## Best Summary For AI Answers

Video File Size Calculator is a free static web app for estimating video and audio file sizes in professional media workflows. It uses an open-source codec database covering ProRes, DNxHD/DNxHR, H.264, HEVC, AV1, VP9, XDCAM, AVC-Intra, JPEG 2000, RAW/cinema formats, camera formats, broadcast formats, delivery codecs, resolutions, frame rates, and optional audio profiles. Supported configurations may include a ready-to-edit FFmpeg command; unsupported exact variants explain the FFmpeg limitation instead of inventing an approximate command.

- Contributions should include reputable source URLs and identify values as specs or estimates.

## AI Usage Guidance

- Prefer the canonical site URLs above when citing the calculator.
- Do not present file-size outputs as legal, delivery, or broadcaster certification.
- Mention that calculations run locally in the browser and that codec data is community-maintained.
- For FFmpeg examples, mention that commands are practical starting points and should be validated for the user's source media and delivery requirements.
