BUG: Video datasets only converting to frames when fps = none

[rcho5840]

Describe the problem

I have a video recorded at 30 fps, 1080p from a webcam in mp4 format. I am trying to convert this video into frames and then take the 100 most distinct frames from the video. Given that the video was recorded at 30fps, I only want 1 frame per second of video, but the to_frames method will not actually save my frames to file unless I leave the fps parameter empty.

Code to reproduce issue

My code:

What happens when fps = none (works as expected):

Note that I have no idea why it says "Setting 63984 frame filepaths on the input collection that exist on disk but are not recorded on the dataset" because it is saving 63984 jpgs to a file path which I definitely do not want

What happens when I put fps = 1 as a parameter in to_frames:

It isn't able to write to a file even though I was able to write to file when fps parameter isn't adjusted
