Known Issue: Primary Audio Auto-Selection for Live Streams
When an Epiphan device is configured with a Profile that includes multiple audio sources, the Primary Audio source may not be automatically selected correctly for live streams.
Impact: The live stream may broadcast audio from the wrong input. Depending on your setup, this can manifest in two ways:
- Different audio on each input - The wrong audio source is streamed (e.g., a room mic feed instead of the presenter mic). This is typically easy to identify.
- Same audio on both inputs - The audio content sounds correct, but a lip-sync mismatch occurs between the audio and video because playback is synchronized to the wrong channel.
Workaround: If your live stream Profile uses two inputs, manually set Input 2 as the Primary Audio source before broadcasting.
Recommendation: Always verify the audio source and lip sync during a test stream before going live.
To streamline documentation for the capture schedule interface, procedural information and technical details have been separated. If you are not familiar with them, review Details Around Scheduling Captures before executing the procedures below.
Administrators can generate new captures using the institution's capture appliances, available Universal Capture installations, and compatible Epiphan Pearl devices. One-off ad hoc captures can be launched directly from the appliance or room. However, Administrators more often use the capture dialog box to launch scheduled captures, whether recurring or non-recurring.
They are called scheduled captures because you must select a date / time for recording (even if it is only a few minutes from now), rather than configuring the information and launching immediately as you do with ad hoc captures. Before you begin, refer to the section at the bottom of this page regarding how and when term exclusion dates are enforced for scheduled captures.
Note: Live Captioning is available during a live stream, similar to turning on live captions in tools like Microsoft Teams or Zoom.
Closed Captioning is available after a recording is complete. Captions can be applied to scheduled, individual, or completed captures using supported providers, including 3Play Media, AI Media, Verbit, AST, and Rev.ai.
Supported Capture Devices
EchoVideo supports scheduled and ad hoc captures from the following device types:
Echo360 Appliances — EchoVideo Pro and EchoVideo Pod. Input selection is made directly in the capture dialog box.
Epiphan Pearl Devices — Pearl-2, Pearl Mini and Pearl Nexus. Input selection is replaced by Capture Profile selection (see Recording Profiles for Epiphan Devices).
Universal Capture — Software-based capture on Mac and Windows.
The steps in this article apply to all device types. Where the experience differs for Epiphan devices, this is called out explicitly.
Open the Capture Dialog Box
The capture dialog box, also called the scheduled capture dialog box, appears when an Administrator selects New Capture from the Captures page, as shown below.
It is the same as the one that appears when you select to schedule a capture for a particular section using the Schedule icon on the Courses page, as shown below. The Courses page method is the only way Schedulers can generate a capture or a capture schedule.
Then, from the section schedule page, select New Capture.
The capture dialog box that appears is identical in both methods. The only difference is that, when launched from the section schedule page, the Title (section name), Instructor (primary instructor, if any), and Publishing areas are pre-populated with the section information. This is shown in the figure below.
The pre-populated fields, identified in the figure below, can be edited if needed. It is there for convenience.
The fields to complete are otherwise identical and are covered in the procedural steps below.
Create a Scheduled Capture
- Use one of the above-cited methods to open the capture dialog box.
-
Enter a Title for the capture (required).
The title becomes the name of the generated capture(s) and the name of the classes and sessions auto-created to hold the capture when publishing to a section or folder.
-
Select an Instructor for the capture. The instructor is typically the person who runs the class or session being recorded. This is optional; if no instructor is selected, the Owner field will read None.
The instructor selected becomes the owner of the capture; the completed capture(s) will appear in this user's Library. If there is no owner, only Administrators / Schedulers can access the capture outside a section or folder until it is shared with another user or an owner is assigned.
-
If appropriate, enter the name or email address of a Guest instructor.
This is a text field designed to identify a guest lecturer for the capture schedule, if applicable. It is for informational purposes only.
-
Use the drop-down lists to select a Campus, Building, and Room where the capture(s) will occur.
Selecting a room also selects the device used to generate the capture.
-
Choose an Organization or Department to publish the capture(s) to.
Selecting an Org or Dept lets users associate captures directly with an Org / Dept without publishing them to a Section. This field may be required based on your Institution Settings.
-
The experience at this step differs depending on whether the room is assigned an Echo360 appliance or an Epiphan Pearl device.
7a. Echo360 Appliances (Pro / Pod / Universal Capture)
Select the Inputs to use for the capture(s). The device's configuration determines your options. The Inputs dropdown lists the available input combinations for the device, such as Display + Video, Display Only, or Video Only.
7b. Epiphan Pearl Devices
When the selected room has an Epiphan device assigned, the Inputs dropdown is replaced by a Capture Profile selector. Capture Profiles define which Epiphan channels (and their associated inputs) will be recorded.
