Widescreen Sizes

[mattmatheson]

Ok what I've been doing for shooting widescreen is I shoot letterbox to help my framing, I know I could use rubber bands and all that but thats not what I am asking, after I captured the first day I got my cam I took a frame out and took it in to photoshop an made a psd of just the bars on top and bottom, what size would be for like theatrical type widescreen? What size is what I am asking, I want to keep it 720 in width so what height would I use.

Just divide 720 with whatever ratio you want.

16:9 = 1.78
Academy = 1.85
Cinemascope = 2.35 (or 2.40)

So for academy you want a frame 389 pixels high. Remember this is with a PAR of .909 for NTSC DV.

720X404 = 16X9
720X390 = 1.85:1
720X306 = 2.35:1 (cinemascope)

found this while doing some other research just now

To find each aspect ratio in pixels.

720 divided by aspect ratio, multiplied by 1.

So 720/1.85 = 390 X's1 = 390

720 X 390

for 16X9
720 divided by 16 times 9
or
720 divided by 16, then times 9
