Video Size Calculator Pro
Estimate video file sizes fast
Calculate precise video file sizes based on resolution, frame rate, codec, and audio settings, with 25+ codec support.

Size estimate
Estimate video storage before export.
Resolution, frame rate, codec, and duration inputs stay close to the estimated file size.

Reverse planning
Work backward from a storage target.
Reverse calculations help choose settings when a project needs to fit a specific size.

Batch planning
Plan several exports with the same assumptions.
Batch tools make repeated video size estimates easier to compare.

Export details
Presets and advanced settings keep estimates realistic.
Codec, frame rate, and audio options keep the storage estimate tied to the real export.
