Here’s a tool I have made that I use to create an instant sheet of thumbnails from a movie. I use it to analyze animations that I have digitised from my own video collection.

It works in principle but there are a number of issues I’ll go into in a moment. It is an early version of an idea that could produce instant time-lines, retrospective after-the-fact storyboards, onion skinning and other video frame manipulations. I use it to visualize the flow and movement of time-based imagery and to produce illustrations for lectures. It is the kind of process that makes Quartz Composer a pleasure to use. To produce such a layout in Photoshop would take a good deal of preparation and layout work. I love the grid layout and the visual effects produced by this patch – as images in their own right.
You set the path to a quicktime movie.
Make some basic choices about number of frames per row, number of rows (you need to enable / disable each row as needed)
Set the time interval / frame shift to jump on each row.

Here are some of the important issues that need to be improved:
The patch runs slowly. I am sure you could do a similar thing programmatically with QTKit that would be much faster in the generation of the rows / thumbnails. I may even have a bug / design flaw where each row gets iterated more than once.
It is always a design goal for me to have no manual tweaking necessary, for a composition to do it’s work with the minimum amount of set-up. This patch needs more work in this regard.
It seems some codecs (I forget which from my tests – I mentioned it on the qc-dev list) produce unexpected results. i.e. only two different thumbnails are generated and they then alternate across the sequence. Some sizing / aspect ratio issues of the thumbnails when the viewer is resized
I have fixed this issue on other similar patches I have made – but have yet to implement the fix here. This patch would benefit a rigorous going over. I’d love to hear from anyone who finds it useful.

i published an essay (jan 2001) on world puppetry and performer training. research was drawn from research and participation at the henson international puppetry festival, new york (2000) and a symposium at the victoria & albert theatre museum, london (2000).

“It is logical to assert that voice is a primary tool for the puppeteer when bestowing the impression of life on dead things”
“Giving voice to objects, along with movement, is a principle tool of the animator when intimating the â€˜presenceâ€™ of a soul.”
“As soon as a puppet speaks, it is cultured, it has a past – it is not only living, it has lived”
“No matter how much some performers, scholars and trainers dislike puppets speaking, puppets and objects will be given and will find their voices.”
