Removing dot crawl with Avisynth? (1st attempt)
Hello, I would appreciate if I could get help removing dot crawl. I had a faulty TBC-1000 that was causing dot crawl in my recordings and I didn't find out until I no longer had the tapes.
I read the checkmate documentation and this is my novice try: Quote:

Honestly, it looks fine to me. :)
I'd note that my preferred use of Avisynth is to first extract MPEG to Huffyuv in VirtualDub. Then let Avisynth only process AVI. MPEG can muck up the process and make it take longer. |
try this (for an ntsc source:)
Code:
main=last |

This script removes less dot crawl but preserves more detail. I guess that's a compromise that must be made. Here's an example of this masking method applied to another scene: Original2 After2 |
if you want to remove more dot crawl you can use "prewitt" instead:
mt_edge(mode="prewitt",chroma="copy").mt_expand otherwise simply: mergeluma(DeStripe(2,3,16),1) (but it blurs a lot imo) for herringbones patterns (which are some kind of dot crawl): F1Quiver(last, "gn", 336, 10, test=false)# pour enlever les herring bones / dot crawl (traits obliques sur edges), résultat excellent pour ski_sample2.avi !! |

mergeluma(DeStripe(2,3,16),1) did help remove more dot crawl, but as you said, it blurred the image like my first checkmate script. |
