After choosing the clips, I edited them using Premiere Pro to form a 1 min video with only ambient sound and a bit of natural sound.
Due to the short time length of the video, some of the clips that are meant to be used have to be taken out, especially the night scenes, as I realised I am not able to form smooth sequences if add those within the timeline of 1 min.
It is indeed proving to be a challenge to create good clip in such short time duration but overall I pretty like the process and the challenge it gave me. XD
Below is the completed clip:
