Document Summary

Video overview: what is video, capturing video, editing video, compression strategies, data rate, codecs, file formats, terminology. Conventional tv: digital each frame is a bitmapped graphic, stored as 0s and 1s. *assumption you took the footage: capture video download video from camcorder to computer, edit digital video using computer, digital video software, output video output to different file formats (back out to tape, the web, dvd) Information is sent as 0s and 1s: thus, no need to convert it because it is already converted. Digital video camcorders: most dv camcorders do a little big of compression right inside the camera, dv25 is the most common dv compression used (cid:271)(cid:455) toda(cid:455)"s (cid:272)a(cid:373)(cid:272)o(cid:396)de(cid:396)s (cid:894)it is a compression algorithm for video) Colour compression in the camera *: for still images rgb colour model is commonly used, for video, the model yuv (yiq) or ycbcr (model = colour space, y luminance (brightness, uv or (cbcr) chrominance (colour, ex.
