Yes. Both are retimed by the same factor in one operation, so they cannot drift apart — which is the usual failure when speed is changed by editing the two streams separately.

No. Change MP3 Speed is free without an account and adds no audio watermark or spoken tag to the output. Your upload is deleted from the workers shortly after the job completes.

Video is the case where extra round trips hurt most — the files are large and every upload costs real minutes. Running Change MP3 Speed on the same pipeline as the conversions means one upload covers the whole job instead of one upload per tool.
