Green Screen Problem – BCC Chroma Key
I normally do all my keying in AE, but I have a series of quick shots that we did that I need to key in Final Cut. The key isn’t the problem. I was able to pull a very nice key using the BCC Chroma Key plug-in. I have my shot looking exactly the way I want it, but as soon as I render, it all goes to crap!!!
I don’t know if this is a render settings issue or what, but my colors are all shot, and my blacks become a magenta that is now semi-transparent.
Does anyone have any idea what is happening here???

Here is an example of what is happening. (keep in mind this isn’t color graded or anything…I’m just trying to illustrate the problem I’m having after rendering.)

Maybe you need to check in the filter’s tab as to what kind of output are you looking at.
I use primatte RT and it works very well for me.

Let me try this one more time…
I had to compress to jpeg, so it looks pretty crappy, but the key on my timeline looks how I want it until I render.

I’m really not sure because everything looks great until it is rendered. I can even scrub through the footage and it looks good. But when I render…it turns to crap.

I’m already working with ProRes422. I’m really confused here. If I bring it into AE, I can key no problem…but due to the work flow and other people involved in the project, I really need to pull the key in Final Cut.

I may just have to end up working in AE or Motion. No idea…

The magenta is your spill-suppression/edge control in the keyer; you may have it turned up too high? Try choking it back a little?

I don’t think that’s the problem because I have the spill suppression set just how I want it. Take a look at the photos in my earlier post. Before I render, everything is looks the way I want it to.

I’m having same sort of problem. Only bit more drastic…
I have a ProRes clip and two keyed tracks over it (both of them ProRes clips just like the first one). Everything looks fine on the timeline but after rendering, the two overlay tracks with chroma key disappear completely!I’m completely lost here…

As I have already stated, I am already working with ProRes footage in a ProRes sequence.
