Long paused frame at the beginning of mp4 (pictures)

^^^video settings

^first viewable frame (can’t scroll any further to the left)

  • there are 12 total frames in this video

What is the big gap at the beginning of the video? It’s only a 1 second clip. But the first 20% or so of that clip is one frame. the rest of the video, the frames are pretty consistent (meaning equal intervals between all of the rest). Why is this happening? is there something i could tweak about my settings to mediate this?
