Command Line Arguments for Rendering Movies

-MovieSceneCaptureType="/Script/MovieSceneCapture.AutomatedLevelSequenceCapture"

Used to define many of the command line arguments listed on this page.

-LevelSequence="/Game/PathToSequence/SequenceName"

Tells the Editor which sequence to play.

-NoLoadingScreen

The game instance of the Editor will fail to render properly without this.

-ResX=####

Set horizontal resolution for the game window.

Eg: -ResX=1920

Lower res for previews, Higher for final.

-ResY=####

Set vertical resolution for the game window.

Eg: -ResY=1080

Lower res for previews, Higher for final.

-ForceRes

Forces the window to the specified resolution, even when larger than the screen resolution.

-VSync

Activate the VSYNC via command line.

High Perf cost, but doesn't hurt us since we aren't rendering in real-time.

Final Renders.

-NoVSync

Deactivate the VSYNC via command line.

See the "Notes" entry in the -VSync row (located above this cell).

Preview Renders.

-MovieFrameRate=30

Sets the frame rate of the output.

Overrides the default of 30fps.

Depends on the needs of your cinematic (for example: rhythmic movement suffers when using a low FPS. This could be unwanted even in Previews).

-NoTextureStreaming

Disables texture streaming.

Will take longer to render, but worth it for final renders.

Final Renders.

-MovieFolder="PATH"

Destination folder for rendered images.

Defaults to Project/Saved/Screenshots.

Recommended when batch rendering. Otherwise all image files dump into the same folder.

-MovieFormat=ASD

Media format. JPG, BMP, PNG, or Video.

Defaults to PNG.

-MovieQuality=##

Sets the compression quality.

Expressed in a percentage, defaults to 75.

-MovieName="Example.{frame}"

Sets the naming format for the output files.

Definitely recommended for batch rendering. Gives the files a unique name corresponding to the map name, render pass, etc.

-MovieCinematicMode=Yes/No

Enables Cinematic Mode.

Hides Player Character and disables Player Character Movement. Also disables the HUD.

Usually a good idea to enable this all the time.

-MovieWarmUpFrames=##

Number of frames to run the scene before playing the sequence. This will not play out in real-time.

Default of 0 frames. This will also run the frames before the beginning of your sequence's play range.

Useful when you have Particle Systems or physics that need to simulate before you begin recording.

-MovieDelayBeforeWarmUp=#

Number of seconds before the Warm-up Begins. Runs in real-time.

If you need to do anything with your Pawn before the sequence starts.

-MovieStartFrame=###

Overrides the start frame of your sequence.

Defaults to the in and out markers in Sequencer.

-MovieEndFrame=###

Overrides the end frame of your sequence.

Defaults to the in and out markers in Sequencer.

-NoScreenMessages

Hides on-screen messages like "Rebuild Lighting" or "Print String" outputs.

-CustomRenderPasses="RenderPassName"

Sets the custom render Pass.

Options are (exclude parenthesis): AmbientOcclusion, BaseColor, CustomDepth, CustomDepthWorldUnits, CustomStencil, FinalImage, MaterialAO (Ambient Occlusion), Metallic, Opacity, PostTonemapHDRColor, Roughness, SceneColor, SceneDepth, SceneDepthWorldUnits, SeparateTranslucencyA (Alpha), SeparateTranslucencyRGB, ShadingModel, Specular, SubsurfaceColor, WorldNormal.

-CaptureFramesInHDR

Renders with HDR in the .exr format.

-HDRCompressionQuality=##

Compression Quality for HDR Frames (0 for no compression, 1 for default compression which can be slow). This is dependent on -CaptureFramesInHDR.

-CaptureGamut="HCGM_Name"

The color gamut to use when storing HDR captured data. This is dependent on -CaptureFramesInHDR.

(See Capture Gamut Descriptions below) HCGM_Rec709, HCGM_P3DCI, HCGM_Rec2020, HCGM_ACES, HCGM_ACEScg, HCGM_MAX.

-PostProcessingMaterial="MaterialPath"

The Custom Post Processing Material to use for rendering.

Format looks like: "Material'/Engine/BufferVisualization/SceneDepth.SceneDepth'" An easy way to get that path is to right-click the Material in the Content Browser and select Copy Reference.

r.ForceLOD=0

Forces all LODs to 0, whereas -1 turns it off.

r.MotionBlurQuality=4

Defines the motion blur method (adjust for quality or performance): 0 is off, 1 is low, 2 is medium, 3 is high (default), 4 is very high.

r.MotionBlurSeparable=1

Adds a second motion blur pass that smooths noise for a higher quality blur. 0 is off, 1 is on.

r.DepthOfFieldQuality=4

Allows adjusting of the Depth of Field quality. Currently only fully affects BokehDOF. GaussianDOF is either 0 for off, otherwise on.

r.HLOD=0

Single argument: 0 or 1 to Disable/Enable HLOD System. Multiple arguments: force X where X is the HLOD level that should be forced into view.

r.SSR.Quality=4

Whether to use screen space reflections and at what quality setting. Limits the setting in the post process settings which has a different scale. Costs performance, adds more visual realism but the technique has limits.

r.ViewDistanceScale=30

Controls the view distance scale. A primitive's MaxDrawDistance is scaled by this value. Higher values will increase view distance but at a performance cost.

r.MipMapLODBias=-1

Apply additional mip map bias for all 2D textures, range of -15.0 to 15.0.

r.Shadow.MaxResolution=4096

Max square dimensions (in texels) allowed for rendering shadow depths. Range 4 to hardware limit. Higher = better quality shadows but at a performance cost.
