Means that's the start of the clip and I don't think you can modify it.

Thanks, how come the top comp does not have it?

Because you've 'trimmed' the clip so that's not the 'physical' start of the clip.

Hope this helps.

[James Huenergardt] "Because you've 'trimmed' the clip so that's not the 'physical' start of the clip."

That black corner will also disapper if you have time remapping enabled on the layer.

Any 'timeless' layers (solids, images, shape layers, text layers, lights & cameras) will also not have that indicator.

Hi Darby,

Thanks! That sounds more like my situation. They should be almost identical pre comps of animated text that is time mapped and has an loopout() expression. It puzzles me why one has the black diamond and is not "extendable".

I created the top one, let's call it PCA, without the black diamond and it is still extendable. Rather than recreate all the effects and keyframes,
-I just duplicated PCA and called it PCB
-changed the text inside

So with exception of the text changed, everything should be identical, but as you see it is not on the timeline:
-visually with the black diamond
-functionally in that I can't extend the PCB pre-comp
