The statistics window can be displayed by clicking the icon in the bottom right hand corner as shown below
This window displays real time statistics of each live input including dropped frames and audio sync.
Each column is described in detail below:
This shows the number of dropped frames as a result of the capture card / camera running slowly.
For example, the camera clock might be slower than vMix or the capture card is experiencing a bandwidth bottleneck.
This shows the number of dropped frames as a result of the graphics card running slowly.
This number shows the number of dropped frames as a result of the capture card / camera running too fast.
For example, the camera clock might be running slightly faster than vMix.
This column shows timing statistics relating to the arrival time of each frame from the source.
Example: 33 33 33 33 (49)
In the above example, the four previous frames arrived 33 milliseconds after each other (indicating approx. 30 fps)
The number in brackets shows how long it took for the frame to be displayed on screen. (1.5 frames in this case)
These numbers will coincide with the results seen in the other dropped columns.
If a 30p camera shows 38 38 38 38 consistently, this indicates that it is running slow.
This will show up in the Source Dropped column.
If a 30p camera shows 25 25 25 25 consistently, this indicates that is running fast.
This will show up in the Resync column.
This column shows timing statistics relating to the arrival time of each sample of audio from the source.
Example: 60/67 ms Dropped: 2/0 Resampled: 0/40
These values show the fullness of the audio buffer.
Number of dropped audio samples read/write.
Number of milliseconds of audio that has been resampled to stay in sync.
