Time-lapse movies:
This feature is working very well. Most recently I changed my settings to 60 second capture image with 5 seconds per hour of playing time per hour captured, resulting in a 26.5 MB daily movie file. I like this better because it seems to have eliminated the lag time when playing the larger movie on my iPhone. The movies at all settings have played fine on my iMac but the larger files have a loading lag on iOS. Here is a summary of my tested settings and the resulting file sizes so far.
File Sizes
1. 5 min capture rate, 15 sec per hour, capture image at 640x480, movie at 800x600=2.2 MB
2. 3 min capture rate, 25 sec per hour, capture image at 640x480, movie at 800x600=3.6 MB
3. 2 min capture rate, 25 sec per hour, capture image at 640x480, movie at 800x600=3.9 MB
4. 1 min capture rate, 25 sec per hour, capture image at 640x480, movie at 800x600=10.3 MB
5. Same as #4 with 0% crossfade=10.1 MB
6. Same as #4 with 100% crossfade=19.7 MB
7. 30 sec capture rate, 5 sec per hour, 0% crossfade=20.5 MB
8. Same as #7 with capture image at 12800x960, movie at 1280x960=52.3 MB
9. Same as #7 with 1 min capture rate=26.5 MB
Also, you want to set your Source image size and your Movie size to the same size for best results.
