So I take a one second video every day to document my whole year then put it in an app (one second everyday) that registers the videos based on day but I took a video vertically instead of horizontally like I like them all to be. I found an app (rotate & flip) to flip the video but I didn't do it until a couple days later so when I saved the video from the app, it saved it to today's date instead of the date it was actually taken on. Is there a way for me to change the date of the video to the date I need it to be?
