Nun bin ich endlich fündig geworden:

http://public.hronopik.de/vid.stab/features.php?lang=en


Für den Fall, dass die Seite mal verschwinden sollte:


default case: 

transcode -J stabilize -i MOVIE -y null,null -o dummy
transcode -J transform -i MOVIE OUTPUTOPTIONS -o STABILE
      
 The first line creates a file MOVIE.trf with the detected relative 
transformations between subsequent frames. The second line uses this file to 
convert your movie into a stabilised one. The maximal translation is limited 
to 48 pixels and the time smoothing is 10 frames. 
 Extended transformation size and more smoothing: 

transcode -J stabilize=maxshift=100 -i MOVIE -y null,null -o dummy
transcode -J transform=smoothing=20 -i MOVIE OUTPUTOPTIONS -o STABILE   

you can also use 
tcmodinfo -i stabilize
tcmodinfo -i transform




Stabilize plugin
[filter_stabilize.so] v0.61 (2009-10-25) extracts relative transformations of
    subsequent frames (used for stabilization together with the
    transform filter in a second pass)
[filter_stabilize.so] Overview:
    Generates a file with relative transform information
     (translation, rotation) about subsequent frames. See also transform.
Options
    'result'      path to the file used to write the transforms
                  (def:inputfile.stab)
    'maxshift'    maximal number of pixels to search for a translation
                  (def:height/12, preferably a multiple of stepsize)
    'stepsize'    stepsize of search process,
                  region around minimum is scanned with 1 pixel
                  resolution (def:2)
    'allowmax'    0: maximal shift is not applied (prob. error)
                  1: maximal shift is allowed (def:1)
    'algo'        0: brute force (translation only);
                  1: small measurement fields(def)
    'fieldnum'    number of measurement fields (def: 20)
    'fieldsize'   size of measurement field (def: height/15)
    'mincontrast' below this contrast a field is discarded (def: 0.15)
    'show'        0: do nothing (def); 1: show fields and transforms

Transform plugin
[filter_transform.so] v0.61 (2009-10-25) transforms each frame according to 
transformations
 given in an input file (e.g. translation, rotate) see also filter stabilize
Overview
    Reads a file with transform information for each frame
     and applies them. See also stabilize.
Options
    'input'     path to the file used to read the transforms
                (def: inputfile.stab)
    'smoothing' number of frames*2 + 1 used for lowpass filtering
                used for stabilizing (def: 10)
    'maxshift'  maximal number of pixels to translate image
                (def: -1 no limit)
    'maxangle'  maximal angle in rad to rotate image (def: -1 no limit)
    'crop'      0: keep border (def), 1: black backgr
    'invert'    1: invert transforms(def: 0)
    'relative'  consider transforms as 0: absolute, 1: relative (def)
    'zoom'      percentage to zoom >0: zoom in, <0 zoom out (def: 0)
    'optzoom'   0: nothing, 1: determine optimal zoom (def)
                i.e. no (or only little) border should be visible.
                Note that the value given at 'zoom' is added to the
                here calculated one
    'sharpen'   amount of sharpening: 0: no sharpening (def: 0.8)
                uses filter unsharp with 5x5 matrix
