I generally decide how long I want the animation to last then work out the
number of frames needed. Discover the size is too big then see what I can
get away with. 25 fps is good but sometimes you can get away with 15 fps. A
I'm afraid.

why is every second frame identical to its previous frame?
nice animation though :)

Is it? How are you seeing this Zeger? Heh, I've just watched it spin
about 50-60 times and I can't see what you mean. I spotted that there is
still a glitch between the last and the first frames though, (as Stephen
pointed out with my previous anim), but I think this is because I had it set
at 8 fps which produced a file at about 700-800kb's, and OE wouldn't let me
post it because the end file size was over 100,000 bytes(?!) - so I upped
the frame rate to 12 fps and dropped the file size. This then posted at the
size you see, but produced that glitch where it wasn't there at 8fps, it was
'really' smooth. What should I have done as regards the size of file before
posting? Should I have compressed the images first, and 'then' use TMPGenc
at 8fps?
> nice animation though :)
Thank you Zeger. You wouldn't believe how much I enjoyed playing with
animation. I think I'm hooked. :o)
I know I have a lot to learn...

Yes, I often use the anology of; "If I hit a bum note on my guitar, I will
know it, and the tune will be ruined. If it sounds great, then I'm on the
right tracks."

I've heard this before with one of the commissions that I'm making. I
think this is my colour blindness kicking in... I'm using Pink as the base
colour for the metal (which is correct for rose gold), but then adjust it so
that it looks like the metal that I work with, (to me).
Maybe I should saturate the colours a little?

Well, I actually watched it frame by frame using media player classic after
seeing in the properties that it truly was 24fps (it didn't look like it :))

that's the problem: your frame rate is set to 12fps, but that's accomplished by
doubling each frame. You should actually render twice the amount of frames for
a slower animation, and *always* use 24 or 25 fps, for a smooth animation

it's fun animating stuff, isn't it :)
can't wait untill I have a Core 2 Quad computer and POV-Ray 3.7, cause things
are getting really slow now :-/

haven't we all :)

Ah, that's great. Thanks for the advice Zeger, that will put me right.
Another quick couple of questions if I may? So what kind/type of animation
would it be whereby you actually use a framerate of 7.5, 8 or 12? (I.e.,
lower than the size you recommend). And what about the other way around?
Faster than 25fps?

Yes it is. The nice thing is seeing what you've built, and I think if you
accomplish this and it's what you expected, then imagination kicks in for
other animation ventures. That's the cool part, I think. :o)

Especially for me, as I am now sourly tempted to go for the IRTC Anims
round with the present subject... :)
Yes, I dream too...

lower framerate is never needed, unless you either want to reduce your filesize
or want to imitate cheap anime's :p
faster framerate actually *does* help improve your animation to appear more
'fluent', but a rather fast computer is needed to play them, so use motion-blur
instead.

Wikipedia has a bit of information on frame rates, as well as (ironically)
persistence of vision, which helps explain what minimum frame rates might be
acceptable for your desired outcome:
http://en.wikipedia.org/wiki/Frame_rate
http://en.wikipedia.org/wiki/Persistence_of_vision
I've always taken the approach (as Zeger implied) of choosing my frame rate
first, and then working out the number of frames to render. There are
standards, too, depending on your target medium. For example, .avi standard
is 15fps, NTCS film is 23.98fps, etc. etc.
My 'rule of thumb' has typically been not to go below 15fps, and usually
there's no reason to go above 24-30fps ...although there's an interesting
comment here on VirtualDub's website about the reasoning behind using
120fps:

Thanks Zeger and How. That's great advice, both.
You know, I spent about two hours early this morning looking at past IRTC
animations, (because I can now), and to be honest, I was gobsmacked by what
was there.
One of my favourites is in the 'Unnecessarily Complicated Devices' round
of 2002, entitled: 'Brass and Steel' by Daniel Dresser:
http://www.irtc.org/anims/2002-04-15.html
If I did that, I would be proud of myself. I have other favourites too.
:o)
