Pictures , QLAB or GrandVj for transition effects..?

Hi, I want to show about 80 pictures at a theatre play lasting one hour.

 

I have never done this before, so I am learning all the time.

I have bought access to the full QLab package.

 

Pictures will be shown on a regular 1024*768 SONY VPL-HW15 projector.

 

The pictures will be used spreadout through the play, and sometimes I want to put the projector to show nothing (go into standby)...

 

Which program will suite my needs best, and how should I use it?

Qlab will run everything video wise fine, but projectors cant just project black (as such). You will always see some form of dark grey output. Available via google is a DMX shutter project, built with a cheap relay and CD drive. or without a relay and a manual push button powered object.

Few things:

 

- QLab can't do transitions other than cross fades on pictures (which it actually treats in the same way as video) without delving into using Quartz patches. For this you need to download Quartz Composer and develop the patches outside the program.

 

- If using QLab you must remember to have a matching stop cue for every video cue you use to display a picture, again this is due to the cue really being for doing video and doing still images as a useful side effect.

 

- You need a physical shutter. There are some Panasonic projectors which have ones which are controllable from a web interface on the projector itself. There are Apple scripts which can be used with the QLab script cue to open and close them directly from QLab. If you haven't got one of these then rigging something up that can respond to MIDI can also be controlled directly from QLab. For a DMX shutter you'll need an intermediate of some kind that can generate DMX by responding to MIDI.

 

I've never used GrandVJ but my impression is that it's more for live video mixing than preprogrammed cuing which is what QLab is for.

 

I hate to say it but the correct solution to this problem might be Apple KeyNote or MS PowerPoint :/
