A technique I use in Davinci Resolve in order to conform 30fps footage to cinematic 24fps edits. 30fps source footage is typically useful for a corporate client, but I can also convert it to 24fps for cinematic edits, using optical flow retiming and speed warp motion estimation. These are features that are built into Davinci Resolve Studio version. They are CPU and GPU intensive effects, so processing takes some time. This technique is useful when taking higher frame rate source footage and converting down to 24fps. Reducing your frame rate from 30fps to 24fps actually reduces your shutter angle by roughly 20%. So, I also show the ReelSmart Motion Blur plugin that analyzes movement between frames and is useful to bring back the motion blur and blur out most artifacts that occur when using the motion estimated retiming features in Davinci Resolve. The ReelSmart Motion Blur plug-in produces slightly more accurate results compared to Resolve's built in motion estimated motion blur. Also, on a side note that is still related to this, it is generally not a good idea to use ND filters on GoPro cameras in a situation where the camera's stabilization will be needed heavily. GoPro cameras use electronic / digital stabilization, so a lower shutter speed can show the digital stabilized movement of the video between frames baked into the motion blur. Motion estimated motion blur helps to add motion blur (simulating an ND filter) without showing stabilization artifacts. Shooting at 30fps, then converting to 24fps using this method also gives the motion blur algorithm more information to work with, so I have gravitated towards it even though it isn't very practical due to how demanding it is to process. However, it gives me the versatility and results that I'm looking for :)
