Yet Another Up-rez question...sorry

Hey Everybody,

I know the whole 4x3-16x9 topic is getting old but, I had an idea the other day. Let's say I had a editing suite that had a 2.35:1 timeline. Now if I knew the exact measurments, Could I, using Photozoom, stretch my 4x3 footage to 2.35:1 and then drop it in a timeline that will support it? I suppose one problem would be burning a 2.35:1 dvd, but I'm still curious.

Thanks

Only because there's no such thing. :)

Seriously. DVDs/TVs give you two options: 4:3 & 16:9

Anything that shows in other aspect ratios like 2.35:1 or 2.40:1 or whatever, are just letterboxed down to that.

You could calculate the pixel aspect ratio to make it really 2.35:1, but that would just result in a distorted image on the screen.

You can do the uprez thing to make it 2.35:1 (you'll need to find someone better at math than I am), but you'll still have to drop it into a 16:9 timeline, letterboxed to fill in the empty space. (Or maybe not...it should already be black...but it might not be the right color black for TV display, resulting in a two-tone letterbox on the screen.)
 
GenJerDan,

Thanks for the reply, although thanks to your info you've opened a new realm of questions that I have. But I won't bother you with them, I just wish that I could figure out the math so I could at least test it out.
 
2.35:1 is either 720x306 or 720x360 (But I can never remember which is square pixles for computers, and which is rectangular pixels for TV). That should get you started, though.
 
On a 16x9 timeline, you are basically chopping off 12.5% of the top and 12.5% of the bottom to approximate 2:35:1

On a 4x3 timeline, you would chop 25% of the top and 25% of the bottom.

It's not exact but close enough. I use 'scope ratio almost exclusively for my films and that's the formula I work with.
 
So now that the 100B, if I read correctly, unsqueezes squeeze mode in the LCD and viewfinder displays, is there still a reason to shoot letterboxed with it.
 
Letterbox is for when you're going to show your footage on a 4:3 TV, but you want it to have that widescreen look.

Squeeze mode will not display properly on a 4:3 TV.

(if you burn it to a DVD though, the DVD player will take care of converting the aspect ratio for you).
 
You must have answered that question so often that a part of your brain must be feeling completely numb.

I am both sorry and thankfull.

Disjecta... Do you shoot with a 19:9 conversion lens, or do you uprez? What's your method. Your films are amazing!

Thanks for the kind words. I shoot in letterbox mode and then uprez as documented in the tutorial in this forum.
 
disjecta, do you crop your image in your NLE before using PhotoZoom? I'm having problems cropping to get the right aspect ratio (16:9) on export.
 
I'm sorry guys,

I just want to make sure I got this down so I don't bother any of you any longer. So please tell me if I got this right.

1. Shoot my footage in letterbox.

2. Once editing, save movie a tiff files.

3. Follow disjecta's directions for up-rezzing to 16:9, only change pixles to 720x 306 or 360.

4. Drop in image sequence on a 16:9 timeline and render as 16:9

5. Throw it all on a 16:9 DVD and hope it looks alright.
