I have limited hands on...I would imagine any of the Lancoz packages should be ok, however, scaling, up or down, can add artifacts. The scaling software is making decisions as to what are edges and how they should be represented.

It seems that the super resolution is the least expensive way to get a solid scaling algorithm. However, it would seem that that from a scaling perspective, it is similar to Magic Bullet HD Advanced. There are some other good algorithms out there in addition to Lancoz.

Things to look for are lines, especially repeating lines (e.g., picket fence) in an angle, curves, and artificial edge sharpening.

Note that this is part of the 'RED' advantage. Like the GH1 it is oversampled. In the GH1 the images are demosiced and downscaled in the camera in realtime. In the RED the demosaic and downscaling is done in post on a more powerful processor without realtime constraints. The SK2i demosaics in post, but the captured image is a direct 1080p.
 
thx for the info

I only have a tiny budget for the film so a $99 option to stretch my anamorphic footage is attractive. The alternative is to just crop the 16x9 to get 2.39:1 but @ 720p it doesn't leave me with a lot of pixels for the 35mm transfer. Plus no cool distortions or lens flares.
 
Do you really think the anamorphic is worth it? In the old days, it turned 4:3 into 16:9, but had lots of issues. There are many DVX threads on that. An HD anamorphic lens has to be pricey. Why not just spend the effort on grip equipment and sound to a get a feel more than a look?
 
in two words 'Blade Runner' yeah it's worth it. A lot more work but with a GH1 it's ridiculously inexpensive so I have to try it. I'll study some of the issues threads first though.
 
video enhancer, in my tests was really buggy. I think one guy posted on their
forum, that it was total shi*, he was so pissed. :Drogar-Love(DBG): It can be frustrating.

The others have different degrees of hassle setting up. Trying to crop what you
get seems problematic too. try the demos is best.

I really dont think this "uprez from 720-60p" is a good workflow for a big project.
Not on the options I've seen.

You might rather spend your days sand papering your eyeballs and swallowing
paint thinner.

try and make your 1080 work!

sounds like just the thing I need to stretch my anamorphic footage, thx.

What kind of anamorphic stuff is it? Some years ago I made a lot of upscaling 16:9, 25p SD-DV (anamorphic) to 1280-720/25p. Resizer 2 made a good job. It was hard to distinguish from normal 720p. And anamorphic HDV (1440x1080) doesn´t need a resizer anyway. Maybe now the latest version of "InstantHD" is somewhat better, I don´t know.

Hey capice can you just use it to anti-alias the 1080 footage?

I don´t think so. But didn´t give it a try so far.
 
I'm thinking of shooting 720p with a 1.5x anamorphic lens then stretching it 1.5x and cropping it to get 2.39:1 so it would end up 1720x720

Interesting.

I know nothing about this. Im just curious if a simlar effect could be got
by changing the pixel aspect ratio to a custom size?

Of course one wonders what type of distribution you hope for?

I recently saw a version of How the West was won. shot in 3 camera, CINERAMA.
Talk about wide! This was the rolls royce of wide.

The dvd has two versions, apparently, One letterboxed, and one with a smiley
shaped image. Really distorted.

High sides, thinner in the middle. Strange to watch.
