Over Scan question

[Jonathan Porter]

Can someone please explain what the over scan function does in the project settings tab, I notice it is default set at 3%. How or why would I change this? Does it change the amount of viewable image information on finished projects.

It largely affects the way in which transitions are rendered, and I believe it also affects the overlay display of the overscan guidelines (if switched on).

Worth a Wiki on "overscan" to get the full picture. Your images will be unchanged with the settings.

Some transitions act differently depending on overscan settings. (Watch out with computer playback with settings other than 0%!)

Mine is set to 0% always.

Actually thats what I was mainly interested in, computer play back etc.

Make sure to see what they look like on the TV once you have it set to 0.

I am runnng everything through the NX card out to a LCD TV and the overscan does not seem to be effected. Is this were I would expect to see a difference?

PS Have just bought the Class on Demands, Complete Training for Edius 4.5 DVD through a GV retailer here in OZ, well done mate.

Overscan may not show up on consumer LCD and is switchable on pro models.

Check the difference between your NX output and what appears on your PC overlay.

Just for fun... change the overscan setting to something crazy, like 50%.
Now choose something like the Circle transition.
It's actually kind of cool!
As I recall (in days of yore) handling of transitions in this manner relieved much of the Rex/Storm video handling, thus more RT. 3% was a lot in P3 days!
I cringe when I see an old project on a PC or projector!
