Why do the videos I make start randomly into the video, and not at the beginning?

This is the "TV" effect where all videos begin playing when the unit is turned on. You can turn off the TV mode using the settings menu, tutorial here: https://learn.tinycircuits.com/Kits/TinyTV-Tutorial/

Turning the TV mode off will turn on the Video Player effect where you cycle through the videos, play/pause each individually, and fast forward or rewind. You can also turn on Auto Play and Loop to loop and play the videos automatically at start up rather than needing to select a video to play it.

I hope that helps!

Thanks,
