need rainbow/dot crawl samples

[snowmoon]

Hey everyone,

I'm currently working on a proof of concept for a 3d adaptive comb filter for use on any materal that shows composite chroma problems. I do use and am farmiliar with GuavaComb, but what I'm thinking would be different. We have all seen the rainbows around high contrast edges or sharp color changes. I know it can be done since I've seen processors that can take post-capture-filter-and-encode materal and produce a stable, sharp, and accurate color output. If they can do it then, I should be able to do it before the encode.

I'm currently looking for NTSC torture materal that I can use for testing. Preferably this materal will be 10-30 FRAMES of YUY2 or YUYV materal in huffyuv or mjpeg format. It can be from film, cartoon, cgi, whatever as long as it's had as little processing as possible. Please include as much info as to the source.

You can forward samples to my e-mail eric@snowmoon.com

Thanks in advance
-Eric

I have exactly such a sample in my collection of test clips. It's stored in DV but the artifacting is primarily from the subject which is a moving closeup of a piece of cloth. As the camera pans, the thread pattern creates huge amounts of rainbow. Three samples on their way to you right now.

I found a clip that was posted here some time ago - it shows some "mild" rainbowing - proably good for testing:

Here's some more clips that might be helpfull to you.
The first is some very heavy rainbowing, and the second is some dot crawl. Sorry, both seem to have been through a lot of processing.

I have some Cowboy Bebop samples which exhibit rainbowing. I could use whatever this is. Yes.

I can produce samples if you still need more.

I would like to have some non-anime samples.

Here's a video-source sample. The most objectionable artifacts are the rainbowing in the weather numbers, the dot crawl on the left side of the "NL" box, and the dot crawl on the far right of the screen.

@Wilbert

I've got some samples for you. PM me with an email address and I'll forward. They're the same ones mentioned near the top of this thread.

Ummm... that thread is over FOUR YEARS old.

Maybe I'm not as optimistic as you, but I really, really, REALLY doubt the original poster is still looking for rainbow/dot crawl samples... :D

What's with the Necromancy? Lock thread?
