Why this tool is useful
Create a lighter preview or a smoother short WebM with a declared canvas capture rate you control.

Private Video Frame Rate Changer
Record a browser-decodable clip at a selected frame rate as WebM without uploading the source video.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
How it works
The output canvas captures transformed frames at the chosen rate while MediaRecorder writes a fresh local WebM timeline.
Practical example
Convert a short 30 fps browser-playable clip to a 12 fps preview and verify the selected output rate in the report.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
