Well, what do you expect with such a texture? You do know that most, if not
all, video-codecs subdivide the image into cubes of something like 2x2, 4x4,
8x8 etc.

Depending on the codec, these blocks then get various compression based upon
the color-changes, frequency etc, additionally based upon the change from
frame to frame. With such high frequency noise, you won't get anywhere
decent without an incredible bitrate and insane non-compression. That's at
least how far I've come with Freeware codecs. Divx, Xvid etc might have some
options available for cases as these, but I rarely see such detailed
textures in shorts or movies that I'm not sure even they can do something
about it. It's far more common that the detailed background is *motionless*,
thus requiring just a few frames to build up properly and then stay that
way.

Note that this comment is entirely subjective and based upon my knowledge of
a few different codecs. There might be a codec suited for exactly what
you're after, and uses the proper way to encode it, but generally,
high-noise (as in frequent color-changes from pixel to pixel) is hard to
compress, even for still images, so it's worse in an animation.

That sounds a bit hash, for you Tim.
In the snipit RusHHouR posted, it is the text object that is moving and the

I do agree that the texture is not suitable for an animation and he should
use a less noisy one.

Sorry if it sounded harsh, wasn't the intention. I just saw his MPEG with
the moving background and the moving text. The question was quite honest,
I'm not sure what he'd expect with such a noisy texture. Perhaps the phrase
"you do know..." sounded a bit arrogant. Sorry for that. It's a common
german phrase (at least with the people I know) which, when spoken softly,
implies more a "NOW (because I'm telling you) you know that...". I mean no
harm. :-)

Ach! I know you would not want to sound harsh (did you notice my Freudian



The phrase "you do know..." sounds much nicer than "NOW (because I'm telling
you) you know that...".
I did not see his animation as my work site would not allow me to download
it. I rendered the 500 frame snipit and it looks worse that my stationary
cube in p.b.a.

Nope I didnt know how the codecs worked... actually.. =)

But... basicly, if I want to have the whole background moving like that, it
should at least be textured at a higher scale, right? Or else it will
flicker. Should be worth a try at least...

Will also try Antialias_Depth=3 and Sampling_method = 2, never used those
before..

Speed Warning:-) Sampling_method = 2 can make it slower. Try it out on one
frame first.

Roger that!
So umm... Sampling_method = 2, is that the same as +AM2..?

The documentation says it is. (actully Sampling_Method).

Yes, I use Moray and it writes and runs an INI file with the long version of
the command line commands. Sorry for the confusion.

doing just now. I noticed last night that my settings for TMPGEnc, were too

forgotten to set them back.) This can definitely cause flickering in
stationary objects. A real *Duh!* moment :-)
