Can Render Manager Save Multiple Saver Nodes Within Same Comp?

[VFXTobias]

Subject says it all.

New to using Render Manager in Fusion 9 Studio. Just curious. Thank you for your time.

[VFXTobias]

Nevermind. The answer is yes so far. The saver nodes are at different frame lengths so I guess I'll see if the render manager stops when the shortest saver reaches its end frame.

[Midgardsormr]

If a Saver attempts to call for a frame and can't get it, then the entire render job will fail at that frame. If the Saver is disabled when it reaches the first unavailable frame, though, it will not. There is a script in VFXPedia that can be used to set render ranges for Savers, disabling them and enabling them as needed. It hasn't yet been updated for Fusion9, I don't think.

Thank you. Tried it. All I can see happening is this message in the console.

"...ing\Blackmagic Design\Fusion\Scripts\Comp\TrimSavers.lua:41: attempt to call a table value"

No other indication that anything has happened.

I don't have the time to update it myself, but if you look at the thread where I documented my update to Batch Change Parameters, you should be able to glean the information you need to get this one running.

Or you can wait for a while, and someone else may take the time to do it. Or maybe not.

You can also manually set the ranges on the Savers (just like you can for any tool).

I see the section that accepts render scripts in the node but it is not very user intuitive. Got an example of this in action I can learn from?

[Chad]

You don't need any script, just change the enabled time region of the tool.

Code: Select all

{
	Tools = ordered() {
		Triangle1 = TriangleMask {
			CtrlWZoom = false,
			Inputs = {
				MaskWidth = Input { Value = 1920, },
				MaskHeight = Input { Value = 1080, },
				PixelAspect = Input { Value = { 1, 1 }, },
				ClippingMode = Input { Value = FuID { "None" }, },
				Point1 = Input {
					SourceOp = "Perturb1",
					Source = "Value",
				},
				Point2 = Input {
					SourceOp = "Perturb2",
					Source = "Value",
				},
				Point3 = Input {
					SourceOp = "Perturb3",
					Source = "Value",
				},
			},
			ViewInfo = OperatorInfo { Pos = { 330, 214.5 } },
		},
		Perturb1 = PerturbPoint {
			CtrlWZoom = false,
			Inputs = {
				Value = Input { Value = { 0.1, 0.1 }, },
				RandomSeed = Input { Value = 16945, },
			},
		},
		Perturb2 = PerturbPoint {
			CtrlWZoom = false,
			Inputs = {
				Value = Input { Value = { 0.9, 0.1 }, },
				RandomSeed = Input { Value = 20653, },
			},
		},
		Perturb3 = PerturbPoint {
			CtrlWZoom = false,
			Inputs = {
				Value = Input { Value = { 0.5, 0.9 }, },
				RandomSeed = Input { Value = 5481, },
			},
		},
		Saver1 = Saver {
			CtrlWZoom = false,
			EnabledRegion = TimeRegion { { Start = 30, End = 70.9999, FrameLength = 1 } },
			Inputs = {
				ProcessWhenBlendIs00 = Input { Value = 0, },
				Clip = Input {
					Value = Clip {
						Filename = "Temp:\\Deleteme_.raw",
						FormatID = "RawFormat",
						Length = 0,
						Saving = true,
						TrimIn = 0,
						ExtendFirst = 0,
						ExtendLast = 0,
						Loop = 1,
						AspectMode = 0,
						Depth = 0,
						GlobalStart = -2000000000,
						GlobalEnd = 0
					},
				},
				CreateDir = Input { Value = 1, },
				OutputFormat = Input { Value = FuID { "RawFormat" }, },
				["Gamut.SLogVersion"] = Input { Value = FuID { "SLog2" }, },
				Input = Input {
					SourceOp = "Triangle1",
					Source = "Mask",
				},
			},
			ViewInfo = OperatorInfo { Pos = { 440, 214.5 } },
		}
	}
}

I didn't realize that worked for tools that didn't have the Global range control in the control panel. That's set just by dragging the in/out points in the Timeline View?

[Chad]

Yeah, or with script. But you can just drag it in the timeline view for one-offs.

The downside is you have only one range. Can't do 10-25, 30-50. That's where you need a script (or two SVs).

Oh, another option is to animate the Blend of the SV to zero. It won't write frames when it's set as such. So you could animate that quickly to set an oddball frame set. Again, quick and dirty, not for pipeline use.

EDIT: And THIS is one of the top reasons I shake my head when people say "just put Fusion inside Resolve". If the Fusion Connect function in Resolve was updated to make one comp with multiple Savers which had their ranges and frame offsets set, heads might explode.

[guacamole]

This is a great tip thanks. However how could one pass a variable such as an user added control to input the range in the gui.

Doesn't seem to like anything but an integer there. Does not like this;

or this

Code: [Select all] [Expand/Collapse] [Download] (Untitled.lua)

1. EnabledRegion = TimeRegion { { Start = Input {Value = 0, Expression = "renderRageStart", }, End = {Value = 1000, Expression = "renderRageStart", }, FrameLength = 1 } },

[guacamole]

A conditional statement on the blend could also work, fine for one condition like this iif(time > renderRangeEnd, 0, 1) however what would be the syntax for extra conditions in an expression such as : iif(time < renderRangeStart && time > renderRangeEnd, 0, 1) ?

cheers

[AndrewHazelden]

@guacamole You could nest the 2nd parameter inside the true result of the first parameter in an iff(). Or, sometimes it's simply easier to place a colon : symbol at the start of an expression field and then unlock the full capacity of Lua inline scripting in the expressions field text area.

[guacamole]

Thank you @AndrewHazelden. I did try the : block first without success. Would you expect this to work
Blend = Input { Expression = ":if time <= renderFrameStart then return 0; else if time => renderFrmeEnd then return 0; else return 1; end", },

[AndrewHazelden]

what would be the syntax for extra conditions in an expression

The early KartaVR "SetMetadataVR" macro node used a deeply nested set of iif's to switch between the items in a combo control to define the value pushed into a SetMetadata node. (Later on I switched the macro over to be a fuse).

Code: Select all

iif(SetMetadataVR.Projection == 0, "", iif(SetMetadataVR.Projection == 1, "{Format = \"LatLong\"}", iif(SetMetadataVR.Projection == 2, "{Format = \"VCross\"}", iif(SetMetadataVR.Projection == 3, "{Format = \"HCross\"}", iif(SetMetadataVR.Projection == 4, "{Format = \"VStrip\"}", iif(SetMetadataVR.Projection == 5, "{Format = \"HStrip\"}", ""))))))

Edit:
Slightly unrelated to your current needs but useful to you down the road... as expression scripting tricks go, PeterLoveday did a neat WSL post where he helped Kristof with a coding tip. He showed that one could use the value from a User Control element (like a ComboControl) directly to select an array indice from a Lua table. I think it related to using the select() Lua command to extract a "value pack" as part of an expression and return it as a text string. That was some fancy expression coding.
