Next to Fonts Chroma Keys are my favorite torture. Oh well I'm trying to clean up some chroma keys using BCC 8. I'm getting decent results with chroma key with multifilter adding matte cleanup to choke it a little bit. Now the edges are okay but the shirt buttons and light blue, yea light blue, shirt are reflecting some of the green and slightly keying out. If I was on a GVG switcher I'd use the forced key function and make a garbage oval wipe forcing the foreground through. I tried multi filter make alpha thinking I'd be able to draw a shape on top of the existing alpha and fill the problem key area with solid white. I can't seem to find the right combo to get this working. Is this even possible in BCC 8 using multifilters?

I had responded earlier to a slightly differently worded version of John's message that he sent directly to me, and I'll paste my response below. BCC9 adds a BCC Chromakey Studio effect which has this capability integrated in a single effect but I offered some suggestions for trying to deal with these kind of things in BCC8 as well...

With BCC8 I guess you'd have to stack 2 effects. Here's a screencap with voiceover I just did with some ideas ;

But this was added as an integrated part of the effect in BCC9 - see if you watch for a minute or so here ;

There's both inside and outside shape there...
