DVL-Digest 1097 - Postings: Index DVD camcorders - (2) Smallest 3 Chip Camera - (2) DVD camcorders - "Perry Mitchell" From: Crittenden, Jan DV is a interframe, or frame based codec, so that each frame stands independently. MPEG4 or 2 is an intraframe codec where it works within Groups of Pictures. While I don't know whether the cameras you saw were MPEG4 or MPEG2, most DVD today is MPEG2. So these cameras would be geared to the home hobby videophile as most professionals would find that not being able to edit on a frame by frame basis would be severely limiting. Also if you uncompressed the signal so that you could send it into an editing system, that used a different compression scheme, the concatenation of the multiple compression schemes would be very apparent, and for the most part unacceptable. DVD camcorders - "Perry Mitchell" From: Charos(Bill Carpenter) The billion dollar WTNH station down the road uses BetaSX with pretty good results. Even compared to amateur work such as mine :) Is WTNH's BetaSX Mpeg2 codec non-temporally based, or does their computer editing system deal with this using a computer to figure out the 'tweens? Smallest 3 Chip Camera - "Perry Mitchell" From: Jeff Hamman What is the SMALLEST 3 chip MiniDV camera one can buy? Am I correct in assuming it is the Sony DCR-TRV900? Smallest 3 Chip Camera - "Perry Mitchell" From: Perry Mitchell Since you asked, Toshiba make a 3 chip camera about the size of the TRV900 lens! It is widely used for special purposes such as car mounted rigs. (diese posts stammen von der DV-L Mailingliste - THX to Adam Wilt and Perry Mitchell :-) [up] |
