DVD 4.3 and 16.9
by Dean Markey on Oct 12, 2008 at 7:40:16 pm

Hi, does anyone know if i can set a comp in after effects to a to produce a video that can viewed on both pal 4.3 and 16.9 screens and always maintain a cinema style letterbox effects.

I would like to keep the letterbox effect as i would like subs in this area, also all of the original material has been produced in comps at 1024*576 square pixel, the master comps hold material of mixed content such as 3D rendered stills, real video, stills and after effects fx and text..

Does anyone know a good work flow from material produced at 1024*576 square pixel to 16.9 DVD played aimed for both 4.3 and 16.9 monitors and maintain a letterbox that can hold subtitles?

thanks for your replies...

You'll need to put both versions onto the DVD and have a menu where either version can be selected by the viewer.

1024x576 is PAL 16:9. So you'll have to nest that and then letterbox it to suit your needs.

For the 4:3 letterboxed version, just nest the 16:9 comp into a normal 4:3 comp and scale width and height by 75% to get a letterboxed version.

Thank you for the reply,

Yes, i was working along those lines you suggested. Problem i have found is the nesting* with the 1024*576 if i make a comp in AE pal dvd size and next my comp into it the image is pixelated, i have been using 1024*576 square pixel for all of my AE comps. If i export from AE direct from this comp size and import to encore it reads it as 16.9 and all looks fine but i wont be able to add text in the letterbox area...

no solution for this i think... do you?

I believe that you have used the term pixelation incorrectly. Pixelation is used to describe that artefact that results from scaling up a raster image beyond its original size resulting in enlarged pixels.

Therefore, if you nest your 1024x576 comp into a 720x576 comp, you shouldn't see any pixelation. What I am assuming that you see is in fact a squashed image due to you resizing the 1024x576 nested comp to fit into the 720x576 comp. If you did this, then you are wrong.

WHen you nest the 1024x576 comp into the 720x576 comp, you shouldn't resize anything. The end result is that you will lose the edges of your 1024x576 comp. Perform a Google using the keywords, pan-scan & DVD to get a better idea on pan and scan techniques.
