Adaptive field frame controls - AWS Elemental Live

Adaptive field frame controls

Description

The following are the settings and internal algorithms tied to the scan type:

  • Picture Adaptive Field Frame (PAFF): This setting is automatically enabled on GPU-enabled versions of Elemental Live and automatically disabled on CPU-only versions.

  • Macroblock Adaptive Field Frame (MBAFF): This setting is automatically enabled on CPU-only versions of Elemental Live and automatically disabled on GPU-enabled versions.

  • Force Field Pictures: This field appears only if the codec is H.264 and only affects GPU-enabled versions of Elemental Live.

    • Enabled: All outputs are forced to use PAFF field picture encoding.

    • Disabled: Elemental Live switches between PAFF and MBAFF, depending on the content.

Recommendations

  • Force Field Pictures results in a significant reduction in quality so it should only be used if required for compatibility with specific decoders or playback devices.
