I was re-looking at this scene, and while I agree that the first portion possibly grinds the film to a halt, I firmly believe that all of it should be included.
With that being said, how about possibly adding in a background music soundtrack that is fast paced and seem to keep pushing it forward. Also, possibly take some other "hulking out" sounds/growls from other Hulk/Avengers movies and add them to the background. If need be, alter these hulking out sounds/growls so that they seem like they are his inner voice and that would coincide with the video footage that seems to show Bruce fighting the inner demons (as opposed to the controlled rage at the end of the first one Avengers movie). I think adding a fast paced musical soundtrack and inner hulk sounds would solve the issue of the movie grinding to a halt.
There is also the possibility that just as the scene is about to change POV from where he is in the jungle to the town nearby, you could have a growing (as in decibel/loudness)/echoing Hulking out sound culminating is a full out Hulk out growl as it spreads across both scene bits. This would signify Bruce loosing out to those inner demons.
Maybe something with fast paced drum, such as from older Tarzan movie or better yet, the music with drums from Peter Jackson’s King Kong when the natives were going to make the human sacrifice of Ann to Kong. That would be perfect I think.
