enlarging footage

Postby EarthCurrent » Wed Jul 02, 2003 11:23 pm

I'm finally beating myself up with the actual editting of my Anime Tactics video, but I'm in a quandry. The only game footage that I am going to use in my lighthearted parody are the class name intros from FF: Tactics. Screen capture of one of the general sequences can seen below:

My problem is that, as you can see, the game footage is 320 x 224. The <a href="http://www.animemusicvideos.org/guides/avtech/avspostresize.html" target=_blank>Guides</a> go into shrinking footage and maintaining quality, but not really enlarging it and maintaining quality. I really don't want to try and work in my anime footage at that size, nor do I want my final product to be at that size either, so is there some clever way that I can enlarge this annoyingly small game footage and then clean it up so that it won't look ungodly with mad pixels.

Prepares himself for the general beatdown.

You can acheive relatively good results just by importing to Vdub and applying the Resize filter. Double the size to 640x480. Use the bicubic filter mode. It doesn't look that bad :P

Use avisynth's lanczosresize(640,480) or virtualdub's lanczos3 resizer, it's sharper than bicubic.

I did that...but pivelation gets pretty noticable in certain portions of the footage. Noticably the "page turn" a snapshot of which I didn't include. But a soften filter oversoftened things....

hmm...might be that I'll just go with the bicubic thingee...just wanted to test the waters and find out if there was a par-excellance way of resizing.

The guides say: "Lanczos Resize - excellent detail, but the sharpness comes at a price."

What exactly is this price? Does it slow down my computer? ...what?

The cost is compressibility. Sharper images require more bits to compress. Lanczos is a sharp resizing algorithm

:P oooooh


I don't know why I blanked out there...


I've used Lanczos, but it seemed too sharp. Atleast for the credits in MI2. Maybe since the text was already sharp, it made it look too sharp :P. Bicubic looked better in that instance.

you could blow it up to 4x the resoltion you want... apply a bunch of cleaning filters... the resize it to the resolution you want

when i work with game footage... that tends to be the best method for mixing and matching various resolutions cleanly
