Crossfade video


I am in need of a script file that will crossfade video clips. By 'crossfade' I mean to blend into the next clip. Not a 'transision' from video to black to video.

To give you an idea of what I want to do. There is a parade that comes through the village. I will go during the week and video a clip of the vacant deserted street. Then Saturday I will video a clip of the parade. I want to blend/morph the parade into the vacant street as if it were coming out of a time warp or was an apperation.

I found one that did exactly what I wanted according to the website demo. When I run it I find that Ubuntu has removed 'pamcomp' and several other programs for 'netpbm' that it requires.

Does anyone know of a script using either 'ffmpeg' or 'mencoder' that does not require 'netpbm'? And will do what I want?

most modern video editors will do what you require.

Thanks for the link. None of those showed up in my google searches. I have Openshop and use it quite often. Its crossfade transition is video to black to video. As are all the others I've looked at. Still have to dig into Cinderalla.

What I'm looking for is a transition that goes from solid through transparent to solid. The parade materalizes on the vacant street as if it only appears every hundred yeas. The transition takes about 4 minutes or how ever long it takes a parade to march fifty yards.

you can do that with layers. overlap the layer of the two videos do a fade out and a fade in over the two and end the fade out before it goes to black. as you will be overlapping the exact same background, from what i understand, it will not be an issue.

again just about every video editor ive played with, not many mind you only about 4 or so from final cut to adobe premier, to cinderalla and a few others. if they dont have the built in tool, you can just use layers to get that exact effect.
