Timeline length

I came across the same problem when embedding videos. The timeline was as long as several thousand seconds which took minutes to drag back to .25 seconds. Tea Tavanxhiu's solution seems to work when embedding new content. If you embed it while in the states tab it goes to a default of 5 seconds. But I already had 100's of videos embedded when I realized the problem.The solution to the dragging problem is to start dragging and then press the left back arrow on  your keyboard. This will jump you to the beginning of the timeline. Then put your mousepoint on one second and release the mouse button. Viola! You just saved agonizing time scrolling all day. Hope this helps others!
