Calculating the File Size of an Uncompressed Digital Video: - Raw video data size = frame size (width X height) * frame rate (fps) * color depth (in bytes) * time (in seconds). 8 bits = 1 byte 1 kilo = 1,024 (from byte to bits) 1 mega = 1,048,576 (bite to byte) 1 giga =  1,073,941,824 (bits to bytes)  -for Audio: 8-bit mono Seconds x kHz = Size 16-bit mono (Seconds x kHz) x 2 = Size 8-bit stereo (Seconds x kHz) x 2 = Size 16-bit stereo ([Seconds x kHz] x 2) x 2 = Size 16-bit 5.1 ([Seconds x kHz] x2) x 6 = Size Factors to consider when selecting graphics to be used in a multimedia project: a) Purpose: – Avoid using images for “filler” or when they have little in common with the overall message or purpose

– 525 LINES/60HZ -USED PRIMARILY IN NORTH AMERICA, TAIWAN, SOUTH KOREA, JAPAN. – 30 FPS PAL (PHASE ALTERNATE LINE) – 625 LINES/50HZ – USED IN EUROPE, ASIA, AND SOUTHERN AFRICA. – 25 FPS SECAM (SYSTEME ELECTRONIQUE COULEUR AVEC MEMOIRE) – 625 LINES/50HZ USED PRIMARILY IN FRANCE, PARTS OF MIDDLE EAST, AND RUSSIA. – 25 FPS. by multiplying the frame rate by 2 you get frame rate per sec. PAL and NTSC uses 4:3 ratio. Analog signals uses wave length while Digital uses Binary. frame ratio for motion pictures (cinema) 24fps.
