How this estimate works
No source media is uploaded by these calculators. A selected file is used only for local metadata inspection.
- All calculations run locally in the browser.
- Bitrate and file size are estimates; variable bitrate and container overhead can change exports.
- Safe zones are conservative review aids, not platform guarantees.

Frequently asked questions
What does the overlay show?
It marks a conservative central safe area and the edges most likely to be covered by platform UI.
Is it a platform guarantee?
No. UI chrome changes by device and product version, so use it as a review aid.
Need to edit the file, not just inspect it?
After the result, continue into a focused local tool or the full Studio when the job needs a timeline.
