Chromakey confusion when adding masks and layout.

I'm sure I've done this before - but can't work out how!
I have shot chromakey footage where mics etc are in shot which I can easily mask out with the mask tool and turning down the outside section I want to loose to 0%. However, how do I then apply the chromakey and only key out the greenscreen as it then shows the masked section as black bars.
To complicate things I then want to use the layout tool to position the layer into the right place and scale it.
The only way I can make this work is try and use the block colour on the mask tool, and also in the layout tool and find the right shade - but I'm sure there is a simple way of telling edius to ignore the masked areas.

You can do a search but in layout pit the background color to the same color as your chromakey color.

I have explained this a few times in detail so a search will get you there. :(

Thanks Steve. Yes - thats the only way Ive ended up doing it - but its a shame that once you mask something and put it at 0%, or crop something, that it doesnt then simply become invisible so that the layer beneath is revealed (a bit like on photoshop)

Its mainly that the chromakey is one of the few effects that still needs updating - hence the blue tick on the effect meaning it is not 10 bit and does not support alpha channels.

If you use a third party keyer the mask would work properly. Ignite Pro has a pretty good keyer that works with the mask although I have found that it causes crashes occassionally.

That makes sense David. So does that mean as soon as I apply the Edius Chromakey it degrades the footage down from 10bit to 8bit?
Does a 3rd party keyer appear as a key affect - or a a video filter? I’m hoping the latter so that you can reorder it (eg put it before or after colour correction etc)

I use Robuskey and it is a filter and I usually drag it above the layouter, then I can zoom and position all day long with the layouter

Thanks Anton. I’ll have a look. Is it 10 bit and ha does 4K nicely?

yes to all, but you need a good graphics card for realtime 4k playback with Robuskey

I have not noticed a degrade in quality using either the chromakey filter or the chrominance filter (which has the same limitation) so I don't know if it just means they only use 8 bit colours to do the job but won't degrade other 10 bit filters or I have simply not noticed them doing so.

Robuskey is probably the best third party keyer. Any third party ones turn up as filters and can be re-ordered. Oher options would be Ignite as I mentioned and I think NewBlue does one. There are trial versions of all of these.

We do! It's called Chroma Key Pro and you can find out more information (as well as download a trial version) on this page:
