Create a movie from the game screen based on Vuforia and share it

Hello! I want to create movies or still images from the game screen synthesizing Vuforia and 3DCG characters. And I want to allow users to contribute to Youtube etc.

1. The combination of Vuforia and Evryplay is the best. But it seems that reputation is bad. Is this combination impossible?

2. The combination of Vuforia and reK - iOS ReplayKit Plugin appears to be possible. The problem is not covered by Android. Is there anyone who tried this combination?

3. The combination of Vuforia and AVPro Video appears to be possible. But it seems that trouble is also reported in the forum. It does not seem to be solved. Is there anyone who tried this combination?

4. What should I do with still images? I can not clear the problem. I would like to install both the camera button and movie recording button if possible.

5. Do you think Vuforia is the best? Is there anyone who tried other Ar?

I am a designer and I'm not used to Unity yet. I appreciate any information!
