[HELP] Fragments disappear in hand-drawn animation
#9
Problem with presets is:
a. you first need to have decent copy right free source and descriptons of example sources.
b. usually there is no 'one size fits all' filter and you should adjust your filtering per source (or series)
c. whenever Hybrid gets new filters those presets would need to be reevaluated
-> Sorry, but at least I don't have enough time and motivation to do this. (Hybrid is developed by me in my free time.)

Problem is ikely caused by DeSpot and SpotLess (probably mainly DeSpot) which both are not that good to differentiate between details that are surounded by spots to remove and those spots. If you use Avisynth instead of Vapoursynth DeSpot has some additional parameters which might help to lessen the problem for some sources.

You can probably write scripts and use some masking that could help, but there are no generic scripts I'm aware off that could do the job.
All filtering, especially denoising, degrain, dedot, descratch,... filtering will potentially remove wanted details. (basically true for any lossy operation)
-> if you want a surefire preset/filter that can do no hard, you are out of luck.

Some times it's necessary, to apply a single filter mutliple times (potentially with different settings) to properly clean up a source while not causing too much damages to wanted details/data. Also somtimes its necessary to apply different settings on different ranges of the source or change the filter order. Hybrid does allowall this, but it requires that the user has a good understanding of the filters, their order, settings and effects to be used. Which is why by default these options are not shown. (can be enabled under Filtering->Vapoursynth->Misc->UI (or View; not sure about the name) and switchting from FilterOrder to FilterQueue usage.

So any preset that one comes up with might not even work for the whole clip.
Video restoration, enhancement, filtering, etc. usually isn't something that can be done easily or without knowing quite bit about the topics involved.

Ps.: hope I didn't make to many typos (writing on a tablet atm.)
PPs.: when I'm back home I'll try to find some time to look at sample 5 and the new sample.
PPP.: using some of the Degrain filters (SMDegrain, MCTemporalDegrain) with high values might also work well.

Dev versions are in the 'experimental'-folder of my GoogleDrive, which is linked on the download page.
