This isn't related to the zoompan filter. If you ask ffmpeg to not

Sorry. This is due to the crop filter evaluating x twice each frame,
since x can refer to the y expr and the first eval of x may have failed.
But even without the *crop* filter, the *zoompan* filter appears to be
starting its *in* and *on* frame counts at 3 and 2:
That should be "2 and 1"
This change occurred when zoompan switched to activate in
