Questions & Answers about ie de douga o mite bakari iru to, shukudai ga owarimasen.
で marks the place where an action happens.
- 家で = at home
- The action is 動画を見る (to watch videos), and that action happens at home.
If you used に here, it would sound like a destination or existence point instead, which is not what this sentence needs.
Because 動画 is the direct object of 見る.
- 動画を見ます = watch videos
- を marks the thing that the action is done to.
So in this sentence:
- 動画を見て = watching videos
