HI
When VP opens there will only one empty track; Video Track 1.
Load a clip or clips to VP (Add a File) and theywill appear as a thumbnails in the clip bin area at the top left of the screen Drag or more clips from here to Video Track 1 where it will display. You now have a singe track timeline which you add further clips to and edit.
With a clip on Video Track 1 you will now see a black zone above the track with the words Drag and drop your video;text and image clips here to overlay. If required you can add (drag and drop) clips from the bin to this zone. This will create Video Track 2.
Above this will be a further overlay zone which will become Video Track 3 and so on. Note that clips etc on the upper track will obscure clips on the lower tracks.
You need to select a track first before the Menu/Track options are active. Until you have done this the sub-menu will remain greyed out. Select the track by clicking it at the far left.
