How to Read in a Video Nuke

Read

This node loads images from disk, using the native resolution and the frame range for the sequence. It converts all imported sequences to Nuke'southward native 32-bit linear RGB colorspace.

The Read node supports multiple file formats, such as Cineon, TIFF, Alembic, PSD, OpenEXR, HDRI, DPX, R3D, ARRIRAW, DNG, and RAW camera information. It uses the file name extension to determine the format.

Yous tin can likewise create a Read node by pressing R on the Node Graph.

See likewise DeepRead, ReadGeo, AudioRead, and UDIM Import.

Inputs and Controls

Control (UI)	Knob (Scripting)	Default Value	Role
Read Tab
File	file	dependent on file	Sets the file path and name of the file to read. For frame numbers, you can use #### for each digit or the printf-style formatting %04d.
Localization Policy	localizationPolicy	from auto-localize path	Sets the local file caching behavior. Copies of the files are stored in a specified local binder for faster access times: • on - the files are buried, regardless of location, as long as the limit to (GB) limit is non breached. • from auto-localize path - the files are cached if they reside in the motorcar-localize from directory, as long as the limit to (GB) limit is not breached. • on demand - just localize these source clips when yous manually update them. Run across Localizing Files for Better Performance for more information. • off - the files are never cached, regardless of location.
Update	updateLocalization	N/A	When this Read node is fix to Localization Policy > on demand, click Update to manually localize the files from the source files.
Format	format	dependent on file	Sets the size of the file. Typically it is guessed correctly from the file header, merely y'all can change it to set a dissimilar pixel aspect ratio if required.
Proxy	proxy	none	Sets the file path and proper noun of a relevant proxy image. This proxy image is used if proxy mode is on and the required resolution is less than or equal to the proxy format.
Proxy Format	proxy_format	1024x778	The file specified in proxy is read if the downwardly-rez of the format is smaller or equal to this value. Typically it is guessed correctly from the file header, but you can alter information technology to set up a unlike pixel aspect ratio if required.
Frame Range	commencement	dependent on file	The first frame number of a sequence to brandish.
	earlier	hold	Sets the behavior of frames earlier the first frame specified: • concord - select to evidence a notwithstanding movie of the commencement frame of the frame range. • loop - select to beginning over and go along looping the span of the frame range outside the start frame of the frame range. • bounciness - select to play the span of the frame range backwards and frontward between the frame range limits. • black - select to display a black frame outside of the offset frame.
	terminal	dependent on file	The last frame number of a sequence to display.
	after	agree	Sets the behavior of frames afterward the last frame specified: • hold - select to show a however picture of the last frame of the frame range. • loop - select to showtime over and go on looping the span of the frame range outside the last frame of the frame range. • bounce - select to play the span of the frame range backwards and forward between the frame range limits. • blackness - select to display a black frame outside of the last frame.
Frame	frame_mode	expression	Sets the frame mode: • expression - Lets you enter an expression in the field on the correct. The expression changes the relation between the current frame and the frame read in. For case, if your prune begins from image.0500.rgb and yous want to place this outset frame at frame 1 rather than frame 500, you tin can use the expression frame+499. This mode, 499 frames are added to the current frame to get the number of the frame that'southward read in. At frame 1, image.0500.rgb is read in; at frame two, image.0501.rgb is read in; and and so on. Another example of an expression is frame*2. This expression multiplies the current frame by ii to get the number of the frame that's read in. This way, only every other frame in the clip is used. At frame ane, image.0002.rgb is read in; at frame 2, image.0004.rgb is read in; at frame 3, paradigm.0006.rgb is read in; and so on. • get-go at - Lets you enter a start frame number in the field on the right. This specifies the frame where the starting time frame in the sequence is read in. In other words, all frames are offset so that the clip starts at the specified frame. For example, if your sequence begins from image.0500.rgb and you lot enter 1 in the field, image0500.rgb is read in at frame 1. Similarly, if yous enter 100 in the field, image0500.rgb is read in at frame 100. • kickoff - Lets you enter a constant offset in the field on the right. This abiding value is added to the electric current frame to go the number of the frame that'southward read in. For example, if your clip begins from image.0500.rgb and you want to place this get-go frame at frame 1 rather than frame 500, yous tin can utilize 499 as the abiding commencement. This way, 499 is added to the current frame to get the frame that'due south read in. At frame 1, prototype.0500.rgb is read in; at frame 2, image.0501 is read in, and so on. Y'all can also use negative values every bit the constant offset. For example, if you apply the value -ten, Nuke volition subtract 10 from the current frame to become the frame that's read in. At frame 20, epitome.0010.rgb is read in; at frame 21, image.0011.rgb is read in; and and so on.
	frame	none	Depending on the frame mode, you can enter a first frame, an offset, or an expression here.
Original Range	origfirst	dependent on file	Displays the original first frame.
	origlast	dependent on file	Displays the original last frame.
Missing Frames	on_error	error	Sets Nuke's beliefs when in that location is a problem with frames in the file: • error - display an error in the Viewer. • black - replace suspect frames with a black frame. • checkerboard - replace suspect frames with a checkerboard. • nearest frame - supervene upon suspect frames with the nearest expert frame.
reload	reload	North/A	Click to re-read the paradigm from disk.
Input Transform	colorspace	dependent on file	Sets the color transform used to convert this file to Nuke'due south working space. The working infinite is divers in the Preferences or Project Settings > Color Management settings. The default determines the LUT from the size and type of data in the file, and other information from the file header. Note: The command label has been updated, but the knob name currently remains the same. The knob proper name volition also alter in a hereafter release.
Premultiplied	premultiplied	disabled	When enabled, Nuke corrects the color of the partially transparent pixels produced by about renderers by dividing colour data by the alpha aqueduct before converting from the colorspace, and then multiplying by the alpha aqueduct afterwards.
Raw Data	raw	disabled	When enabled, Nuke does not convert the data. For most file formats this is the same as linear colorspace but, for some, it may disable other processing such as conversion from YUV.
Auto Alpha	auto_alpha	disabled	When enabled, if the Read produces RGB but no alpha channel, then assume the alpha should be 1 if information technology'due south requested later on.
OCIO Tab
Context
key1	key1	none	OCIO Contexts permit you lot to apply specific LUTs to individual shots. See Changing the Viewer Color Space for more data.
value1	value1	none
key2	key2	none
value2	value2	none
key3	key3	none
value3	value3	none
key4	key4	none

