scripting a older source

[ExSphere]

I just recently ripped the Tenchi dvd's and the source seems to be rather funky. I get a lot of black spots and junk that randomly pop up in the footage. Like in the middle left shot of this.

And im also getting some rainbow colors on the outline of my characters like in this shot.

If you know any scripts that can fix this let me know. It might just be the dvd's suck.

I have no idea what the problem on the first one could be but, The second one sounds like Rainbowing( believe it's called?) try using DeRainbow or DeHalo

The black dots are just part of the source it looks like (springing from the methods used back when it was created). I don't think you can do anything about it with avisynth. You might be able to mask it out in your editing program

The second one is indeed rainbowing. In addition to what Enigma suggested, I'll throw in Tcomb()
You'll have to read the documentation to find out how to come to the right parameter values.

We call those 'cigarette burns'...erm...yeah, that's a problem with the transfer from film. Aside from masking it out in the editor, I'm not aware of any solution for that.


And yes, that is rainbowing. I'd use DFMDeRainbow and LUTDeRainbow in tandem; that combo eradicated virtually - if not all - of the rainbows on AnimeEigo's original Oh My Goddess! OVA discs with just the defaults, but those discs are kind of the textbook model for horrendous rainbowing. Just be aware that A) they should be placed before any IVTC operations*, and 2) they will royally slow down the script, far more than each one individually would.

*It is best if the derainbowing comes before IVTC, but if I remember correctly, due to the way the filters act, it is pretty safe to use DFMDeRainbow afterword. So you could essentially run two passes - LUT+IVTC first, and then a second with DFM. Obviously works better if you're using HuffYUV clips instead of scripts in the editing program.

Thanks for the help!

Assuming they only show up for one frame and then disappear (I'm pretty sure most of the dirt on the original NGE DVDs was like that), that's the kind of thing that temporal and spatio-temporal smoothers are supposed to be able to help with. I believe DeSpot is supposed to be specifically for that type of film noise, but I've not used it very much, so I never wrote it up.
