Hi, I've just been playing and learning with the DVD backup guides and following the instructions along fairly well (big thanks to all), and I may have an idea for a usefull tool. Alot of the guides, and a lot of posts through the forum deal with setting the bitrate sizes when re-encoding with CCE (something I'm having trouble with right now... but that's another story). Anyway, I've been to Trilight's site and was noticing the formula he has posted there for figuring out how big you're final MPV can safely be. Namely, add up all the other VOBS etc, and any audio, sub streams, and then subtract that number from 4,700,000,000. That gives you your target end size for the main re-encode. Also, I've been battling with Scenarist and a DTS stream that pushed the bitrate too high. Again, I found answers here about adding your asset sizes together to figure out what your MAX bitrate should be when re-encoding. So.. my idea is this... 1) How about a tool that you can drag and drop (or point at a directory) that will total the files for you, let you select which VOBs to not include, and then give you a target size. and then one I think would be really usefull 2) A tool that will let you drop in (or again, point somewhere) your audio, and sub streams. The program will then analyze the streams and their bitrate settings, and then give you a safe MAX Bitrate size to use for your re-encode. Whadda ya think? and I hope I haven't posted this in the wrong section (sorry if I did).
