Oh, you don't wanna know how I do it. It's lame, but it works.
I use an old version of Quicktime and QuicKeys. When I was doing this fairly often, I had a QuicKeys routine that downloaded various shots from various cameras at their fastest intervals — usually one minute. Sometimes 15 minutes. These were sorted by name, then put in a folder and sorted by date. They were renamed in GraphicConverter with a 5 digit suffix. That covered up to 99,999 frames. Quicktime was bad about getting the order right if your numbering system had different length whole numbers. For instance, a typical sorting might go 77, 78, 79, 8, 80, 81... or 799, 8, 80, 800 801... or something like that. So, renaming them in GC assured all the frames were in the correct order.
Once that was done, another QK routine opened the folder in Quicktime, chose the first frame, set the frame rate, then Quicktime made a film out of it. When it encountered incomplete frames, it would stop, so I had to "clean" the source pictures before putting them into Quicktime. Removing those frames meant that my final movies were pretty jerky at times, depending on the reliability of a given webcam that day.
I've got dozens of them, and no clear idea of what to do with them. I thought of creating a movie as a vehicle for music, but because of the irregularity of the animations, they're really not good enough for that. Once in a while I get some cool ones, though. Here are a few:
Smoky Sunrise in Houghton, Michigan, March 2015
Watch it at full screen for best results.
Same thing, same location, 7 years prior
Same thing 11 years prior, and a mile away, looking back.
Again, full screen playback works best.
If you ever wondered what it's like to see ships go through the Panama Canal, here's a lo-res movie:
Panama Canal, Miraflores Locks, December, 2004
Even though it's lo-res, you still see much more at full-screen.
The Panama Canal video frames were downloaded by QuicKeys, at whatever interval the camera updated. Some movies get downloaded entirely by me.
Some of the movies cover 5 or 10 years. Others, a few minutes. It's just something I did occasionally for many years. Never got serious enough about it to find software for it. It was usually a spur-of-the-moment thing; I'd see something interesting happening, knowing that the only way to visualize what was interesting was through time-lapse, so away I'd go.
