You can do similar averaging (like Warp's) with Paint Shop Pro v5 but on any
type of image.

there is a little known motion blur patch for 3.0x by Ron Parker. I can
e-mail you a copy if interested.

But only two images at once...
To average, for example, 13 images with PSP would be a challenge
if each is to be weighted equally.
I believe ImageMagick (UNIX), via the combine statement, can
do weighted averages. This excellent package is really a must
for folks doing image manipulation in UNIX.

Yeah, render a short animation showing the moving parts of your scene
moving as they would over a very short period of time. How much each object
moves is dependant on how fast you want them to appear to be moving. Then,
when you've rendered the animation average all the frames together into a
single file. There are many utilities and image manipulation apps about
that'll do the averaging, DTA (Daves Targa Animator) springs to mind, I
don't have a URL for it, but I _think_ it's on ftp.povray.org.

Is DTA already capable of handling more than a few thousands of kilobytes
of data?

I don't know, I've only ever used it for relatively small animations.

Go to my homepage listed below and download the short utility "Warp's
Targa Averager" from my downloads page. It will produce a single
averaged image from a multitude of initial targa images. There is no
PSP required or anything else.
My site has the Win95 console version of the utility, and there is a
link to Warp's original site that has a DOS version. Original source
code is included to port the utility to Linux or whatever one needs.
An additional note: the utility can also create "delta images", which
are the result of subtracting one image from another. This can be used
on a series of animation frames in an attempt to reduce their storage
requirements for lossless archiving, etc. The "delta frames" will need
to be unconverted before being viewed normaly, but Warp's utility can
also perform this restoration. This is a somewhat experimental
feature, in that delta frames are not a standard storage format. Warp
was nice enough to add that feature at my request, so I could perform
some tests of delta frame effectiveness. With some animations, it does
help reduce lossless storage requirements considerably when combined
with lossless compression techniques.

Hey Glen,
What do you recommend as a maximum object translation
from scene to scene. I tried a ten frame image last night
that failed miserably. I owe it primarily to too much spacing
between the moving objects in the scene and wondered if you
had a good feel for a recommended amount.

This question was not an answer to my post, but being the author of the
averager program maybe I could express my opinion?-)
Common sense says to me that the object which I want to be motion blurred
shouldn't move more than 1 pixel from frame to frame. As far as I have tested,
this gives very good results. Even better results can be achieved by moving
the object less than 1 pixel each frame.
The total amount of movement is up to what do you want to. More movement
looks like the object is moving faster (more frames, more blurring), and less
movement looks like it's moving slower (less blurring).
For the image http://iki.fi/warp/pics/Takeoff.jpg I calculated 40 frames
(man, it was slow with my 486 66MHz!).

For high quality still images, I agree with Warp totally. If you are
creating an animation with a fairly high framerate, I think you might
get by with coarser steps in movement. It's sort of cheating, but the
typical viewer might not notice during an animation.
If I'm not mistaken, that high-end rendering program that was used in
Toy Story, typically uses relatively coarse motion blur for
animations. I once read a usenet post from one of the engineers that
admitted it wouldn't work so well for still images. :)
