Apple provides some documentation that describes how to get video into iBooks (http://support.apple.com/kb/HT5065) -- but this often massively increases the size of the files (4X in some cases) due to changes in the data rate of the resulting m4v file.
Are there any other tools that can do this conversion while providing additional control/flexibility of data rate / output dimensions?
I've tried handbrake, but can't find any settings / presets that iBooks will consume.
I've been trying to figure this out for days. I think I have a solution.
MPEG StreamClip (link) can export M4V files with more flexibility than QuickTime player. MPEG StreamClip is free (and awesome).
To make an M4V for iBooks author, start with your original video file. Try to use the raw output from your video editing software. The more times you transcode your video, the lower the quality of your final output.
This process makes M4V files that drop into the iBooks Author media widget just fine.
You can experiment with data rates to balance video quality with file size.
Hope this helps,
This actually works--except for one small problem: NO SOUND! The video DOES load into iBooks Author, but plays with no sound.
It's not your settings, but rather a glitch somewhere in the way Streamclip and QT work. Streamclip just doesn't seem to be getting or even recognizing the audio portion at all. When I play the m4v from Streamclip in QT, there is no audio info in the Inspector.
I tried playing the video on my iPad and it plays... silently.
On the desktop, it plays... silently.
There is a lot of chatter about this on the web but no solution. Most common suggestion is to install pervian. Did that. Silence!
Nothing's ever easy!
I've spent the day on this. I could not find a combination of settings in Streamclip that would result in SOUND! It just refuses to recognize the audio track in the .mov file.
I decided to try other video converters from the Mac App store. Video Converter (Leawo) would not export an .m4v regardless of the settings. Only mp4, which iBooks Author spits out.
Miro was no help.
iVi came through, with reservations. I was able to convert from .mov to .m4v (using Apple TV settings) and iBooks Author accepted the video. The quality is still not as good as what Handbrake exports, even though the file size is larger. But it's a start.
Maybe the folks at Handbrake will figure this out and issue a fix? Or the folks at Streamclip?
In the meantime, iVi works.
The answer to this is to use Apple Compressor. I'm using version 3.5.3, but I'm sure it's similar with other versions.
Once you've added your video, the file format should be "H.264 for Apple Devices." Then, the device should be "iPad/iPhone 4" and the Aspect Ratio is "16:9 (1280x720). I'm using a bit rate of 3000 Kbps and 128 Kbps for audio. You can of course modify these settings if you have different quality or file size requirements.
Hope this helps.
That's one of those suggestions that just seems too easy to work.
But, before plunking down $50 for Compressor, why not give it a try?
I thought I would get it over with quickly by changing the file extension on an mp4 that was decent quality and file size. For sure, I thought, it won't even play.
Well, it did play just fine.
But iBooks Author wouldn't accept it.
Maybe it makes a difference what software creates the file in the first place.
I'll try Compressor later today.
Success! Compressor 4 transcoded a .mov created in and exported from Final Cut Express (using Quicktime Conversion). The original video file is 448 MB. The exported m4v from Compressor (settings below) is arpproximately 26 MB. This is only about 30% larger than the m4v exported from Handbrake. But the Compressor m4v is 1280 x 720 and a faster bitrate than the Handbrake m4v, which is 1024 x 576. It looks --and SOUNDS--really nice.
And... iBooks Author welcomes it with open arms!
For me, that was $49.99 well-spent!
Here are the settings. This is a first try. I'll play around with them, but this works great! Good luck to all!
