[HELP] Vapoursynth, Frame, Stabilize not working

[Selur]

Shaking usually is characterized as short jitters to the sides/up/down, the movement in your clip is probably to slow to be counted as such a jitter.
Hybrid atm. only supports range values for 'Stab' of a maximum of 10 frames, looking at the clip that is way to small for your clip.

Even using something like range 100 and min/max 120:

# stabilizing using Stab
clip = lostfunc.Stab(clp=clip,range=100,mirror=0,dxmax=120,dymax=120)
# cropping the video to 480x456
clip = core.std.CropRel(clip=clip, left=120, right=120, top=12, bottom=12)

doesn't work, propably since the clip doesn't have much details that could be used as reference points.
-> I agree that 'Stab' the stabilize filter which Hybrid used can't handle your video.
Sadly I also don't know of any filter for Avisynth or Vapoursynth which could 'deshake' your content.
