This paper analyzes the technical characteristics and encoding efficiency of a high-definition video file. A 14.88 MB file at 720p resolution represents a highly compressed state, typically indicating a short duration (less than 1 minute) or the use of advanced codecs like H.265 (HEVC) or AV1 to maintain visual fidelity at a low bitrate. Resolution: 1280 × 720 pixels (Standard HD).
MPEG-4 Part 14 (.mp4), chosen for its universal compatibility and streaming performance. File Size: 14.88 MB.
Calculation Reference: At 3 Mbps, 1 minute of 720p video typically requires ~22.5 MB.
