I added an event listener to the class. So I started rendering frame 1. When frame 1 is completed, I call the save function. The ImageSaver class saves the images and dispatches an Event. When this Event.COMPLETE is being dispatched, I just render another frame. After rendering I call the save function again and wait till the Event.COMPLETE is being dispatched again. etcetera. ;) Well, I think I've got my own mini-render engine. It works perfect for creating sequences of images (or just videos which use a lot of CPU or cannot be displayed at real-time). While rendering I counted the frames and stopped saving after 1000 frames.So, now we can render more heavy effects and create videos, right? :) In this video 1000 images are rendered by actionscript, using additive blending and a BlurFilter. The movements are based on a Perlin noise. Not very heavy, but when running it in the FlashPlayer, I've cannot reach more than 11fps. The full version is 800x600 with transparency, 30fps.Yes, this video is created with actionscript]]> I’ve created a new video, and this one isn’t rendered like I said in the previous post (using flash > export movie > .mov), but I used the ImageSaver class every frame.

Single image:

Video output:
Yes, this video is created with actionscript

I used Premiere to merge all those images into a video.

I draw lines using Perlin noise as input. Check this out:

I was also experimenting/figuring out how to convert a actionscript generated movie to video. I never knew it was possible (or that easy) with the Flash CS3 (maybe because I never tried). Just choose file > export movie > and choose .mov extension. The video isn’t smooth, because (when I save it) it is not really rendering, it’s just like an invisible screencapture, I guess. So I can’t use more heavy CPU things. Thats a pity.

But maybe I could use my ImageSaver Class to create a movie-sequence by saving frame by frame as PNG.
