For some reason, certain pictures are importing into Motion with a length of only about 1 second. And I can't seem to make them longer. Meanwhile, other pictures/images come in just fine and are completely adjustable. In addition, those images I can't seem to adjust, seem to be multiple images. So even though, the thumbnail in the motion sequence is the image I imported, if i scroll through my one second of image, its actually multiple pictures. I trashed my preferences, i even reinstalled the entire program...still the same result. Any idea whats happening?
It sound like you might have brought in an image sequence, by accident. If you have a bunch of files with sequential names, like filename001.png, filename002.png, filename003.png and so on, Motion can collapse them and allow you to bring them in as a clip (image sequence). Treated as a clip, it would have a maximum length, etc.
To make sure that you're not bringing in an entire sequence, just toggle off the image sequence filter button in the bottom-right corner of the File Browser. It's right next to the Add a New Folder button.