You have three options:
Default Profile — The profile that has been configured as the default for this room. If no profile is explicitly selected, the default profile is used automatically. Every Epiphan room must have at least one default profile.
Named Profiles — Additional pre-defined profiles that have been created for this room during room configuration. Named profiles allow you to pre-configure different channel combinations for different use cases (for example, a "Camera Only" profile or a "Display + Camera + Document Cam" profile). These appear as selectable options in the profile dropdown.
Custom Profile — If the custom profile option is enabled for your institution, you can create a one-time custom channel configuration directly in the capture dialog. This allows you to select individual Epiphan channels and designate the primary audio source for this specific capture without modifying the room's saved profiles.
-
Select the output Quality for the capture(s). Your options include Standard, High, and Highest.
If you have not yet, review Details Around Scheduling Captures for information on what each of these settings means and the best circumstances for each selection.
-
Select whether to enable Closed Captioning for this capture. This option is available only if closed captioning is configured on the system.
When Closed Captioning is turned on for a schedule, it always uses the Closed Caption Configuration set as the system default.
-
Select whether these captures will be available via Live Stream. This means students can watch the class in real time from a remote location.
This toggle is not available until a section is selected for publishing. If you have not already, review Details Around Scheduling Captures for additional information on live streaming.
-
Select whether these captures will have Live Captioning. Live captioning provides real-time, automatically generated text during live content, allowing viewers to read spoken content as it happens, improving accessibility.
Note: Live Captions are limited to a maximum duration of 4 hours.
-
Enter the capture's Start Date. Today's date at Noon appears by default.
See also the section at the bottom of this page regarding how and when exclusion dates are enforced on capture schedules.
- For non-recurring captures, this is the date on which the capture will occur.
- For recurring captures (a capture schedule), this is the first date on which the capture will occur.
- Enter the Time Range for the capture.
- Select whether the capture Repeats or not. Your options are:
- None - This is a one-time event.
- Weekly - This creates a recurring event on one or more days a week.
- If you select a Repeats option, the dialog box expands to show additional required options:
- Identify the weekly frequency of the capture; enter 1 for every week, enter 2 for every other week, etc.
- Identify an End date for the capture (the last date on which the capture will occur).
-
Use the sliders to select which days of the week the capture occurs.
Be sure to change the end date for recurring captures. The End Date defaults to today's date; if you do not change it, the capture will not recur.
- To publish to a Section
-
Use the Course, Term, and Section drop-down lists to identify the location to which the completed captures are to be published. Selecting a publishing location is optional.
If you have not yet, review Details Around Scheduling Captures for additional information on generating captures with and without section association.
-
Use the Availability settings for the selected Section to configure date-based availability for the completed captures. Or accept the defaults.
For example, you can make the capture immediately available and then set it to Unavailable after a set number of days.
By default, all published captures are available Immediately and are Never unavailable. Availability is for student viewing; instructors can always see published captures.Availability settings are active only when a section is selected. Logically, captures that are not published to a section are not available to students and therefore do not require an availability / unavailability set.
Additionally, capture availability / unavailability depends on the capture start time.
For example, a capture set for 10-11 am with a 3-day delay in availability becomes available at 10 am, 3 days after it is recorded. A capture that is available immediately but set to be unavailable after 5 days will be made unavailable at 10 am, 5 days after it is recorded. -
To publish the same recording to more than one section, click ADD SECTION and repeat the process. You can publish to up to 10 sections.
For information on linking to an LMS Course, see Linking a Section and Capture Schedule to an LMS Course.
- If you add another section, set the availability for completed captures for subsequent sections as described above (or accept the defaults).
- To remove a section, click the X located to the right of the section.
-
- To publish to a Folder
-
Use the ADD FOLDER button to open the folder selection window and select any folder for which you have Add permissions.
If you have not yet, review Details Around Scheduling Captures for additional information on generating captures with and without folder association.
- To publish to multiple folders, click ADD FOLDER and repeat the process. You can publish to up to 10 folders.
- To remove a folder, click the X located to the right of the folder.
-
- When finished, review all of the information in the dialog box. If correct, click SAVE.
The figure below shows a completed capture dialog box where the resulting captures will have the following attributes:
- The generated captures will be published to two sections and a folder.
- Both of those sections will have classes automatically created to hold the completed captures.
- The class dates and times will be the same in both sections, and the capture to be published will also be the same in both sections (one capture published to two different locations).
- The captures will be available immediately for students, but will become unavailable after 14 days, for both sections (availability can be set differently per section if needed).
If publishing a single set of captures to multiple sections / folders, keep in mind that if a user chooses to Edit the capture, the changes will apply to all published versions.
