How to apply/not apply filters according to frame number in Hybrid?

[andrewschen]

Seems like there's no built in feature in Hybrid to do so.

There is.
It's just one of the controls normally hidden, to avoid overloading the ui.

Enabling "Filtering->Vapoursynth->Misc->UI->'Apply only to'-controls" adds:
   
to all filters (where this makes sense), which allow to apply filters only to specific frame sections.
In the dev version, there is also "Filtering->Avisynth->Misc->UI", which offers similar for Avisynth.

I can't understand the tooltip description of it, could you please explain it to me?

For example, a 1000 frame video, frame number 1-1000, if I want to skip filtering in 101-200, What should I put into the 'Range' field? And what is 'Offsets' for?

a 1000 frame video, frame number 1-1000,

1000 frame clip has frames 0-999

if I want to skip filtering in 101-200, What should I put into the 'Range' field

so you do not want to filter 100-199.
Range works the other way around it specified where to apply the filter, so range should be "[0-99] [200 999]".

And what is 'Offsets' for?

Cycle sets the size of the frame grouping, to cycle 5 would chunk the video into packages of 5 frames.
Offsets then specifies which frames to keep.
So with cycle 5 and:
offsets=0 1 2 3 - the first 4 frames of every 5 frames would be filtered
offsets=2 - the third frame of every 5 frames would be filtered
offests=2 4 - only the third and fifth frame get filtered
