A hybrid seminar is a type of seminar that connects participants who are gathered at a venue with online participants simultaneously.

With remote work and hybrid work becoming commonplace, it's becoming increasingly difficult to reach people through seminars that are limited to offline events.

Once the online streaming system is in place, lectures can be delivered in real time to employees and business partners located far away, and archived versions can also be provided.

However, if the stream is interrupted or the video and audio are distorted, participant satisfaction will decrease.

This article explains the equipment necessary for a successful hybrid seminar, as well as common problems and how to address them.

If you are having trouble with hybrid seminars, please contact us at LIFE.14 Co., Ltd.

Leveraging our extensive experience in designing the technical aspects of international conferences and corporate events, we propose equipment configurations and operational support tailored to the scale of your broadcast and the format of your seminar.

Equipment required for a hybrid seminar

To successfully conduct a hybrid seminar, it's crucial to consider the in-person format and the online streaming format separately.

The essential equipment categories you should be aware of are as follows:

Streaming equipment
Venue display equipment

The following sections will provide detailed explanations for each of these points.

Streaming equipment

On the broadcasting side, it's necessary to create a workflow that includes recording video, capturing audio, switching screens, and sending the content to the broadcasting destination.

The necessary equipment is as follows:

Equipment for shooting video
Equipment for transmitting sound
Equipment for switching between video feeds
Equipment used for live streaming

Let's take a closer look at each of their roles.

Equipment for shooting video

Simply showing the venue is not enough to convey the content to online participants.

When choosing a camera, it's important to consider how to capture the presenter's expressions, the content of the slides, and the overall atmosphere of the venue.

The following are some of the pieces of equipment commonly used for video shooting:

Professional video cameras
SLR camera
Multiple cameras

Professional video cameras are suitable for long-term use.

Since seminars often last over an hour, it's safer to choose equipment that is less likely to stop midway through.

A single-lens reflex camera is ideal when you want to make the presenter look their best.

However, for prolonged continuous operation, attention must be paid to heat and power supply management.

Don't just choose based on appearance; you also need to check if it can withstand the actual duration of the event (whether it will overheat or run out of battery).

Furthermore, in hybrid seminars, even if only the presenter is shown, it tends to be difficult for online participants to see.

In addition to cameras for the presenters, being able to use separate cameras for presentation materials and a panoramic view of the venue will make it easier to create a more user-friendly broadcast.

Equipment for transmitting sound

In live streaming, the clarity of the sound is even more important than the clarity of the video.

Even if the screen is somewhat simple, you can still follow the content, but if the voice is difficult to hear, the message itself won't be conveyed.

The essential audio equipment you should have is as follows:

Wireless microphone
Desktop microphone
mixer

Wireless microphones are suitable for presentations where the instructor is walking around while speaking.

Without cables, it's easier to move around and less likely to disrupt the flow of events at the venue.

For discussions or presentations with multiple speakers, lavalier microphones and headset microphones are also good options.

Desktop microphones are convenient equipment for panel discussions and seated seminars.

If you don't consider how to place things according to the number of people you're talking to and where they're sitting, you're more likely to pick up too many items or miss some.

A mixer is a piece of equipment that combines and adjusts the sound from multiple microphones or PCs.

Its role is not to simply mix the speaker's voice, the moderator's voice, and the video playback sound as they are, but to adjust them into a format that is easy to listen to during streaming.

Even on a small scale, including it helps to equalize volume differences and improve stability.

Equipment for switching between video feeds

In a hybrid seminar, the way information is conveyed changes depending on which video is shown.

The ease with which online participants can view the presentation depends on how well you can switch between showing the speakers, materials, and the venue.

The equipment used for switching between video feeds is as follows:

Switcher
HDMI capture

A switcher is a device used to switch between camera footage and slide screens.

Because the camera can switch between showing the speaker and displaying larger versions of their materials in accordance with their presentation, the live stream screen is less likely to become monotonous.

HDMI capture devices are used to capture video from multiple devices, such as cameras and PCs, all at once.

One thing that's easy to overlook is that simply connecting doesn't guarantee an image will appear.

Since the video conditions can differ depending on the input equipment, it's important to decide on the connection combinations in advance.

Equipment used for live streaming

After combining the video and audio, you'll also need equipment to reliably transmit it to the distribution destination.

If the equipment used for streaming is unstable, the online stream may stop working even if the in-person event is running smoothly.

The equipment required for streaming is as follows:

Streaming PC
Capture device
distribution software

A streaming PC is the central piece of equipment used to send both video and audio to the destination.

Rather than simply ensuring high performance, it's more important that the system is designed to remain stable even after prolonged use.

A capture device is equipment used to import camera footage into a streaming PC.

If you are using an external camera, there is a possibility that the video may not be displayed on the day of the event, so you need to check in advance how to import the video to your streaming PC.

