Start and End frame for Animations

Ok how can i set the start and end frame for each animation ?
Because if i set it in the timeline panel it only effects the scene.

For example i create my animations in the Dopesheet and then i the graph-Editor i want to add the start and end frame for my animation.

I saw in the tutorial where i need to set the Start and End frame it was i black line.
Here is the Tutorial

Appreciate any help.

In the Dimensions panel of the render tab (of the properties editor), choose the Range of Frames to use.

Thats the Rendering Frames so you are confused or something.
I just want to Set the start and end frame of each animation some are shorter and some longer.
So how can i set the Animation start and end frame ?

do you mean the length of an animationstrip in the nla editor? that can be done by pressing N in the nla editor do bring up the settings for the selected strip. There you can set the strip and action length.
You don’t have to define the start/end frames in grapheditor/dope sheet, you simply grab the first/last keyframe to the frame you want.
