Ps Timeline window question

[chris701]

So if I create a video layer then I start drawing some 2d animation on it, everything ok, but now let's says I would like the first part of the animation to last longer, so I trim the video layer with "Trim start at playhead", then I get a piece of that video layer on a new layer, now if I drag this new piece of video layer to make it last longer the forward trimmed part shows up, I dont want that I want to completely trim the video layer, I have attached a picture to help.

That's not how it works. You have to manually delete any extraneous keyframes. The representation on the timeline is a container with additional data streams for keyframes and so on, not an absolute reference. That's what "non-destructive editing really is and it would not really be different elsewhere, even if some animation tools have a "dope sheet" mode that represents both the image data as well as keyframes and such as stacks of boxes/ bars where to some extent this kind of hard cutting is possible, but only if you explicitly enable it.

I'm using two 2d animation software: TVpaint and OpenToonz, in these software when I trim or delete a part of my timeline it behaves the way I want or wanted in Ps, Ps timeline is just an addon and not a professional tool.
