I would still opt to have an option to actively enable it, as another reel segmentation
option. Maybe even 'split by content' could be a side switch for this? I think
users should have the ultimate choice to control the reel structure. A bit hypothetical,
but what if users want a strict 4GB reel segmentation due to storage media, but there is
repeat content that is larger than 4GB?
The problem is, some exotic cases may need/want reel re-use AND absolute reel size limit?
Well, maybe too exotic... But then it would be good if both would only work exclusively,
so the users notices he can only use either option.

Maybe there's two related features here:
1. use of reels to reduce DCP size when there is long still-image (or
black) content
2. use of reels to reduce DCP size when there is repeated content
I was thinking more of #2, which could probably done silently (or almost
silently). I agree that the same solution for #1 would probably be a bad
idea.
All the best,

I would hesitate to make this happen automatically, since it could
create unnecessary complex reel segmenting even when this is not
intended. I guess there needs so be some parameter that sets the minimum
reuse length, and you need to think how you deal with reel setting.
Maybe enabling this reuse feature could be implemented as another reel
option?

I was thinking about that option lately as well, basically to allow long
intermission slides, blacks, etc. with low storage needs, etc.
Currently, as others pointed out, it is not possible. When thinking
about it, I also tried to figure out how one could integrate that option
in the existing GUI. One could have a checkbox 'reuse content', and
specify a minimum length for it, so that e.g. 1min segments would be
reused.
However, let's see what Carl has to say about it. What I see from recent
bugs and bug resolving is that creating reels and keeping up with all
the increasing ambitions from subtitles, etc., this could become
cumbersome to get working flawlessly. Especially since it is only used
for very rare special applications.
It seems like a nice idea. I imagine it may even not need a UI at all...
could we not just look for areas of the timeline that could be repeated
and repeat them via a reel manipulation?
