Shake has a pretty powerful resizing feature when importing footage, complete with anti-aliasing any jaggies that might result, and it does a good job of boosting detail without boosting any grain your footage might have.
The trial version features full, non-watermarked, rendering capabilities. You just can't save, but since what you need to do only requires a couple clicks, and changing a few settings I don't think you'll be needing the save feature.
Re: Instant HD - resize Beta to HD pixel dimensions by RoRK on Aug 16, 2006 at 2:43:38 am
I've only tested one uprezzing software and that's Instant HD. It's not magic but it's ok for most stuff. Where it fails and I expect where others will also fail is with graphics with alpha channels. On live video, they should be fine. And Instant HD works only with progressive frames. If you have interlaced footage, then you'll need to convert them to progressive first. The Instant HD manual covers this step. You may also want to look at digital anarchy's Resizer plugin. And then there's one from algolith although they never replied to my enquiries on receiving a demo version.
