 ## Multiframe rendering and accumulation
 
-Some rendering techniques, such as [path tracing](Ray-Tracing-Path-Tracing.md) and accumulation motion blur, combine information from multiple intermediate sub-frames to create a final "converged" frame. Each intermediate sub-frame can correspond to a slightly different point in time, effectively computing physically-based accumulation motion blur, which properly takes into account object rotations, deformations, material or lighting changes.

Each intermediate sub-frame can correspond to a slightly different point in time, effectively computing physically based accumulation motion blur, which properly takes into account object rotations, deformations, material or lighting changes.
 
 The High Definition Render Pipeline (HDRP) provides a scripting API that allows you to control the creation of sub-frames and the convergence of multi-frame rendering effects. In particular, the API allows you to control the number of intermediate sub-frames (samples) and the points in time that correspond to each one of them. Furthermore, you can use a shutter profile to control the weights of each sub-frame. A shutter profile describes how fast the physical camera opens and closes its shutter.
 
-This API is particularly useful when recording path-traced movies. Normally, when editing a Scene, the convergence of path tracing restarts every time the Scene changes, to provide artists an interactive editing workflow that allows them to quickly visualize their changes. However such behavior is not desirable during recording.

 ## API overview
 The recording API is available in HDRP and has three calls:
-- **BeginRecording**: Call this when you want to start a multi-frame render.
-- **PrepareNewSubFrame**: Call this before rendering a new subframe.
-- **EndRecording**: Call this when you want to stop the multi-frame render.
+- `BeginRecording`: Call this when you want to start a multi-frame render.
+- `PrepareNewSubFrame`: Call this before rendering a new subframe.
+- `EndRecording`: Call this when you want to stop the multi-frame render.
 
 The only call that takes any parameters is **BeginRecording**. Here is an explanation of the parameters:

 Before calling the accumulation API, the application should also set the desired Time.captureDeltaTime. The example script below demonstrates how to use these API calls.

-The following example demonstrates how to use the multi-frame rendering API in your scripts to properly record converged animation sequences with path tracing and/or accumulation motion blur. To use it, attach the script to a Camera in your Scene and, in the component's context menu, click the “Start Recording” and “Stop Recording” actions.

 You can easily define the first three profiles without using an animation curve by setting the open, close parameters to (0,1), (1,1), and (0.25, 0.75) respectively. The last profile requires the use of an animation curve.
 
-In this example, you can see that the slow open profile creates a motion trail appearance for the motion blur, which might be more desired for artists. On the other hand, the smooth open and close profile creates smoother animations than the slow open or uniform profiles.

 ## Limitations
 The multi-frame rendering API internally changes the `Time.timeScale` of the Scene. This means that:
-- You cannot have different accumulation motion blur parameters per camera.
-- Projects that already modify this parameter per frame are not be compatible with this feature.
