At this moment I am rendering a video I did about 14 years ago or so.
(before YouTube...)
See: https://www.youtube.com/watch?v=s0o0fgmyYYk
This remake will be in Full HD 1920 x 1080 pixels and at 30 fps.
The total video takes 10920 frames, so it will take a while :-)
I render with AA = 0.3 and Q = 9
And now for the questions:
I understand that you can let Povray render a 32 bpp image R G B + transparency
PNG file.
To do so I used:
Output_Alpha = 1
and I changed my background to:
background
{
rgb < 0.8 0.8 0.6 >
transmit 1.0
}
It looks like it works:
- the output file is a little bigger.
- when I view the output in Irfanview and select the Alpha Channel I see my
object ( a Piston) in white on (If I remember well) a black background.
QUESTION:
- Am I correct to assume that Povray only makes the rays that DO NOT hit an
object transparent?
- If I specify a greenish background and that colour also appears in my
rendering, is ONLY the background transparent? Or also part of my rendering.
- How can I use a series of Povray images to create an animation?
- - Years ago I used VideoMach. Are there better tools?
- - Are there tools to merge my animation with another video?
What I would like is a way to show my animation 'in front' of another video.
Like Blue or Green screen technique used for film and TV.
Any help is much appreciated,
