I normally use PCC. Through this thread I have only just become aware of the Screen Keyer. I have just read the old thread of 2007, but can someone explain, please. What is the difference between using the Screen Keyer and the YUV Curve/Exposure/Gamma tools in PCC? Why would you use one and not the other? What are the relative advantages/disadvantages?

in EDIUS8 and 9, you use PCC and exposure etc

the OP is using EDIUS7 so he does not have PCC

using the screen keyer on a duplicated clip doubles its brightness without increasing noise, so if a clip is shot at 60% of the optimal brightness and you duplicate clip and apply screen keyer, the clip will be slightly too bright, so you would reduce opacity to around 80% until it looks fine in waveform mon

Note that this also works with nested sequences. If you need to brighten the result of a sequence with lots of effects and edits, just create a new sequence, and drop the sequence you want to brighten onto two video tracks in the new sequence, and add the Screen keyer between them.

Conversely, you can create a sequence called "Brightened", add a clip to be brightened to two video tracks, add the keyer, and then use "Brightened" as a source in your main editing sequence.
Thank you!

I got persuaded to do my neighbor's daughter's wedding. Quote "you will be videoing the wedding won't you!"

The reception was in a converted barn, which was lit by candles and Christmas tree lights. (groan).

First thing to do was remove the candelabra from the table in front of the camera, and add some reflective light so as not to ruin the mood.

It was April/spring in the UK and the food did not arrive until 17:30 and the top table had windows behind and it was getting darker as time went on. Pretty much everything conspiring to make it difficult for the videographer.

To use up the time between the church (which I videoed) and the dinner I went round asking which side of the marriage they had come to support and asked for stories from when the bride or groom was younger, that made some amusing content.

So the speeches started and it was slowly getting darker and darker outside. In the edit I ended up with 2 copy layers of video stacked up over the original layer with the screen filter on the top 2, and gradually brought each additional layer into play by bringing up the opacity line to match the scene lighting. Whilst viewing the section it really wasn't noticeable what was going on, the viewer didn't notice the lighting change.

I normally find I have to add a color balance filter to each new layer and just use it to turn the brightness down a little.

Another tip is do all your color correction prior to copying the layer.

Yes it does help not to increase the noise and grain prevalent with the other contrast pushing methods, doing it this screen filter way.
