No you certainly wouldn't. Watch the technical video at the bottom of the page. It will explain why this is not trivial to do and why standard stabilisation technologies aren't useful to smooth out time lapses.
- boyaka 12y agoWell, I admit that I was pretty ignorant about the work being done on this project in regards to time-lapsed video. I guess I could add to my previous statement that they also cut out irrelevant frames (parts of the video that aren't in the camera path). I don't think this would be THAT difficult to do manually, but I admit that the technical video showing how they were able to graph/visualize the irrelevant frames is pretty cool, and the interesting resulting effects people are discussing in this thread (disappearing/appearing objects, the video game loading effects) are amusing. I never said that it was trivial, just that similar stuff has already been done and made a "standard stabilization technology", automatically and easily just by uploading to youtube. It seems that youtube's techniques aren't necessarily completely different: there's a screenshot of an article from Google in this video [1] called "Auto-directed Video Stabilization With Robust L1 Optimal Camera Paths". However, I do appreciate and shouldn't disrespect the specialized work being done for time-lapsed videos. My apologies.
