Are iBooks Author 1.0 Files Incompatible with iBA 2.0?

Note: Since I first publishing this post, I took the leap and updated to iBA 2.0. (Of course, I had to because iTunes only accepts new books created in iBA 2.) I published three books in the new software and was also able to successfully open iBA 1.0 files in 2.0 and even copy widgets and other content from 1.0 to 2.0.

I still haven’t upgraded to iBooks Author 2.0, so I cannot verify any of these claims. But this information adds to my prior posts detailing issues with iBA 2.0.

First an excerpt (and image above) from What Apple Didn’t Say About Changes From iBooks Author Version 1 Series by Claxton Creative.

When we opened our .iba file made from the version 1.0 series (It was last opened on Aug. 23, 2012) in version 2.0 on Nov. 24, 2012, we immediately got a flag warning from the software saying that the image on page 156 was too large. Thumbing through the book also showed that iBooks Author 2.0 had messed up multiple widgets we’d laid out perfectly in version 1.0. They were compressed into a tiny size and were sitting at the left sides of pages. Several of them we’d laid out to encompass an entire page. Version 2.0 messed all that up and required us to repaginate several places in the book.

… A dialogue box appeared and said an image that worked fine up until Oct. 23, 2012, was no longer any good in our book for iPad.

… Things got even wonkier after that. There were multiple widgets in the book that got totally screwed up by iBooks Author version 2.0. …. some of them got zapped in size and then moved to the top left portion of a page, completely affecting the pagination within a chapter. More 

Next some chatter from the Apple Support Community boards:

MrBlobby1970 begins a discussion about problems with iBA 2.0 by writing ….

Upgraded to iBooks Author 2.0 and it has rendered my book file unusable. Is there a way to download iBooks Author 1.0/1.1 after you have upgraded to 2.0?

I have tried the book file with a friend’s iBooks Author 1.1 and it still works, so it’s something with 2.0 that just doesn’t like my files. More
 

In another Apple Support discussion Patrick-betterthanworksheets writes

Updated iBooks Author to 2.0 but can’t seem to load the iBook I was perviously working on (says cannot load document). Still loads fine on my other Mac using the pervious version of iBooks. Happen to anyone else or is this just a glitch with my file? Not a huge deal since I can use the pervious version to finish it off but just wondering. More

OK readers, its your turn – Is anyone else having compatibilty issues with iBA 2.0 and 1.0?

Why I Haven’t Upgraded to iBooks Author 2.0

Note: Since I first publishing this post, I took the leap and updated to iBA 2.0. (Of course, I had to because iTunes only accepts new books created in iBA 2.) I published three books in the new software and was also able to successfully open iBA 1.0 files in 2.0 and even copy widgets and other content from 1.0 to 2.0.

Over the last few months I’ve been blogging regularly about my iBooks Author (iBA) learning curve and the production of my first iBook. Along the way I have come to rely on the advice of Dr. Frank Lowney Projects Coordinator, Digital Innovation Group @ Georgia College.

BTW – Frank published The Coming ePublishing Revolution in Higher Education on iTunes. It’s an insightful guide to etextbook revolution – winners, losers, and the factors that will determine the outcome. (67 pages, 20 graphics, 28 media files, 25 video files and 5 interactive widgets.) A bargain at only $0.99!

Frank’s been most generous with his time and advice on technical aspects of formatting videos for use in iBooks Author. Recently he contacted me about some troubling features in the new iBA 2.0 which I summarized in a post – Read This Before You Upgrade to iBooks Author 2.0. As a result of that post, I was contacted by Jay Welshofer (Apple’s Senior Product Manager for iBooks Author and Keynote) who has been working with Frank to better understand the video encoding issues with iBA 2.0.

Rather than expose my veneer of understanding of video technology, let me quote some of my correspondence with Frank so that others can benefit.

