Twilight, I don't think Rainbow appreciates that...
I love doing quick modifications to things I am working on to make a GIF. A large portion of the Rainbow swing was something I made for a video and thought it would make a nice GIF. Added Twilight last minute to enhance the goofy. Also, there is no simulated physics for the models, so had to manually animate all the physics. Thought it looks pretty natural. Proud of the result. ^^
Motion blur was completely removed as I hit a wall in increasing the shutter speed to reduce it where it was either have too much or none at all. Choose to just go without.
Hard to say how long this took. The modifications to the original swing took 40-50 minutes and Twilight was about 30 minutes. That is without the time it took to create most the Rainbow Dash movements prior (spent a whole day working on the scene it is from and much more).
