Not too sure of the correct name for this. All it does is blend all frames from a source over a certain amount of time - like a long exposure photograph basically.

Potential uses: - Making a long-exposure photo - Noise reduction in photography (part of what I made this for originally) - Timelapse photography (what I use it for now - it makes much better timelapse, no jerkiness) - Video effects, with a shorter frame length

No, this one is pretty cool with light painting. The other one is crap in comparison ;) Press space to clear.

It's because the colourspace in the RII is messing up the colour values.

Cool. I like how you're combining it with the colours too!

The colours were a result of the framecombiner patch as well . . . in the end I put everthing on top of each other with the movie of two people dancing as a mask on top.

Very slick!! Congrats. I've worked on a video comp with a similar effect. But didn't get it to work in QC. Thus I made it in static way using photoshops video capabilities. Have a look at the outcome over here: http://www.atelierschork.com/work/a-thousand-kisses/

What I actually wanted to achieve is a "combined image" with 100 continues frames of a movie to be used. But ongoing in the sense of "always adding a new frame to the stack and taking the oldest away".

Any idea how I could achieve this with QC?
