Dotkill - spatial dotcrawl remover

Myrsloik · 31st December 2015, 17:37

This is a new year's eve bonus from my small collection of unfinished things.

It's a filter doodle that's been sitting around for a long time without making more progress. It's a pure spatial dotcrawl remover that works after field matching or on progressive input. It generally doesn't artifact much and when it does it's rarely worse than the original dotcrawl anyway.

Arguments:

Code:

core.dotkill.DotKill(clip[, napply=1, ignorematch=False])

Usage:

Code:

clip = core.vivtc.VFM(clip, order=1)
clip = core.dotkill.DotKill(clip, napply=1)

clip = core.vivtc.VDecimate(clip)

This filter should be placed AFTER field matching with VFM if field matching is needed. The napply setting is how many times to apply the filter, values between 1 and 4 are generally sane. The higher you go the bigger chance of artifacting. The ignorematch argument is only for testing purposes and should probably never be touched.

It will most likely perform very poorly on purely interlaced content.

The plan is still to add temporal filtering some day but don't expect it anytime soon.

And don't forget to support the projects you like. Especially the ones where you don't have to donate before you can try it.

Examples:

Thank you! Can you share macOS build ?

No, it's currently a prototype filter where I try different ideas and I don't plan on releasing the source until I have added more parts to it.

Download link is down.
BTW- any progress on this ? If not, maybe you can consider releasing the source or and/or macOS build ?

No real progress, I try some ideas now and then but most fail horribly or require more time to prototype than I can spare. I guess I could release the source since there are about 0 other spatial only dotcrawl removers and the idea is relatively simple. Will clean it up in a few days.

Maybe I've seen it but scripts like that are just too much effort to reverse engineer.

There are some interesting tricks you could use for telecined material though (since you know fields are duplicated in a pattern) but it doesn't appear like that script uses it.

I see.

Will the source of DeDot will help ?

Linking random stuff doesn't help. I've looked at most simple ideas already

Sorry if it's look like I am linking to random stuff. I only linked to it because it says that it's a Spatial dot crawl removal.
Good to know you checked and invested much in this. Much appreciated.