Streaming software is used to optimize the way the screen is displayed.

For example, it is used in the following operations:

Arrange the materials and the speakers side by side.
Enter a title
Display the waiting screen

You will need to adjust the image quality and file size to suit the recipient.

Venue display equipment

In hybrid seminars, it's not just the screen shown to online participants that matters, but also what and how it's shown to participants at the venue.

The following is a list of equipment commonly used by the venue staff:

projector
monitor

Ensuring that the venue is easily visible from the audience's perspective makes it easier to create an operation that isn't solely focused on the live stream.

Let's take a closer look at each of these below.

projector

A projector is a piece of equipment used to project slides or videos onto a large screen in a venue.

Whether participants can read the materials depends not only on the content, but also on factors such as brightness and screen size.

If you use equipment that doesn't provide enough light in a large venue, the text will be difficult to read from the back.

Conversely, for smaller venues, it's often sufficient to avoid an unnecessarily large setup.

It's important to consider the venue size, lighting brightness, and screen size together.

monitor

The monitors can be used not only for on-site attendees, but also for speakers and organizers to check things out.

At the venue, dividing roles as follows will help reduce errors.

A screen for presenters to view their materials.
A screen where the operator checks the next video to be shown.
A screen to check the content being streamed.

If you try to rely solely on a projector, it can be difficult to see the details you want to check, so it's important to consider placing the necessary screen in the necessary location.

Factors that influence the configuration of hybrid seminar equipment

The equipment configuration for a hybrid seminar broadcast is not determined solely by the size of the venue.

The main criteria to consider when choosing equipment are as follows:

Number of participants
Seminar format
Required delivery quality

Even with the same hybrid seminar format, the required number of machines and operational structure will change depending on the circumstances.

The following sections will provide detailed explanations for each of these points.

Furthermore, based on our experience in technical design cultivated through international conferences and corporate events, we at LIFE.14 Co., Ltd. offer consultations on equipment configurations tailored to the scale of distribution and seminar format.

If you are unsure about the configuration your company needs, please feel free to contact us.

Number of participants

The amount of equipment needed doesn't necessarily increase as the number of participants increases.

The important thing is to distinguish between the speakers (performers) and the audience (spectators).

If the number of speakers increases, the number of cameras and microphones needed will also increase, as will the amount of work required for switching between them and adjusting the volume.

On the other hand, even if the audience size increases, the number of cameras and microphones generally doesn't change significantly.

For small-scale seminars, it's sometimes possible to run the event with just one camera to show the speaker and a microphone that can clearly pick up their voice.

If the focus is on sharing documents, the way you present the video can be kept relatively simple.

For medium-sized events, you'll want to show not only the speakers' expressions but also the venue and presentation materials, so it's easier to stream if you increase the number of cameras to two or more.

Switching between video feeds will often be necessary, so it's a good idea to consider equipment to streamline the operation.

As projects scale up, the amount of video and audio to manage increases dramatically.

Because the number of things to pay attention to simultaneously increases, including speakers, moderators, Q&A sessions, and venue sound, it's necessary to consider not only the equipment but also the arrangement of the people operating it on the day.

Seminar format

In a hybrid seminar, the necessary equipment will vary depending on the format in which it is conducted.

The key concepts to keep in mind for each format are as follows:

Lecture type
Dialogue-style
Panel discussion

Organizing your content to match the format makes it easier to both view and manage your streams.

The lecture format is a relatively easy format to implement.

Having a camera to show the presenter and a system to display the presentation materials will make it easier to convey the content.

On the other hand, basic flaws such as difficult-to-read materials, distant voices, and dark presentations are prone to appearing, so it's important to carefully prepare the foundation rather than focusing solely on appearances.

In a dialogue format, the number of speakers increases, which means both the number of microphones and the number of video transitions also increase.

Since it's necessary to create a screen that clearly shows who is speaking, cameras that can follow the speakers and a system for ensuring proper audio quality are crucial.

In a panel discussion, multiple people take turns speaking, so proper audio quality is especially important.

Because there are often significant differences in volume and frequent changes in speaking style, simply placing microphones down can make it difficult to achieve a cohesive result in certain situations.

It's necessary to consider both the ease of listening for those at the venue and the ease of listening for those online when designing the presentation.

Required delivery quality

The necessary equipment will vary depending on how clear and easy to listen to the presentation is intended to be.

The approach is as follows:

Minimum distribution
Corporate event quality
Video production level quality

While minimal streaming setups allow for a smaller configuration, they tend to concentrate the load on a single PC.

While preparation is lighter, it becomes more difficult to switch between videos and vary the presentation style, and there tends to be less leeway during the actual broadcast.

If you want to ensure a professional-quality corporate event, it's best to include equipment for switching between video feeds and a system for adjusting the audio.

