Can't add more than one title over single clip

Question

This is the first time I'm using a clip that is unedited apart from a title card over black at the beginning that dissolves into the clip and a dissolve to a still photo at the end of the clip.  So far I have only been able to add three titles: the first over black, the second over the actual clip, and the third over the still photo.
The clip lasts around a minute so I want to add titles as it progresses.  For example, the first title can last for 5 seconds, then a gap of 10 secs. and then another title for 5 seconds, etc.  Every time I try to drag the title
Every time I try to drag a title into the project, it doesn't "take."  Does iMovie not allow a string of titles if there are no edits within the actual clip?
Thanx.

Answer 1

This applies to iMovie 08:
1) It appears that when you drag a photo or a title to a long clip, then by default, it thinks you want a long photo (or title). It seems like it wants to make the photo 25% or more of the length of the clip. This is why it is hard to drag multiple photos to a clip. The last photo you drag is trying to take up 25% plus of the clip, and there may not be room.
I found a good workaround. I added a dummy clip that was 4 seconds long to the end of the project. (This clip to be deleted before sharing the project). When I drag a new photo to the project, I first drag it to the dummy clip. Now the photo has a duration of exactly four seconds, and I can drag it to the place I really want it. It fits now, because it is only four seconds.
2) I confirmed that when you put over 4-5 photos into a single clip, they will start behaving erratically. One will not show up, and another will show up twice.
The solution is to split the long clip into multiple clips. I had a long clip. I split the long clip into 30 second chunks. To do this, I imported the entire clip several times. Then, in the first instance I selected from frames 00:00 to 30:00. In the second clip I selected frames 30:01 to 1:00:00. Then 1:00:01 to 1:30:00. etc. This way, I did not lose any footage, but I had multiple virtual clips, where before there was only one. Now I was able to add multiple photos to each of these shorter clips with no trouble. And I only needed four photos per clip. It worked great.
