# How To Use ViPPET The [gvapython modules article](./how-to-guides/use-gvapython-scripts.md) explains how to add user-defined Python scripts that can be loaded as modules by the `gvapython` element. The [video generator article](./how-to-guides/use-video-generator.md) explains how to use the video generator to create composite videos from images stored in subdirectories. The [pipeline configuration article](./how-to-guides/configure-pipelines.md) explains step-by-step how to configure and test AI pipelines using ViPPET's Pipeline Builder, from creating a new pipeline, editing the pipeline elements, to demonstrating running pipelines on both CPU and GPU to compare performance. The [performance testing article](./how-to-guides/performance-testing.md) covers performance testing of single pipelines as well as multiple pipelines running concurrently. :::{toctree} :maxdepth: 2 :hidden: ./how-to-guides/use-gvapython-scripts ./how-to-guides/use-video-generator ./how-to-guides/configure-pipelines ./how-to-guides/performance-testing :::
