Task 1: Creating animation and video clips

X1t and X2t generate plot files with the ".xtp" extension. Upon completion of a run, click the Plot Results button or double-click on any saved ".xtp" file. When Xtplot opens, configure your plot.

Go to Format → Animate to set up your animation, choose an image format (PNG, a lossless format, is a good choice) and directory, then check "Save animation to image files"

Configure your animation

Clicking the Run button will start the animation and save an image file for every step. The files will be named sequentially (Image_0001.png, Image_0002.png, …) and saved to the folder you specified.

Open VSDC Free Video Editor, a free download from Flash-Integro LLC for computers running Windows 11 or 10, and click Create slideshow


Give your project a title, specify the resolution and size if necessary (Xtplot produces 800 x 600 images by default), then click Finish to launch the File's sequence wizard

Project's settings

Left-click and hold the mouse button to drag your PNG files from your specified folder into the sequence wizard pane of VSDC. If necessary, drag slides within VSDC to reorder them

Set duration

You can create additional slides (Title, Introduction, Sections, etc.) in MS PowerPoint and save these in the same format as your image files

Drag these into VSDC as well and set their durations (you may want to set a longer duration for each descriptive slide), then hit the green checkmark to apply

Set duration

Hit Apply Settings to close the wizard and continue.
