Hi
You probably need to change one of the "Options" settings. (See below)
The first step is to load all your clips to the media list window using the "Add Media" button on the tool bar. (I am sure you will have done this
) Your clips will then list up in the window on the left. If they dont then click the tab marked "Media List"
The next step is to get the clips from the list onto the the sequence line. You can do this in two ways but first of all set the program options as follows.:-
Left click the "Options" tab on the toolbar followed by the "Other" tab. In the box prefixed by "Add new clip to the following position" select "Ask me" from the drop down menu. Now click OK. This will ensure that if you add clips directly from the media list you will be prompted as to where you want them to go. I am thinking from your post that this has been set to "Beginning of timeline"
Now, to get the clips onto the sequence...The simplest way is just to drag the clip in question from the media list and drop it directly onto the sequence track. You can drop the clip into any position relative to the clips already there. If you drag your new clip left or right along the track a pink arrow appears over the junction between existing clips and that is where your new clip will go when you drop it.
The second method is to right click the clip on the media list and from the menu that appears select to "Add item(s) to the sequence". If the clip is the first clip to be added it will appear immediately. If otherwise you will now be prompted as to where you want the new clip to be placed. (As you have set the options to "Ask me".) If you happen to select "Sliders position" your sequence will be split for the new clip to be inserted. You would normally select "End of timeline" in order to build up your film in the correct playing order. (Left to right)
Note that if you have a clip on the sequence in the wrong place (Say, you missed one on the list and it's been added at the end of the timeline,) you can simply select it and drag it along right or left to the correct place where a pink arrow appears and then release it.
Hope this helps
