Peter,
Why are you using the DVI Extender? The Gefen should be converting the DVI to SDI so I’m confused why there is a DVI Extender in the path.

Peter,
The Gefen scalers have worked pretty well considering what we paid for them. Every once in a while the dual channel scaler will go black, I’m not sure if that’s a scaler issue or the TripleHead2Go. Most of the time doing a power cycle on the Gefen fixes it, but one time it would not come back and it took a few days for it to “reset” and work again. We bought 2 of the dual channel scalers on eBay for $450 so we used the second one as a backup. 99% of the time they work great, though.
Our setup is DVI out to TH2Go, DVI out of all 3 TH2Go outputs into the Gefen scalers, then HD-SDI straight into our ATEM switcher. I believe your configuration will work just fine.

Peter,
The ATEM switchers only work in one resolution and frame rate at the same time (one reason why the prices can be so low). That means every source (camera, computer, vtr, etc.) has to match that resolution and frame rate. A 1080i camera will not work on an ATEM setup for 720p. You’ll have to either convert the cameras or find ones that match your format.

Hey Peter,
We are also using the Hyperdeck and Premiere. I had to setup a preset to accept the files, but haven’t had any issues after that. We are 720p59.94.
I’ve attached some screen shots of our preset in case you need it:

Brian,
Yes, we ended up finding a solution that came close to our budget. Had I known what we needed during the budget process, I would have allowed more for the DVI to SDI conversion.
I initially budgeted $350 per output to convert the DVI TripleHead2Go to HD-SDI, assuming the Blackmagic DVI to HD-SDI converter would work. The problem is the TripleHead2Go does not use a standard broadcast refresh rate. We needed 59.94 for the ATEM to see it at 720p. Therefore, you need a DVI to SDI scaler that reclocks the signal, too.
I found 2 used Gefen DVI to HD-SDI Pro Scalers on eBay for $450 total. I used one for 2 channels of the TripleHead. I also found 1 Gefen DVI to HD-SDI Plus Scaler on eBay for under $700. I used that for the 3rd channel of the TripleHead and use the 2nd Pro Scaler as a backup.
Overall, they’ve worked great. It holds a solid picture and the ATEM never seems to have an issue with it. That said, you still have to baby them in some ways. When we lose power (very rarely), the converters will forget settings or just refuse to work for a little while. It’s only gone down on us once in the last 8 months. Hence the backup.
If you have room in the budget, I highly recommend checking out the Matrox DVI converters instead of Gefen. I’ve heard better things about them. Hope this helps, have fun!

I second this issue. Dropped frames and audio sync issues in Flash Media Live Encoder, Softron MovieRecorder and Telestream Wirecast.
On a brand new Quad-Core Mac Pro we get dropped frames on ProRes capture and Activity Monitor shows only 8% CPU usage.
Latest BM drivers, too.
