Handling Encoder Errors
Windows
Encoder errors typically occur due to conflicts between PRISM's complex features and your system's hardware, drivers, or invalid stream settings. This guide explains how to identify these alerts and resolve them to ensure a stable broadcasting environment.
1. Format Compatibility Errors
Message: "Cannot perform 10-bit encode on this encoder."
Cause: The H.264 encoder does not support 10-bit color formats.
Solution 1 (Switch to 8-bit): Go to Settings > Advanced > Video and change the Color Format to 8-bit option.
Solution 2 (Change Encoder): If 10-bit is required, go to Settings > Output and change the Video Encoder to NVIDIA NVENC HEVC.
Message: "PRISM does not support 8-bit output of Rec. 2100."
Cause: The HDR (Rec. 2100) color space is incompatible with 8-bit output.
Solution: Go to Settings > Advanced > Video and change the Color Format to P010 (10-bit), or switch the Color Space to an SDR mode like Rec. 709.
Message: "NVENC does not support I010. Use P010 instead."
Cause: The NVENC encoder does not support the I010 color format.
Solution: Go to Settings > Advanced > Video and change the Color Format to P010.
Message: "PRISM does not support using x264 with high-precision color formats."
Cause: The x264 software encoder is incompatible with high-precision formats (10-bit/16-bit).
Solution: Change the color format to 8-bit or switch to a hardware encoder (NVENC, AMF, QSV) that supports high-precision encoding.
Message: "Cannot perform 10-bit encode on Intel QSV H.264 encoder"
Cause: The H.264 encoder does not support 10-bit color formats.
Solution 1 (Switch to 8-bit): Go to Settings > Advanced > Video and change the Color Format to an 8-bit option.
Solution 2 (Switch to HEVC): Go to Settings > Output and change the Video Encoder to Intel QSV HEVC to maintain high-precision encoding.
Message: "Cannot perform 10-bit encode on AMD H.264 encoder"
Cause: The H.264 encoder does not support 10-bit color formats.
Solution 1 (Switch to 8-bit): Go to Settings > Advanced > Video and change the Color Format to an 8-bit option.
Solution 2 (Switch to HEVC): Go to Settings > Output and change the Video Encoder to AMD HW HEVC.
Message: "PRISM does not support using x264 with high-precision color formats"
Message: "PRISM does not support using x264 with high-precision color formats"
Cause: The x264 encoder is incompatible with high-precision color formats in the current environment.
Solution (Switch to 8-bit): Go to Settings > Advanced > Video and change the Color Format to an 8-bit option.
2. Hardware & Driver Errors (NVENC)
Message: "NVENC Error: Unsupported device"
Cause: Your GPU does not support NVENC, or your graphics drivers are outdated.
Solution: Ensure you are using an NVIDIA GeForce GTX 600 series or higher. Update your drivers via the NVIDIA Official Website. If using multiple GPUs, ensure the correct GPU ID is assigned in the settings.
Message: "The installed NVIDIA driver does not support this NVENC version"
Cause: A compatibility mismatch between the installed driver and the current encoder version.
Solution: Completely uninstall the existing driver and reinstall the latest version from the official NVIDIA website.
3. Resource & Session Errors
Message: "NVENC Error: Too many concurrent sessions"
Cause: The GPU has reached its limit for simultaneous encoding sessions, often due to other background apps.
Solution: Close other applications that may be using the encoder (e.g., NVIDIA ShadowPlay, Windows Game DVR). If VRAM is low, restart your PC to reset system resources.
4.Still having issues?
Because encoder compatibility depends heavily on specific hardware drivers and system environments, the solutions provided above may not cover every unique scenario. If the error persists after following this guide, our development team must analyze the cause on a case-by-case basis.
