Typically when you want slow motion from a DSLR / Mirrorless camera you shoot in 60fps and conform it down to your 24p/30p project. It's a bit different with the new GH4 and as someone who doesn't read user manuals, selecting these new framerates on the GH4 was just a little confusing so I thought i'd share this video.
By choosing 96fps VFR will give you 25% playback on your 24p Recording Frame Rate for slow motion. Choosing 2fps VFR will give you 1200% playback on your 24p Recording Frame Rate to simulate fast motion. Fast motion is a great option. Instead of doing interval Time Lapse images that have to be stitched in post, the GH4 will save the entire sequence into a single video file. Very fun feature that opens up more creative shooting options when you're out and about. Stay tuned for more GH4 tips.
