It would speed up rendering of large projects by just copying the source video for all clips that don't have effects applied to them, and allow KDEnlive and MLT to have even higher-quality output if the video doesn't need to be re-encoded.  Just an idea that I've heard mentioned before.  More here (couldn't find it in Mantis tho):

This is not trivial at all and since it is rather deep into how MLT
works and will require touching nearly every MLT module, I do not
think it is good for SoC. Something that is more add-on is better.

Also, this whole idea of passthrough is very tricky for the user to be
practical. The UI will need a lot of work to help the user from doing
things that will require rendering when perhaps they did not expect or
want so. All of this is an immense amount of work, and it is
increasingly less popular IMHO because more often than not you end up
encoding to some unrelated format in the end. Therefore, it does not
have a great return on investment, especially when compared to other
things on the ToDo list.

I agree with this, but I am also optimistic that it can be addressed
before the end of SoC.
