Video rendering

OpenEmulator features GPU accelerated advanced video rendering. Legacy hardware and virtual monitors are separated by using actual emulated video signals. Many kinds of monitors can be emulated by combining the following features:

• Standard monitor controls: brightness, contrast, saturation, hue
• Active video center/size controls
• Monitor shadow masks: triad, in-line, aperture grille, LCD, Bayer
• CRT barrel effect
• CRT dynamic scanline effect
• CRT phosphor persistence
• CRT center lighting
• Video bandwidth controls
• Composite TV IRE levels
• Composite TV luma and chroma bandwidth
• Composite TV per-line variable color burst
• Composite TV per-line U phase alternation
• Composite TV Y'UV, Y'IQ (with standard I and Q bandwidth) and Sony decoders

Here you can see the canvas controls of an emulated studio monitor:

And the decoded image (notice the cross luma/chroma artifacts resulting from old chroma decoding techniques):
