Up-resing SD to HD
I've got a couple of old shorts, shot in SD (mastered on Digibeta). Can anyone recommend a cost-effective way of up-resing them to HD, with high quality interpolation? I'm not sure I have the gear to do this myself, so if anyone does the ability to do this, or knows of anyone, I'd be really grateful for the recommendation. I have a bit of money for this, but it won't stretch to big Soho facility rates. The films are 7 and 10 minutes long, and I'd want to end up with a ProRes file or equivalent. Many thanks!
