Frequently Asked Questions
Does MS2131 support 4K60?
No, MS2131 supports 4K (3840x2160) at up to 30fps. For 4K60 applications, consider using a different solution or contact MacroSilicon for roadmap information. The chip can capture 1080p at 60fps, and 4K30 is the maximum for 4K resolution.
Maximum 4K30. For 4K60, contact FAE for alternative solutions.
Can it stream 1080p while recording 4K?
Yes, MS2131 features hardware scaling that can simultaneously output 4K for recording and 1080p for streaming. This is done through hardware scaler before USB output, reducing host CPU load. Both streams maintain high quality. Perfect for content creators who want 4K archives with 1080p live streams.
Use hardware scaling for dual-output applications. Reduces CPU load significantly.
