Comment:

 Replying to [comment:3 JoeJohnson]:
 > I am not getting an error when I create the video in either case.  When
 I open the video created without "-vf fps=25" in VLC, it does not play
 properly.

 Please use {{{-vf fps=3}}} (or a higher value) if you need vlc playback.

 > I am able to play the video with a codec pack like k-lite, but not with
 VLC.

 > The CPU being a 100% makes the computer unusable during encoding.  I am
 looking for a way to shorten this time, or drop the max CPU use to around
 80%.

 Sorry, I don't think there is anything about the problems you see that can
 be fixed within FFmpeg.
 On a Posix system, you can use {{{nice}}}, I believe there are ways to
 reduce the priority for Windows tasks.
