What happens when converting MOV to OPUS?
The MOV data is decoded inside your browser with WebAssembly and re-encoded to the OPUS specification, so no file is ever uploaded to a server. OPUS uses lossy compression: the file gets far lighter, but a small amount of fine detail is discarded in the process. MOV supports animation while OPUS does not, so only the first frame is kept. Audio is re-encoded with the OPUS codec while keeping the original duration, so audio and video stay in sync.
