Render PowerPoint slides to video frames and assemble them into a video file using Java code

Convert PowerPoint to video using Aspose.Slides

Aspose.Slides for Java can render PowerPoint presentations to image frames. To create a video, render frames with PresentationAnimationsGenerator and PresentationPlayer, then pass those frames to ffmpeg.

This PPT to video workflow uses Aspose.Slides to generate presentation frames and the Java ffmpeg wrapper to assemble the frames into a video file.
