#Aspect Ratio
5 messages in this thread
I'm putting my first steps in animation with a Targa+ 32 PAL.
1. I wonder if I render an animation to disk if I should use the Targa RDPADI
or render through the NULL device?
2. Secondly I have a question about the aspect ratio, I render at 512×576
(32bit) how should the aspect ratio be?
If I render at 740×576 (16bit) how should it be.
Do I always leave it at 1.0 ???
Thanks for any info
I'm not sure what the pixel aspects for PAL video are. You'll need to change
them, unless PAL uses a square pixel (I doubt it very seriously). For NTSC,
for instance, the 512×486 aspect would be 1.26 the formula for this NTSC pixel
aspect is (486\512)x1.333 – maybe there's a different one for PAL.
You can render through the NULL device, or the RDPADI, but I always render
null, because I use network rendering.

You have no idea where I could find the right formula build up for PAL???
Any one with experience or knowledge on this is welcome

From checking Martin's aspect of 1.5 for 512×576 it seems the formula I gave
you should work.

render to NULL but setup the right resolution 512×576!

My card reports back a aspect of 1.5 at that resolution!
>>If I render at 740×576 (16bit) how should it be.
Aspect 1.0.
If you are going to use fieldrendering, check out that the fieldorder is
right. I had to alter the standard value to FIELD-ORDER=0 for my TARGA+ to
get the fields in the right order.
I'm just in the middle of putting over a 5000 fieldrenderd frames that will
be a part of a company presentation on my Targa+ and Diaquest/Quickpass and
this setup works great. The only problem is finding a proper converter from
RGB to Y,R-Y,B-Y (BetacamSP) (-:!
