Change the framerate of the sequence, it gonna help.
if you had set to "30", then change it to 29.97. And same for the "60" or "24". It worked for me and I hope it will work for you as well.

"Guys, this isn't a bug at all.

It's how NLE's were all built because they're all based off FILM EDITING where you have an extra frame to glue onto - and in the NLE, the only reason you have two edges of a 'frame' is because it's mimicking film.

THIS ISN'T A BUG - It's how every NLE works. Remove this feature and you will single handedly ***** over thousands of editors who understand how this works. If anything, just put an 'option' in the settings that a person can toggle if they want their 'out' point to actually be the started of that last frame.?"

Wrong and WRONG... Premiere didn't do this until 2020 or so, before then it and every other NLE put the out point at the position of the play head. Why in 2020 would they start adding the frame to the left of the play head to "glue onto," there's no gluing of film going on here you ****. From the time I started editing 20 years ago to 2020 the out point was the outpoint! In a NLE there is zero benifit to the program adding one frame to a clip you didn't want so that you can put it into a timeline and have the clip be one frame too long... again, not sure when you decided to pretend you knew about video editing... but for 20 years no NLE has done that. Imagine you are in a sequence trying to export between an in and out point... the in as the start of the clip, the out on the cut point before the next clip plays...you export the clip... uh oh... ONE frame of the next clip. According to you that's so I can glue something else onto that VIDEO, the VIDEO PLAYING ON MY COMPUTER???????????????? No, no it's not dummy. People literally have to subtract a frame from all their out points now for them to be correct because adobe suddenly decided to pretend Premiere was editing film on a flatbed.

This will not be fixed as it is "as designed." My recommendation is to create a feature request where you could mark out with the Playhead without having to move left one frame as an option. Media Composer has a feature where you press a modifier key when pressing Out. This "toggles" a move one left frame automatically for the mark Out. I used to use that feature a lot when I was learning MC.

I agree. This is really stupid and I dont know how, but my Premiere started to do this stupid thing after 2021 update. This is not intuitive - basically if I just jump to the end of my project and press "o" - I just add a black frame to my video.

Stupid, really stupid way to do this.

I also think that's unintuitive. You should be able to mark the Out point on what you want to be your last frame, not the one after or before. There should be an option in the settings that allows you to set the out point directly to where your cursor is, not one frame after.

I think this is a bad design and not intuitive. I press down to jump to the end of a clip so I can hit O to mark out, and it includes the first frame of the next clip.
I don't get how that's useful, however common it may be.

How many people are having to go back 1 frame because of this?

I want to export a video ending on fade to white. I go to end of sequence and hit out, but now there's 1 frame of black (nothingness) after my last frame of white. I just don't get where that's useful.

This isn't a bug, this is how all editing software works. The frame in your monitor marks the last frame within the selection.

In the timeline, the playhead sits to the left of the current frame.

It's often easier to use the Mark Clip and especially Mark Selection keyboard shortcuts. The latter especially. What I do is select everything I want in the export, hit Mark Selection, and it sets in/out points to what I want. My key for that is Shift+X but I don't know if it has a default.
