Wow. Thank you so much @artemislives for the offer and your wonderful comment. Would love to visit you next time we are in Thailand. We went there for our first anniversary but we will visit again soon. :) And I will surely ask @hungryhustle to make a post about the tech we used. He should better be creating a video about it, hehe!

Well, tbh, we shot the video on his phone and a microphone to record voice which we bought on Amazon, it was very cheap as well. You have to use a small tripod also to place the camera or phone. That is also not very costly. But still, I will ask him to send you the details separately as well.
