I'm interested in slow motion capture in either a SD or HD camcorder. I've been looking at the Samsung HMX20 but even though it's a 1080p camcorder the slow motion mode has a resolution under half of SD camcorders which is a concern. My budget is £500 maximum and I'd prefer a HD camcorder but if the slow motion facility is poorly implemented on a HD cam I'd prefer an SD cam with a better implementation. I've seen a Sony HD camcorder that offers slow motion but only for 3 seconds which is useless; at least the Samsung lasts longer than that. Any ideas?
