I watched the video on the home page where the animated character walks up to talk to camera talking about Musvizu, he walks behind the desks in the back ground and people are walking behind him. How was that done as that is something i am interested in doing real world video with an animated character. I been looking via forum but so far found nothing. Is there some special editor used to get him to align to the images i.e. desk so he is not walking through them.

there are a couple of ways to do it. And you're right, to my knowledge there isn't a tutorial on the topic. If somebody knows of one, I'm sure they'll post a link.

1) perhaps the easiest way to do it is by using layers in your video editing software. Layers work like stacks of pictures... the layers on top appear to be in front of the layers below. so, if you want your character to walk behind a desk:
  • first you'll need a desk with a transparent background. Most photo editing software will let you remove the background in images and make it transparent. I won't explain how to do that because all software is different... but that's your first task: creating the foreground object (desk) with transparent background (so you can see whatever is behind it)
  • with the video of your character walking loaded into your video editor, import the desk and put it on the layer ABOVE your character. Now when your character walks, he/she will appear to be behind the desk
2) The other way still requires you to make the photo with transparent background... but in this case you might put it on a backdrop in the Muvizu environment, and position the backdrop so the desk is wherever you want it. When the character walks behind the backdrop, it will look like he/she is walking behind the desk.



so the real trick here is creating the foreground object with transparent background. Its easy to create photos with transparency... but that only works if your camera stays fairly stationary. If you want VIDEO with transparency, then you'll need to look into more complicated solutions that I'm not prepared to talk about here.

Here's a link to a video showing how layers work in HitFilm Express, a free video editor that many of us have enthusiastically embraced for the many solutions it provides to Muvizu directors like us.

First i want to thank you for such a fast response. Let me understand this! if i want real life props I would use layers, so if I want a video as my background i would put that on a different layer? I am not going to be using static images they will be videos with animated characters interacting with the viewer. i.e. talking. The foreground layer would be the animated character with chrome key? And this would give me something like whats on the home page of Muvizu correct?

I hope i got the understanding now.

1) The real-life video would typically be your background.... (bottom layer)
2) your muvizu characters would appear in front of the background (middle layer)
3) then, in order to make your characters look like they are INSIDE the background, static images (like the desk I mentioned already) can be inserted into a top layer, so the character in the middle layer can walk between the foreground and the background


here's another video worth watching:

Hi,

Since muvizu introduced layers, you don't need chroma key anymore. If you render the video as a png sequence and put your characters on a separate layer than the background, you get a transparent image sequence which you can import as a movie in a video editor and overlay it on another video track.

cool thanks to both of you. The Character on diff layer worked in hitfilm express. I have adobe Premiere and after affects as well and will give them a shot.

Adobe Premiere and after effects both have layers, so if you're already proficient in those, they'll work too.
