What happens when converting TS to M4B?
The TS data is decoded inside your browser with WebAssembly and re-encoded to the M4B specification, so no file is ever uploaded to a server. M4B uses lossy compression: the file gets far lighter, but a small amount of fine detail is discarded in the process. TS supports animation while M4B does not, so only the first frame is kept. Audio is re-encoded with the M4B codec while keeping the original duration, so audio and video stay in sync.