Sequence Tab
import sequence	import sequence	N/A	Click to display a browser to locate an import sequence script which builds a frame sequence list from the contents of an EDL file. These are not standard EDL files, such as CMX. Each line in the file merely defines a separate epitome sequence to import in the form: imagesequence.%04d.ext in out caput tail Where in and out are the start/finish frame numbers of the clip and head/tail are the number of frames to trim from the start and end. Each sequence in the list is expanded into the sequence command so that each line contains the name of the file to read for that frame: line 1 = frame 1, line 10 = frame 10. Finally, the script replaces the Read > file text with: [lindex [knob sequence] [frame]] This looks upwardly the file name from the sequence control and sets the first frame to i through to the last frame in the expanded list.
frame sequence	sequence	none	Nigh easily used in conjunction with the import sequence button. Each line contains the name of the file to read for that frame: line ane = frame 1, line 10 = frame 10. Set the Read > file control to [lindex [knob sequence] [frame]] to expect up the file name from this control. This allows you to apply a single Read to admission multiple sequences of files where the naming does non follow any set numeric sequence, rather than using multiple Read nodes with a single file sequence per Read.
Metadata Tab
metadata viewer	shownmetadata	N/A	Displays the metadata of any file read in using a Read node. One time you know which keys exist in the file, you tin reference them in expressions. The metadata displayed depends on the file blazon. For instance, a .jpg might only contain input/ keys, whereas QuickTimes incorporate input/ and quicktime/ keys.
search metadata for	metadatafilter	N/A	Filter the metadata by entering text in this field. By default, just metadata containing the keys and values entered are displayed. You can alter this beliefs using the within control.

Transcription

Nosotros have gone over the basics of the Nuke interface. We can now motion in and import some footage and create a basic network. In order to import footage into Nuke, you accept to use a Read node. There are four master ways to create a new node in Nuke. The offset is to go upwardly to the toolbar and select a node, in this instance, it will be under the first icon Image and then I can select Read. I will get out this for at present. The second manner is to return to the Node Graph, right-click, and choose a node from the list; once again Paradigm > Read. The third way is to press the Tab key on your keyboard, type the node name into the jail cell, and once yous run across the name, select it from your dropdown list. The 4th way is to use a pre-assigned hotkey, in this example, the Read node has the R cardinal, and so the R key on the keyboard.

Now, if you lot used whatever of those four methods, you will get this scan window. On the left, you lot will see all of the drives and all of the main directories. You click on a directory name 1 time to go into that directory. Once you become to a folder with footage, you will see information technology listed, in this example, I have an paradigm sequence. Nuke automatically recognizes epitome sequences, assuming that they are numbered correctly. So, hither the image sequence runs from 0-xc. You can simply click on the image sequence until it turns orangish and open up information technology. Now, if you were to open a even so paradigm, or say a QuickTime movie, you lot would see those listed likewise. You would simply click on those files until they turned orange and open those also. And then, I am going to click Open now and there is a Read node. Y'all can click+drag any of these nodes to rearrange them inside the Node Graph.

So, allow's make a unproblematic network. What I can do is connect these ii nodes together. To exercise that, I can click+drag the end of this input pipe on the Viewer, which looks similar an pointer, and then drag+drib information technology on top of Read1. Once I allow go of the mouse push, it makes a connectedness, and there you see the image sequence in the Viewer. Note the prototype sequence is 1920x1012. You volition see that on the bounding box and also information technology will appear by the format. If I disconnect this, and I tin can do that by click+dragging the finish of this pipage and letting go, I will see that the original project format is 2K. Then, keep in mind, if I reconnect this that Nuke will modify the view based on the resolution of the input going into the Viewer. Now, there are means to reformat inputs so I can change the width and height, but we'll salve that for a later video. For now, this is OK.

Let's return to the backdrop console and take a expect at the backdrop. Of course, you lot have your path and the name of your image sequence, the recognized resolution, as well the recognized frame range, and, at the very end in that location, is your colorspace. Now, colorspace is set up to default (linear). What that means is the Read node is not making whatsoever additional color changes to the image sequence. I should note, however, that Nuke operates in a 32-bit floating point colorspace. Whereas a regular eight-bit colorspace operates with two⁸ of colors per channel or 256 colors per channel, Nuke potentially operates 2³² colors per channel. As well, because its floating point ways that Nuke can operate with decimal places. In other words, you tin can have a value for a color that is something like i.000000001 - an incredibly tiny decimal place value. And then, a combination of a big bit depth and as well the ability to handle decimal places means that Nuke operates in a very large, very accurate colorspace. Nosotros have imported footage and we have created a basic network, now we are prepare to move on to more circuitous node networks.
