Video conferencing software development is at its peak. Platforms like Zoom, MS Teams, and Google Meet dominate the market. Discord has seen an increase in daily active users.

The reason is the increased demand for remote collaboration tools. People need to keep socializing and working, and the abovementioned solutions have become an alternative to real-life communication.

Online communication affects lots of businesses as well. They need to adapt to new norms and invest more in digital communication as a core way of interacting with clients.

The question that may spring into your mind is, “Do I need to start digital disruption in my company, too, and switch to online communication?”. Our answer is yes. Business communication software can benefit your company in employee efficiency, client engagement, and appeal to larger audiences.

Let us guide you through the emerging trends in video communication, vital features, and success stories. You can rely on Softermii’s extensive experience, with numerous video conferencing platforms like PractiCall, HIPAA Telmed, and Events10x in its portfolio. So let’s take a closer look at video calling platform development.

Why Video Conferencing Software Has Become So Crucial

The video conferencing software market is expanding at a breakneck pace. In 2022, it was valued at $25 billion, as per Global Market Insights. By 2032, it is projected to reach $95 billion.

Build a virtual meeting software

The Gartner report showed the worldwide social software and collaboration market growth to total $5.1 billion in 2022, an increase of 14% from 2021. Moreover, Gartner predicts that by 2025, nearly 65% of application software providers will have included different renditions of social software and collaboration functionality in their portfolios.

This data clearly shows how online communication undergoes massive change. People discover new ways of socializing, and companies seek ways to provide an offline-like experience using digital technologies and introduce new tech opportunities to their clients.

For example, workplaces today hardly resemble the same ones during pre-pandemic times. The crowdsourcing session by Deloitte on workplace strategy, virtual collaboration, and workforce reskilling found that:

  • Organizations were not as ready as they thought for the virtual workplace
  • Companies should redefine their use of collaboration tools to pioneer a new way of working
  • Managers needed to prepare to support the culture of the team and the overall system

These problems are dramatically reflected in such activities as organic collaboration, innovation, strategy sessions, and relationship building. But things have started changing: companies deploy security infrastructure for remote workers, conduct workshops online, and organize virtual team buildings via Zoom.

Business executives also plan to stick to a hybrid work model. This model considers employees spending three days in the office and the remaining two days working from home. According to Gallup, 8 out of 10 employees work hybrid or remotely.

Custom video conference software

As for business, the same applies to new strategies for operating and improving customer engagement. Those will require cloud technologies, including video meetings. About 20% of companies invest in digital transformation, considering it the most important area of their concern.

Conferencing software development

Clients value new opportunities for remote interaction that saves time and helps to keep the safety measures.

Types of Video Conferencing Platforms

Before kicking off a development process, define the type of your software. You can interview business analysts to determine what business activities require a video collaboration platform.

As an experienced team of developers, we highlighted the key types of video calling platforms our clients need:

Type

Description

Pros

Cons

Video conferencing platforms

These platforms provide video conferencing, messaging features, and screen recordings. Additionally, some of them have external integrations for appointment management.

These platforms don’t require many resources as they adjust to users’ devices and internet capabilities. They usually support up to 50 conference members simultaneously.

These may not suit the corporate needs of some companies, thus, are not the best option for remote work.

Messengers

These are messengers like Facebook, Telegram, WhatsApp, and Apple’s Facetime/iMessage that have a video chat feature.

Except for quick message exchanges, they provide opportunities for video chats. Some of the messengers allow holding calls typically for 2-30 people. Some apply AR/VR technologies to enable users to use custom masks and animations.

Messengers serve as an additional communication tool for remote employees but cannot replace video conferencing software and online collaboration solutions.

Online collaboration software

Video conferencing is not the only option for companies seeking remote collaboration. They require proper connectivity covering all corporate needs, which this kind of software offers.

Online collaboration tools offer extended functionality, including messaging, video and audio calls, sharing documents, external tools integration like Jira & Google Calendar, and group channels.

