mtn.exe: argument for option -b is invalid at '.80'
movie thumbnailer (mtn) 200808a copyright (c) 2007-2008 tuit, et al.
mtn saves thumbnails of specified movie files or directories to jpeg files.
for directories, it will recursively search inside for movie files.
usage:
mtn.exe [options] file_or_dir1 [file_or_dir2] ... [file_or_dirn]
options: (and default values)
-a aspect_ratio : override input file's display aspect ratio
-b 0,80 : skip if % blank is higher; 0:skip all 1:skip really blank >1:off
-B 0,0 : omit this seconds from the beginning
-c 3 : # of column
-C -1 : cut movie and thumbnails not more than the specified seconds; <=0:off
-D 6 : edge detection; 0:off >0:on; higher detects more; try -D4 -D6 or -D8
-E 0,0 : omit this seconds at the end
-f tahomabd.ttf : font file; use absolute path if not in usual places
-F RRGGBB:size[:font:RRGGBB:RRGGBB:size] : font format [time is optional]
info_color:info_size[:time_font:time_color:time_shadow:time_size]
-g 0 : gap between each shot
-h 150 : minimum height of each shot; will reduce # of column to fit
-i : info text off
-I : save individual shots too
-j 90 : jpeg quality
-k RRGGBB : background color (in hex)
-L info_location[:time_location] : location of text
1=lower left, 2=lower right, 3=upper right, 4=upper left
-n : run at normal priority
-N info_suffix : save info text to a file with suffix
-o _s.jpg : output suffix
-O directory : save output files in the specified directory
-p : pause before exiting; default on in win32
-P : dont pause before exiting; override -p
-r 0 : # of rows; >0:override -s
-s 120 : time step between each shot
-t : time stamp off
-T text : add text above output image
-v : verbose mode (debug)
-w 1024 : width of output image; 0:column * movie width
-W : dont overwrite existing files, i.e. update mode
-z : always use seek mode
-Z : always use non-seek mode -- slower but more accurate timing
examples:
to save thumbnails to file infile_s.jpg with default options:
mtn.exe infile.avi
to change time step to 65 seconds & change total width to 900:
mtn.exe -s 65 -w 900 infile.avi
to step evenly to get 3 columns x 10 rows:
mtn.exe -c 3 -r 10 infile.avi
to save output files to writeable directory:
mtn.exe -O writeable /read/only/dir/infile.avi
to get 2 columns in original movie size:
mtn.exe -c 2 -w 0 infile.avi
to skip uninteresting shots, try:
mtn.exe -D 6 infile.avi
in windows, you can run mtn.exe from command prompt or drag files/dirs from
windows explorer and drop them on mtn.exe. you can change the default options
by creating a shortcut to mtn.exe and add options there (right click the
shortcut -> Properties -> Target); then drop files/dirs on the shortcut
instead.