I begin with three questions I posed to Frank about iBA 2.0 video optimizer ~ Frank’s replies:
1. Does it do an acceptable job on quality? (a bit of a change from your earlier appraisal)
~ Yes, the quality is quite good if the source is good. I haven’t yet done a lot of testing with lower quality source but that’s on the todo list.

2. Does it increase file size ?
~ Absolutely. The bloat is up to three times the size of what Handbrake outputs with no appreciable difference in video quality.

3. Does it wipe out subtitle tracks
~ Every time. Alternate audio tracks and chapter tracks too. Of course, chapter tracks are not relevant to iOS video except in the Videos.app which has an interface for chapters that is separate from playback. Older versions of quicktime presented chapters as a drop down menu in the controller which lends itself to all kinds of neat pedagogical uses.

To reinforce his point Frank ran a test video conversion comparing iBA 2.0 and Handbrake and supplied a video sample of each. He writes:

Dear Peter and Jay,
I have been unable to reliably replicate my initial report where video quality was significantly lessened by the IBA media optimizer. Actually, this optimizer does a pretty good job of maintaining video quality no matter what you throw at it.

However, there is still the problem of file size bloat that started this whole line of investigation back in the IBA v1 days. As you’ll recall, IBA would reject many videos and recommend re-encoding in QuickTime Player and that would create files 2-3 times larger. This was a concern to many IBA users due to the 2 GB limit on iBooks in the iBookstore.

Back then, the workaround was to tweak the output of more efficient systems such as Handbrake such that IBA wouldn’t reject them. Now, with IBA v2, the use of QuickTime is no longer optional and the file size bloat issue is with us again. The new workaround is to use the video replacement surgery tactic that I described earlier. It’s a bit more daunting than the earlier workaround because you could break the whole iBook just by getting the name of one video file wrong, a typo for example.

As promised, I’ve constructed a hardball case documenting this issue as follows. An executive summary in the form of a screencast comparing the iBooks Author encode to the Handbrake encode will have more general interest. Here it is:

The source file came from a “pro” level HD DV camera and was provided to us as a ~16 GB DVCPRO HD file at 720p. As you can see from the video, iBooks Author encoded this as a 1.5 GB file (causing a warning about the 2 GB limit) whereas Handbrake 0.98 (Apple TV 3 preset) produced a 532 MB file, a third of what IBA produced. Also evident in the video should be the fact that there is no discernible difference in size or quality.

BTW, I used QuickTime Player 7.6 for this demo because it can play two or more videos sychronously allowing much better qualitative analysis. QuickTime X Player cannot do this.

Read This Before You Upgrade to iBooks Author 2.0

Note: Since I first publishing this post, I took the leap and updated to iBA 2.0. (Of course, I had to because iTunes only accepts new books created in iBA 2.) I published three books in the new software and was also able to successfully open iBA 1.0 files in 2.0 and even copy widgets and other content from 1.0 to 2.0.

I recently published my first iBook Why We Fight: WWII and the Art of Public Persuasion.
It features over a dozen historic propaganda videos. I used iBooks Author 1.0 (iBA) to create the iBook, and with lots of advice from experts, I managed to create good quality videos of manageable file size.

Before I upgraded to iBA 2.0, I thought I’d do some research.
I’m glad I did, because it appears that the new iBA 2.0 “Media Optimization” feature has mixed reviews in video management. That early analysis comes from Dr. Frank Lowney, Projects Coordinator, Digital Innovation Group @ Georgia College. Frank spent many hours online answering my questions about importing videos into iBA 1.0 and I owe him a big thanks.

Here’s some of what Frank wrote about iBA 2.0 in his comment to a recent MacWorld review.

IBAv1 was terribly finicky about video. It rejected videos that played perfectly well in the Videos.app on iPad. The current optimization routine is an apparently a well intentioned correction of that finickiness.

