wmv goes from 4 Mgs to 79Mgs???????????

[Guest]

Hello. I have a recording off of Live Meeting. Its a 4 megabyte .wmv. I
need to delete the first 1 min 10 secs from the front. I went into MM and
did that. But when I try to save the movie to my computer, it says it will
take over 5 hours and will be a 79 megabyte file!!!!!!!!!!!

What exactly is wrong? The movie is about 29 minutes with the deletion.
Help!!!!!!!!

You are trying to use a higher bitrate than used the original video and
possibly increasing the video resolution when you re-encode the file.
Explorer should show you what the bitrate and video resolution of the
original file are. You could also use the GSpot utility (download from
gspot.headbands.com ) to identify what bitrate and resolution of the file
are. Pick the same or as close to it as you can in WMM when you save your
clipped copy. From your description of the file, the original video must be
very low bitrate, low resolution, or a combination of both to squeeze 29
minutes into a 4MB file. At approx 980kbps bitrate I can only compress 79
seconds of 320x240 resolution video into a 5.6MB file. At 168kbps the same
79 seconds of 320x240 video compresses down to a 1.5MB file

The time estimate is based on the processing power of your computer vs what
you set WMM to do. It will take how long it takes, but by not increasing the
resolution or bitrate from the original it should reduce the estimated time.

That makes perffect sense! Thanks!
