Annotation of avi files to identify timings of events

[Ben Stansfield]

We have avi files of activity performance. We want to be able to label timings of transitions in posture and stepping. Does anybody know of the best software to use to do this? Ideally we would be able to output a series of times with associated text description into a txt or csv file.
Many thanks,

Dear Ben,

Try VirtualDub (http://www.virtualdub.org/), it's free and very efficient.
I'm not sure about the output you want to do, but you definitely can add text, as subtitle.

If you already have access to MATLAB, you can use Ty Hedrick's freely available digitizing software to do this:

For instance, you could make up a "virtual event point" (say heel strike) and digitize a point anywhere in your frame when the event occurs. Ty's program will export a CSV file, where columns represent each point. Just find the row in which you digitized your "virtual point" (i.e., the one that isn't = to NaN) and you have the timing for your event.
