renderqueueitem

RenderQueueItem object

app.project.renderQueue.item(index)

Description

The RenderQueueItem object represents an individual item in the render queue. It provides access to the specific settings for an item to be rendered. Create the object by adding a composition to the Render Queue with the RQItemCollection object; see RQItemCollection.add().

Attributes

RenderQueueItem.comp

app.project.renderQueue.item(index).comp

Description

The composition that will be rendered by this render-queue item. To change the composition, you must delete this render-queue item and create a new one.

Type

CompItem object; read-only.

RenderQueueItem.elapsedSeconds

app.project.renderQueue.item(index).elapsedSeconds

Description

The number of seconds spent rendering this item.

Type

Integer, or null if item has not been rendered; read-only.

RenderQueueItem.logType

app.project.renderQueue.item(index).logType

Description

A log type for this item, indicating which events should be logged while this item is being rendered.

Type

A LogType enumerated value; (read/write). One of:

  • LogType.ERRORS_ONLY
  • LogType.ERRORS_AND_SETTINGS
  • LogType.ERRORS_AND_PER_FRAME_INFO

RenderQueueItem.numOutputModules

app.project.renderQueue.item(index).numOutputModules

Description

The total number of Output Modules assigned to this item.

Type

Integer; read-only.

RenderQueueItem.onstatus

app.project.renderQueue.item(index).onstatus

Description

The name of a callback function that is called whenever the value of the RenderQueueItem.status attribute changes.

You cannot make changes to render queue items or to the application while rendering is in progress or paused; you can, however, use this callback to pause or stop the rendering process. See RenderQueue.pauseRendering() and RenderQueue.stopRendering(). See also app.onError.

Type

A function name string, or null if no function is assigned.

Example

function myStatusChanged() {
    alert(app.project.renderQueue.item(1).status);
}


app.project.renderQueue.item(1).onstatus = myStatusChanged();
app.project.renderQueue.item(1).render = false; // changes status and shows dialog

RenderQueueItem.outputModules

app.project.renderQueue.item(index).outputModules

Description

The collection of Output Modules for the item.

Type

OMCollection object; read-only.

RenderQueueItem.queueItemNotify

app.project.renderQueue.item(index).queueItemNotify

Description

Scripts can read and write the Notify checkbox for each individual item in the Render Queue. This is exposed in the UI as a checkbox next to each Render Queue item in the Notify column.

This column is hidden by default and may need to be selected to be visible by right clicking on the Render Queue column headers and choosing Notify.

Type

Boolean; read/write.

RenderQueueItem.render

app.project.renderQueue.item(index).render

Description

When true, the item will be rendered when the render queue is started. When set to true, the RenderQueueItem.status is set to RQItemStatus.QUEUED. When set to false, status is set to RQItemStatus.UNQUEUED.

Type

Boolean; read/write.

RenderQueueItem.skipFrames

app.project.renderQueue.item(index).skipFrames

Description

The number of frames to skip when rendering this item. Use this to do rendering tests that are faster than a full render. A value of 0 skip no frames, and results in regular rendering of all frames. A value of 1 skips every other frame. This is equivalent to “rendering on twos.” Higher values skip a larger number of frames. The total length of time remains unchanged. For example, if skip has a value of 1, a sequence output would have half the number of frames and in movie output, each frame would be double the duration.

Type

Integer, in the range [0..99]; read/write.

RenderQueueItem.startTime

app.project.renderQueue.item(index).startTime

Description

The day and time that this item started rendering.

Type

Date object, or null if the item has not started rendering; read-only.

RenderQueueItem.status

app.project.renderQueue.item(index).status

Description

The current render status of the item.

Type

An RQItemStatus enumerated value; read-only. One of:

  • RQItemStatus.WILL_CONTINUE: Rendering process has been paused.
  • RQItemStatus.NEEDS_OUTPUT: Item lacks a valid output path.
  • RQItemStatus.UNQUEUED: Item is listed in the Render Queue panel but composition is not ready to render.
  • RQItemStatus.QUEUED: Composition is ready to render.
  • RQItemStatus.RENDERING: Composition is rendering
  • RQItemStatus.USER_STOPPED: Rendering process was stopped by user or script.
  • RQItemStatus.ERR_STOPPED: Rendering process was stopped due to an error.
  • RQItemStatus.DONE: Rendering process for the item is complete.

RenderQueueItem.templates

app.project.renderQueue.item(index).templates

Description

The names of all Render Settings templates available for the item. See also RenderQueueItem.saveAsTemplate().

Type

Array of strings; read-only.

RenderQueueItem.timeSpanDuration

app.project.renderQueue.item(index).timeSpanDuration

Description

The duration in seconds of the composition to be rendered. The duration is determined by subtracting the start time from the end time. Setting this value is the same as setting a custom end time in the Render Settings dialog box.

Type

Floating-point value; read/write.

RenderQueueItem.timeSpanStart

app.project.renderQueue.item(index).timeSpanStart

Description

The time in the composition, in seconds, at which rendering will begin. Setting this value is the same as setting a custom start time in the Render Settings dialog box.

Type

Floating-point value; read/write.
