iBooks Author movies not displaying properly
The two movies in my portrait IBA book play OK on an iPad when selected using thumbnails at the foot of the TOC, but when selected by other methods e.g. swiping from previous page, or selecting from the TOC list, the first frame appears briefly then vanishes, leaving a page that is blank apart from the page number. The full-screen movies (2x size at 2048x1536px) were made with Tumult Hype, made into .mov files with QuickTime screen recording, then resized to 1024x768 and converted to m4v using Subler. The book is synced from iTunes. Can anyone help please?
