There are two types of Video which can be rendered by LumenRT. Following are the rendered video types in LumenRT:

Movie Options - The movie output dialog provides several options for creating videos.

SettingDescription
Resolution Select an image output size from the available resolution options.
Destination Sets where the image files are saved.
Quality

Sets the output quality to one of three possible options:

  • Fast - Rapid output with no anti-aliasing and low definition reflections and shadows suitable for draft previews.
  • Standard -Normal output with high level anti-aliasing and full reflections and shadows suitable for final presentation output.
  • Super fine - Much slower but higher quality output with extreme anti-aliasing. Use this mode only in very rare cases when the scene contains fine level details such as power lines or chain-link fencing which require greater anti-aliasing.
Video Encoder A drop-down list indicating the type of encoder desired for the video.
Frame Rate The desired number of frames per second (fps). 25 fps is common for most presentations and YouTube videos.
Format either standard video or VR 360 panoramic video.
Stereo Outputs a customizable side-by-side or top-bottom video format suitable for a variety of 3D formats.
Range If the frame option is selected, allows the specifications of either a frame range or a start and end time.

360 VR Panoramic Output

360 degree panoramic output generates spherical video suitable for playback in 360 viewers (e.g. YouTube) and phone-based headsets such as Google Cardboard, Samsung Gear VR, Occulas and HTC vive. In general, you should use the "YouTube" video encoder when creating 360 VR output since this will inject the necessary metadata into the mp4 file in order for Youtube and VR headsets to automatically recognize the 360 format. Alternatively, you can manually inject the metadata into your mp4 file by using the Google metadata injector found here.

8K UHD Output - 8K ultra high definition output is just now entering the market and as such, there are very few viewers and headsets that can handle 8K UHD output.
