Smart Erase type descriptions

Smart Erase removes and fills areas in a video that contain elements such as captions and icons. The Smart Erase feature of video-on-demand (VOD) media processing supports the following two removal types:

Smart Erase Type	Description
Caption Removal	Intelligently detects captions in a video, removes them, and fills the background. This restores the original video without captions to assist with post-production and caption regeneration. Caption removal is available in Normal (default) and Premium versions. The Premium version uses a superior algorithm for a better removal effect. However, it processes more slowly and costs more than the Normal (default) version. Choose the version that best suits your business scenario.
Icon Removal	Intelligently detects icons in a video, such as TV station logos and internet platform logos, using a built-in icon library. It removes the icons and fills the background. This restores the original video without icons to assist with post-production and reuse.

Note

The Smart Erase feature supports only MP4 videos.
