Forgive me if this elementary question is coming way too late. I can not seem to find a way to clear or remove IN and/or OUT points in Kdenlive. Can someone help explain this to me?
Hi @Jerry_Earley, and welcome to the forum and community.
You can set them using I and O or by clicking on the respective button/icon. If you create an IN and OUT at the same position, it is essentially cleared/removed.
What is your use case exactly?
Thank you for your very fast response. I appreciate the time you took to respond. Being an old guy with his start on an old tape to tape convergence editor, I like to edit with three points rather than flood my timeline then trim. So sometimes I need to clear an IN or an OUT to reset an edit. Is there a work around if there is no clearing IN’s or OUT’s?
Have you looked at the docs on 3-point editing?
Is there something you need that isn’t described there?
For the kind of projects I normally work on, this hasn’t been a workflow I’ve gravitated toward, but I know we have some working professional editors using this, and support for this was designed under their advice - so I’d have guessed it was feature complete for that use, but if it somehow isn’t we should look at that.
[edit: the following is from one of the people who drove the current implementation design]
Our system has 1 basic difference: we don’t have IN OUT points for 3 points editing and IN OUT to set the rendering area.
In Kdenlive we use the same object for both functions. For this reason we have a button to enable/disable the timeline zone for the task. Instead of removing the reference points you just disable the zone use. This has the advantage to preserve a set area and be able to work on the edit-line/cursor reference only without the needs of cancelling the zone as it is not actually possible.
Hope that helps, but if you still need more we should discuss it further.
I will add that a simple “Clear In and Out” is something I looked for as well.
I used I/O for measuring segments from time to time and then I just want to “clean up” and make them go away. Premiere has a right-click “Clear In and Out Points” which makes this function trivially simple.
I appreciate Ron’s posting of the methodology of zones, and will admit to reading through it “to preserve a set area and be able to work on the edit-line/cursor reference only without the needs of cancelling the zone as it is not actually possible…”
and not having a clue as to what I read.
Maybe I’m just old-school. 
We should probably get you guys together with @massimostella at the next Cafe to hash out the differences in how you each like to work, see if there is anything we can or should tweak about how it works, and maybe put together a little demo of how professional editors like to work in this way.
and then I just want to “clean up” and make them go away.
They aren’t “in the way” in any way if you aren’t actively using them though are they? Is this just visually distracting for you or something else?
I don’t really edit in the 3-point fashion myself, but I do fairly regularly use the zone for measuring and marking areas I want to do a preview or partial-timeline proof render of or the like. And I can’t really say I’ve been annoyed by them “being in the way” by just being wherever I last used them, and sometimes that is useful. But I feel I’m missing something about either the way you guys are working or what you are used to seeing, and I’m not sure exactly what that is yet?

I’m not using them to “edit” per-se, but rather to measure time between here and there, and then when looking at the timeline later, it can get confusing when I expect to see the total program length and it’s still showing segment length, and being able to just right click clear the segment I/O shows me total timeline / program length.
Hmm, perhaps the Timeline Markers with Range (new in 25.12) can do the trick?
Ok, then that’s a bit different to what we were originally talking about after the OP’s second post to clarify what they were really having trouble with - which explains why the response from Massimo that I quoted didn’t make a lot of sense to you : )

And … now I’m confused about what you are looking at!
There’s the timecode indicator in the timeline toolbar that shows current pointer position and total timeline length. And the separate popups that show the endpoints and duration of the zone when you hover over it.
What indicator are you looking at that is confusing?
Is this one of those things where we have some indicator that looks a bit like an indicator from some other app but reports something different, or am I just missing something here still?
