Re: image sequence -> QuickTime movie

Hi,

Since a QuickTime reference file is just basically a text file that links to
images and sets a playback rate I was hoping that I could find a quick way
to create QT files for about 150 different sequences? Maybe use some
scripting? The data is so large (2k, 16bit @ 24fps) that using the QuickTime
7 Player is taking forever- is there a better way?

Are you asking about avoiding the use of Quicktime Player entirely, or just avoiding the use of Quicktime Player on a manual basis? Image sequence importing is trivial with Quicktime Player and AppleScript, but the same performance issues will apply, you just won't have to sit there and do it one at a time.


I'd imagine QT Player isn't taking so long to actually create the reference movie, but rather to open it afterwards (which is why the performance varies by the total amount of data, not by the number of frames). But regardless of how you do it, obviously at some point this data will need to be opened.

On easy way that should work fine is to simply generate SMIL files as your reference movies - basically create a SEQ, populate it with a bunch of IMGs of short duration. Then you can treat this file as a Quicktime .mov when you're ready to read/open it. Generating a SMIL is quite easy and can be nearly instant (just a little text processing).

For instance,

<seq>
    <img src="movie1/001.bmp" region="r1" dur="0.1" />
    <img src="movie1/002.bmp" region="r1" dur="0.1" />
    <img src="movie1/003.bmp" region="r1" dur="0.1" />
</seq>

Just a simple example, YMMV.
