Your video length is determined by the number of images in your video and the length of your song.  Here's a few things to check if your video isn't turning out the way you'd hoped:

2. Adjust your video speed

You can choose the speed at which images appear in your video. This is really useful for getting the feeling of your video right, and also for getting more images for a given song. Here is how it works.

To change the pace of your video, move the pacing slider to the right or left:

Do you have pictures that just won’t fit into your current song? If the video is full, move the pacing slider. You’ll see the following when you save:

Drag your images into the video & produce!
