How to create Slideshow and VideoConverter by FFmpeg MediaToolkit.
This is one tab on one of the my interesting program for creating slide show. In this page I describe one tabs of this program - tab fo training for processing one simple slideshow, without Polly and Pixabay. However this program can resize photo before processing, insert text (like lyrics or subtitles) and insert music. By this program you can create beautiful video from your travel, insert description for each photo and insert music to your video.
This program working on .NET interface to compiled FFMpeg to Windows - https://github.com/AydinAdn/MediaToolkit. Program working carefully, with catching error, without freezing GUI (all durable operation going in background), scale photo images to HD video, store sequence video number in registry and has many various modes to tune working. This is common view of tab I describe in this page.
And this is name of form variaables in this tab.
And this is a code of my Slideshow creator.
