WMV is making me upset
I'm okay with not understanding things. Happens all the time.
What I'm not okay with is not understanding things that I should understand. When I don't understand something I should understand, it frustrates me. When I get frustrated, I get upset. I get upset, I get angry.
I wouldn't like me when I'm angry.
This is what I don't understand: I have a video file, WMV. From a webinar broadcast, so nothing complicated, just audio (mono) over static Powerpoint slides. 1024x738, 48 minutes. 2.78 fps, data rate 271 kbits/sec. File size: 39 megabytes.
However, the second I touch it -- nay, look at it -- in this case, to trim a few minutes off the front and back -- and save it, the file size increases, even as the display size decreases. 640x480, 45 minutes. 2.55 fps, data rate 1704bits/sec. File size: 53.2 megabytes.
Right now, I'm using Quicktime 7 Pro to edit, with Flip4Mac Studio Pro to export to WMV (Quicktime X doesn't allow exporting); Studio Pro doesn't let you customize the default settings, though I've had the same problem using Windows Movie Maker.
I'm not adept at video, so please tell me: What am I doing wrong?

As you notice, your data rate increased.. more bits per second means a higher file size as there's more data to transmit.
Look for settings to tweak the data rate in f4m

Friend of mine posted the answer on my Facebook: Use a lossless WMV editor like Machete (PC-only) and avoid recompressing and futzing with the original file, so you end up with a shorter file, of the same resolution, at a slightly smaller file size.
