Why this tool is useful
Build a bounded repeating visual for demonstrations, silent displays or social previews without a server-side rendering task.
Local File Tools · runs locally
Private Video Loop Maker
Repeat a short browser-decodable clip two or three times into one WebM file 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 browser replays the local video on canvas for the chosen number of complete passes and records one continuous WebM timeline.
Practical example
Repeat a four-second browser-playable clip three times and verify the expected twelve-second output before saving it.
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.
