Calculation Logic

MOV is a multimedia container format developed by Apple, whereas MP4 is a widely compatible video container format. This tool utilizes a WebAssembly binary of FFmpeg. For compatible codecs, the engine extracts the video/audio streams and packages them directly into an MP4 container, preserving 100% quality.

FAQ

Is there any loss in video quality?

None. Because the raw file data is copied directly without re-compression, this is a mathematically lossless change.
