GH3 video settings
Feb 5, 2013

I have just received my GH3 and I am getting lost in video formats. Have done a bit of research on different formats, including some Canon forums and here are a few conclusions:

- Generally, higher bit rates are better, but many people believe that IPB at lower bit rates are superior to All-I at higher rates. This opinion comes mostly from Canon forums based on lower overall bit rates than with GH3. Has anyone done a direct comparison of 50mbps IPB vs 72mbps All-I in GH3?

- All-I is supposed to have an advantage in shots with a lot of motion, because it records every single frame. The irony is, though that rapid motion is better recorded in 60fps 1080p, but GH3 doesn't store it in All-I format. So, there are a few options for fast motion, such as sports in GH3: 60fps/1080p in IPB, 60fps/1080i in All-I, and 60fps/720p in All-I. What is a better choice - any ideas?

- I will be working with the files in Final Cut Pro X, probably transcoding them to ProRes 422. Will there be any difference between All-I and IPB after transcoding?

Any input is appreciated.
