This is the sample file:

The AVS isn't used for HEVC prediction because the SelectRangeEvery() filter just doesn't seem to be able to find keyframes on HEVC. You also can't look at the M2TS used as input because a player (but not an encoder) will have trouble with the crazy DTS/PTS values.

You pretty much have to look at the output of the prediction to actually see how it went.
