I used this script to deinterlace/bob some footage I had

mpeg2source("C:\users\user\dvd rip\berserk\toshio nakatani interview.d2v")
Tempgaussmc_beta1mod()
Selecteven()

and in the resulting footage I noticed some strange dots located on the person's shirt (outlined in attachment). What are these and how can I remove them?

Dot_crawl

I don't think so, because then it would be everywhere. I think it's just artifacts of TGMC having problems with certain spatial frequencies.

I agree, what I meant is that being an artifact visually similar, a filter that corrects dot_crawl probably also correct that.

Could be that the underlying EEDI2 already has problems with that pattern. Try with (EdiMode="bicubic") and see if it reduces those artifacts. If it gets better indeed, then EEDI2 is to blame.

In addition, try with blocksize=16. It could be that MVTools with the standard blocksize 8 is finding false motion on that pattern. 16 should be more stable.

I could try that. However I instead fixed the dot crawl by using:

TDeint()
TemporalDegrain()

No dot crawl and very HQ denoising/degraining.

There may be some blocking on edges though, as there are some clips from the anime that the interviewed individual is talking about. This issue brings me to THIS (http://forum.doom9.org/showpost.php?p=1443116&postcount=17) thread again which is STILL, as of yet, unanswered.

It's not dot crawl.

And regarding the other post you linked, I'm not surprised people go away when you make statements like this:

no one who replied in this thread is giving or plans to give any helpful and truthful advice

Just saying... :)

Don't be coy. No one offered any help from the start. The only reason why I posted that is because you people like to play these little games and waste time.

I'm sure people are making sincere efforts to help you. But not all problems have solutions or are easily solved.

Sorry you are having a bad experience here, and good luck with your issues.
