Which format is used for a sequence of frames encoded as a video stream?

• A. .GIF
• B. .MPEG
• C. .BMP
• D. .PICT

Answer: (B)

Video sequences rely on a format that supports efficient compression across consecutive frames. MPEG is designed for this purpose, using temporal redundancy between frames to reduce data with interframe coding (I-frames, P-frames, B-frames) and organizing video into groups of pictures. This makes it ideal for encoding a sequence of frames as a continuous video stream, enabling bandwidth-friendly playback and streaming.

GIF stores simple animations with a limited color palette and does not use the same frame-to-frame compression as video streams, so it’s not suited for general video encoding. BMP is a still image format and is uncompressed, not intended for sequences or streaming. PICT is an older Macintosh image format for still pictures, not a video format.
