Hi
I think we need to clarify what you mean by the word "sequence"
In the normal sense it is a series of individual video clips placed in order on the timeline.They are not linked in any way apart from their chronological order.
However, from the standpoint of VP a "Sequence" is a collection of clips/images/effects etc. that you have edited on the timeline and which you have converted to a SINGLE CLIP using the option "Sequence" and "Add"
VP creates this single clip and places it in the Sequence Bin. This now is a Sequence.
Following this procedure the timeline is cleared for further editing.
Sequences then, are single clips. They can be placed on the timeline like clips. i.e. You can add a sequence to another sequence on the timeline and further edit them if required. You can split them and insert them. In nearly all respects they behave like individual clips. You can even create new sequences from them. (Although processing these can take time).
From the exporting point of view. (I think you mean Export when you say "Print" they behave like normal timeline clips.
If you place Sequence 1 (made up of lots of CLIPS) on the timeline you can export it as normal to make a video.
You can then clear the timeline by deleting Sequence 1 from it . (Don't worry - It will remain in the Sequence Bin)
Now place Sequence 2 (made up of a lot of clips) on the timeline followed by Sequence 3. (made up of a lot of clips).
You can export this combination of 2 sequences (just like 2 clips) to produce another video.
Video 1 will be Sequence 1
Video 2 will be Sequence 2 followed by Sequence 3.
Hope this clarifies things a little
