Answer:
DVDFab and UniFab are two different products designed for different use cases, and therefore they work independently with separate licenses.
DVDFab is mainly designed for disc-based sources, such as DVDs, Blu-ray discs, ISO files, and disc folder structures. Its core functions focus on disc reading, decryption, copying, ripping, and converting content from physical media. The DVDFab All-in-One license covers these disc-related workflows.
UniFab, on the other hand, is designed for video file–based sources, such as MP4, MKV, AVI, and other common video formats. It focuses on AI-powered video processing, including AI upscaling (e.g. HD to 4K), noise reduction, deinterlacing, and overall video quality enhancement. UniFab does not directly process discs or ISO structures.
Because of this distinction:
If your source is a disc or ISO, and you need to extract or convert it into a video file first, DVDFab is the appropriate tool.
If you already have video files and want to further enhance them using AI features such as 4K upscaling, UniFab is required.
This is why, when you attempted UHD / 4K-related AI processing, DVDFab prompted you to use UniFab — the AI video enhancement features are part of the UniFab product line and are not included in the DVDFab All-in-One license.
Regarding pricing and purchase decisions: you did not make a mistake. A common workflow for many users is:
Use DVDFab to rip or convert content from discs into video files;
Then use UniFab to apply AI-based video enhancement to those files if higher quality is desired.
The two products are complementary rather than overlapping, but they do require separate licenses for their respective functions.
