Here is a big stupid question i want to ask... Is it possible to uprez 60i anamorphic material played back at 24fps? (slow motion footage) Every field turns into a frame of less resolution... so will the same apply to this?

Ok I have been thru all the threads looking for TIFF .I would really like to try this but at the moment I am having issues trying to export footage from my time line as TIFF. I am using Pinnacle Studio 9 Plus and it only exports ..STE files , so I tried LE6.. nope...Then I tried Premier Pro ( trial veresion ) Nope ..No TIFF file ....Ok I see Vegas doesn't export TIFF as well ..Any ideas ....Thanks for the help with this ....Ian

Do you mean you want a 2.35 letterboxed version? Or two separate versions, one with dimensions of 2.35:1 and the other with dimensions of 16:9?

Sorry if these two questions have been answered -- I think I've read most of this thread and didn't find them specifically...
1) Say I shoot letterbox and uprez using photozoom. Then I create a widescreen DVD. If I playback on a 4x3 TV, the DVD player is going to shrink again and letterbox. Have I just LOST quality over simply leaving it letterboxed to begin with?
3) Say I can't afford photozoom right now, and I want to uprez some letterbox footage to match some other squeeze footage that I have. If I uprez the letterbox stuff with a bicubic or b-spline filter (e.g. using photoshop), I know that I will not have achieved the quality of the photozoom method, but will the quality actually be WORSE than the squeeze mode footage? Noticeably, or just subtly?
(I would like to have a true widescreen release of my project for future possibilities, but right now, 99.99% of my audience is going to be seeing it on a 4x3 display. So far, due to indecision/experimentation, about half of my footage is in letterbox and half is in squeeze. I need to make a friggin' decision and stick with it, but I am also going to need to be doing SOME kind of conversion at some point because of the mixed footage...)
Thanks for your help!

Spidey -
It would be the same quality as though you had shot in 4:3, composed for 16:9, and used PhotoZoom to uprez it. You'll just have black bars on the top and bottom of the 16:9 image - so your picture will be shorter, is all.

I think you might as well leave your footage in 4:3. You can always create a master from Photozoomed 16:9 if you want, but give out copies in 4:3 Letterboxed, if that's what you'll mostly need. Nothing's stopping you from doing the up-rez in ten years if you want to, right?
As for the bicubic uprezzing - I don't know if it would be worse or better, you'd really have to do a test yourself. My guess is that it might be a bit softer, but probably wouldn't look considerably worse unless you were watching it on a very large output (a big-screen HDTV or via projection). It probably would be easier, though, and definitely higher quality with 4:3 displays, if you just downsampled the squeeze mode footage to 4:3, and left the letterboxed footage alone.

It would look like the 4:3 uprezzed to 16:9 footage, only with bars on the top and bottom. The quality itself, pixel to pixel, would be exactly the same as though you had composed for 16:9.

Well the answer you want is entirely subjective

Well it will work the same as the the 16:9 method, only with bigger bars. If you like the bars, and the quality is fine for you when you uprez regular 16:9 footage, you'll be okay. Might be a good idea to just transfer a small section to DVD, first - and see if it's to your liking.

I believe that you'll need QT Pro inorder to do what you need. Here is how you do it:
- Put all of the TIFFs into one folder seperate from any other files.
- Open Quick Time.
- Go to: FILE - OPEN IMAGE SEQUENCE
- Select the folder that has the images in them.
- (After it has opened) Save the new file as an MOV file.
Hope that helps.

Well, Sledgeweb, Shooter, and myself have been playing with different methods of stretching the image to get 16:9 (Uprezed from 4:3). (We used Photozoom Pro, Final Cut Pro, After Effects, and Photoshop.) You can check out the results at this thread:

As for your question about bicubic processing, according to Ken Bennett, if done in small amounts (8 - 10%) it works great. I tried to find his original article on the net, but all I could find was this: http://users.wfu.edu/bennettk/sharp.html .
I do have an archived PDF of the article, which you can download here: (Right click, Download/Save As)
