Blender VSE and Node Editor

Hi, people!

I have three simple (noob) question (I think…):

  1. Can I make animation with Blender Node Editor values? I tried to create a keyframe to Hue value on “Hue Saturation Value” node and work a little on Curves, but these changes seem to do not affect the render.

  2. Can a video added as Node start not on first frame. I already tried to change the values of “Start Frame” and “Offset”, but all movies that I add to Node Editor starts always on same time.

  3. The last: can it combine the powers of Node Editor and VSE? They seems no afected each other, am I doing some wrong?

Can somebody help me?

Thanks a lot!!
