> If you happen to want a cut just 20 frames after a keyframe, those 20 frames could be computed (decoded) in order to create a new keyframe right in the spot you wanted.
All the P-frames and B-frames in between two I-frames have to be recomputed. That’s by definition re-encoding and not lossless.
You could re-encode just that small segment though.
