't have genlocked cameras then the signals will have to be synchronised by a time-base corrector. This will introduce a delay of at least 40ms (probably more) which is enough for the projected image and live person(including their amplified speech) to be out of sync which is very annoying. If the input signals aren't synchronised in some way then a fade or wipe will be a mess. Link to comment Share on other sites More sharing options...
ItayGal Posted July 27, 2009 Share Posted July 27, 2009 If you're church have some spare cash you can have a look on the new vista spyder X20 they have an 8X8 modelor the URS matrix which also can scale and mix. http://www.christiedigital.com/AMEN/Produc...ieSpyderX20.htmhttp://www.vistasystems.net/what_is_urs/index.asp but probably stacking 4 kramer (or other) seamless switchers will be cheaper.

bob.darby Posted July 27, 2009 Author Share Posted July 27, 2009 All - thanks for the useful feedback. Why 8 different outputs - well we use 4 actively today that are often all different (main projection, side projection, foldback for stage, preview in the gallery) and given we need? to move up a notch then having some headroom would seem sensible. However, the comments around re-visiting the requirements are well made. We could probably cope fine with seamless on the main projection (or main & sides) and less capability on the rest. It would be a lot cheaper! I had not seen the Spyder X20. From a quick read it looks great. No prices though, I'll need to call up my friendly Christie guy and ask. Thanks Again Link to comment Share on other sites More sharing options...
Pete McCrea Posted July 27, 2009 Share Posted July 27, 2009 The ISM824 from Extron might be worth a look. It has the ability to scale various inputs so whilt not listing Seamless switching as a function it may work better than your existing system. As mentioned above the Screen ProII might be woth a look. If you put several SPII's on a controller they become additional destinations. So you set SPII as main screens, SPII 2 as stage screens etc. It's the. Possible to save presets that effect all 'destinations' when you take. There is also the ability to just take on 1 destination or combinations. And Barco have just dropped the price.... Link to comment Share on other sites More sharing options...

Hi Bob,AFAIK nobody makes the product of your dreams. The only way that I know of to achieve what you want, is to have a separate FX scaler switcher for each display. You then take each source and distribute it to each of the scalers. However, some intelligence would be required to operate such a set up, and you would be looking at a cost of £10k plus. The product that I had in mind for you was the Kramer VP-727 http://www.kramerelectronics.co.uk/product...del.asp?pid=434 Link to comment Share on other sites More sharing options...
