I think Abhishek Sharma is on the right track. However, I also think the following isn't clear:
When I look at the above, it's now clear to me that I've selected Create a live photo, but it's not clear to me what the Video | Photo option is for? I guess it wouldn't take long to figure out, especially if you're using it, but I do feel it's missing something.
Maybe it'd be better to step the user through it. You could have a prompt like "Choose your action" or "What would you like to do" or something similar. Then your next step would be "Choose your original" or something similar.
This approach doesn't necessarily have to be split between screens (although you could certainly do it that way - Step 1..., Step 2..., and so on).
Also, the actual user selection between Video or Photo isn't clear - that is, it's not clear which one has been selected by the user. Your best bet would be to clearly change the appearance of the selected option. For example:
In the above mockup it's clearer to the user they have selected 'Photo' because the text PHOTO is now a distinct color away from the black and white theme, and it's also in bold and larger point size.
You don't have to use yellow, or even change the appearance of your text, but you probably should do something to differentiate what the user has selected. If you go with Abhishek Sharma's 'triangle' you could also use that instead to show the selected option.
Either way, I think we've been able to help you make your app clearer for users. Good luck with it! :)
