Fields for an input prepare
This section describes how to complete the fields for these three types of input prepares:
-
A prepare of a static live input
-
A prepare of a static file input
-
A prepare of a dynamic file input
Fields for a prepare of a static live input
This table shows the fields that apply for an action to prepare a static live input.
| Field | Description |
|---|---|
| Action name | A name for this input prepare. |
| Action type | Input Prepare. |
| Input attachment | The live input to prepare. The input must already be set up as an input attachment in this channel. |
| Start type | Fixed, Immediate, or Follow. For information about start types for input prepare, see Types of starts for input prepares. |
| Date and time | If the Start type is
Fixed, specify the date and time
(in UTC format) that the channel must start to prepare the
input. This time should be at least 10 seconds before the
upcoming input switch. Note that the time is the wall clock time, not the timecode in the input. |
| Reference action name |
If the Start type is Follow, choose the input to follow. This input is the input whose end you want to use as the trigger for the input prepare. It is not the input for the upcoming input switch. The dropdown list shows all existing input switches. If the input switch that you want to use as the reference (trigger) isn't listed, you need to first create that input switch. For information about start types for input prepare, see Types of starts for input prepares. |
| Follow point | If the Start type is Follow, complete this field. The follow point is always End, to indicate that the input prepare will occur when the input in Reference action name has finished. |
Fields for a prepare of a static file input
This table shows the fields that apply for an action to prepare a static file input.
| Field | Description |
|---|---|
| Action name | A name for this input prepare. |
| Action type | Input Prepare. |
| Input attachment | The file input to prepare. The input must already be set up as an input attachment in this channel. |
| Input clippings settings – Enable input clipping | This field appears only for a file input that is eligible for input
clipping. Enable the field if the upcoming input switch (which you are preparing) will also be clipped. You must set up the prepare action with identical clipping instructions as the switch action. |
| Input clippings settings – Input timecode source |
Choose the source: Zero-based – To set the start and end times relative to the start of the file, which is 00:00:00:00. Embedded – To set the times based on the timecode in the file. The file must have a timecode, otherwise the clipping instruction is ignored. Make sure you choose the same source in this prepare action and the upcoming switch action. |
| Input clippings settings – Start timecode, Stop timecode |
Complete one or both fields. Enter values in the format hh:mm:ss:ff. Make sure you enter the same values in this prepare action and the upcoming switch action. |
| Input clippings settings – Last frame clipping behavior | This field appears only if you specify a stop timecode.
Exclude last frame – Clip the file before the frame specified in the end timecode. For example, if the end timecode is 01:00:30:19, don't include frame 19. Include last frame – Don't clip the file. In the preceding example, include frame 19. Make sure you choose the same option in this prepare action and the upcoming switch action. |
| Start type | Fixed, Immediate, or Follow. For information about start types for input prepare, see Types of starts for input prepares. |
| Date and time | If the Start type is
Fixed, specify the date and time
(in UTC format) that the channel must start to prepare this
input. This time should be at least 10 seconds before the
upcoming input switch. Note that the time is the wall clock time, not the timecode in the input. |
| Reference action name |
If the Start type is Follow, choose the input to follow. This input is the input whose end you want to use as the trigger for the input prepare. It is not the input for the upcoming input switch. The dropdown list shows all existing input switches. If the input switch that you want to use as the reference (trigger) isn't listed, you need to first create that input switch. For information about start types for input prepare, see Types of starts for input prepares. |
| Follow point | If the Start type is Follow, complete this field. The follow point is always End, to indicate that the input prepare will occur when the input in Reference action name has finished. |

| Field | Description |
|---|---|
| Action name | A name for this input prepare. |
| Action type | Input Prepare. |

| Dynamic input setting – URL path for input source A | This field appears if the input is set up as a dynamic input.
Enter a value to replace the
Make sure you enter the same values in this prepare action and the upcoming switch action. |
| Dynamic input setting – Use the same URL path for input source B | This field appears if the input is attached to a standard
channel, meaning that it has two pipelines and therefore has
two sources. Enable this field (the default) if you
want to use the same value for the
Disable this field to use a different value, then enter the value. Make sure you choose the same option in this prepare action and the upcoming switch action. |
