How Dartmouth Produces Video Podcasts

And a 8,000 U.S. dollars investment, Dartmouth Department of Physics and Astronomy has established the ability to provide video podcasts of courses to enable students to watch the talks, they may have missed or worthy of review. Now, that the LABs general manager Yuehan La Ghent, New Hampshire, the new school is exploring how it can capture the existing campus speech wide.up, until the summer of 2004, only a single professor in the Ministry is in practice, so that one of his courses available to watch after class. Media format video, which to check from library.video capture technologywith seed money in hand and recommendations on the basis of the AV other groups on campus, Largent gl2 investment in the Canon camera. Minidv tape but its limited him to one hour of recording time, there was not enough capacity for the talks, he needs to capture. He switched to the 80-minute tape, and then added: focus on strengthening the firestore Financial Secretary - 4 portable dte records to the combination. Financial Secretary - 4 can capture three hours - about 4 0 gigabytes - the value of video content. Tape is only as a backup to the Financial Secretary - 4 and, vice versa. If the tape in the camera during the filming exhausted, the Financial Secretary - 4 to recording.now Largent from a lecture, do not have to download the video to another store first. Or even better, the time occupied by the post-production work has been shrinking considerably.he hook the Financial Secretary - 4 of his iMac and whether there is a file transfer will take about five minutes. Financial Secretary - 4 savings talks in 10 minutes of clips, Largent use Apples Final Cut Express HD in the clips together and edit the "Conference on," Professor Fan spent five or 10 minutes , In the classroom students work on a problem. That is, it takes another five or 10 minutes.

Largest consumer of time, Largent said, is compressed. "We made. Mov file to the iPod m4v format." Compressed files, from 11 [gigabytes] to 12 gigabytes down to a file of 700 [megabytes] 800 megabytes, small enough to play on an iPod. One hour of talks, took about four hours, compressed hours, until the G5 Largent products of non-Intel CPU deal for Intel chips, led by computer processing power, so that it can do so in time compression 2 hours.he said that he hopes to reduce this is by increasing the use of the computers Xgrid, Apples distributed computing tools. "If other computers in the Department have opened, the computer is doing all the compression, in fact, the use of these computers to do [work]," Largent said. "It can reduce one hour of video compression to 20 minutes .... then we can have talks, set up on the Internet, one hour after the talks contrary."
