Here's a screen shot of the most egregiously offending portion.
It's not in any of the stills, so, I'm guessing it's an artefact from dta?
Should I try another bmp - to - AVI converter?

Yes try another one. I use TMPGEnc if you change to using PNG
(recomended) there is a plugin that you need to get. But that is easily
done.

That is good, not counting the artefacts. But how did you get hold of
DTA? It must be antediluvian. ;-)
I remember using it last century, no in the last millennium. :-P

It took a while to write, then fix, then go around and around in total n00b math
circles, etc.
I was very happy to get the belts to work nicely using cones to mimic a v-belt,
to have one gray cone to give the eye something to follow and perhaps enhance
the sense of motion, and to get the belt to sag somewhat and not look so
perfectly CG.
In the event I have time, I might try to add some psudo-random shaking and
wiggling to the belt, and maybe the frame.
Though maybe I ought to work on learning layered textures and synching up the
normal with the texture. Considering using isowood.
I followed Friederich Lohmueller's animation tutorial. DTA is what he
recommended on his site, it seemed trivial (it was! Yay! :) ) and I figured it
was good for a first animation to use what obviously worked, and then perhaps
proceed from there.
Is there a reason to use png vs bmp for animation?
I tried the other program - seems to get rid of most of that artefact dross.
Do you think it's just a function of DTA, or the AVI encoding format?
TMPGEnc is outputting it to m1v format, so I have no reference.
Thanks so much for the help.

3 more questions:
How to make this an animated gif?
I have a request to make this 10 seconds long - no idea how to do that except
copy and rename each frame bmp 10 times.
Is there a way to make this loop by default? Some sort of internal metadata tag
that would automagically set the default viewing option to loop?
(I'd settle for someone knowledgeable enough in html to show how to just get it
to loop on a webpage...
Thanks again for everyone's help! I'm learning a lot. :)

Gif format has instructions for time before next frame and also number
of repeat/loop.
gif as movie usually use also delta-encoding from one frame to the next
to achieve better compression (first frame is expensive, next ones are
only describing the changing pixels areas)
Have a search in any search engine about "gif editor", it should provide
you with some tools.
Remember that the gif is limited to 256 colour-palette. I wonder if MNG
format did find its way in the W3C and browsers' implementation.

A good idea. But you can split your animation into parts. For instance
this short clip
http://www.youtube.com/watch?v=urX5kI-5e4E
is repeated several times in this animation.
http://www.youtube.com/watch?v=j3ez6FIgdNs
Well the short code loops in the longer animation code. because of the
symmetry you don't need to have a full life cycle of the belt completing
a full revolution.

That is a good idea to do early on or you end up like me, never getting
round to doing it. :-(

An excellent site.

I cannot fault your logic.

File size. No matter how big your HDD, it will fill up as you make
version after version, getting things right.

TMPGEnc will also output to mpg, which is the favoured format here. Or
so I was told. It does default to m1v, though. Select stream type -
system. Then go into settings. I am no expert and others may give better
advice. I use Automatic VBR and change the max and min bit rate from
high settings to the lowest that will give good results. (This is where
a lower file size comes in useful as I make lots of tests.)

That's pretty much the way I have it. Though I had to _move_ the odd-colored
cone around a full revolution in order to get that sense of motion. That took
some figuring. The Belt moves around several times, but the counterweights on
the cranksshaft have to make a full 360-degree revolution.
> It would be good but no shortcuts I think.
I can probably just add a modifier to the belt motion to have it bounce up and
down a little during the movement.

Computers do have a [delete] function. ;D
Or you could just burn them off to DVD.
Does the bmp vs png source affect the final video size, or it its own
independent format?

I did not think of that. A split thing should do the same for mine. I
keep going back to it. It is not complicated enough, for me.

That is the fun bit for me.

Yes something has to the full cycle.

I would like to see that.

Whoa! You're talking heresy there. I've lost more through system crashes
than I've ever backed up. ;-)

I've got a 3 Tb external drive now but old habits die hard.

I don't know for sure, I would think so. I stopped using bmp after
someone, who will remain nameless, made a snarky comment about the noob
who was posting uncompressed files. They were a mean lot here, in the
old days. ;-)
