Yes, BookBaby can create Fixed Layout eBooks for Apple Books and Amazon that include video and audio.
Audio files must be provided in MP3 format.
Video files must be provided in MP4 format.
Please note that we can not create "readalong" books or "soundtrack" books, as there is no way to ensure the audio clip will continue to play once the page is turned.
Another option for sharing video and audio with your readers is to simply link to the audio or video file on an external video or audio site, like YouTube.
