Won't that then count up one by one? 00000000_000001.jpg through 99999999_999999.jpg ?
Reporting that it has several million frames if the first one is 20110101_010100.jpg and the last 20110103_235900.jpg ?
Or does it even get past the first one that isn't there?
How do I specify skips, to only use the frames at even one minute, ten minute, or one hour intervals, or other intervals?
I think all of these things are cleaner my way.
