Procedure for uprezzing 4x3 letterbox to 16x9

Export from a regular 4 x 3 timeline. After uprezzing bring them back in to a widescreen timeline and interpet the footage as 16 X 9. It works. I personally have changed as I mentioned above. The unsharp mask yields similar results.
 
I don't get this thread. We are talking about a simple 133,33% vertical resize. Editors do that. The 33% increase is very small in order to make an actual difference depending on algorithm. This type of resolution change cannot benefit from shappening. There are high end resizing algorithms and I happen to have implemented a few. They do make a difference for 200% or 300% scaling. But at 33% the advanced algorithms actually perform far worse than the simpler like bicubic due to artifacts of their sophisticated algorithms. Any tool that promises more resolution that what the camera took is bogus. This is not possible. The sharpening will hurt your already video-sharp file. A 33% scaling using any tool or editor that has bicubic resampling will do the job. No other processing is required.
 
very interesting.

would it be smart to say that this uprezzing would be good for landscapes and such (disjecta's beautiful work, for instance), but not so good for a narrative? does uprezzing make the image look too sharp for narratives?
 
I just revamp my website, so I thought I would let you know about the new link. If you want to upres your footage using Photoshop 7 or later I've got a how to as well as several PS actions you can download.

PZP does a much better job then PS, but if you already have PS and don't want to pay for PZP, then this is a great alternative. (But I would recommend splurging for PZP as it's only about $100.
 
I've been reading this and I'm a bit confused.

Isn't 720x480 already a 9:6 format?? (you just can't see it)
In other words when I edit I can see on either side of my footage information that isn't seen when I view it on a normal TV.

So is this what this is attempting to do... Shrink the normal footage you have to make it into a 9:6 format??
 
I'm not sure what you mean by 9:6?

If you are referring to 16:9, then no it is not. 720x480 is at a ratio of 1.5:1, where as 16:9 is at 1.777:1.
 
I am wondering id DVX has a really 16x9. Its seem fake for me. When I change into squeeze mode it seems that picture looses quality.
Can anyone help me out what to do if I need to film in 16x9. Is the answer only SQUEEZE which I do not like.

Nope, no 16:9. The camera is only 4:3. The 16:9 mode is just croping the pucture and then stretching it to fit a 16:9 area. So it is a fake 16:9.

Yep you are right. The inamge is being stretched in the camera, so it loses some resolution from doing so.

Your options are as follows-
1. Use the Panasonice 16:9 animorphic adapter (About $700 I think.)
2. Use squeeze mode.
3. Use the methods given at the begining of this thread.

Hope that helps.
 
I did a search for this and suprisingly did not find any answers.

Is it possible to use genuine fractals to do this? I've got the program, but I can't change the aspect ratio. I can only keep it in 4:3 and oh how I want that 16:9! I don't see any constrain proportions box to uncheck either so if anyone could help I would be more than happy.

Thanks!

You know I've sorta got it workin now, but I'm really not noticing much of a diffrence at all. I'm going to make up a DVD so I can compare the two on the television. We'll see how that works out.

just read through this thread. If you do use photozoom then whatever you do do not use S-spline.... use Catmull Rom (which contains its own form of sharpening) and turn off an unsharp mask filter. Definitely do NOT add in extra detail !

I'm sure that PhotoZoom uses unsharp mask. No 'magic' at all.

I think this uprezzing is unnessesary and time consuming. Same results with letterboxed 4:3 with unsharp mask added.
Some DVD players and TV sets have similar algorithm for 'sharpening' video and most picture editors have this effect.
Even MPEG2 encoders like TMPGEnc, Canopus ProCoder, Adobe MediaEncoder can do this alot faster than Photozoom.
And more: when we export TIFF files from editor then (lossy) DV codec is unpacked. After processing in PhotoZoom we
have to pack this again to DV (if MPEG encoder doesn't support image sequencies)... meaning quality loss.
Maybe I missed something?

Where would be the unsharp mask in PP1.5
 
Im working with FCP 5 and it looks like when you drop the widescreen Tiff files onto the timeline you have to manually put each frame at 1 second to make it run at normal speed? Am i missing something because that would suck to do on like a feature film! :)

You could do it that way- and your right, that would suck! But I would recommend doing the following:
Go to Final Cut Pro - User Preferences - Editing and then chage the Still / Freeze Duration to 00:00:00:01 (One frame)
Now you'll be set, and when you import any still into FCP it will be one frame, and you do not have to change it manually.
Hope that help.
 
Has anybody yet tried this with Progressive footage? Just curious because I'd like to definetly use this, but only if it works with either 24P or 24PA.

Yep, and it works great. That is what this thread is all about. Give it a try,, I think you'll be happy with the results.
 
Hi
have read through the whole of this great thread but don't think it helps my problem. I have 4x3 INTERLACED footage which needs to be edited for viewing on a 16x9 42inch plasma screen in a museum. i'm getting that this technique works for progressive footage but does anyone know how i can achieve decent results uprezzing to 16x9 interlaced? it's pal footage using pp 1.5
Can anyone help me, got to start edit tomorrow?

This process is format agnostic. In other words, it doesn't care if you have progressive, interlaced, NTSC, PAL, or whatever. All you need for it to work is a still image sequence- like tiff's. Export from you NLE an image sequence of your finished cut, and then let PZP do the rest with the up-resing. (I'd tell you how to export, but I have FCP, not PP1.5)

Hope that helps.
