Steps to Convert PPT to Video using C#

1. Set the IDE to use Aspose.Slides for .NET to convert PPT to MP4
2. Import the library classes and modules, and load the license
3. Define the input presentation and folder for the scanned images
4. Load the source presentation and iterate through all the slides in it
5. Save each slide in order as a PNG image in the images folder
6. Create the FFmpeg argument string for reading the ordered PNG sequence and encoding it
7. Launch FFmpeg and wait until the MP4 video is generated

These steps describe how to convert PPT to MP4 using C#. Import the library modules and classes, create a folder for saving the rendered images, load the presentation, and access the collection of slides. Iterate through all the slides, render each slide in order as a PNG image and save in the images folder, create the FFmpeg argument string, and start FFmpeg to create the output MP4 using the input images folder.
