I would take the videos and re-wash them to new files inside Adobe Media Encoder. I would save-as the digital images to new files, too. I would export the InDesign document to .idml and then re-open that. Then replace the files into the layout and re-export to EPUB.
More basically, tho, what version of InDesign are you using? 5.5, 6.0, and CC were not ready for prime-time. I recommend 2014 or 2015 in order to get relatively bug-free code.
Moving to InDesign EPUB forum.
Thanks Michael -
I've used the Apple 1280 x 720 preset for the videos in Media Encoder - so that shouldn't be the issue. Are there different presets that you recommend than that?
Presently, I'm using InDesign CC 2015. I saved as IDML, opened that file and re-published. The first video did not crash, but the second one and all after that one did.
I have replaced all graphics and video files and even hand-typed the content (I thought importing from Word was the problem - and that fixed a lot. It wouldn't even open before.)
Is there a good debugger that you would recommend?
This workflow is not good. I'm an expert user and I'm struggling - I'm supposed to be leading a team of InDesign novices to generate content with this application. :/
The issue, it seems, is when you put a video into a text frame. Videos that are not inside of text frames are not crashing the devices.
This is a bug that maybe ought be looked into? Or it should be published as a best practice *not* to use videos with text anchors.
Which means a different layout technique and more reliance on the Articles panel, right?
I wouldn't even bother placing videos into the document until it was 99% done. Use a placeholder frame.
That will speed up the process of testing the layout in ereaders. At the end you can just drop in the videos and get on with things.
In the mean time, if this is reproducible only in iBooks, report it to Apple. It's their app that's crashing. Also, try it in Readium for Chrome and Adobe Digital Editions to isolate the issue a bit further.
