Inspired by recently reading the
Avisynth gone wrong thread here, and spurred on by a question on another forum (
Betacam/betacam Sp Effect For Virtualdub?), I give you
dotcrawlplus, an Avisynth dot crawl effect. For convenience, it can blur the chroma and add noise at the same time. There's a wrapper function with a few named presets, or you can set all the options directly.
It's not terribly elegant. I'm sure the effect could be refined. It's intended for use as a quick special effect for a music video or whatnot; it's
not a very good composite video emulator. You are not going to fool an expert with it. (I suggest a hardware solution for a perfect emulation)