… If you are writing a textbook or any kind of book containing video that requires providing soft subtitle tracks to address accessibility and other important goals or alternate audio tracks to reach a wider, multi-lingual audience, be aware that this optimizer will strip out those valuable assets without notice. Of concern to a wider group of authors is the violence done to certain videos by this “optimization” routine. Although it works quickly and does a reasonably good job on video that is already close to optimal, it wreaks havoc on video that is not. 

…The worst part is that you cannot revert to the old regime.

For more a detailed analysis see this thread in the Apple Support Communities Preventing iBooks Author Media Optimization where Frank comments: 

The optimization routine in iBooks Author 2.0 is well intentioned but the execution of those intentions is quite poor. In addition to bloating the size of your videos and, hence, your iBook, it can also degrade visual quality in dramatic fashion.
… With iBooks Author 1.x, I had figured out how to create very efficient and highly capable video that IBA will accept. This “feature” throws me and a lot of other capable people into a ditch.

I asked Frank if I can use his comments and he agreed, while noting he hasn’t had time “to do full range of tests and documentation that I prefer to do.” But his early reviews suggest that I’ll wait to upgrade. Who needs bloated files, lost subtitled tracks and poor video quality?

Nov 9 Update from Frank Lowney:

Peter,

As you’ll recall, the caveat was that my findings re video in IBA 2 were preliminary and, therefore, subject to revision as I conduct more rigorous tests. I may well have to eat some of those earlier words. I’m still nowhere near a definitive opinion but I did manage to do a comparison between videos submitted to IBA and what they looked like after the “optimizer” got through with them.

The way to do that is to change the suffix of an *.ibooks file to zip and then use something like the free Stuffit Expander to expand the archive and reveal its folder structure and enable examining the contents. Video files are all in /OPS/assets/media/.

So I created five new videos for my iBook, loaded them into IBA, let the optimizer have at them and then compared the file size of the originals with what I found inside the *.ibooks file. I was surprised and pleased to find that four out of five were pretty much the same as the originals in both file size and quality. The odd one was 7.6 MB in the original and 8.2 MB in the *.ibooks file which is not huge. IBA apparently jacked up the data rate a little.

Of course this was a “soft ball” since the source came out of the recently released ScreenFlow 4 using a custom settings designed to be optimal for iPad (a multi-pass encode at 1024×768 using H.264 in a MOV container). Except for changing the container from .mov to .m4v, everything was the same in the *.ibooks file: bit-rate, frame rate, height, width, etc. So if you give IBA something that it expects and respects, it does no harm.

I’ll start throwing hard balls in the coming days and we’ll see what happens.

I’m sticking to what I said about soft subtitle tracks and alternate audio tracks. These are incredibly important in an educational environment in terms of Section 508 and 504 compliance. As well, being able to offer multi-lingual access is critical to the success of on-line learning. What IBA’s “optimizer” does to them is indefensible. There seems to be a contingent at Apple who think that Closed Captions, a throwback to analog TV broadcasting, is sufficient but they are dead wrong. It relies on a binary format that can only be created by expensive and difficult to use software (go ahead and price MacCaptioner) as contrasted with SRT, ASS, etc. that anyone can create with a simple text editor.

So, for people who aren’t concerned about subtitles and alternate audio tracks, the upgrade to IBA 2.0 appears to me to be a good move. The new widgets are awesome, especially the scrolling sidebar which looks a lot like what I described in an enhancement request that I submitted. The only people for whom this is a show stopper are the folks that are prepping video for iBooks and working for institutions and corporations that simply must address these accessibility issues. Indies like you and I can ignore these issues for the time being. The stuff I do at work is another story altogether.

More later and thanks for being a great sounding board.

Textbooks Are Dead – Here’s 3 Reasons to Write Your Own

For years progressive educators have known the textbook was dead. Apple’s latest iPad Mini / iBooks Author event (October 23, 2012) suggests we are closing in on the tipping point that should hasten its demise.

