   im well familiar with the technical differnece between interlaced and progressive frames and that alot of pro-sumer cameras offer a choice whilst shooting. my question:
   has anyone heard of people recomending you shoot intrelaced insted of progressive becouse it gives you better film-like quality in post?
   
   if so, why/how? thanx!

   Hey, Jay, Interlaced video consists of two fields that are merged to make one frame. These fields help make your video look really smooth and fluid. It also makes your video look like video. Progressive frames are simply the entire frame of video (non-interlaced). Progressive video playback is not as smooth, giving what many people say is a film-like look. All camcorders shoot progressive video, but a few camcorders Canon can shoot interlaced and 30 frames per second. And then Panasonic makes the DVX100, which can shoot 24 frames per second (just like film) progressive mode. It does a reverse 3:2 pull down in camera and bumps that 24p to 30fps before it lays the image to tape. This is an awesome camear and really creates beautiful film-like images.

   All video cameras should shoot interlaced footage. Some special cameras can shoot progressive footage.

   Rick, i think you got it backwards. While your right that interlaced consists of two fields, it does not give you more of the "film" look and all camcorders donot shoot progressive, all of them shoot interlaced video. this is your standard NTSC 30 fps video. You're also correct that progressive is one whole shot instead of two fields woven together. but think about this. Film is a series of whole shots. Not interlaced. On a TV, every other line of television is scaned (one field) and half a second later, the rest of the lines are scaned. therefore, there are two fields per frame and 30 frames per second. In progressive, there are 30 full frames per second. Progressive is more of the film look and is much better quality. HDTV is progressive while standard tv is interlaced. Of course, for the real film look you will need to shoot in 24 frame progressive.
   
   Personally, i'm unconvinced that the "film look" can be achieved using a prosumer lever digital video camera. the way a CCD renders light is much different from that of film.

   (I'm pretty sure i got my technical specs right, however, i might be wrong. either way, progressive is much more like film than interlaced)

   Most movie dvd's that you watch on your home dvd players are interlaced and the dvd player and or projection or lcd/plasma can recieve a progressive conversion created by you dvd player. More stuff to confuse everyone!
