down the line

When I look back on the video footage that we've done I didn't want to actually watch the footage that we had last night, cause I prefer to look at it down the line and just shake my head and go god I made an idiot of myself or just look back and say yeah it was a good crew and it was good people, it was good times so.

here, i don't understand what down the line means. i guess the expression is "to look at it down the line".

any help on this one?
