i understand that this is the fastest way to extract frames, but it is limited by key frame availability in the original file (i.e.) you can only start the output from a keyframe.
in this case, it is important to be aware that the times you specify may not be extracted exactly. it will be off by a few frames based on keyframe availability. the only way to extract exact frames is to re-encode. :)
