Hi, I'm trying to make a movie with a combination of a video and a few photos, but got a problem while saving the fileas WMV, it stays on 0% and the remaining time goes longer and longer. Anyone know this software well can help me would be much appreciated!

Do you need to save it as wmv?

Rendering is a long process
There is no way to make it faster.
The higher the quality and resolution of the contents and output settings, the longer the render will be.

Try rendering a small portion of it to see how long it takes so you can estimate how long for the whole movie.
Try various quality settings as well.

Keep in mind that effects also make renders longer.

And how big are each of the files that you are using?
