Green Screen in Adobe Premiere Pro 2.0 at DVinfo.net

Antwuan Gabriel · September 6th, 2007, 01:41 PM

I'm having a slight issue in Premiere Pro 2.0 with green screen. I've shot my footage with a perfectly lit green screen however when i import into premiere and put the green screen key on the footage, I don't get a clean key. The background is taken out but the footage that was filmed looks a little transparent itself. The background that was imported looks a little hazy(not as clear as it should). Is there a proper way to key in PP 2.0? I've done keying before in 1.0 and 1.5 without a problem. Please help!!!

There are settings for that effect ("Threshold" & "Cutoff") that control how the mask is applied.
Have you adjusted them? By default they are as far apart as they can be, T at 100 and C at 0. You want to move them to be as close together as possible, while maintaining a good mask. First lower the T until the green-screen is all blacked out (it helps to check the 'mask only' box, then only the transparency values are displayed), then raise the C until the greys on your foreground object go white. Mix & serve chilled...

Hi there

I've used both Premiere 2.0 and After Effects Keylight plug in to get Green screen and its day and night, especially using higher res acquisition...

Premiere gives you a really basic Green screen facility... it can work ok but I find you usually always get a hallo effect, even in HDV..

Keylight is just brilliant... you have loads of fine tuning.. and it gives fabulous Keys..

I find my best keys are to shoot in HDV... import HDV and edit my clips in Premiere 2.0.. then save out as uncompressed HD avi. This I import into After Effects before applying the Keylight filter... This gives very nice results... I then use AE to downsize to SD and out put as an SD avi file... this can be cut with my regular Dv footage..

Cheers

Gareth
