Demystifying Movie Render Queue

Movie Render Queue (MRQ) pluggin settings

• EXR format is a standard formar for rendering
• a 16 bit format image what stores much more data
• for color grading purposes
• Color Output tab:
• Disable Tone Curve -> true
• It ensures that the rendered image is in linear space and not a baked tone mapped image
• for color grading purposes
• Console Variables tab:
• CVARs used to fix specific issues
• Don't use any variable unless you really know what are you doing
• Game Overrides tab:
• It's used by default under the hood
• Maxes out the quality of some console variables
• Anti-aliasing tab:
• Ask yourself: "Do you want motion blur in your shot or do you want crisp sharp images without motion blur?"
• Motion Blur: Temporal Samples
• If you have some strange motion blur in physics objects or etc. you can use next fix:
• Increase the frame rate of the sequence (f.e. 48 fps instead of 24 fps) and set Motion Blur Amout to 1. It will skip every second frame but will make the motion blur smoother.
• Why it works?
• By doubling the frame rate you basically reducing the amount of motion blur in half but we bring it back by doubling the motion blur settings value to 1 (instead of 0.5 used by default).
• No Motion Blur: Spatial Samples
• + Post Process Volume (PPV) / Camera settings: Set Motion Blur Amount to 0.
• Do not mix both Temporal and Spatial, otherwise you will lose out on the benefits of temporal samples

• Sample Count works only if the Anti Aliasing Method is set to None, otherwise it'll be controlled by AA method.
• Use odd numbers for sample counts. You may not notice the difference but it's recommended way.
• There are only 2 reasons to increase the sample count:
1. To increase the motion blur quality
2. Anti-aliasing quality
• It doesn't affect the noise or flickering
• Sample Count 64-128+ is largely unnecessary unless you disabled the denoisers and really need that extra samples.
• Sample Count 15-31 is pretty enough in 95-98% of situations!
• If you need 1-8 samples, then use TSR (Temporal Super Resolution) method. It will be the fastest way to render.
• For Pathtracing it isn't unusual to need 256-1024+ samples depending on your scene.

Noise

• It is likely caused by the denoisers which can be disabled
• It's likely has more to do with the PPV settings:
• Lumen quality and distance fields
• Ray Tracing reflection samples
• Individual lights also have their own sample count

• Common Misconception: Increasing Anti-aliasing Sample Count does not reduce noise/flickering!

Post-production

• When rendering to EXR, ensure your video editing software (DaVinci Resolve, Blender, Adobe, ect) has the Color Management/Input Lookup Table set to Linear to sRGB (or Linear to Gamma 2.4 as an alternative) or else your EXR sequence will look dark, over saturated, and not what your viewport looks like.
