Why does opt + ] trimming get me an extra frame?
Been driving me crazy for a few weeks now. I put the current time indicator at t = x, click on a layer, press opt + ], and the region gets trimmed to the t = x + 1 frame. It’s really been slowing me down as I often have regions that can’t overlap. Is there a setting I can change somewhere? Or is this a known bug? Or–please don’t answer yes–is it a feature? If it is supposed to be a good thing, how can I modify my workflow?
Thanks in advance.

Yeah, I figured it was something like that. But doesn’t that cause all manner of workflow problems? Suppose I want one layer to begin after another layer finishes. So I put the current time indicator where I want the transition. Then I click on the beginning layer, and type opt + [. Then I click on the ending layer, and type opt + ]. But I have overlap. So I have to go in an manually adjust the layer.
I’m more of an audio guy. And a moment in time has zero duration. So, when I cut, the music is over!
So if the frame rate is 25fps, and somebody wants a clip that is 2 seconds long, is that 50 or 51 frames?

After Effects is not an editing program. It is a compositing and motion graphics program. As Dave says, you gotta think like that in AE.
Two other short cuts to help you : i will display the first frame of a layer and o will display the last frame of the layer.
Select a layer by hitting the number pad number, 1 (will choose layer 1).
i will display the first frame
2 will select layer 2
Option-[ will “cut” layer two so it’s first frame will display exactly where the playhead is, and since you chose 1 and i, layer 1 and layer 2 will line up.now, for the last frames:
1
o
2
Option-]Also: this is worth the $10 https://aescripts.com/pt_shiftlayers/
2 seconds @ 25 fps is 50 frames, but frame 1 is actually frame 0, so your time line is 0-49 (in fames). And it gets more ridiculous in North America where we have fractions of frames. Video electronics are signals measured in Megahertz and we use frames as a convenience — your audio is also measure in samples.

Is there is exit of this problem/feature ?

On your timeline it will show 1 additional “frame” but your layer will not be visible if you move 1 second forward in the timeline.
When you’re hitting Opt + ], you’re telling after effects this should be your last visible frame of this layer. If it didn’t add the extra frame in the timeline then your final frame wouldn’t be visible.

It works like the inclusive out point in NLEs.

Thank you for your answer, but it is confused me when I need to “crop” several layers and then distribute them on timeline – they stuck together with those extra frames, but not inclosed – they imposed on each other and this “extra frames” are visible in preview.

facing the same problem .. and I just need an exact frame to finish and match the sequence layer… Please help somebody ?
