can't seen anything on the youtube video. COuld you post a jpg at the good dimensions of your comp, using the camera icon ?
I recommend you show us the video in the context of your page. Since YouTube does its own recoding, it's impossible to tell intentioanl settings apart from potential errors. As Seb said, a JPG of the full movie after keying would also help. Sounds very much like you simply need to tweak keylight#s Despot and Rollback options (again).
I can't show it to you in the context of the webpage sadly as it's for a client website which isn't built yet! However, I have put the file for download here (click the orange button!):
http://www.sendspace.com/file/ya2jog It'sonly a few seconds as an example.
I have put both the despots and rollback up but still no luck sadly. Any suggestions on correcting the noise, and generally making it a better key?
Also, one of these videos totals around 90 seconds, and a 16MB flash file. How can I make it smaller? My current settings are FLV, web small with a Sorenson Spark codec.
Thanks again guys for your time.
I see better what you mean.
First of all, i'll start by doing a tight garbage matte(great tut from aharon rabinowitz on creative cow) , and then i'll key the resulting edges.
If you still have noise due to the spill supression or from the key itself, i'll do a third matte on the body itself, and i'd adjust the edge color with hue/saturation
The noise looks like genuine camera noise from poor lighting with ramped up sensor sensitivity. Therefore, as a start, I'd run the clip through a pre-comp and use the Remove Grain effect or tools like RevisionFX' DE:Noise, Red Giant's Key Correct Pro and so on. If it's DV/ HDV or similar, some de-blocking by ways of similar tools is also recommended. This should already improve matters notably. Then, as Sébastien said, study the super tight junk matte tutorial and apply the technique to your footage. The less pixels to key, the more efficiently the keyer can expand its range on the remaining ones. If you then still experience jaggy/ noisy edges a second application of the aforementioend plug-ins might do the trick. Other options include tools like Twixtor, SmoothKit, RSMB, RE:Fill etc. to mend holes and smear gaps. also, since the person is wearing dar clothes, the old trick of using a dark Inner Glow might also be applicable.
