Theta-S is great for taking time lapse videos, but could be better. I would suggest 3 improvements:
1) phone app should allow you to enter bigger frame counts than 200, the cam supports thousands.
2) cam firmware should have a "raw" mode that stores unstitched images at full resolution. That would likely support capture at 3-5 frames per second.
3) PC software that can stitch and level a whole batch of images with one click. This should use the same leveling rotations and image warps for all images, so that there is no "shake" or "crawl" when they are shown as a video. Some stabiliztion of exposure and white balance, based on moving averages, would also be valuable.

Here is a sample time lapse shot with Theta S at 8 sec/frame, auto exposure, auto white balance. The frames were leveled individually based on the metadata, and you can see what looks like camera shake but is probably sensor noise. There may also be some "crawl" at the base of the sculpture, due to the stitching warp varying with image content, but this is comparatively minor. Color and brightness fluctuate noticeably too -- that might have been avoided by using fixed exposure and white balance (the lighting was perfectly steady during these 16 minutes).
