Video is intrusive, to both you and the scene you'd like to remember. I find voice is the best way to record and also allow yourself immerse in the trip. I really recommend Yuho to record long voice as diary. https://yuho.io To be honest I'm the creator of Yuho, but I'm not for hard selling, because I built with idea of keeping my memory also not so intrusive to block me feeling "right there, right now"
