How to Extract Key Frames from A Video with FFmpeg - jdhao's digital space

In order to get enough information from videos, we often need to extract video frames. However, we do not want to extract every frame from a video due to: information redundancy in successive video frames. huge storage space needed by these video frames. In this post, I want to share how to extract key frames from video to reduce the storage, but still capture enough information from a video.

Awsome - though, once youhave the timestamped keyframes, can you rebuild the mpeg from it ?

[jdhao]

@dmaugis, yeah, maybe, by concatenating the key frames?
