Hey @anura16! You've come to the right place for a bit of feedback
I took a look at your landing pages, and now I have a major case of the travel bug! You've got some great materials to work with here, but I have a tip that might help drive some more conversions.
I think your CTA needs to be a bit more prominent on these pages. Right now, your "Get The Brochure" button is below the fold, and if the users scroll quickly down the page, they may miss it altogether.
In order to create a strong CTA, it needs to be clear what you want the user to do. In this case, I would suggest throwing a slight overlay over your video. Not to cover it completely, but to help make the CTA jump out a bit more. Since you've got more images and video on your pages, it won't hurt to edit the video background a bit. Then add your CTA in the center of the page to draw even more attention to it.
Here's a screenshot explaining what I mean:
Do you have insight into how many of your viewers are mobile vs. desktop? Video backgrounds only really help to convert on desktop (as they aren't functional on mobile).
That's what I've got so far, but I'd be curious to know what our @Unbounce-Experts have to add to this.
Let me know if that helps a bit
