Record

If you experience issues with the recording results (e.g. lost frames, low resolution etc) you can press the red i in the bottom menu bar.



This icon is only available during recording. You have performance issues if you experience dropped frames due to hard disk / CPU.



By default we setup recording in 1920x1080 in 8Mbps MP4 format. You can check these settings only when you are not recording.

Press the settings icon in the bottom menu bar to check the settings.



If the option to change the Output Size isn't available; disable the "Use Streaming Settings" checkbox.



TIP: On older hardware without a separate graphics card you might want to disable Use Hardware Encoder since the available GPU might not be powerful enough.


Render time


The "Render Time" display at the bottom of vMix indicates how much of your computers' graphics cards time is being used to render each frame of your production.

It is displayed in milliseconds, so if your production is 25 frames per second (approx 40ms per frame), a render time of greater than 40ms this will result in dropped frames.


NOTE: A teamviewer remote session increases the load on the GPU and might result in too high render times.

Stream

If you experience issues with the stream (e.g. lost frames, low resolution etc) you can press the red i in the bottom menu bar next to External.



This icon is only available while streaming. You have performance issues if you experience dropped frames due to hard disk / CPU.



By default the output resolution to the stream is set via External.



By default we setup the profile to use 1920x1080 with 25 fps. This is used as input for the streaming profile you have selected in the Controller settings.



You can experience issues in the following cases

  • External output size is lower than the selected stream profile (upscaling)
  • There is not enough CPU/GPU to render the selected stream.


e.g.  In the following stream profile both 1280x720 and 1920x1080 will be created.

If the external output is set to 640x360 it will try to create both streams and will need a lot of CPU/GPU.
