Multimedia missing from ePub

Tags: #video #cs5.5 #export #epub

I'm repurposing an INDD source to develop my first epub, and I'm running into a problem that is keeping me from making much progress.


I'd actually approached the layout with this effort in mind, threading the text throughout while anchoring other elements, and that all looks good so far. But one of the additions we hoped to make was to add video clips.


I excerpted a single page as a sample to see how all this was working, identify styles that wanted updating, etc. I also took the opportunity to replace a photo with one of these clips while anchoring it to an appropriate place in the thread.


Upon exporting to epub, however, while the other photos appear, the clip doesn't show up. Upon opening the epug in Sigil, it turns out that the movie IS exporting—landing in a "Misc" folder; it's just that any reference to it is being dropped in the XHTML. Validation through Sigil prompts this warning:


This resource is present in the OPF <manifest>, but it's not reachable (it's unused).


I cannot find anywhere to adjust settings specific to multimedia inclusion, nor am I doing any hand-coding that would generate, say, a misspelling or mistaken reference.


For the record, I'm running ID7.5.3 on Mac OS 10.6.8—and Sigil 0.5.3 as a result. Is this part of the equation? If so, I have even more cause for delight at the new rMBP heading my way...

    When I started tinkering with ePubs, I used Sigil as well. It took me some time to figure out it does things on its own -- some innocent, such as restructuring your HTML and linked files folders, some harmful, such as *silently* tidying up the HTML. That includes removing all HTML codes it does not recognize, such as the <video> tag you were expecting.


    Drop Sigil and use another ePub editor to inspect a brand new exported ePub. Then check if the issue persists.

    Um. TextWrangler? You'll need some tool to unpack and repack epub files as well; Google will help you with those. That's what I used.

    I was just at the Print and ePublishing Conference. Gabriel Powell recommended an inexpensive Mac app you can download from the Mac App Store. I think it was $3.99. Just drag and drop files on it to Zip and Unzip. And it can also do validation.


    It's called ePub Packager.

    Sigil has evolved quite a bit in the last versions. Now it's possible to disable auto cleaning/formatting (version 0.7+, preferences > clean source). You can also include audio and video through the interface, Sigil willt take care of the code part.
