Detarestore will not help with that scratch, it's basically a wrapper around Spotless to make it less destructive. (restore some moving parts)
Haven't seen anyone do a port for Vapoursynth or make it a proper script, even for Avisynth, so I wouldn't hold my breath for it to appear in Hybrid any time soon.
Got just the last frame in the native resolution? (normal Inpainting should work fine on this, but applying it on high resolution content is a pain, since you easily run out of memory.)
