Nah, Muvizu can't produce a render of a single character or object. It grabs the whole viewport as a 24-bit image without Alpha channels.

But, if you're forced to do chroma-keying then you'd get the best results using Muvizu's TGA sequence output.


That's what I thought, although graphics cards certainly understand alpha channel, at least with 2D images. The codecs that Xtranormal uses aren't exactly lossless and it maxes out at 720P so I do have issues with pixelation on the edges. It doesn't help matters that there is no camera animation in Xtranormal so I have to often zoom in on these images. This would hopefully be more manageable with Muvizu. Probably the first thing I'd do with Muvizu is try blending Muvizu characters in Xtranormal and vice versa, so this is on my mind.]]> Fri, 07 Jan 2011 17:26:39 GMT http://www.muvizu.com/Forum/topic785-movie-in-background.aspx Message from 83fgh5t1

The edge is very, very subtle, are you sure you're not being a perfectionist about this? If you are using the Keylight plugin for After Effects, I think there are ways to soften the edges. See here:

"Blurring the alpha channel after keying can soften the edges of the matte, which can improve compositing results."

Within Muvizu there's not much you can do, except maybe soften the image using the depth of field options within camera effects.

Let me know if that helps you at all.

1. In Muvizu animate your characters against a pure green sky and ground

2. Make Movie as a TGA sequence

3. Composite the Muvizu sequence with your other movie in a 3rd party editing App.

I'm not sure which codec works best, but xvid has always been alright for me. Just make sure it's not HD.]]> Thu, 09 Dec 2010 06:31:47 GMT http://www.muvizu.com/Forum/topic785-movie-in-background.aspx Message from TheWorkmanAndHesOK
I have an idea for a comedy sketch, but first need to iron out some technical issues.

I have seen some clips where there seems to be a scrolling background or movie in the background.

My idea envolves having an animation done using a different product in the background and a muvizu character in the foreground.

My question is how do I create a background movie with a muvizu character in the foreground?]]> Thu, 09 Dec 2010 02:23:50 GMT
