UP.Capture Channels

UP.Capture captures live video from IP-based sources. You create a channel for each source you want to record, configure how that channel records, then start captures manually or let them run automatically via schedules or triggers. This page covers the full lifecycle of a channel, in the order you’ll work through it.

​

Concepts

Understanding four terms makes the rest of this page easier to follow.

​

Where recordings go

Recordings will end up in the S3 bucket associated in the recording configuration. Each channel can record in a different storage location, so users can, for example, define different locations for proxy and hi-res recording.

​

Before you begin

• At least one live source must be configured. See Configuring Live Sources.
• User must have correct access rights to configure/setup a recording channel.

​

Workflow

1. Add a channel — bind a live source to a new channel.
2. Configure the recording — set format, naming and destination.
3. Capture video — activate the channel, then start and stop recording.
4. Monitor channels — check previews, transport statistics, and metadata.
5. Review recording history — confirm what was captured.

​

Add a channel

The Add New Channel panel is a three-step wizard: General Info, Stream Settings, and Payload.

1. In the UP left-side navigation bar, under Capture, select Channels. UP.Capture opens the channels preview panel.
2. Click Add New Channel.
3. Select the source type from the drop-down menu. UP.Capture opens the Add New Channel panel on the right.
4. Complete the General Info step, then click Next.

   Field	Description	Required
   Channel Name	Name of the channel	Y
   Description	Add additional information to the channel card	N
   Tags	Add multiple tags for easy search and filtering	N
   SCTE35 recording triggers	Configures how the channel reacts to incoming SCTE-35 signals. Not yet acted on — see Automated capture	N
   Automatic Channel Shutdown	Configures the idle threshold after which the channel deactivates its own worker	N

5. In the Stream Settings step, select a source from the Live Source drop-down menu, then click Next. Only sources already configured in UP appear here. If your source is missing, see Configuring Live Sources. Each source carries a coloured dot showing whether it is ready to be recorded. See Live Source indicators.
6. Complete the Payload step, then click Next.

   Field	Description	Required
   Output template	Available output templates can be selected, if none are stored, saving the channel will take the user directly to the configuration page	Y
   Input resolution	Define the expected input resolution coming from the live source	Y
   Input frame rate	Define the expected input frame rate coming from the live source	Y
   Time Code source	Select between Source, Computer Clock or None	Y
   LOS Video Test Pattern	Define which pattern will be inserted in case of signal loss from the live source. Choose between 75% or 100% colour bars and eight solid mattes	Y

The new channel appears as a card in the channels preview panel. When you edit an existing channel, the three steps become clickable chips, so you can jump straight to the one you need instead of stepping through all three.

Configure a recording

Each channel carries its own recording configuration — the format, location, and naming rules applied every time that channel captures.

1. In the UP left-side navigation bar, under Capture, select Channels.
2. On the channel card, click Edit Recording Configuration. UP.Capture displays the Configurations pane in the Configure Recording view.
3. Either add a new configuration with the + button, or modify an existing configuration.
4. Click the Edit (pencil) button.
5. Change the settings as needed.

   Setting	Description	Default
   Container Format	Choose recording container format (MXF OP-1a, MXF XAVC, QuickTime)	MXF OP-1a
   Output Location	Select S3 bucket to store output recordings	-
   File Name	Configure file name pattern for output recordings	Date(MM-DD-YYYY)_ChannelName

6. Click Save Configuration.

The default file name is built from tokens rather than literal text: a date token and a channel-name token. Edit or replace them to change the pattern.

​

Capture video

Capturing is a two-stage operation: you activate the channel to reserve a worker, then start the recording.

​

Activate the channel

1. In the UP left-side navigation bar, under Capture, select Channels.
2. On the channel card, click the Activate button. UP.Capture assigns a worker, sets the Channel Status to Ready To Record, starts the worker uptime timer, and opens the Channels Display and Information Panel with Preview selected. For control descriptions, see UP.Capture Windows, Controls, and Menus.

Confirm the preview shows live video before recording. A channel can be Ready To Record while nothing is arriving on its source — check that its Stream Status reads Connected. If it does not, see Loss of signal.

​

Start and stop recording

1. Click the Start/Record button. The Channel Status changes to Starting Recording, then to Recording once output is being written, and the button becomes Stop.
2. To finish, click Stop.
3. Click Stop Recording to confirm. The Channel Status changes to Finishing Recording while the output files are finalized, then back to Ready To Record.

If a recording cannot start, UP.Capture reports the reason rather than creating a job: the source is disabled, the source could not be found, the source stream is unavailable, the source is in an outage, or the source could not be reached in time. Recording can only be started from the Ready To Record status — for the full list, see Channel Status values.

​

Abort a recording

While a recording is finalizing its output files — Channel Status Finishing Recording — the recording button becomes an Abort button.

​

Automated capture

Captures can also run without an operator, via event schedules, triggers, or gang recording.

​

Monitor a channel

​

Preview

1. In the UP left-side navigation bar, under Capture, select Channels.
2. Click the channel card for the source you want to inspect.
3. Click the More options icon (⋮) in the upper-right corner.
4. Select “Open Preview”.
5. The right-side panel opens with the preview pane open.

Clicking a card’s thumbnail opens the same panel directly. The preview pane is showing you the live video of the live source attached to the channel as well as the current audio configuration. To listen into a specific audio track, click the ‘S’ button next to the respective audio channel. To listen to the full mix, click the ‘S’ button next to the # symbol. Tracks can also be muted individually. The two collapsable menus below list the number of existing audio and text tracks as well as their properties.

​

Transport Statistics

Transport statistics are grouped into Primary and Secondary stream statistics.

​

Metadata

The Metadata section will show you the information of the actual content of the incoming live source in more detail. This helps you reference if you’re actually receiving the correct input signals.

​

Review recording history

The Channel History panel lists every recording job for a channel — queued, in progress, stopped, or completed.

1. On the channel card, click the More (three vertical dots) button.
2. Select Channel History.

The panel displays the following columns: A recording that was retried appears as a single entry labelled Attempt N, showing the latest attempt. Click Show earlier attempts to see the ones before it. A completed recording exposes a View Outputs button listing the files it produced.

Troubleshooting

​

Loss of signal (LOS)

LOS at start-up The channel’s Stream Status reads Waiting if no stream has ever connected, or Disconnected if one connected and dropped. The Channel Status does not change — it stays Ready To Record. The thumbnail shows the last frame it received, or a placeholder if it never received one. Starting a recording in this state is refused, and UP.Capture reports the reason: the source stream is unavailable, or the source is in an outage. No recording job is created. To resolve, verify the source is streaming and reachable, then check its configuration in Configuring Live Sources. LOS during an active recording In case of loss of signal during an active recording, UP.Capture will insert the LOS pattern configured on the channel in the Payload step. Once the signal is available again, the LOS pattern will be replaced with the valid contribution signal. The recording keeps running throughout, and its Capture Status stays Recording.
