Noah Apodaca1 has the answer for this one. Thanks for sharing!
ADS Pyro firewire DV bridge: this is an older unit that I don’t think is produced any more. You might be able to find one on eBay if you’re lucky. It’s a real swiss army knife of consumer inputs – lots of inputs to it, and it plays nicely with iMovie as well as Final Cut.
ADS Instant DVD for Mac: another older unit, this one has an onboard MPEG-1/2 converter, which makes it particularly appealing if I’m capturing video with no intent of editing, and I just want to author straight to DVD, or if I’m needing to output MPEG-1 to try to appease the dinosaur Windows user crowd (as MPEG-1 seems to be the only baseline of video compatibility over in their camp).
Pinnacle Video Capture For Mac: This is another hardware encoder, but encodes MPEG-4. This is great if I’m trying to capture a video that I’m not going to need to do much editing to (the supplied tools work fairly well for trimming, but not much else), and which I’m going to deliver straight to HTML 5, or straight for iPod viewing.
elgato EyeTV Hybrid: Using the dongle that others have mentioned, this can capture analog video as well, and the onboard editing tools in the EyeTV software are a little more robust in terms of making basic cuts and butt-edits. However, the timeline is not precise so when editing out commercials or glitches or whatnot, there’s usually a little bit more (or less) than what I want. I can edit in iMovie if I export, but I’d rather not take the extra lossy trip if I don’t have to.
my old, trusty Canon DV camera: this has a firewire output as well as analog inputs and can serve as a bridge directly into iMovie and Final Cut. Worst case scenario here, I record the analog source to DV, and then run DV to the Mac. Though this is the least elegant part of my rig, it pretty much always works and pretty much always works right.
If you can swing the financials, then definitely go with the ADVC-300, as previously mentioned. However, you can apply bargain solutions, but realize that they’re usually pretty inflexible, so know what they do before you implement them. If you’re good with getting what the bargain item will give, then you’ll be happy.
