Panasonic GH4 Series Part 6 Slow Motion
Fjolnir Baldursson just corrected me.
To save some steps just put your GH4 on 1920x1080 23.97p VFR Available and Variable Frame Rate at 96 instead of 1920x1080 29.97p VFR Available and then to make it real time in After Effects right click the clip and Time/Time Stretch/ 24.
It looks like the Vimeo upload screwed up the colors in my face. I just checked the original and it look perfect. What the heck.
I would love to hear from you guys and gals follow me:
Who doesn’t like slow motion, well at least when its not over done. That’s another cool thing about the GH4 is that you can film at an amazing 96fps and the camera will process the slow motion in camera so you can view it right their on the spot to see if the action looks the way you want it to. But what about if you want to do time re-mapping and get the footage to be at real time then slow down and speed up again. In this episode I show you how to not only get the slowest smoothest slow motion but how to speed it up to real time and slow it back down to its slowest with only using After Effects and no plugins or frame blending and without skipping frames which leads to choppy slow motion. The only downside to using slow motion at 96fps is you can only do it at 1920×1080 not 4K. Also the quality is not the best at times. But the average viewer who is not pixel peeking will never know the difference. Also when switching to slow motion a shutter speed of 100th is the lowest you can go due to the high frame rate so you will need more light in your scene then filming at the normal shutter speed of 50th. One thing I did not talk about in the video is if you want less motion blur and have enough light in your scene you can crank up the shutter speed to 150 or higher but I find keeping shutter at 100th looks natural so I keep it their.
The intro slow motion piece I did was done super quick so quality is lacking. I went to the beach but did not find to much fast moving things so then I headed over to a local skate park where their were a few guys skating that were nice to let me film them doing a few jumps. So a Big thanks to those sktateers.
Filmed the slow motion and me with the Panasonic 20mm f1.7
