sharing 300x225 Sharing knowledgeI thought I’d dedicate today’s post to sharing a few of the very nice ScreenFlow tips and tutorials that we’ve seen lately from some of our fabulous users. These are in no particular order, and if I’ve missed any recent ones, please let me know in the comments below.

Thank you to all of you who are willing to share your time and expertise to help others!

    I’m looking for ways and means to record AppleTV output. For other environments, I’ve used simulators (iPhone, Newton, Apple II, Atari, etc.). Once the simulator is functioning and on my screen, ScreenFlow will capture it.

    There is an open source project (BackRow Dev Kit) but that only supports version 1.1 of the AppleTV and doesn’t appear to have been worked on since 2008.

    So I’m looking for ideas on other ways to accomplish this,

    Frank,
    I don’t know off the top of my head. I’ll ask around here to see if anyone knows of anything. Anyone else have any suggestions for Frank?

    RE: How to use YouTube annotations in your ScreenFlows by Alex Lee

    This is very interesting and useful. YouTube also offers subtitling with the very simple and easy to create .SRT format.

    However, this media isn’t portable so you are tethered to YouTube for better or for worse. This can be a problem if, like me, you have to make video available in more varied and flexible ways and sometimes confine access to a specific class of students.

    It is possible to do some of this using Apple’s .m4v and .mov containers such that your media assets are more fully portable. Multiple soft subtitle tracks and multiple alternate audio tracks can be added using an open source app called “Subler.” Screenflow, will add a chapter track based upon markers. Here are a number of screencasts illustrating how these elements are invoked and how they play back in several different environments:

    Chapter Track: http://hercules.gcsu.edu/~flowney/research/MPEG-4/chapters/
    Soft Subtitles and Alternate Audio Tracks: http://hercules.gcsu.edu/~flowney/research/MPEG-4/subtitles/

    QuickTime used to support what were called “wired sprites” such that, with applications like LiveStage Pro, one could install all sorts of interactivity into the video file. I would submit a ScreenFlow feature request to use some of this stuff but it appears that Apple is no longer supporting it and has embarked upon a different path.

    Flash and Silverlight enable this kind of interactivity but media based upon these architectures don’t currently play everywhere I need to be (iPhone, AppleTV, etc.). Apple seems to be taking the open source route where interactive controllers, for example, are external to the media and built using Javascript, CSS and SVG. Then, too, the emerging HTML 5 standard, especially the new tag do not currently expose chapter, subtitle and alternate audio tracks, let alone provide this kind of interactivity.

    Perhaps Telestream is working on a new desktop application that generates the increasingly complex code with which to place video in any standard web environment, code that provides this kind of interactivity and access to non-A/V tracks. Apple does a little bit of this with the “Save for web” feature in QuickTime X (free) and, previously, QuickTime 7 Pro ($30). This is very basic compared to what is needed.

    OK, here’s another Quixotic quest. Doing overlays in ScreenFlow is very easy. They can even be animated to a degree. Although I cam make a fixed length arrow move across a given space, I cannot make an arrow get longer, curve and change direction.

    In TV technology, this is called gen-lock video. It’s what they use to review sports events drawing Xs, Os and arrows over a video clip.

    Can anyone think of a way to do this in ScreebFlow 2 or is this an enhancement request?
