How It Works
Video Size Calculator Pro makes professional video planning effortless. Start with the Calculator, where you can select from 20+ resolution presets (HD to 8K DCI), 15+ frame rates (23.976–120 fps), 25+ professional codecs (ProRes, H.264/H.265, RED RAW, Blackmagic RAW), and 15+ audio presets. Enter your clip duration and instantly see file size estimates with full breakdowns for video, audio, and overhead.
Need to handle complex projects? Use the Batch Calculator to add multiple clips with individual settings. Get per-clip and total storage requirements in one view, then export the data for planning.
If you’re working backward from a target file size, the Reverse Calculator suggests the optimal resolution, codec, and audio combination. You can even compare two different configurations side by side to balance quality and storage.
Whether you’re preparing for a film shoot, estimating YouTube uploads, or archiving in RAW formats, Video Size Calculator Pro gives you confidence and accuracy every time.
