So I have Adobe After Effects CC 2017 and when I'm editing I don't see my videoclip that is edited, but I see a clip what was in the beginning (without any effects etc.)
When I render - clip have all effects and stuff...can I do something to make that I can see what I'm doing?
Moved your post from Forum Comments to After Effects forum.
You're looking at the Layer panel.
Just go to the window menu and click in composition.
If you accidentally double click a layer, it will open the Layer Panel, which looks very similar to the Conposition panel. You should see the Composition panel next to the Layer panel tab, just click on it to open it. Or double click the composition in the Project panel.
hope this helps
