I've been reading the forums for a while, and have learned alot! I bought myself an A470 to play with and thought I'd post the first driving time lapse I made:

I was having a really hard time with all the video processing stuff, so I figured I'd post a little bit of with I did, maybe someone can post suggestions or improvements.
Here is how I made the video:
Setup:
Used the
Ultra Intervalometer script to take photos with a 2 second delay.
Set to focus at infinity (I had to add '
set_prop 6 3' to the intervalometer script, because the the camera would not stay at infinity for some reason, even in manual mode)
Set to a resolution of 2048x1536
The camera was mounted (upside down, with a suction-cup mount) to windshield (which is why it moves a few times), plugged into a 120 power supply which was plugged into a power inverter.
I ended up with 1524 photos.
Post:
I already have
imagemagick and the
mencoder(part of mplayer) installed
I pre-processed each photo:
mogrify -path processed -extract 2048x1152+0+0 img*.jpg
cd processed
mogrify -rotate 180 img*.jpg
mogrify -resize 1920x1080 img.jpg
The first command crops and creates a new file in the "processed" folder. In this case I cropped the 'bottom' of the photo away (which was mostly sky because the camera was upside down)
the second command rotates them 180, and
the third command resizes to 1920x1080 (1080p resolution)
Then I turned them into a 1080p mpeg4:
mencoder -nosound "mf://*.jpg" -mf w=1920:h=1080:type=jpg:fps=24 -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:keyint=132:v4mv:vqmin=3:lumi_mask=0.07:dark_mask=0.2:mpeg_quant:scplx_mask=0.1:tcplx_mask=0.1:naq:vbitrate=10125000 -o time_lapse.aviI don't know quite what the mencoder command does, because it's a frankensteined command from a bunch of different websites.
