Nice effort restoring the motion blur and hair, but the hard edges are noticeably soft.

I totally agree. Although forum image compression doesn't help ;)

Regarding Rami's effort. To my eye the shirt that is not in motion has very clean edges as well as Alex's right cheek. The hair is a bit soft, but then again hair is.... soft. Not that I should presume to know anything about Alex's hair softness.

Forgive the double posting, but it seems that the original post did not include the attachment. Perhaps I will have better luck with this one!

Here is a bog standard Edius Key ie. no fine tuning:

Thanks. The jpg I saved fom FCPX does look even better, but as you already said, the compression to a mere 32 KB doesn't do much good. The one I exported was 290 KB

Here's a quick dirt key I did with FCPX internal Keyer on Matt Davis' green screen footage. I pulled the footage off his vimeo video. It was a Prores 422(proxy). Just wanted to see what I could do with it.

vimeo.com/97876659



Here's the settings. Normally, I would denoise the footage first but I felt it would be like cheating. But with denoising it looks even better. Anyways, thanks tpayton for the shout out.

PJA - Great looking key. Can you post a screen shot of your inspector settings?

Hey guys I'm seeing lots of shadows on the corners of your results, especially the upper-left corner that should be keyed out and perfectly clean.

EDIT: Using the cruddy MP4 that this guy uploaded to Google Docs I was able to get satisfactory results with both but Premiere was faster. Ultra key is pretty easy. The problem with the FCPX keyer is that it assumes which color you want to key out. It takes a lot of work to, say, key out his shirt INSTEAD of the green if I wanted. Sometimes I have to drop the keyer on a clip and remove it multiple times before it keys out the color I need it to.





I also decided not to cheat with a white background which could hide outlines. And actually I think I'm starting to like the FCPX key better. It's sharper.

Yeah, I noticed that a bit too late. Of course it could be easily removed with a garbage matte, preferably prior to handing it off ;-)

Recently I saw Mark Spencer's excellent 3 part tutorial on Advanced Keying Controls in FCPX.
Very clarifying on how to tweak and fine tune a difficult key.

They were published in this article on FCP.CO (the 2nd, 3rd and 4th videos on the page)

www.fcp.co/final-cut-pro/tutorials/1423-...ree-tutorial-roundup

I am doing a lot of green screen interviews at the moment. I am using a Lastolite collapsible green screen and two Arri 800W open face spots with a green gel in front to evenly light the background.
Two 300W fresnel spots as backlight with ND .6 to prevent the use of a dimmer
A 100W Dedo light as a hard key/sidelight from the interviewee's right side (almost 90 degrees)
A 1000 W Chimera Softbox as a soft key, placed just a little left of the interviewer.
Two Lastolite reflectors that blocked any green spill from the Arri lights and the one on camera right was placed in such a way that the light of the dedo on the left bounced to just lighten up the dark side of the interviewee's face.
I used an EX1 and an Atomos Samurai to record 10 bit ProRes 422.


Here a some stills of the results








And from the setup

Just a quick tip…
In full screen you can advance through the video posted using the arrow keys to really see the differences between the different keyers. Too fast otherwise.
Be nice to know how he used each keyer. Was it auto-key only?

Thanks rj for the interview set-up shots/info. Not sure about the chrome legs on chair though.

Hope this helps, Greg

Hehe, it were all medium shots or closer, so no chrome tubing in the shot.

Not so. Just drag the strength slider all the way to zero and you in fact renounce the color FCP X had chosen to key out. Then you can choose the colors you want.

By the way, if you go to that link, click the file menu to download the 124MB source file.

This more direct link worked for me (even after I'd signed out of my Google account)

docs.google.com/uc?id=0B7Oll8R1pIjyUFhrV...aQWs&export=download


By the way, my mum will be happy to see you all working with this footage.
