I use JPEG for timelapse.
Life is too short.
I agree with you about JPEG for time-lapse. I was wasting so much time and space processing my raw files. It was a hassle dealing with the file maintenance. Don't get me wrong. I love RAW and it's my preferred method for still photography but the benefits for time-lapse are minimal.
For a while I was cheating and just shooting video and speeding it up in post. With my primary background and profession as a motion designer for a video production studio this is a major NO NO. However, I was lazy and low and behold one day I really needed to zoom in and catch something that I was not expecting way off in the distance. Unfortunately, the resolution was not there and I learned my lesson. Which really was not a lesson since I KNOW better than that. So I chalked it up to be a good dose of self punishment because I'm sure that if I could have blown in on this particular region of the video I would have had a once in a lifetime time-lapse capture instead of a cluster of blurry pixels.
Has anyone cheating time lapse with video ever been stuck like this before ?
