The AV-3170, while bigger and beefier, has given me problems. Specifically, it doesn't scale the image up large enough to fill the screen. I haven't found a way around this yet, but it's on my list. The other 2 have worked fine and output S-Video for decent quality. You can order directly from the links above, or get a better price from B&H.

Finaly we use 2 computer with Isadora, each one mixing DV video (the delay is not very important) and 2 movies, The two are synchronised by ethernet. We buyed XGA amplifier and Firewire repetitors (computers are 50m from stage), all is piloted by a bcf2000, work perfectly with quality.

They are very fuzzy, and the image is pretty washed out no matter what. Also they have the black border, the computer video is always inside the title safe area only. The zoom feature is only to 320x240. I also have a Canopus TwinPact which is an Analog to firewire converter. It works VGA->composite or VGA->firewire. as well as composite -> firewire. It is a Very crisp image, I can't recall what the zoom features are. I've really only used it as composite to firewire. It's quite expensive though $500. I am also very interested in a scan converter that: A) is cheap-ish B) will display in the full composite video area not just safe frame. C) can zoom to a 640x480 area of a 1280x1024 area or a 800x600 area of a 1600x1200 screen D) optimally it will remember the zoom and pan settings after Power down. E) has a fairly good image quality. -- Hal Eagar - Media Effects Artist http://haleagar.com Director - Digital Performance Institute http://digitalperformance.org DPI-office 646 442 4435 | Hal-cell 917 257 8440

The cheaper thing I've found working well is the Kramer VP-501xl, http://www.kramerelectronics.com/indexes/item.asp?name=VP-501xl I've tested it and I'm using it on a show at this time, the image quality is good, no latency, lots of fonctions in the converter to zoom, move,... with memory The price is ~350$

That does sound good; Kramer seems to makes solid stuff. The page and PDF don't mention zoom and pan, but you say it's included. Do recall off hand what sort and level of control it gives. Specifically if you did buy 4 can you 2x zoom each one to a quadrant. or hey get crazy and try and put 9 on a 1600x1200 at 533x400 for a "cheap" video wall controller. 9x350 = $3150 so not dirt cheap, but not to bad. -- Hal Eagar - Media Effects Artist http://haleagar.com Director - Digital Performance Institute http://digitalperformance.org DPI-office 646 442 4435 | Hal-cell 917 257 8440

hal User Apr 28, 2008, 4:38 PM Post #7 of 7 (1214 views) Shortcut Re: [hal] vga to video converter [In reply to] Can't Post I've recently used the Kworld PCTV scan converter. The quality is quite good, but it does not recall settings when powered down. The default is to underscan but you can get this to fill the full image with no black border, but it is a multi step process of expanding the H and V and shifting the H and V. The zoom says it is a 2x zoom, but it does not work that way. I believe that at all resolutions up to 1280x1024 it will zoom to 320x240 pixels high. and at 1280 it zooms to 524x240. you can position the zoom with a panning feature. overall better than the T-View converters, but still not good enough. -- Hal Eagar - Media Effects Artist http://haleagar.com Director - Digital Performance Institute http://digitalperformance.org DPI-office 646 442 4435 | Hal-cell 917 257 8440
