Hello folks,

I am creating a logo that I am going to mix with DV-PAL footage. What 
are the guidelines that I have to follow so that I get interlaced 
footage from a povray animation?

Thanks in advance

Fidel.

Perhaps someone else may come along and answer your question more
intelligently, but  you should remember that the output of povray is merely
a stack of bitmaps (BMP, TGA, PNG, etc.)  It's really up to you to figure
out how to turn these bitmaps into "footage" and I'm afraid I cannot help
you with your specific system.

Hi Greg, I have generated a dv-pal file and transfered to my camera, but 
the colours are too bright. It looks a bi weird.
I know that povray has something called field-rendering, but I don't 
really know how to use it.

It would be nice if someone could guide me.

Thanks in advance

Fidel.

With all due respect, and as far as I can see (and I'm not omniscient), you
are completely mistaken as to what POV-Ray is.  When we "render," it's
taking line of code like

sphere{z+clock*x, 0.1 pigment{red 1} finish{ambient 1}}

and turning it into a single bitmap.  There's also a way to do animations,
but the output of povray is then a stack of individual bitmaps, and you
have to use totally independent software to turn the stack of bitmaps into
a movie.

Take a look at

From: "Dennis Miller" <dhm### [at] attbicom>
Newsgroups: povray.animations
Subject: interlaced - which fields first?
Date: Fri, 8 Nov 2002 14:44:16 -0500
Message-ID: <3dcc141b$1@news.povray.org>
Xref: news.povray.org povray.animations:2309

maybe information in that thread is already sufficient.

In short, all you need is a program that can process the "interlaced" format
as output by POV-Ray.  Alternatively, especially if you only plan to have a
static image, you can just render it non-interlaced or depending on other
needs only render with 25 non-interlaced full frames per second, which will
be easier to set up.

Hi Thorsten,

Thanks a lot for the reply.

I have managed to sort it out with Final Cut Pro. Now what I was 
actually looking for you can find it here:

Once again, thanks a lot for the reply.

All the best

Fidel.

Hi Greg,

maybe you didn't understand my question. I know what povray is and what 
it does.

I am using povray on a Mac. Although I can generate movie files from 
povray scripts, I do generate a .tga sequence because I can put it 
together with another utility.
I had never generated movies to play on my TV, so hence my question.

There was once a debate about field rendering support on povray. That is 
  why I asked.

Anyway, I managed to sort it out with Final Cut Pro.

What I was looking for can be found here:

http://www.povray.org/documentation/view/127/

All the best

Fidel.
