# Why does the frame range setting behave differently when using multiple scenes in the Video Sequence Editor?

I am having trouble to understand how Render > Dimensions > Frame Range works when used together with Video Sequence Editor.

1. Start a new scene. Create 2 keyframes for the default created box at position 0 and 100. Have the box make a simple movement. Now under Render menu > Dimensions > Frame Range, set the Start Frame to 50 and End Frame to 80. Render this frame range as video file. It renders correctly.

2. Create a new scene. Use the above setup but now also go to the Video Sequence Editor and do Add > Scene > Scene to add your scene stripe in channel 0.

If you now try to render the same frame range (50-80) to a video, you will see that the rendering starts from frame 100 and finishes at 130.

If I change the frame range to 20-40, then the rendering starts from frame 40 and finishes at 60.

In other words, when the Video Sequence Editor is involved, and I setup a frame range X to Y, the rendering starts from 2*X (twice as many frames after it should start).
