I am just making a video

1280x720   16:9     30 frames per second

The big question is, what Video Codec
is best for output.

I make much use of

#declare Nature_t_Madow = texture
{ pigment
   { bozo
     turbulence 0.3
     color_map
     { // dry gras
       [0.000 0.300  color red 0.40 green 0.90 blue 0.00
	            color red 0.30 green 1.00 blue 0.00]
       // normal gras
       [0.300 0.900  color red 0.30 green 1.00 blue 0.00
                     color red 0.20 green 1.00 blue 0.00]
       // green from flowers
       [0.900 1.001  color red 0.20 green 1.00 blue 0.00
                     color red 0.05 green 0.95 blue 0.00]
     }  // color_map
   }  // pigment
}  // texture

to give surfaces some structure.

For the mixing of the video, I use
Magix Video Deluxe 2008.
I can not test all codecs, because only a limited
number of Codecs can be taken.

Please some advice

Regardless what Codec, it's flickering
where are to hard contrasts.

before  I used GEMINI_t_Aluminium for the photovoltaic frame,
now GEMINI_t_Frame to reduce contrast.

Hope this reduces the flickering when the lines with the
frames move in the video

#declare GEMINI_t_PV_Silizium = // normal silizium photovoltaik
texture
{ pigment { color red 0.40 green 0.00 blue 0.60 }
   finish
   { brilliance 8.0
     phong 0.8
     phong_size 16
     reflection 0.1
     ambient 0.1 + Nature_m_ambient_add
   }  // finish
}  // texture

#declare GEMINI_t_Aluminium =
texture
{ pigment { color red 0.51 green 0.69 blue 0.70 }
   finish
   { brilliance 8.0
     phong 1.0
     phong_size 80
     reflection 0.5
     ambient 0.1 + Nature_m_ambient_add
   }  // finish
}  // texture

{ pigment { color red 0.408 green 0.552 blue 0.560 }

     phong_size 80
     reflection 0.3
     ambient 0.1 + Nature_m_ambient_add
   }  // finish
}  // texture

  Any codec implementing H.264 is usually a safe bet. (Although with some
inputs it may require some tuning of the compression parameters to get a
good result.)
