In Camtasia 7; I was able to use a custom video output that allowed me to directly import the MP4 file from Camtasia into iBooks Author. However, in Camtasia 8, this format no longer works. Is it possible to have the output back to Camtasia 7? (The format was: MP4/Flv/SWF, Controller: No Controls, File format: MP4, Video Size: 800x600)

Hi Christopher,

I am trying to understand better of your question. In CS 8, you can still produce to MP4 which is the same as in 7 except from this production path in 8, FLV and SWF are removed. So if MP4 is the format you use in iBook Author, it should do the same thing for 8 and 7. Do you have more specific info on why MP4 from 8 is not allowed in iBook Author?

Thanks,

Kevin

I'm not quite sure why it would be accepted from 7 but not from 8. I tried it with and without hotspots too and it still gave issues.

I ran both MP4 files through MediaInfo to see any formatting differences; these are the only ones that I saw.

The file size for 8 is 807 kib vs 653 kib
The overall bit rate in 8 is 151 kbps versus the bit rate in 7 as 122 kbps
The format profile for 8 is Main@L3.1 and the format profile for 7 is High@L3.1
The Format settings, ReFrames for 8 is 3 frames, the format settings, reframes for 7 is 4 frames.
The 8 does not have format settings but 7 has format settings, GOP: m=1, N=50
The Bit rate for 8 is 149, while the bit rate for 7 is 118
The frame rate for 8 is 30.000 fps, the frame rate for 7 is 10.000 fps
The Bits/(Pixel*frame) for 8 is 0.010 while the .025 for 7.
The Stream Size is 797 KIB (99%) for 8 but 632 KiB (97%).

If necessary; I can upload both files to a dropbox account if you think you can see any other data that may be contributing.

My hunch is iBook Author probably only accepts certain profiles in MP4 production, so would you please try to produce your MP4 using High profile at level 3.1 and see if that helps? You can tweak this settings in "Custom production settings->MP4->Video Settings tab->H.264 profile and H.264 level"

Thanks,

Kevin

Unfortunately, that solution didn't work. I produced the video in both High and Main profiles without iBooks author accepting the file. Any other suggestions?

Sorry, it didn't work for you. We are now testing here in house, will get back to you once we figure it out.

Thanks,

Just a quick update on this, we have confirmed the issue and we are looking into it.

Hi Christopher,

I think I know what's happening with CS 8's MP4. iBook Author only supports M4V with H264 video codec (http://support.apple.com/kb/HT5065). In CS 7, we write a M4V flag in the MP4 file (though for other purpose), and this type of MP4 file (also uses H264 video codec) is recognized as a "M4V" and accepted by iBook Author. But in CS 8, we use a new version of MP4 authoring SDK and writing this flag is no long available (also not needed for the original purpose in 7), so this typ of MP4 is not accepted anymore in iBook. I tried a few non-CS-produced MP4 files (H264/AAC) from other sources, they all failed when importing to iBook.

Currently, what you can do is use CS 8 to produce M4V files which can be used in iBook just fine.

Hope this heps.

Is there any chance that the M4V file in CS8 can be updated to include the ipad screen size? I think currently it's limited to the ipod touch - iphone.

Additionally, do you have any experience or knowledge if using Hype for Mac will allow the M4V file to be imported into iBooks author using the Widget function? I dont like the idea of using another software program to solve this issue but if I could just import the HTML5 version and not have to create a two videos for training while also allowing interactive portions from CS8, that could be a great feature.

I am not allowed to talk about certain features in the coming releases, but that sounds a good idea to me. Also I have not used Hype for Mac before, so I can't comment on that, but it looks to me MP4 has become more and more popular, so maybe iBook will support native MP4 later and that would simplify your workflow?

Thanks,

Kevin
