Once Wes, Jen and Eric's morph sequences end, it then cuts into the Sentai footage which is the first time that it's been in Sentai footage in this ep.
These shots   are when it goes back to new footage.

Once you see an up-close shot of Mr. Mechanau's DNA patch then that is when it goes back to Sentai footage.
All Giant footage is Sentai footage.
The sequence in which the Strata Cycle is brought onto the launchpad as well as being catapulted down the runway by the Trans-Warp Megazord is all footage that is strangely cleverly edited.

Sentai footage (despite somewhat limited within this ep) comes from Time Episode 41
