FFMpeg must have improved since I used it last.

Unless they've changed something since I've used ffmpegX, it seemed a little iffy with the WMV format. I recall it usually losing the audio stream or squinching the video track or something along those lines. The Flip4Mac route is probably best, though for full conversion you have to shell out a little $$, as it is the Microsoft endorsed, approved and maintained means of viewing and manipulating WMV in Mac OS X.

Not too long ago there was VirtualHub by Techspansion, but neither of those are any longer with us. VH did a pretty good job of converting WMV to MPG; there were only a few I ever used it on that it had problems with, and I suspect this was because they were encoded in a version of the wmv codec too new (or too weird) for the ffmpeg, mencoder and other core utils it used behind the GUI to do the job.

NAME

       pfsclamp - Clamp color and luminance channel values to be within the specified range

SYNOPSIS

       pfsclamp [--min <minimum>] [--max <maximum>] [--percentile] [--zero] [--rgb]

DESCRIPTION

       Use  this command to clamp values of luminance and color channels to be within the specified range. I.e. if a value in the channel is above
       the specified maximum or below specified minimum, set the value to either minimum or maximum.

       The command operates directly on XYZ channels.

OPTIONS

       --min <val>

	      Lower bound for clamping. Default value: 0.0001 (10^-4)

       --max <val>

	      Upper bound for clamping. Default value: 100000000 (10^8)

       --percentile, -p

	      Treat given min and max values as a percentile.

       --zero, -z

	      Set values out of clamping range to zero, instead of setting to specified maximum and minimum.

       --rgb

	      Perform clamping in RGB space.

EXAMPLES

       pfsin memorial.hdr | pfsclamp | pfsout memorial_cl.hdr

	      Remove possible out-of-range values, for examples zeros, from memorial image.

       pfsin memorial.hdr | pfsclamp --max 0.95 -p | pfsout memorial_cl.hdr

	      Remove 5% of the brightest pixels from the original image.
