Import the footage into After Effects. Bring it into a comp and change the speed of the layer either with the speed control for the layer or with time remapping. Make sure the layer has Frame Blending turned on, and that it's on for your final render. Frame blending will blend all of the frames that make up a single frame, so if 20 minutes makes 10 seconds ...

Assuming these have, or can be given, consecutively numbered file names you can do this easily using ffmpeg, avconv and similar utilities. Most have builds for Mac, Windows and Linux. The choice of frame rate is up to you, and really affects only the total length of the output file (at 30fps, 280000 frames is 2.6 hours; at 24 fps it's 3.24 hours). If you ...

Mask (and feather) around the subjects, so the surrounding is moving quickly, but they are breathing and blinking in normal time. Slightly crazier idea: Track the parts of your subjects that ...

I've done this a couple times. My software choice is VirtualDub (free), and then After Effects for some cleanup (stabilization). The stabilization can be done by YouTube if you don't own After Effects. Basically just download VirtualDub, then import the image sequence into it. It'll automatically import all the photos after you select the first one. Make ...

The problem isn't the remote timing, it's the rate at which data can be written to the SD or CF card. The camera can shoot a bunch of images quickly in burst mode because it stores them in an internal buffer for a short while before it writes them to memory. However, this pace of data acquisition is not sustainable for long periods of time because the ...
