Answer: speed it up to 120x speed. That means that every 2 minutes now takes only 1 second. I am trying hard to figure out a way to apply this same technique to my job as well.
This is something that I’ve wanted to do for a long time, ever since seeing some of the first sped-up recaps on home-improvement shows years ago. The cool side effect of speeding it up so dramatically is that it basically turned it into a stop-motion sequence of our entire project. While I didn’t capture every minute of the construction (due to having only one large memory card with me and having to dump it every 3 hours), I did manage to come back with 38 hours of video (or a whopping 65 GB for the geeks out there.) Working with so many large clips proved problematic for editing, so I spliced each day’s together into a single, uncompressed movie sped up to 12x real time Once I had the four intermediate clips, I then sped each up to as much as an additional 10x. There are a few places where I kept the speeds lower to better emphasize a portion of the video.
Was it worth the time to do? Probably not. But I can’t think of a better way to immortalize the time we spent building that thing. To see the best quality, make sure the change the video from 360p to 480p.
