• | 720x405 Why?

Hi!
Does anyone know why 720x405 is the right aspect ratio for true 16:9?
I have a anamorphic video and in some frames a circle appear. When i convert these frames to 720x405 the circle becomes oval.
But when i convert to 720x432 the circle gets it right shape.
If you multiply (PAL) 576*0.75 you get 432. Doesn´t that sounds more correct?
I appreciate all comments and help!!

720x405 is 16:9 square pixel:
16/9 = 1.78 (1.7777777777778)
720/405 = 1.78
405x1.78 = 720.9
720/1.78 = 404.9
What or where is your source from?
Generally speaking, are you working in PAL or NTSC?
What are you delivering to?

I´m working in PAL and delivering the video as hi-res QT.
Thanks for your help!

Ok, but 720x405 is not a PAL resolution. Where did the clip(s) come from?

The source video is PAL 720x576 anamorphic. The client want the files as widescreen. Thats why im asking.

Then you could give him 1024x576 square pixels, or 720x576 non-square or 720x405 square pixels.
It all depends on what your client wants to do with the material?

For viewing on a (Widescreen) TV you should be delivering 720x576 non-square.
