Hi guys

I got an enquiry today from a UK TV production house that want to use one of
my images in a TV program.

Yay! But how should I render the image to make it suitable for broadcast?
Anybody else had to do this before (I assume yes) - what size / aspect
ratios / camera angles do you suggest to eventually get the best result
when it is broadcast and displayed on a TV screen?

Any pointers as regards copyrights, royalties, etc. etc.?

Hi Stefan,

usually, the traditional TV standards (NTSC, SECAM and PAL) feature low 
screen resolutions between 720H480V to 720H576V (horizontal/vertical) 
pixels. That means, your pictures don't need to be much bigger, unless they 
want to have a full-detailed camera move above it. If it is a plain display 
of your image, these screen resolutions should be okay.

But in any case, I suggest that you start a brief communication with them, 
as well. Whatever rules do exist in theory, the praxis of life can look 
quite different.

Here are some useful links:

http://kropla.com/tv.htm
http://www.digitalfernsehen.de/specials/df_12735.html (don't care for the 
language, just take the numbers of pixels, very easy)

Greetings,

Sven

Please
Can't you just make a reply to a post  so that your post cant be attached to
the post it refers to?
It would be obvious it is an answer.
"Answer" as topic could refer to any original post in a NG.

The References header serves well enough to identify the original post
that Sven's post is a reply to. If your newsreader does not show that
Sven's post is in reply to Stefan's, then I suggest you try a different
newsreader.

actually, I agree with M_a_r_c on this one

I really appreciate Sven's enthousiasm when trying to help other people, 
but changing the subject-line makes it, imho, a bit confusing :-/

Personaly, I would go for a resolution around 3 to 5 times the TV resolution's. This
will enable the 
producter to zoom in on some details if wanted. The effective screen aspect ratio is
4:3, even it 
the displayed pixels are not square, and your image's pixels probably don't need to
match the 
camera' ones.
Ask the productor how your images will be used: directly? printed and shown with a
camera? What 
dimentions are the best? TV stations have some prety cool image manipulation softwares
and 
hardwares. Those can do all sort if format convertions and manipulations.

Which, for an ordinary non-HD set is what? 460x200? I know it is very low,
compared to PC monitors, but how low?

As far as I can determine it will be displayed "1:1" full-screen, only for a
few seconds.

I'm currently thinking of supplying a 2600x1800 image that I've rendered,
this is much larger than anything they could possibly want, and they can
reduce and play with it as needed. Unless they ask for something else.
Thanks for the advice, anyway!

The easiest size that you can create and that they can deal with will be 
765*576 pixels. Set the aspect ratio to 4:3 as usual. Make sure you use 
reasonable anti-aliasing. If it is just a still picture, their video editors 
will do the rest.

If you are to supply an animation, or content for HD-TV or widescreen, 
things are different of course. In that case you should ask them firstwhat 
they prefer to dealwith, and if anything is unclear as far as configuring 
POV-Ray is concerned, ask here again with exactly what they specified.

Hmm,

honestly, I don't knew that there are newsreaders out there which lack the 
proper understanding of given structures.

I personally appreciate individual headlines as those give a first glimpse 
of an idea, what about the content of that posting is going to be. I found 
the boring and non-indicating repeating of the first headline as not very 
helpful. However, as I recognize that there are some weak or incomplete 
programs out there which cause frustration for some users, I am - of 
course - keeping from now the given headlines. Promise.
