secret video

[AirbusA321]

Please check if both versions are correct and which one is better.

1 I secretly made a video of random people who entered and left a supermarket.
2 I made a secret video of randomly chosen people who entered and left a supermarket.

Additional question: Can I replace "who entered and left" with "entering and leaving"?
