I'm trying to create a slide show for a friend of mine that owns a portable outdoor cinema screen and dvd player. She needs to have the slide show with an aspect ratio of 2.35:1 (anamorphic). I've done lots of research and I can't make heads or tails of it.
Here is what I know. In the past in order to create a non-square pixel image in photoshop for dvd you need 1st create or crop image to 720x540 pixels. Then when you brought it into Final Cut or After Effects you could squeeze the pixels on output to 720x480.
What is the correct amout of pixels for 2.35:1 (anamorphic) image in photoshop (i.e 720x? or 800x?) ? Is the 2.35:1 pixels square or non-square pixel aspect ratio? In photoshop CS2 I see 720x480 or 720x480 (widescreen), one uses .9 aspect ratio and the widescreen uses 1.2 - what does the 2.35 (anamorphic) use?
Could someone give me a basic understanding and a possible place to start?
