Technically, packaging a 720p video into a 700MB MKV typically involves efficient video codecs (e.g., H.264/AVC or H.265/HEVC), a moderate bitrate to keep file size low while preserving acceptably sharp visuals, and possibly a single or dual audio track (Bangla stereo or compressed surround). Subtitles—either embedded or external—are commonly paired to reach diasporic audiences.
