Yet Another Up-rez question...sorry

[Rob9]

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.

[GenJerDan]

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.

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

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.

[Barry_Green]

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).

[Alekan]

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.

Thanks for the kind words. I shoot in letterbox mode and then uprez as documented in the tutorial in this forum.
