Video Size Calculator Pro

Plan video sizes in seconds. Pick resolution, FPS, codec & audio, batch clips, or work backward from a target size.

Video Size Calculator Pro helps filmmakers, editors, and creators predict video file sizes before recording or export. Choose resolution, frame rate, codec, audio format, and duration to get instant, accurate estimates — then balance quality vs storage with confidence. Works offline, no accounts or tracking.

Core tools • Size Calculator: 20+ resolution presets (720p → 8K/8K DCI), 15+ FPS (23.976 → high-speed), 25+ codec families (ProRes, H.264/H.265/HEVC, DNxHD/HR, AV1, VP9, MPEG-2, ProRes RAW), audio presets, overhead margin, binary/decimal storage toggle. • Batch Calculator: Add multiple clips with their own settings, see per-clip + total size, and export a summary for planning. • Reverse Calculator: Start from a target file size + duration; get suggestions and side-by-side comparisons to hit your goal.
