At the top of the panel, you can find the list of sequence. The currently selected sequence is highlighted in the list. The IMPORT button opens the import screen. With this button new sequences may be easily added to a project.
Right clicking on a sequence button shows the popup menu. From this menu, the sequence can be removed or be moved to another position in the project.
The bottom of the panel shows all of the frames and allows you to change the frame per second rate of the currently selected sequence.
By default the sequence frames list is collapsed and shows only a few frames from the sequence.
To see all of the frames in the sequence click the Expand button right after frames.
Right clicking on any frame displays a popup menu. The menu contains the following items:
It is possible to create a "sequence" from a single still image. This could be useful for showing captions before or after the video. The duration setting is used instead of the FPS rate for sequences of this kind because the frame rate value does make sense in the case of a single frame. Right click on the IMPORT button to add sequences created with a single image to the project. The popup menu is shown with the Add Single Image item. Choosing this item displays a file dialog to open the image file.
