Video quality is poor even with best settings

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run glapse.
2. Set Screenshots "Quality" slider to 100 (max).
3. Set Video "Quality" slider to 23000 bps (Best).
4. Take some screenshots (at least to fill some seconds of video, say 50@5FPS = 
10 seconds)
5. Press the "Make video" button and wait for it to finish its job.
6. Watch the resulting low-quality video with your video player of choice.

What is the expected output? What do you see instead?
A high quality video. A mpeg-1@23kbits/s horror.

What version of the product are you using? On what operating system?
glapse 0.2 on GNU/linux ubuntu 11.04 on a Samsung N140 netbook (not upgraded, 
1Gb RAM) and GNU/linux ubuntu 9.04 on a intel Core2Duo 6400-based desktop PC 
with 3 Gb of RAM.

Please provide any additional information below.
It's because of the default settings of ffmpeg, I think. Test videos encoded 
with glapse (timelapse.mp4) and ffmpeg+libx264 (h264-2M.mp4) attached.

Possible solutions:
Please consider using other video codecs like mpeg-4 or h264. Higher bitrates 
(say, 1000k) and  variable bitrates also help, but file size scales very badly.

I've changed the command to generate the video. I now use -codec copy to copy 
all images as they are (no quality adjustments). I've remove the quality 
sliders from the GUI since it doesn't make sense anymore. Now you control video 
quality from screenshot quality.

Video files are a bit big, I'm working on another solution.
