I am always playing with different ways to create really small client videos. I got this mp4 small enough to email but it's always a challenge. I am using a lot of the Adobe Creative Suite. Photoshop (of course), Premier Pro, After Effects and Adobe's Media Encoder. It took Photoshop's Save For Web to get the GIF's small enough. It seemed to work the best. The mp4's were even smaller. This mp4 was 5mb, the gif was 6mb. While this one worked well, I'm still looking for a better way to shrink things.
