camera preset and HD reolution.

When you watch a motion picture film in HD 1080, its very likely that it has have been shot in a 35 mm motion picture camera. But the HD image has an aspect ratio of 1.77 and the 35mm camera has an aspect ratio of 1.33. So how is this problem fixed in film making?

This question brings me to this:
When rendering in HD, the divice aspect ratio must be 1.77 (render globals).
One should put the same value in the film aspect ratio (camera attributes) specially if tracking an HD (1080) footage.But waht if the footage was hot in a 35mm camera? if i set the preset of teh cam to 35mm academy then the aspect ratio will be 1.33. Whats the right workflow?

most normal film production is scanned from a 35mm negative to produce a 2048x1556 frame. This is the res you work at, often referred to as 2k. From this, depending on the screening format, you will either deliver the full 4:3 frame which is then cropped in prjection or you work with the full frame for a 1:85:1 (widescreen) projection. Because Blu-ray and DVD are such big markets now, it is very common to keep the 1.77:1 aspect ratio as a Safe for all work you do in feature film.

HD is 1920x1080 16:9 (which is 1778:1) if you are wokring HD then use that. If you are working full2k (2048x1556) then use that.
