Macromedia MX: Animation: RAM vs Disk streaming, LingoMaster, MediaMacros + Others

Hi folks,

I quote a comment to LingoMaster from my first question:

You will be able to distribute a Projector version of the final product.

Your animation based on still image sequences might be limited by available ram. If near full screen images sizes don't expect video frame rates.

The simplest most reliable approach may be to store the user edit session in a text file using fileIO xtra, as a sort of edit decision list, external images would be reimported each time the edit file is re-read.  The free Sharp image export xtra might be one way to capture free drawn caption notes for later playback, recording the mouse notion during draw operations is a possibility too.

This roundabout save to text file scheme is an alternative to the Lingo saveMovie function which doesn't seem to be that reliable under a projector.

There's an expensive 3rd party quicktime xtra available thhat can generate a movie file frame by frame.  Once output by your 'tool' the quicktime videos could be played at video frame rates, streamed from disk with no ram limited length

May I kindly ask you how may I implement my program so that images can be streamed from a disk (Hard Disk, CD, ...etc) rather than the RAM memory?
Which is more reliable: the first approach (FileIO Xtra) or the second (QTMovie Xtra)? Which is easier and more headache-free to deal with?

Can I find a ready-made code for streaming/reading images from hard disk to my Macromedia animation. If not can you help me out please as my knowledge and experience in Macromedia and Lingo is very primitive and shallow. Plus, I'll have to demonstrate something to my EEE professor by Friday this week.

Thank you very much in advance.

Best regards.

    Directlr doesn't really stream from disk, only from the web to local hard drive cache. All in all your goal sound too advanced for a school project.

    Export to quicktime can in some situations provide more reliable reproducability of long animations on slow systems.

    Director background preload option can be used to optimise playback from CD-ROM, it will load individual members during free time between other processes. IT's not quite streaming, as I recall all other actions are on hold as each individual member is loaded.  
     A shockwave compresse director file with internal bitmaps compressed to some 1/50 size can play from a CD more quickly.

    PLaing a lot of images, one after another is always going to be slower.  The QT approach will get better playback.
