Image Sequences

One of the most powerful features in OpenShot is the ability to import sequences of images. �A sequence of images is really just a folder full of images that are named very similar, and of course named sequentially. �Each image file represents one frame of video. �So for a 30 second long clip, with 30 frames per second, you would have 900 image files. �Although image sequences can be tough to work with (because of the shear volume of files), it can do just about anything.

To import an image sequence, follow these steps:

Locate an Image Sequence

Many programs can generate an image sequence. �For example, in Blender (a 3D animation package), you can create a great animated title sequence and export it as a series of named .PNG files (with transparency). �It will create a folder on your computer that contains all of the image files.

Import the Image Sequence

Choose the File > Import Image Sequence menu option, and that will launch the Image Sequence dialog. �

Choose the folder location of your image sequence, and the file naming pattern. �Not all image sequences are named the same way. �For example, Movie_0001.JPG is different from Movie_1.JPG. �Once you enter the correct filename pattern, click Import Image Sequence.

Drag and Drop Image Sequences

The easiest way to import an image sequence, is to drag and drop just a single image from the sequence into the “Project Files”, or use the Import Files screen and import just a single image. �It will then prompt you to import the entire image sequence. �Using this method will automatically determine the file name pattern, and set all the correct settings for the sequence.

Add to Timeline

Drop your new image sequence on the timeline. �It is represented by a single clip, just like a regular video clip.

Create an Image Sequence

If you do not already have an image sequence, it is easy to create once. �Just right-click on any video file in your Project Files and choose Convert to Image Sequence. �It will create a new folder, and export every frame as a .PNG image file. �It will also add a reference to your new image sequence in the Project Files section automatically.

Edit an Image Sequence

If you want to edit a sequence of images, we recommend using The Gimp (an open-source image editor). �It has plug-ins to assist in editing large sequences of images, and can simplify the process of editing, saving, and opening the next image in a sequence. �You can then touch up each frame, remove red-eye, add glowing effects to light sabers, erase wires, etc... �There is really nothing you can not do with a frame by frame editing approach, but it does take a lot of effort.

Gimp Animation Package (GAP)

GAP is a plug-in for The Gimp, which assists in editing image sequences. �It can quickly save the current image and load the next image in a sequence. �It can also use key-frames to apply effects across many frames, or even create animations. �If you need to edit an image sequence, you should definitely take a look at GAP.
