At this point I'm unsure regarding the shots of the Animarium falling from the sky and landing precisely where it was a good match at on Earth.
I'm also unsure about this shot
This is probably new footage but again I'm uncertain.
Obviously once the Rangers are on the building's rooftop then I can safely say for 100% that all shots of Master Org there are Sentai footage.
I'm pretty sure this is new footage
This mysterious light is Sentai footage
More Sentai footage
This is when Master Org goes back into Sentai footage, also known as Gaoranger footage considering the Sentai source for this season
The various lights that were going around in front of the individual Rangers are all... by the looks of it recreated by MMPR Productions.
This specific light actually is a Sentai shot.
This shot of the Ratzord was actually redone from Sentai.
This shot of the Stingrayzord was also redone from Sentai because it wasn't this close in Sentai.
The Peacockzord is next however it was the last one in Sentai Now this one could have been taken from Sentai.
I also believe that this Zebrazord could have been taken from the Sentai shot as well.
These lights however were definitely redone
The up-close shot of the Red Light and Cole is just a case of another copy-and-paste job.
All of the shots of the Wildzords communicating with their human partners via the Balls of Light is also Sentai footage in some fashion. Now whether they pasted the American scene into the Sentai footage or they just simply pasted the various Balls of Light stuff into the footage, that's something that I cannot answer.
This is new footage
It then cuts to an up-close Sentai shot of Master Org which is when it goes back to Sentai footage.
New footage of the Red Ranger posing  
Once you see the up-close shot of another Ranger's glove tthen that is when it goes back to Sentai footage. However these shots of her posing are new  
Cuts back to Sentai footage once you see another Ranger's glove.
Back to new footage  
It cuts back to Sentai footage once you see Black's glove.
Back to new  
Once you see another Ranger's glove then that is when it goes back to Sentai footage.
This is when it goes back to new footage 
Once you see the Lunar Wolf Ranger's glove then that is when it goes back to Sentai footage.
This is when it goes back to new footage  
This is when it goes back to Sentai footage, with this specific shot of the Red Lion Wild Force Power Ranger
Here's various Sentai shots of the many zords 

 

Here's more Sentai footage involving the 100 Wildzords but this time they're about to unleash their beam power to strike Master Org
Once the 100 Wildzords and the 6 Rangers' beams strike Master Org, you then see a resulting reaction scene from Master Org which I'm pretty sure is Sentai footage. I can tell you the severe reaction scenes are new footage, same with the scene in which you can kind of see Adler's face in Master Org.
However once you see the Rangers then that is when it goes back to Sentai footage.
I'm sure the quick shot of the Org Heart is Sentai footage as well but no matter with that.
Here's definite new footage of the Eaglezord
