Someone had asked off-list for advice on 2 things: PAL<-->NTSC (using Cleaner) and combining avi files (I think). At any rate I accidentally trashed the Inbox here, so there we go: Cleaner involves a two-stage process that is lengthy, to say the least (and have a huge clean firewire drive while you're at it, too, it'll turn a PAL-based avi of 650MBs into 4.5 Gigs before you know it)). There are a couple of alternatives (several): ffmpegX, Main Concept Encoder, and MPEG2 Works version 4. ffmpegX is a terrific app, but the PAL/NTSC conversion is not its strong suit. (there are audio/video sync probs there) Main Concept is great. it's also $250 US. And it does batch conversions. MPEG2Works does amazing PAL/NTSC (both ways) conversions, and is nearly perfect where synced audio/video is concerned. It is 30% slower (on average) than Main Concept (not a bad tradeoff for the sync quality) and it is ten times cheaper: $25. <--the winner All of these will join avi files (I think it's on the Tools tab in ffmpegX) but there's another 20 dollar shareware app that is the great joiner, and that is JFUSE ( http://jfuse.com ) and it'll join multiple files as opposed to ffmpegX's max of two at a time. There are other unix-based joiners out there, but they rarely work in terms that QuickTime (for example) can process properly (for playback) . You'll see a huge MB-sized file, a QT icon, but the playback halts after what would have been the first 'segment'.... a no go. With JFUSE it's just select, join, showtime. Period. So, JFUSE to join, MPEG2Works4 to process the conversion. MPEG2Works still supports several previous versions, so no matter how old the Titanium, or which OS, there's one out there. My advice: get the latest, unless you work in OS 9. brian s
