Recorder switcher activity

Hi, does anyone know of a way to record a switcher's activity during a show? I'm not talking about the video output, but a file that describes what the switcher *did* on the day. Mainly I'm just thinking about crosspoints (inputs) switches and maybe simple mixes and keys and somekind of time reference like time of day.

Or does a modern switcher (sorry my practical experience stops at a GVG3000) output a signal describing what it's doing. Something more than just a tally.

Any ideas, no matter how outlandish, greatly appreciated.

Will

The kalypso does have an internal logging feature used for troubleshooting. If I'm not mistaken this logs every single keystroke and panel surface action by time-of-day. It shouldn't be too long of a stretch to be able to export this data into an XML style sheet, but the engineers at GVG would need to figure this one out. To get the data you go into the "Status & Diags" menu and select "Grab SW Diag Data" and select a folder into which the "SW Diag Data" folder created by the process will be dropped. Good Luck! And if you figure out a way to use the data, please let the rest of us know.

Special points for Bob who hit the nail on the head. That's exactly what I'm trying to do. But my idea is to get the activity out to XML rather than an edl. But simple input changes could be easily conveyed by an edl. I looked into the tally option. The new GVG switchers support a serial tally interface which details every input on every M/E and bus. What I can't remember is if tally's are instant and therefore frame accurate. There always seemed to be a delay as I recall ( I was a TD in Denver about 8 years ago.) Someone mentioned getting access to the LAN running switcher hardware. While it seems nearly impossible to get access to a switcher's internal protocol, wouldn't this information show up on a PC in the network? As I understand it, the Kalypso can be controlled via a PC. So could a GVG 300 - I remember an EIC who could change any input at will from the back of the truck. So thanks for all your suggestions. Will

[quote="Bob Ennis"]If I read Will's posting correctly, I believe that what he may be trying to accomplish is something that we in the live-to-tape area have been wanting for a while. By capturing the button presses & transitions, you can end up with what amounts to an EDL. The editiors of the show could just import that EDL and, using ISOs, quickly find, extend, shorten, or otherwise edit shots just by jumping to the appropriate event. With the move away from linear devices - where you can shuttle to visually find your edit point - to non-linear devices, where you can easily skip over material, having an already-built EDL that was created at the time of taping could be quite helpful. This is something that some of us approached GV with a few years ago, but nothing really came of it. As I said, I know that SONY did this a few years back as an interface between their editors & switchers, but I don't know if the current generation of switchers will support this.[/quote] Sony is supposed to be able to do this with the Plug-In-Editor they sell with the MVS series. I don't think the software is quite there yet, though. But the concept is that any button press becomes an EDL line so you can easily go back later and edit. RE

First thing that comes to mind for me, if you just want to see what the TD is doing, hang a camcorder from the ceiling and point it at the switcher. Now the high-tech way, most of these switchers nowadays connect panel to frame via ethernet, you could probably set up another computer on the LAN that will record all of the data that goes between the two. The tricky part would be getting it into human-readable form, though. I have no idea if it would be possible to "play back" the data back out into the LAN and the panel would just step through the show...? It would be an interesting experiment, at least.

Well if you want outlandish: You could record one big giant macro and replay your whole show in 4 seconds. Cheers, Mike

My understanding is that SONY used to be able to do this on the 7000 series - I don't know if the current product line can do it. I know that other than picking off the tally information, GV switchers can't do this.
