you might also consider having a look at the timeblend HDA that ships with houdini.
I believe the chain goes file->timeblend->time warp. IIRC you need to disable 'integer frames' on Mr. timeblend.

Once you are reading stuff off disk, Houdini has no way to know what
is happening in between frames - unless you set it up yourself.
You need to interpolate between current frame and previous (or next)
frame using 2 file sops and a blend sop. In one of the file sops use a
regular $F expression - but in the other you will need to use `$F-1`
or `$F+1` and maybe padzero if you use $F4. ie. `padzero(4, $F+1)`
Then in the blend you need to put a sawtooth expression in the blend
