actually this is from the first version of photozoom. (i guess) packaged with photomagic. i resized to 2048x868. i could've used 1024x434, but just wanted to see how the larger would turn out. anyway here's the original:

first go round:

scene22cc.jpg


last attempt:

scene22cc3.jpg


and here's a part of the actual size:

all i need now is to run a few frames and test it on a monitor or projector and see what it looks like blown up.
 
well here's what it looked like when i resized it on paint shop pro:

i'll post a clip over the weekend once i batch process enough frames :) the coloring is different, but it's also a bit softer. i used various sharpness settings, but they all added artifacts/grain. to me photozoom turns out remarkably better.
 
As one of the developers of PhotoZoom, I'm happy to see that people appreciate the advantage that our software offers. But may I recommend also trying PhotoZoom Pro 2, as it contains some major improvements over the original PhotoZoom :)

Especially our new S-Spline XL algorithm that was introduced in PhotoZoom Pro 2 should produce even better results.

How does this work? It's not just scaling the image, right? Does it add pixels somehow?

Scaling is adding pixels :)

But it's the "somehow" that matters. Scaling/enlarging images requires interpolation, and there are several methods to do so. The most common is probably Bicubic interpolation which is also in Photoshop, Paint Shop Pro, Premiere and many others. But it results in jagged edges and blurring, as you will probably have noticed if you ever increased an image e.g. 200-400%

PhotoZoom Pro 2 offers a patented interpolation algorithm (S-Spline and the improved variant S-Spline XL) which was developed to overcome these problems. It also depends on the quality of the original image, if it's completely blurred or contains no detail or sharp edges, there's not much to gain. But if you have source material of reasonable quality, the difference between interpolation results can be quite impressive.
 
i want me some photozoom 2

how does it do when you take regular 4x3 footage and uprezz it HD ?
 
first rogier i am getting photozoom pro 2...i just have to wait a pay period...one word for you...christmas :)

papa and lake films...

that is 4:3 footage i started off with. i cropped it in premiere and then resized in photozoom. the way i cropped i posted here.

if you weren't going for the "scope" look and just straight widescreen. then say you shot either anamorphic or squeeze then export frames (TIFFs). batch process those in photozoom and resize to either 1280x720 or 1920x1080. the difference between the version i have and Photozoom Pro 2...there are more controls, batch processing, and as rogier said the algorithm has been improved.

Benvista offers a trial version that watermarks the output, but you'll definitely be impressed by what you see.

and no i don't work for them :)
 
okay after a long bout with...ah never mind...

original out of premiere:
scene12p001.jpg

cropped in paint shop pro:
scene12up001.jpg

uprez in photozoom(click picture for actual size):


now the problem...i made mov and wmv files. when i first made the mov file i was a bit appalled at the crazy banding in the shading, but then when i saw it also occured in the wmv file. i figured it was something i did on my end. i must say though that the jpeg2000 file turned out great (albeit huge) along with the some other codecs i used. so here's the link:

Scene 12

i think i know what caused it and will do some further testing.

EDIT:::

okay i'm seeing it now on the pics i posted and oddly it's not on my files on my hard drive. the very files i just uploaded...hmmm.

EDIT AGAIN:::

hmm the pics look fine here at my parents house...so i eitehr have suck monitors or something is affecting playback. going to test and see.
