Some services deliver high-quality video and audio as separate streams. A media processing tool can combine compatible streams into an MP4 container.
Does MP4 guarantee the highest resolution?
No. The resulting file depends on the available source formats, accessibility, codec support and the processing limits of the service.
When processing can fail
Protected material, private URLs, expired links, unsupported streams, geographic restrictions and platform changes may prevent preparation.
