Hi!

Swedish national television is having a contest where you can send in your 1
minute animations. Well, to keep it short Im thinking of giving it a go.

In their specifications they prefer the format to be in "720 * 576 Anamorph
or 1024 * 576 16:9 square pixel"

Ok, so I'm halted before I have even begun... I dunno what anamorph OR
square pixel means! Or, rephrased, which one of the above comes out of a
POV-Ray render?

Ehh.. yeah, I hope you understand my question... :/

With great expectations ;D

Umm... can this be on the right way..?

command line: +H576 +W1024

camera {
  location  <-58.0, 1.85, -58.0>
  direction 1.5*z
  up    <0,9,0>
  right  <16,0,0>
  look_at   <-5.0, 23.0,  4.0>
  angle 60
}

They are requesting mpeg encoding (right ?), with flagged pixel
ratio. (so, fine tune your encoding software, for them, that's all).

They are either expecting DVD native (Pal) definition (720 x 576) to
be displayed on 16:9 screen format, or basic computer screen (1024 x
 576, with square pixel ends up to a picture ratio of 16:9).

Remember to avoid the overscan zone in your production:
 - 10% near borders might be unseen (eaten by TV set)
 - 20% near border: no text/subtitle.

There is no problem for povray, has you can set the resolution
independantly of the view (for once, stay away of smart camera
settings using image_height/width).
So, make your camera ratio to 16:9, and either render at 720x576 or
1024x576 (depending on your encoder's capabilities: do some basic
testing, then make your choice).

You might appreciate some independant mpeg analysers to check your
setting.

Go!!! and good luck & fun!

Great, great! File should be in .mov oddly enough. Probably becasue they
will also post it online.

Thanks a lot for your fast reply and help!
