It would be nice to be able to pre-generate MetaData for large files. At the moment, what I do, is use the oflaDemo app - and it takes about two or three tries, and about a minute of patience. =)
As for the "enormous" meta files that Ben is seeing - they're probably that large because your FLV file has that many keyframes. That's what those entries are correlated to. Not knowing what the content of your video is (whether it's somewhat static, or very dynamic) you might try encoding them to do automatic keyframing, but if quality is an issue, then you might need to have all those keyframes. Also, what's the duration of one of these FLV files? I'm guessing from the meta file that it is about 57 minutes ...?
