screen sharing Qlab with SM

[ra byn (robin)]

I was just asked by our SM if I can give him midi control of our Qlab rig
if necessary. In order to do so, I'll locate a JPCooper MCS-2 Midi at the
stage but he will obviously need to see the Qlab screens (two) too.

Questions:

1. Can an Ipad share (2) different Mac screens at the same time?
2. What is considered the best VNC app for an Ipad /Qlab control at the
moment?
3. If I provide a 3rd mac instead of an Ipad & screen share, is this best
done using a hardline for speed?
4. Any other suggestions for letting the SM see Qlab screens in the booth
on stage?

Thanks,

ra byn (robin)

1. i believe only one screen can be displayed at a time with a VNC connection. also, there's some 

differences between VNC and the os x built-in "screen sharing" --- vnc allows the option NOT to control, 

ie to observe only; screen sharing includes controlling the other computer .. this may or may not be desired.  

the mac os x client is apple remote desktop and it can do a lot of great things including multiple screens ... 

there are many other clients available for all desktop platforms -- are you "stuck" with the ipad ? 

2. we have been using LogMeIn for iphone and ipad and desktop clients .. very pleased, fast, etc. 

we tried a few others including iTeleport .. our sound operator uses LogMeIn extensively with ipad to control a win7 

box on our amps & processors network (hi-q bss & crown) -- he loves how fast it runs the remote box. 

3. we have begun installing cat-6 lines around the theatre .. there was a thread a while back about qlab 

being unreliable when wi-fi is enabled, and generally because of a few other concerns we have shifted to 

a private self-contained hardwire network. so far this network is only running ipMIDI traffic, though this 

is going to expand dramatically in the near future with other things like video.

Pretty sure that I've done a screen share with a dual-screen machine before, and BOTH screens are indeed shared to the remote computer.

From talk of a possible third mac, it sounded like Ra Byn wanted to
share one screen from two Macs, not two screens from one. Or am I
misreading?

As Jeremy said, two from one machine is possible. You could do one
screen each from two on a third mac, I don't think you could on an
iPad.

Me, I'd just use a pair of KVM extenders and call it a very reliable day.

i do not believe this is correct... i use mocha VNC on my ipad (not necessarily the best, but among the best free VNC apps available when i was looking) and it connects to multi-screen macs no problem.

while that's true, many (most?) VNC clients can connect in a view-only mode which is effectively the same thing.

yes. overwhelmingly yes.

unless maybe if you had a dedicated 802.11n network with no other computers on it.

cheerio

indeed, the original query regarded the ability to see 2 different macs via VNC at the same time. 

this is only possible with extra trickery -- an app that feeds multiple VNC sessions; multiple VNC apps 

and multi-tasking, etc etc. 

yes it is possible to see ALL of the screens connected to one mac via VNC. this was of course not the original question.

Hi all,

under os x 10.7 this is possible with screen sharing.

I haven't found a app that does it on the Ipad

I have an Ipad now & downloaded Air Display but unfortunately, it seems
that there is no way to mirror the main screen. Instead it's just a second
screen.

Is there an app that is most appropriate for mirroring the main screen
(for Qlab purposes)? I would want to make it where the Ipad cannot affect
operation though.

Thanks,

ra byn

You turn on mirroring in your Displays preferences pane. Then download my QLab Button Bar, which I wrote for working with Air Display!

Rich,

While I have doubt you are 100% correct, I don't see any mirror option
under Display Preferences.

I see "gather windows","detect monitors", "show displays in menu bar"

10.6.8

Where do I grab your Qlab button bar?

Well...

You need to click on Arrangement first - which only appears when you have more than one display connected.

One of the things I'm asked a lot is "how long is act 1, 2, 3, etc..."

Not a huge deal to write down times & add then & factor in post waits &
such but is there a relatively easy way to do the following with a script?

select first cue, SHIFT, select last cue (of whatever part of the show to
be counted) & then end up with an absolute time (not sure where it would
appear).

Since all times are known, seems like a trivial task for a script, yes?

Depends what you mean by a "cue" - if they all follow on, then that's easy. If you have to push GO to trigger them then how can you work out how long between GOs?

This doesn't work if you have looped cues (again, how do you know how long they loop for?), but I've been using it for a while for sequences that can be contained in a single Group Cue:

Of course! So ignoring applause & such, basically just add the running
time of cue X thru Y (whatever is currently blue), ignore any 0 time cues
like notes & such & spit out a total running time.

Along these lines, another tool:

Running time counter (like a pedometer). It's starting point is 0:00.00

If cue 1 is 3:00.00 at the end of that cue,

the counter shows 3:00.00

it would ignore any dead time & simply wait / stop / pause.

If Cue 2 is :50 at the end of Cue 2, the running time would show 3:50

& so on.

You can always reset the counter (new act or just counting a different part).

This would require running something in real time though to learn a total
time.

If you want a quick, "how long is act 1" (ignoring applause) answer, just
select desired cues, trigger script & it says, "25:12.0552" or something
like that.

Just an idea.

You can use MTC for that - along with Timecode Display. You'll have to put the starts and pauses in yourself though - but you'd have to do that with any tool.

If "act 1" is a sequence then you can put it in a Group Cue, run the script I linked to and the Group's Post Wait will be the total duration. If it's not a sequence then there is no total time, is there? Similarly how can you work out how long a random set of non-contiguous cues is? If "act 1" is a bunch of Group Cues, run the script on each, fold them up, select all, copy, paste into Excel, sum the Post Wait column...

This is a really hard thing to write in such a way as to allow for all the possible variations in how people lay out their cuelists. You'll need to write your own tool for how you program, but the ingredients are all there...

Thanks Rich,

Working perfectly now...

So for this production I'll put the Ipad next to the SM (with the touch
function turned off) so he can see where things are at. We tried this last
week with my PC & Ultra VNC & he's already addicted to knowing what is
going on. No more, extremely early standby cues for the fly rail & spot
ops:)

By the way, love the Q button app. Sorry to see you have to start all over
to get it to work with Lion. Not an issue for me yet but what a pain in
the arse to have to play that game. It must be a nightmare for Ios
developers (chasing Apple).
