finding types of events in movies - suggestion #349

Open roian opened 3 years ago

1) It would be nice to be able to easily change playback speed in the GUI for when you are browsing through a movie looking for something in particular to label or check. I'm thinking of something like a gas pedal.

2) Alternatively/additionally, it would be nice to be able to say "Calculate all the times the centroids of the these two targets was less than X" or "Calculate all the frames where the current target velocity was greater than Y", and then navigate between the identified events

Both of these are enhancements that make it easy to browse through a movie labeling a particular kind of interaction.

There is a playback speed available under Go>Navigation Preferences. Haven't used it in a while but hopefully it still works.

I believe some simpler cases of 2. may be handled by the timeline. Eg, select a statistic from the pulldown menu, then under Go> set up a threshold for comparison, and then \<shift>-arrow (or similar) will skip to frames whenever the statistic exceeds the threshold.

The timeline stats may be customizable (eg to two-body stats like the inter-centroid dist you mention) but that is probably not friendly yet.