I’ll let others critique the viability of the iPad as a textbook replacement in this era of shrinking budgets. Instead I’ll focus on how teaming iBooks Author (iBA) with the iPad can turn students from passive consumers of information, into active researchers, thinkers, designers and writers.

Since it’s release this spring, I’ve been working with iBA and networking with other educators doing the same. I’ve seen great examples of student-produced work such as this iBook by 5th graders.
I just published my first multi-touch iBook, Why We Fight: WWII and the Art of Public Persuasion which gives students a chance to work with historic films and poster art to critically evaluate the US government’s public relations effort during the war. I’ve already blogged about my reactions to using iBA, but let me use this post to offer three arguments for using iBA with students.

Crowdsourced Production
 iBA (a free program) requires a Mac running OS X 10.7.2 or later, but that doesn’t mean that every student needs a Mac to contribute to the iBook project. All the classroom needs is access to one computer running iBA to create an iBook. (Use somebodies new Mac Mini?)

iBA accepts text from Microsoft Word and other text editors. Teams of student writers can do research and writing on a variety of computers (and devices) and send finished copy to the iBA production team. Images, audio and video files collected by researchers can be added to the eBook project with a simple drag and drop. If students have access to multiple Macs running iBA, it’s easy to consolidate iBA projects by copy / pasting chapters (or sections of chapters). Research, writing, and design can even be sequenced into a “flipped classroom” production model.

Broadcasting Your iBook
Terms of use for iBA require that iBA-created iBook that are offered for sale can only be sold through the iBookstore. But there’s no restriction on “free” iBA-created iBooks – circulate them any way you want.

While the iBookstore does provide accounts for producers of “free” iBooks, there’s a simpler way to distribute an iBook. Connect an iPad to the computer running iBA, click Preview, and the iBook is pushed to the attached iPad. Do the same on as many iPads as you choose. It’s also easy to export the finished iBooks file from the iBA program to an external drive or network and distribute the iBook to multiple iPads.

The ease of distribution means students can communicate with a broader, and more authentic audience than just their teacher and class peers. They can even bring their iBooks files home on thumb drives to be shared with families and friends that have iPads.

Design Thinking Meet CCSS Skills
Researching, writing, and designing an iBook provides an opportunity for students to hone a wide range of skills. Common Core State Standards require a host of literacy, critical thinking and writing skills that are essential to production. Project based learning (PBL) engages students with the opportunity to think like professionals while solving real-world problems. While the iBook qualifies as a project goal, don’t forget that the subject of the iBook could also give students a platform to tackle community-based issues.

Collaborating on an iBook draws from a wide range of creative skills – creating audio clips, producing illustrations, shooting and editing video. Because a variety of media can be included in an iBook, there are numerous opportunities for students of all ability levels and language proficiencies to be active contributors.

Digital technologies have put students in charge of the information they access, store, analyze and share. Most importantly the digital era has given them an expectation of informational choice. Creating an iBook harnesses all those motivational factors into an engaging learning experience. When students get to collaborate and work as adult professional do, we relinquish responsibility for learning to the student and provide them a valuable opportunity to reflect on both their process and product. That’s the foundation for a lifetime of learning.

Do Not Use iBooks Author to Author an iBook

After loads of research and design work, this week I eagerly uploaded my interactive, multi-touch book -“Why We Fight: WWII and the Art of Public Persuasion” for approval at the iBookstore.

A day after my upload, I received an error ticket for using the term “iBook” within my work.

Use of Apple Inc. Copyrighted Terms (Description) Books must not:
Use the phrase “iBook” to describe the book. iBooks is the trademark for Apple’s book reading software, and iBooks Author is the trademark for its electronic book creation software. Books created with Apple’s iBooks Author software and/or sold on the iBookstore should be described as a book, ebook, electronic book or interactive book, but not an “”iBook.”

Perhaps I’ll rewrite into something like “Here’s how to navigate this book on your Pad.”
