The --help for ffmpeg is overwhelming, and the documentation isn't thorough enough. Does anyone know of a good ffmpeg guide? There's a lot I can do with it, I know, but it's not at all newbie-friendly.

It also doesn't help that the option names change often between revisions. I have a few good resources available:
ffmpeg doc
ffmpeg faq
HOWTO: Compile the latest ffmpeg and x264 from source
Encode Video for iPod with ffmpeg
iPod video guide
What are you trying to do with ffmpeg?
Here's a guide to some of the advanced features of ffmpeg:

For those new to Ubuntu most of your answers can be found at help.ubuntu.com or ubuntuguide.org
Well, I've come up with this.
The problem, though, is that somehow the GIF ends up being 7 seconds instead of 14; thus, double the speed.Code:ffmpeg -i benny_lava.avi -s 72x54 -t 14 -r 25 -pix_fmt rgb24 benny_lava.gif
Also, how does the GIF, which is much smaller in frame size than the ~650KB AVI and without audio, end up 1.5MB?

there is a frontend gui for ffmpeg, have a look

I'm not sure why it does this, but this would be a good question to ask on the ffmpeg-user mailing list. There are very knowledgeable users there, but they may ignore your question if you don't follow proper protocol: use the latest svn version of ffmpeg, show your full ffmpeg command (like you did above), show the full response of ffmpeg, don't "top-post", and don't hijack threads. If you need help compiling ffmpeg, this thread should help: HOWTO: Compile the latest ffmpeg and x264 from source.
GIF isn't optimized as a movie codec such as mpeg4. You can compare them to a butterknife and a sword in terms of video encoding compression efficiency.
