This is done all the time. Check out my Mars website,
http://home.woh.rr.com/frostdesign/ . Not only did I create new video from
stacked frames, I used different formats from AVI, for smaller file sizes. I
ended up with Windows Media Files (.wmf), because dialup accounts took
forever to download the AVIs. These WMFs are located in the individual month
links along with the best images of the nights shoot. I took the home page
one step further, and created animated gifs, which could be manipulated even
further in a nice dropdown list, but at a small loss of color depth (gifs
use only 256 colors). I'm amazed at how well these images hold up to the
original AVIs, as really not much detail was lost through the extra
compression.

With programs like registax, k3ccd, or astroregister (?), is it possible
to shoot a
few minutes of sky at say 10 frames of second in avi format, and then
stack
sequentially 5 or 10 frames intoa new image, then stack the next 5 or 10
frames into
a second image, etc. so the resulting stacked images are in a avi file?
For example,
if my avi has file has 100 images, can I automatically sum each
successive group of 5 into a new image to produce a new file with 20
images?

The end result of this process should be a shorter movie with individual
images
created from successive sections of the original.

This reminds me to ask the following question. I'm creating a sky image at
4 avi
frames per second, and, when I playback the avi file, it plays back in MS
Media
Player as slowly as it was created. Is there a way to speed the playback
up to 15 or
30 frames a second?
