Calculate a decision using explicit inputs. These tools run in your browser, do not upload media and explain the formulas and limits behind the result.
Plan file size and storage
- Video bitrate calculator — find an average video budget from a target file size
- File size estimator — combine average video and audio rates
- Recording storage calculator — allow for streams, copies and free capacity
- Audio file size calculator — PCM or compressed audio
Plan framing and timing
- Export time estimator — extrapolate a measured sample
- Aspect ratio calculator — reduce dimensions and derive a new height
- Resolution and crop calculator — centered crop or fit with padding
- Frame-rate duration converter — reinterpretation vs duration-preserving conversion
Use the output responsibly
Estimates depend on the values you enter. Average bitrate, container allowance and sample representativeness matter. Framing calculations give geometry; check the subject in the actual editor. No tool claims to predict visual quality, platform acceptance or hardware performance.
