Movie splitter is a fast and easy-to-use video trimming and splitting program. Cut and save your favorite episodes from a series or split a large file into individual segments to burn on CD or DVD. Split, cut and trim AVI, MPEG, MOV, ASF, and WMV video files. Save split video fragments to AVI, MPEG, RM or WMV. Split your video automatically by size, duration or number of segments. Cut your video manually, selecting the start and end points for each segment. Select as many video fragments as you like, including the intersecting fragments. Save time with our new unique fast-splitting technology. Don’t sacrifice video quality – save to AVI and MPEG without recompression.

finally the perfect solution pour webmasters:

super directory submitter Website Submitter
is a program designed to submit your web page to thousands 20 000
of higher Quality directories. It will save you a lot of time, effort and money since its fully semi-automated. You just enter some information about your web page and the program does the rest. With SDS software you will never need to search for places to advertise again.

The tricky part would be writing an app (or finding some existing code – I’m thinking something like ffmpeg) which then muxes those chunks together into a single MP4 file. A lot of MP4 parsers don’t implement the fragmented format, so you’d probably need to also rearrange the media data into a single box for greater compatibility, in order to get a vanilla MP4 file.

Is there a way to play the chunks without silverlight? E.g. downloading all the chunks of a selected bit-rate.
