vx 2 Performance
Playback [confirm latency tables- SDI or NDI?]
Performance specifications listed here outline the maximum amount of video layers that are achievable on a single vx 2. These can fluctuate in future releases.
Benchmarks - Video Layers (Full HD)
| Video Codec | Content Data Rate (MB/s) | Max Layers on vx 2 |
|---|---|---|
| HAP 30 | 29.54 | 60 |
| HAPQ 30 | 58.43 | 38 |
| Animation 30 | 178.63 | 13 |
| NotchLC 30 | 74.74 | 29 |
Benchmarks - Video Layers (4k DCI)
| Video Codec | Content Data Rate (MB/s) | Max Layers on vx 2 |
|---|---|---|
| HAP 30 | 125.93 | 21 |
| HAPQ 30 | 249.23 | 10 |
| Animation 30 | 761.27 | 3 |
| NotchLC 30 | 316.34 | 8 |
| DPX Sequence, 8-bit, RGB, 30 | 759 | 3 |
| DPX Sequence, 8-bit, RGB, 60 | 1518 | 1 |
NOTES:
-
All content is 30 fps, with the exception of DPX Sequence, 8-bit, RGB, 60.
-
Readings are taken from an actor machine.
-
VFC-compatible machines run with pass-through style cards (HDMI or DP).
-
60Hz project.
-
Genlock/framelock applied when supported.
-
One unique video file per layer, all mapped onto one screen.
-
All videos used are the same video of the specified data rate.
-
One more layer means the actor starts to drop frames.
-
Measured on r17.5, Build 74443.
Capture Latency
The following table provides data on how many frames of latency the VX 2+ requires from capture to output:
vx 2 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 |
