Avisynth dot crawl effect (make your video ugly on purpose)

raffriff42 · 4th April 2014, 01:57

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)

Download dotcrawlplus.avsi
Dropbox dotcrawlplus folder

Due to overwhelming lack of demand, I have issued version 2 - now with rainbows! (Are unicorns next?)

It uses a more subtle dot crawl generator too.
You can once again make unrealistically huge dots if you want them.

More preview images and script download (too long to post) here (dropbox.com)

If there's one thing I've always missed in my Blurays and Netflix, it's analog artifacts. This would be perfect for pranks. Thanks!

That's actually kinda neat

Not sure the rainbow artefacts look quite genuine (usually the cross-color would be sharper?)
