Problem is, it told the computer it supported 1080i/60. Not 59.94 -- 60.00. When connected to the computer, the computer refused to output 59.94. Monitors & the router didn't care -- but the control room switcher & video servers sure did.ough times...)
The microconverters we're using tell the computer they're 1080p/60, but for our application that isn't a problem so long as we remember that this is 3G and not 1.5G, and select the cable accordingly (we don't try to drive 200 feet of 1855a, for example).

Thing is, you're using it for its intended purpose:)

Yeah, that does constitute cheating, doesn't it? :lol:

Just to make it a bit more confusing, you could route it into an Aja FS-1 set to output 1080i/59.94 -- but if the input video was 60.00, that's what you got on the output. (I'm still having trouble believing that part happened, but checked it enough times...)
Yup. Believe it. The AJA FS series (FS1, FS2) won't do frame rate conversion. We had a photog in Rhode Island shoot an entire story in 720/576 SD.
(We had to switch between SD and HD, when going live versus recording. The photog went one notch instead of two). So the frame rate was 25, not the 29.97. It could upconvert but only to a similarly even frame rate. It wouldn't do the proper conversion. They had to ingest the clip into the editing software to actually do the conversion.

The FS2 will frame-rate convert, although there may be limits...I haven't looked. We have one converting two devices (an Apple TV box and a grid cam) from 1080i60 to 1080i59.94. The FS1 certainly can't do that.

We had a smattering of X-Y protocol devices over the years, and some third-party computer software able to change Leitch router stuff using a serial to coax converter. Most went out during the digital conversion, but I still have a GPI interface controlling a Panacea doing EAS switching on one of our dot-somethings.

We have a mess of everything frame-wise. Mostly Evertz and Ensemble Designs, with some Miranda, GVG and Cobalt. The most-used digital glue in our plant is still the FS1's. They're old enough now that I've got to mind the fans, or I'll lose a power supply. Just restocked supplies of both.

There also may be newer in firmware too. The time I had to do this was easily 7-8 years ago.
