New footage

Sentai

Obviously the shots of the Golf Balls hitting the Rangers is Sentai
footage however you will see what I believe to be reused Sentai footage
for the Red Ranger, Yellow Ranger and Blue Ranger as they're flying in
the air due to the force of the blast that hit them.

These shots on the Monitor

This is also new
The transformation Sentai stock footage to Super Dino Mode is as I said
Sentai footage but once it ends, it continues in Sentai footage but
regular Sentai footage.
I believe this shot
is Sentai footage but I believe they've
pulled it from a previous episode.
Here's Sentai footage that is back to Abaranger 33

Hydro Regenerator Rain Cloud is Sentai stock footage as in the
Brachiozord stuff and the combination sequence. Once you see the Giant
Thornox is when it goes back to regular Sentai footage.
NOTE: All Sentai footage comes from Abaranger 33 except for stock
footage and the one reused scene where Red in Super Dino Mode and the
White Ranger are fighting.
