It's easy enough to make the background of a still image transparent, by adding it in an image editor and saving it as a PNG . But how do you do this for a video? I appreciate details will vary by NLE (mine is Magix Movie Edit Pro 2013 Premium) but I'm sure the principle must be common?
Take the simplest possible example, namely a white object on a black background. Such as this clip downloaded from
http://www.motionbackgroundsforfree.com/technology-free-backgrounds/free-technology-ba...-passing-time/
I wanted a simple clock to occasionally drop into my holiday DVDS. Although this one is OK, I'm not completely satisfied and have been trying to make my own. But I don't see how to make one that I can then just import into any project without the extra step of specifying the transparency. In MEP it's via Video Effects > Chroma Key, and then choosing Black in this example.
But all these downloadable videos do it with no such extra step. It appears to have its transparent background already embedded and recognised immediately by the video editor. How are they made please?
