Q1: What is the multi-channel encoding capability of Director Plus?

A: Director Plus allows you to configure multiple encoding schemes with different resolutions, frame rates, and bitrates. All encoding schemes can be flexibly assigned to live streaming, recording, and replay. The same encoding scheme can be used simultaneously for streaming, recording, and replay without consuming additional encoding resources. Lower resolutions and frame rates require fewer encoding resources, allowing more concurrent encoding tasks.

Q2: How does enabling NDI streaming affect the encoding capability for other services?

A: NDI streaming uses dedicated encoding schemes. When NDI streaming is enabled, the encoding resources available for live streaming, recording, and replay will be reduced accordingly. 

Q3: What are the typical encoding combinations for different show quality levels?

A: Director Plus supports three show quality levels: 2160p (4K), 1440p, and 1080p. Typical encoding combinations for each show quality level are shown below. A maximum of 12 encoding tasks can run concurrently (4 streams, 4 recordings, 4 replays).

Note: The combinations below assume ideal operating conditions. Actual performance may vary depending on system load and operating conditions.

Q4: How are encoding resources consumed at different resolutions and frame rates?

A: Different encoding schemes have approximately equivalent resource requirements as shown below. You can refer to these equivalencies to estimate how many encoding tasks can run concurrently. Note that resource consumption relationships are approximate; actual limits are determined by the system.

• 1 x 4K60 ≈ 2 x 4K30
• 1 x 4K60 ≈ 4 x 1080p60
• 1 x 4K30 ≈ 2 x 1080p60
• 1 x 1440p60 ≈ 2 x 1440p30
• 1 x 1440p60 ≈ 4 x 720p60
• 1 x 1440p30 ≈ 2 x 720p60
• 1 x 1080p60 ≈ 2 x 1080p30
• 1 x 1080p60 ≈ 2 x 540p60
• 1 x 1080p30 ≈ 1 x 540p60

Q5: How to select encoding combinations based on your production requirements?

A: Lower resolutions and frame rates require fewer encoding resources, allowing more concurrent encoding tasks. Refer to the typical configurations and approximate resource equivalencies above to plan your encoding schemes and achieve the best balance between show quality and the number of concurrent encoding tasks.