Showing the speakers, materials, and venue in different ways at each stage makes the broadcast easier for online participants to understand.

Furthermore, when you want to pay attention to the presentation as well, you need to consider things like switching between multiple cameras, adjusting the layout on the screen, and the stability of the network connection.

As image quality increases, so does the load on the network and PC. Therefore, it's important not to decide based solely on appearance, but to choose a configuration that will run stably until the day of the event.

Equipment problems that are likely to occur in hybrid seminars

In hybrid seminars, because venue operations and online streaming are managed simultaneously, there is an increased likelihood of equipment malfunctions occurring in certain locations.

The following are some situations that require particular attention:

Common problems that occur during online streaming
Common problems that occur at the venue

Identifying where problems are most likely to occur beforehand makes it easier to prioritize preparations.

Now, let's look at each of these in detail below.

Common problems that occur during online streaming

The problem with online issues is that even if everything is running smoothly at the venue, the content may not reach the viewers.

The most common examples are as follows:

Types of problems	Common occurrences	Main cause
Audio trouble	The voice is too quiet, inaudible, doubled, feedback.	Microphone setting discrepancies, volume balance issues, speaker feedback
Streaming trouble	The video and sound stop or cut out.	Insufficient network connection, overload on the streaming device, incompatible streaming settings.
Video trouble	The screen doesn't display anything, goes completely black, or glitches during transitions.	Faulty cables, incompatible equipment, mismatched output settings.

When these kinds of problems occur during online streaming, it affects the viewing experience.

Common problems that occur at the venue

Venue issues directly impact not only participant satisfaction but also the presentation flow of the speakers.

The points to pay particular attention to are as follows:

Types of problems	Common occurrences	Main cause
venue sound system trouble	Difficulty hearing, feedback, noise mixed in.	Excessive microphone volume settings, speaker placement issues, and faulty power supply/wiring.
Venue video trouble	The video doesn't switch, the screen is dark, or the screen goes blank.	Poor equipment combination, mismatch with lighting, inconsistent settings
Venue display problems	The text is small, the lighting is dim, and it's not visible from behind.	Insufficient equipment output, mismatched settings, and complex connection paths.
Equipment operation problems at the venue	Forgetting to press the button to stream/record, delay in switching, forgetting to unmute.	Unclear procedures and roles, insufficient operational design

When such problems occur at a venue, they can easily affect the progress of the event itself.

By understanding common problems and their causes in advance, you can make preparations and on-the-day responses much smoother.

Troubleshooting methods for equipment problems in hybrid seminars

With hybrid seminars, if a problem is discovered after the live stream has started, it becomes difficult to recover.

To minimize mistakes, here are some items you should organize beforehand:

Technical pre-checks
Operational preparations
Pre-production preparations for the broadcast

From here, we will explain the things you should keep in mind before the actual event.

Furthermore, we at LIFE.14 Co., Ltd. provide technical support for events, including audio, video, streaming, and filming.

If you would like to check the streaming environment and equipment configuration during the preparation stage, please see our service area and track record.

Technical pre-checks

To minimize equipment malfunctions, it's important to check the venue's facilities and the streaming conditions separately.

The following are some things you should review beforehand:

Check the venue infrastructure.
Check the streaming environment

The following sections will provide detailed explanations for each of these points.

Check the venue infrastructure.

The stability of the live stream depends on the venue's network and power supply conditions.

Even if you have all the necessary video and audio equipment, if the internet connection is unstable or there isn't enough power, the system is more likely to stop working during the live broadcast.

The items you should check beforehand are as follows:

Check if a wired internet connection is available.
Check the power capacity and the location of the outlets.
Check the venue's sound equipment and connection conditions.

In particular, it's safer not to rely solely on the venue's Wi-Fi connection.

The venue's network can easily become congested with attendees connecting, so securing a wired connection for streaming will help ensure a more stable connection.

Regarding the power supply, simply being able to plug in devices is insufficient; it's crucial to have a configuration that can handle multiple devices running simultaneously without shutting down.

Additionally, if you plan to use the venue's built-in sound equipment, it's a good idea to decide beforehand where the sound will be received from and where it will be returned to, which will help prevent confusion during the actual performance.

Check the streaming environment

The required equipment and settings will vary depending on which streaming service you use.

The items I would like to check are as follows:

Zoom
Teams
YouTube Live

While conference-style streaming makes it easy to interact with participants, the way it looks can vary depending on the viewing environment.

On the other hand, while streaming services offer a more stable viewing experience, they tend to have a time lag compared to live events held at the venue.

Whichever option you choose, be sure to consider the venue's internet speed, the load on the streaming PC, and the video's bitrate, as these factors can easily lead to instability during the actual event.

Operational preparations

Even if the equipment is in place, if the schedule and division of responsibilities are unclear, confusion is likely to occur during the actual event.

