Creating a 10-hour video from a 60-second clip

Call me old-fashioned (been doing this since 1992) but I'm always a bit confused when I see posts about exporting out 10-hour video clips since most video programs are 1-2 hours, who actually watches for 10 hours straight? There has to be a better way, one would think. Like LOOP in the player? Especially since it's the same 60-seconds over and over, why create a 10-hour clip? How big is that? How will it be played/viewed? Maybe I'm missing the point - could be art ;-)

So you don't want a jump every 60 seconds, so make a 1-hour clip and loop in player and have a jump once an hour. Or, I was just given an animated background (15 seconds) that I need to be looping for a LIVE broadcast event tomorrow. But not being created as a looping animation originally, the image jumps when repeating. I cut a few seconds from the beginning, pasted that material onto the end, and put the cross-dissolve there, and exported that edit. When loop playback goes from last frame of my new clip back to first frame, there is NO jump or interruption this way, as the frames being played at end then into beginning again are sequential as they were in original clip, if that makes sense.

Another tip, if you must export 10 hours - create say a 10-minute timeline sequence with your dissolves in it, then EXPORT as ProRes. Then bring that new ProRes clip into a new sequence and repeat it a bunch of times, then export again as the longer version. That may take better advantage of smart rendering. And I have no idea what format your source clip is, what effects might be applied, but in general I think with the nature of what you are doing it would've been easier from the start to do something like that rather than paste 600 instances of the same clip.
