Sync cursor greyed out with color gradient

Randy Brown wrote on 7/11/2004, 7:58 AM
I just shot my first green screen the other day and now I'm having a heck of a time in post. Although I took a lot of care at the (location) shoot not to let any light on the subject spill onto the green screen and vice versa, my lower background track (landscape stills etc) are looking pretty hoaky (especially with the artifacts around the edges on some clips; I guess I need to buy an adjustable spot to use as a rim light on the subject). I've decided the only way to salvage this is to put some color gradients behind the subjects with soft colors that match the subjects' clothing. I thought some movement of the color would be nice too so I started to keyframe them when I noticed I couldn't sync the cursor to the timeline...it's greyed out. Any thoughts?
TIA,
Randy
EDIT: BTW, I just discovered on one of my clips that they make a womans jacket that is almost exactly greenscreen green!
I gotta hire an assistant.

Randy,
First, generated media is 'generated' and therefore has no 'time' associated with it until it's rendered...
To shift the color background, use the Secondary Color Corrector, sampling first the color to be shifted or saturated, and then adjust with the SCC. Works pretty darn good.

Hmmm...seems like you've said this before in another thread...I'll try to pay better attention : )

Thanks Spot,
Randy

Randy, if you can't get the background separated, mail me a still. I'll see if I can help out.

In my opinion unless you are weatherman stay away from greenscreens,bluescreens whatever. They just plain look like, well ,like they were shot over a greenscreen.
That was a lot ohf help ,sorry randy.
hope you get it acceptable..

I was hoping technology had changed enough that it wouldn't look so cheesy. I've seen some stuff that looked great but I guess you gotta know just how to light it (and great equipment probably helps)

>>hope you get it acceptable.. <<

We had to do the whole shoot at an office and it was the client's idea (a local United Way) to greenscreen with the intention of inserting landscape stills in post. Anyway I warned her it was my first greenscreen shoot but she insisted so....some actually don't suck....but some do : (

We had an edit a while back where the client supplied all the footage, bluescren stuff lit terribly .After lots of fussing and moaning what finally worked decent was using stills as the background .

Greenscreening in DV is a challenge at best, but Vegas and Storm, plus Commotion Pro all do EXCELLENT jobs of working with DV media. It's even harder for PAL folks, but Vegas still pulls a good key from the media.
Needless to say, preproduction and production are critical to achieving a good screen, but if you take steps to do it right, you'll find it remarkable.
John Jackman has some good info on how to do it right, I've got a few tutorials myself, Stephen Schleicher has some great tutorials, and so does Ken Stone, even though they are Apple-related.
Randy, send it to the info address, and it will be forwarded to me. Send a png, not a jpg.

Hey Spot why dont you share your greenscreen method that you showed some of us at the VASST classes. the one with ,I believe it was your Grandmother ?or a member of your family. Done with no lights, a perfect key!
Or is that little secret for just us VASST attendees? (if so , too bad for the rest of you, a valuable nugget for sure)

That was my mom...It's no secret, it's in my book...I just didn't want to type a novel and I can't copy/paste info from the book. (publishers rules)
In honesty, I'm keeping most of that kind of info over on the DVinfo.net and DMN forums.
It did look wicked good, didn't it?!
