qt_tools is a set of commandline tools for Mac that manipulate quicktime movies. One of the tools is qt_proofsheet:
QT_PROOFSHEET will take a QuickTime movie and render it out as individual frames in a grid. By default, it takes about 100 frames of your movie and fits it onto an 8.5 x 11 document, with timecode imprints.
By using different parameters you can make a strip of stills from a quicktime movie the one I am using here is 576 x 8208 pixels.
This is then animated with css. The qt-proofsheet adds the time stamp, you can minimise them but I found them useful is creating the animation.
For those interested, probably only a few, here is the code
The stills were grabbed from ‘Perchance to Dream’ an episode of the twilight zone.
I am afraid I am a bit sort of time so this post is a bit lacking in information, but this technique is an interesting take on the animated gif. The quality is fairly good and the file is 654kb.
