Gaggle of Geese Remapped

During a recent shoot with a Canon 7D at Columbia Lake in Waterloo, Ontario, I chanced upon a small gaggle of geese preparing to take off. Although I was shooting in 1080p at 30 frames per second, I tracked their launch although I would rather have been shooting at the faster frame rate of 60 fps (albeit in the lower resolution of 720p).

This resulted in approx 10 useable seconds which I plan to incorporate later in a feature I'm creating about this park. A timely "tweet" by @AdobePremiere pointed me to a CS5 Help File at help.adobe.com on Timeline Remapping.

Here is described a very simple technique, which I've employed before for "Winter Sparrows", in which to create slow motion of the geese in flight by remapping the timeline. Slowing down to 25% (7.5 fps) of the original 30 fps framerate does create a slight jerkiness in the panning, but the wing motion actually remains quite smooth. Next time I WILL shoot at 720p/60 fps so that the resultant slo-mo frame rate of 15 fps (ie. 25%) will be smoother overall.

Thanks to @AdobePremiere (follow him on Twitter -- lots of useful tweets daily!)
