Also not an expert, but since videos are transcoded as key-frames and changes applied to those key frames, I don't think it's as simple as segmenting something like a CSV. Transcoding is probably required just for the segmentation process. Putting it back together might be easier, but the final output file might also be larger because of overhead.

The segmentation code is keyframe-aware, so it only splits along keyframe edges. In other words: requesting segments of 30 seconds each probably won't get you segments that are exactly 30 seconds long. Still, there could be plenty of other obstacles I'm not aware of.
