Aspect Ratios: Converting 2.35:1 in MPEG Streamclip

[sarken.livejournal.com]

I've probably scared off more than a few people with the subject -- really, who wants to talk about aspect ratios? -- but I'm in a bit of a quandary. There's lots of discussion about converting 4:3 to 16:9 (or vice versa), but what about 2.35:1 and 16:9?

I'm on a Mac, so I'm using MPEG Streamclip to convert my VOB files. The majority of my footage is 16:9, but I have four clips that are 2.35:1. Ideally, I'd like to convert those to 16:9, but I can't even begin to guess at the the settings. Does anyone know how to convert from 2.35:1 to 16:9?

If there's no way to do this with MPEG Streamclip, my other idea is to scale the 2.23:1 footage up in Final Cut Express, so that those annoying black bars effectively disappear. I think that would work, but I'm not completely certain.

If you could offer some insight, I'd be very much in your debt. Thank you!
