NOTES:
-
Content is played back at 30 fps and 60 fps as outlined in the video codec above.
-
All HD codecs listed above have an output resolution relevant to Full-HD (1920 x 1080).
-
All UHD codecs listed above have an output resolution relevant to 4K DCI (4096 x 2160).
-
One codec and frame rate tested per track.
-
One unique video file per layer.
-
One LED screen per resolution tested (Full-HD and DCI 4k)
-
The test machine is run as an actor with its GUI disabled.
-
Absolute maximum level of performance. One more layer means that the system will start to drop frames.
-
Measured against r21, build 87976.
Capture Latency
The following table provides data on how many frames of latency the gx 2c requires from capture to output:
gx 2c + SDI
| Refresh Rate | Normal mode (frames) | Low Latency mode (frames) | Ultra-Low Latency (frames) |
|---|---|---|---|
| 60Hz | 5 | 4 | 3 |
| 50Hz | 5 | 4 | 3 |
| 30Hz | 5 | 4 | 3 |
