You gave your first one an ".mpg" extension, it should be ".mov" other than
that they both work fine in QT5 here.
Just to clarify, an MPG or MPEG is a type of file completely different than
QT or MOV; you created a quicktime file which uses a Motion JPEG codec,
which is similar in concept to MPEG, but a completely different type of
file.

Thanks!
Your motion macros remind me of those made by Chris Colefax. Do you know if
there are any major differences?

A while ago, I did download his macro, but I needed it to do a couple of other
things for an animation I was working on, so I just started from the ground up
and wrote a new macro that would do a pretty similar thing, just in a
different way. I always hate using other people's macros when you don't
really understand exactly what is going on. Now after downloading his macro
again, I read the copyright notice in the documentation and feel kinda bad.
Is there a way I can have my post removed from the scene-files group to comply
with his copyright?

That's great! You always learn a lot that way.

You shouldn't! You can't copyright a technique or a concept. You can only
copyright so-called "intellectual property". It means that you may not copy
Chris Colefax's files or parts of them without his permission, but if you've
created your own macros from scratch, then they're your own completely and
you have the copyright.
BTW, you have copyright of your intellectual property no matter if you write
a copyright notice or not. The notice just makes it clear for others.

No need to. :)

Thanks. I feel much better now. In addition, I noticed that the hips were
swaying the wrong way, so I just switched the sway to a negative value and
added in a checkered floor (shudder) for reference. Hope this looks more
realistic.

Sure does! :)
I just wish I could get my QuickTime player to loop... :(

Looking back at the old posts, I noticed Al, the walk/running alien. I
saw your comment about IK not being very forgiving to extended legs and
I know exactly what you're talking about. In the file I posted, I
altered the knee macro so that it would point the limb in the direction
of the ankle if the points are too far apart. I also added in a feature
so you can set a certain amount of resistance so the knees don't snap
when they fully extend. In my code, I set it so the limb would show the
resistance between the fully extended joint +/- the added distance of
the cushion variable.

I just wish that I didn't have to uninstall my quicktime in a rage when
it usurped all my animation format associations without asking and then
wouldn't play them anyway. "MPG: Unable to recognize format"... then why did
it steal the association?

In my system if one of the hip points are too far away from the ankle I move
the hips closer.

Resistance sounds like a good idea. I'll have to look into that.
What I'm thinking about doing is simply to move the hip closer to the ankle
so the distance is, say 95% of the length of the leg. (The actual percentage
would be a variable controlled by the user.) Is that what you're doing too
or is your method more sophisticated? I didn't quite understand your
explanation.
BTW, I'm working on my own IK system in these days, so I might post
something in a few days. :)

Actually, I spliced three graphs together so the output length follows the red
line simply using #if( ) statements (yes, I know a switch staement would be
much easier). The graph shows the length between the hip and ankle points on
the x-axis and the adjusted length of the limb on the y-axis.
The equation for the parabola is just:
y = maximum length - 1/4 * 1 / cushion * ( x - cushion - maximum
length ) ^ 2
This allowed me to set a specific zone where the limb would resist full
extension. It works pretty well based on my experiments. In one example I
tried, I just bounced the hip point straight up and down and the legs followed
the jump without snapping at all.
