" -m, --model=(transl|transl_and_scale|affine)\n"
" Set motion model. The default is affine.\n"
" --outlier-ratio=<float_number>\n"
" Outliers ratio in motion estimation. The default is 0.5.\n"
" --min-inlier-ratio=<float_number>\n"
" Minimum inlier ratio to decide if estimated motion is OK. The default is 0.1,\n"
" but you may want to increase it.\n"
" -r, --radius=<int_number>\n"
" Set smoothing radius. The default is 15.\n"
" --stdev=<float_number>\n"
" Set smoothing weights standard deviation. The default is sqrt(radius).\n"
" --deblur=(yes|no)\n"
" Do deblurring.\n"
" --deblur-sens=<float_number>\n"
" Set deblurring sensitivity (from 0 to +inf). The default is 0.1.\n"
" -t, --trim-ratio=<float_number>\n"
" Set trimming ratio (from 0 to 0.5). The default is 0.\n"
" --est-trim=(yes|no)\n"
" Estimate trim ratio automatically. The default is yes (that leads to two passes,\n"
" you can turn it off if you want to use one pass only).\n"
" --incl-constr=(yes|no)\n"
" Ensure the inclusion constraint is always satisfied. The default is no.\n"
" --border-mode=(replicate|const)\n"
" Set border extrapolation mode. The default is replicate.\n"
" --mosaic=(yes|no)\n"
" Do consistent mosaicing. The default is no.\n"
" --mosaic-stdev=<float_number>\n"
" Consistent mosaicing stdev threshold. The default is 10.\n"
" --motion-inpaint=(yes|no)\n"
" Do motion inpainting (requires GPU support). The default is no.\n"
" --color-inpaint=(yes|no)\n"
" Do color inpainting. The defailt is no.\n"
" -o, --output=<file_path>\n"
" Set output file path explicitely. The default is stabilized.avi.\n"
" --fps=<int_number>\n"
" Set output video FPS explicitely. By default the source FPS is used.\n"
" -h, --help\n"
