Creating animation and video clips is part of a free web series, GWB Online Academy, by Aqueous Solutions LLC.
What you need:
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"
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 10, 8.1, 8, or 7, 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
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
Select all frames and set the duration (in milliseconds) for each, then hit the green checkmark to apply
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
Hit Apply Settings to close the wizard and continue.
Move to the Export project tab
Save to PC, choose a video format, set the name and location of the video to be generated, then click Export project
If you're using the free version of VSDC, hit continue to finish
To avoid this message with the free version of VSDC, go to Options → Accelerator Options and uncheck “Use hardware acceleration for encoding video”
VSDC will assemble the slides together and save them as a video clip. Click the Play button to view your movie
