Video preview quality confusion?

Asking for a friend, for real. I have a friend who just despondently threw away hours worth of a video shoot because it was blurry and unusable. He is experienced with photography but new to video editing. I was asking some questions about the footage to see if it may be salvageable. Because apparently, it was sharp and in focus at the shoot, on the camera screen. It wasn't till he got home and opened it on his computer that he discovered it was too blurry. I wondered if maybe he shot in 1080p but tried to view it in his editor enlarged in a 4K sequence or something, without realizing the mismatch. But he said no, he viewed the clips in Bridge. I use Pr and Ae mostly, but not Bridge much, so I'm not familiar with the way it previews video. Is there a possibility that somehow some video preview settings affected the quality of the video playback? Does Bridge allow one to choose the resolution or quality at which it previews video files? Is it possible that, with the wrong settings, a decent video could appear blurry/ out of focus when previewed in Bridge? Thanks very much!
