hiya peeps, as a first year IT student ive got to do a report on, vid capturing, i dunno anything about the subject yet, besides that its got to do with recording images and stuff.
now i was wondering if you peeps know any good places i coud go to get more info on the subject or maybe you know something more about it? any info is wellcome.
its gonna have to be a 15 pages (minimal) report and its gotta be hardware related to vid capturing, not software related. |

I know a fair bit on the subject.
Video Capturing involves a video stream being converted from analog (usually) sources like VCR etc and converting that into Digital format and recording that on your computer.
from there it can be either compressed down from straight AVI (thats whats usually done) as uncompressed avi is huge and compress it as something like mpg or in divx format which is incredibly small comparitively.
I'd search in google for video capture or see if www.tomshardware.com or www.anandtech.com has anything on it |

| ah thats a start, well i tryd google and that comes with with first 3 pages full of adventisements of all sords, but never explains in detail what vid capturing is and what hardware is used for it etc. |

This ain't for any help, but don't you have like literature and set books that you're supposed to read?
However, you should make yourself comfortable with google and use it all the time, it can take you anywhere!
www.vcdguide.com and divx.vcdguide.com are the two oldest urls I know of :) |

A video capture card is the hardware used. the more expensive the more it can do in "hardware" as opposed to much slower software. So a high end pinnacle capture card has a built in mpeg2 encoder/decoder built in which allows the capture card to convert raw avi (which is huge to compressed mpg video in real time. As you play the input it does the conversion and saves it on your HDD. So if you had a cheap card it would have to be saved on your HDD first and then you'd have to open a video editing program like Adobe Premier and save that huge file as an mpg file and your cpu would have to do all the work.
Hope that helps you |

still working on this report for my oral examn is video capturing, there is no set literature of book or whatever. the teacher picked the subjects , stuff like touch screen , video capturing and more hardware related stuff like that, we never saw anything about those subjects in class thats just the hard part about it.
i still dont know much about video capturing, exactly because i never done it and i never had a book or anything about it. those websites you guys gave me explained bits and pieces but i never got the whole picture, it seems theres so much about this video capturing related stuff i dunno where to begin.
like all the file formats vcd and that stuff
the analog digital stuff i dont get that stuff
the insane amount of different hardware cards used, what the hell are all those, whats the difference between them :((
i can go on and on ive read about ulead software and adobe software, havent got those.
but probable biggest problem of it all, i havent got a video capturing card or digital camera or whatever, so i cant capture things (i think?) and so i cant learn by doing it, its looking so terrible hopeless that i'll ever learn how video capturing works atm :( |

just been to school, it seems the report aint good, teacher says its gotta be more about hardware related with vid capturing as its for the course hardware..
now i'm puzzpled what more i can write about the hardware:
i wrote about analog, digital , combi cards.
analog to digital convertor boxes and about vcd formats.
and a small bit about USB and FireWire.
what more hardware is there to vid capturing that i'm forgetting? |

You should write more on Fire Wire and how to actually capture, and about Time code on video camera's.. and all stuff about that. U Written anything about video camera's?? Video camera's are the source so u should spin some crap about them, and how they work etc etc....
