Why this is different

Remux, not re-encode

Compatible streams are copied directly. That keeps the original quality and skips the CPU-heavy step.

Batch-ready

Drop one file or a whole folder. The workflow stays the same and the original files are untouched.

Made for AV1 WebM

Built for modern WebM files that should become MP4 without turning into a slow render job.
