How do I reduce frames with blending in ffmpeg

Question

I am trying to convert some files into ProRes. One fairly important part of the conversion is:

• reducing frames from 60 to 30
• blending every 2 frames

Answer 1

Simple frame dropping:

ffmpeg -i input.mov -r 30 output.mov

Interpolate frames with the minterpolate filter:

ffmpeg -i input.mov -vf minterpolate=fps=30 output.mov

• See link above as there are many additional options.

Interpolate frames with the framerate filter:

ffmpeg -i input.mov -vf framerate=fps=30 output.mov

• See link above as there are many additional options.