The following are the key points to keep in mind regarding operations:

Decide on the rules for running the event.
Conduct a rehearsal.

Planning not only the techniques but also the actions to be taken on the day of the event can help reduce the risk of accidents.

The following sections will provide detailed explanations for each of these points.

Decide on the rules for running the event.

In hybrid seminars, there is a time lag in the responses of in-person and online participants.

If the moderators do not take that difference into account, the flow of the discussion is likely to break down during question-and-answer sessions and voting.

The steps we want to decide beforehand are as follows:

A time will be set aside for questions and answers via chat.
Conduct voting and surveys with ample time to spare.
The host pauses to account for any delays in the broadcast.

For example, if questions are only asked by people raising their hands in person, it becomes difficult for online participants to join in.

Therefore, having participants submit questions via chat and then having the moderator pick them up makes it easier to manage both in-person and online participation.

Make sure to include waiting times and cues for transitions in the script.

Conduct a rehearsal.

Even just running through the code once before the actual performance can help you find many problems early on.

The things I would like to confirm are as follows:

Voice verification
Video confirmation
Delivery confirmation

For audio, we check for volume, noise, echo, and feedback.

The video will be used to check how the presenters appear, how easy the materials are to read, and the flow of transitions between segments.

For live streaming, it's important to check whether the stream is actually sent to the destination, whether there are any delays, and whether the recording is running smoothly.

If possible, it's safer to use the same equipment, network connections, and lighting conditions as the actual event.

Pre-production preparations for the broadcast

Before you start streaming, it's important to configure the public settings and clear up any rights issues.

The following are the things we want to decide before the release:

Obtain the necessary permissions for distribution.
Implement security measures
Determine the scope of public access for recorded data.

To prevent misunderstandings after the event, thorough organization before public release is essential.

The following sections will provide detailed explanations for each of these points.

Obtain the necessary permissions for distribution.

When you stream a seminar, not only the speakers' faces and voices, but also the appearance of participants and the content of the materials may be broadcast to the public.

To avoid problems later, please check the following items in advance.

Confirm whether it is okay to broadcast the speakers' faces and voices.
The area in which participants will be visible should be determined in advance.
Check how diagrams and photos in the slides are handled.
Check how background music and video materials are handled.

Content that wouldn't be problematic if simply shown at the venue may be treated differently when streamed or released as a recording.

Clearly stating whether or not filming or live streaming will be permitted, and the scope of its publication, in registration instructions, application guidelines, and venue notices can help reduce misunderstandings.

Implement security measures

When conducting online broadcasts, it's necessary to be careful about things like allowing uninvited people to enter and preventing the leakage of documents.

Especially in seminars for businesses, it's crucial to consider how information will be handled.

The following are the things you should prepare in advance:

Manage participation by limiting the URLs used.
Set a password and waiting room.
Strengthen the protection of streaming accounts.
Narrow the scope of sharing for recordings and documents.

If the venue is left in a state where people who are not participating can freely enter, problems will arise that cannot be prevented by venue management alone.

It's reassuring to have consistent company rules regarding everything from how to handle participation links and permissions for recorded data to how to display distributed materials.

Determine the scope of public access for recorded data.

If you plan to save a recording, you need to decide beforehand who will be able to watch it.

Problems often arise during post-event sharing rather than on the day of the broadcast.

The items we want to decide beforehand are as follows:

Decide whether to limit it to internal use only.
Decide whether to limit it to participants only.
Decide whether to make it public.
Determine the publication period and how redistribution will be handled.

While recording is convenient, once it's widely shared, it becomes difficult to retrieve.

Deciding in advance on the scope of publication, publication period, whether or not reproduction is permitted, and whether or not editing is allowed will help prevent inconsistencies in decisions after the event.

If the video contains confidential company information or includes images of participants, it's safer to have a process in place to review it before publication.

If you want to make your hybrid seminar a success, consult with a company with a proven track record.

Hybrid seminars cannot be conducted successfully simply by having the necessary equipment.

The necessary structure will vary depending on the number of participants, how the seminar will be conducted, and how easy it is to see and hear.

Furthermore, in order to ensure that the live stream on the day of the event is not interrupted, it is important to plan everything in advance, from the network connection and venue equipment to the audio, video, and the flow of the event.

Especially in corporate seminars, technical issues such as inaudible sound, freezing video, or difficulty viewing materials directly impact participants' impressions.

Therefore, instead of trying to connect the equipment on the spot, it's necessary to decide in advance on the streaming method, equipment configuration, and how to proceed on the day, in accordance with the purpose of the event.

Since the event is aimed at both in-person and online participants, it's not sufficient to prepare for only one of them.

We at LIFE.14 Co., Ltd. provide technical support, including audio, video, streaming, and filming, for corporate events and international conferences.
