This thing is a terrible headeach! You´re right about what you said.
I render at 720x576 D1 Pal with 1.067 (this proportion gives the “extra” real width because PAL TVs are 4:3 in proportion,and 720:576 is not 4:3) But, like you said also, DVD architect doesn´t understand this, and i still get this side bars! It´s like as if it ignores the pixel ratio information (this is probably what happens). It´s the same when i put in c4d the 1.07 aspect ratio or not.
So i´ve tried Premiere Pro, wich now outputs to dvd (mpeg2 format) et voitla, i put this in DVD Archithect and now everything is ok. No Side bar.
Now, the strange part is that whether or not i render with the 1.07 aspect ratio (720x576 D1 Pal), if i import in After Effects it reads it with the 1.07 ratio. The thing is, that AE probably streches the video when no 1.07 ratio is present and this results in bad quality!!! You can note this very well if you have straight lines, that get all jagged up.
So, Lessons learned:
Render 720x576 Pal D1 with 1.07 aspect ratio.
- This way, my video has the same resolution as my Pal video projector
- No black side bars (the 1.07 ratio in the pixels fills the “missing space”)
- No quality loss in After Effects (or whatever) due to “streching”
Thanks once again everyone. Hope this helps future headeaches.
