Hi Bob
I don't measure the cams anymore as they dropped this feature for the Bogart version but it worked great for me.)
Tim mentioned that in NTSC it was not working so well so they never used it.
You could have a try if you want.(it is still available for your Renommee)
Make sure all the internal time clocks have nearly the same time and always the same date on them otherwise it doesn't work.
Just before you go on your shoot you connect your camera (by firewire) to your machine open up Quadcam and press measure camera.
Do this one by one and then go to your shoot. When you come back you have to load your footage in the machine in the next 24 hours for the best result.
Then when you go and use the Quadcam software you put your back ground scene up and pick your insert scenes.
If everything works as it always has done for me the cameras should be automaticly in sinc with each other.
When I was using it there was NO problem if I stopped the insert cameras during recordings because it knew when it was stopped you just didn't see any footage in the preview screen. When I started filming again it started showing the picture again so I could switch again.
I realy mis this as it was working for me.
If I was you I would just give it a test run in and arround the house with No breaks in the background camera footage offcors but stopping and starting the insert cameras.
The key is to measure them as close to the event as possible.
Good luck.