Plenty of solutions on the market provide the same functionality as Microsoft Teams and G-Suite. Still, they are built differently.

Custom video conferencing solutions

These are video conferencing platforms built from scratch, meeting all requirements of a specific company.

Companies seeking privacy use these tools. These solutions are suitable for internal work ecosystem integration and allow for extensive customization following the business needs.

These platforms may be costly to develop. Plus, companies have to take care of cybersecurity concerns.

Entertainment platforms

Video chats are not only applicable for work but leisure as well. Having fun with friends or playing video games has become standard with entertainment platforms like Discord.

These platforms allow playing games, arranging video conferences, streaming favorite games, and having group & private chats.

These platforms are usually not suitable for working purposes, only for entertainment.

How to Create Video Chat Software?

All video conferencing platforms, as mentioned above, might work for the IT or creative industries. However, telemedicine, real estate, banking, insurance, events & exhibitions industries require deeper integration with local IT infrastructure.

Hiring a team of software developers would be an option for creating a custom platform. The main advantage is that you can design your software with compulsory features, built-in integrations, and levels of accessibility. Moreover, hiring a team means they could also adapt to your security requirements.

So, how to build a virtual meeting software with a team of professionals? Here are the critical steps for creating your video-based platform:

Define the Requirements

Firstly, you need to understand the target audience. Secondly, consider all the possible use cases of your platform. Make a list of them, so the team gets a better understanding of your requirements.

Choose among 120 software specialists

Hire an offshore dedicated team or a few team members for your project. We guarantee 10% of deviation in deadlines and cost.

Select the Team

This point includes searching for and hiring an in-house team or an outsourcing company. Usually, outsourcing teams are easier to hire and do onboarding. They already have expertise in particular industries, a team of developers, hiring managers, and customizable engines. All those means you’ll get a faster delivery than hiring a whole in-house team.

You should also consider that you need to hire about 10-12 specialists for an in-house team. When the development process is complete, you’ll need to leave only 5-6 specialists for QA and additional features development.

Get a Proof of Concept (POC) or MVP

This point is crucial when you have no clear vision of what your product or service should have. Companies use PoC and MVP to collect feedback, check hypotheses, and test the business model.

PoC and MVP include developing a prototype by a team of UI/UX specialists to provide the design for your platform. It also allows you to evaluate potential use cases and the software’s usability. A team of business analysts would help you uncover more opportunities you could use.

Video conferencing software development

When you find a perfect match with design, a team of video conferencing software developers and engineers will develop technical requirements and a platform with basic features to get it tested.

Usually, PoC and MVP stages take about 4-10 weeks and cost from $15,000 to $25,000.

Get to Know Your Team

The team of video conferencing software developers comprises various specialists. Each of them is responsible for different aspects of the platform:

Backend Developers

Backend developers are responsible for building server logic, implementing video and security protocols, and connecting all the required APIs. The latter is used for external software integrations like payment gateways or cloud services.

Frontend Developers

Frontend developers are responsible for building the final look of your custom video conference software. They get all the designs and mockups and implement them as separate working elements in your platform.

UI/UX Designers

As we previously mentioned, designers are responsible for your platform’s look. They design mockups and transfer them to a team of frontend developers.

QA Specialists

The quality assurance team provides manual testing of your software. If QA specialists find any bugs, they’ll instantly notify developers to fix them. QA allows you to avoid critical issues before the release and quickly resolve any if they appear after the launch.

Project Manager

Project managers are the key people you will communicate with. They are responsible for meeting deadlines and managing developers. They can also provide you with updates and offers to improve your project.

DevOps

DevOps engineers put together all the pieces that make up a project. They know the specifics of programmers, testers, and system administrators and help to simplify their work.

Solution Architect

Solution architects provide the team with the technical documentation, standards, and workflows for creating a unified product.

UI Design for Video Conference Platforms

Pay attention to UI design if you want to make software for video conferencing that will look relevant in the future. Some of the best practices include:

  • Making the user interface simple as we did in our Parta app.

Video conferendcing platform development

  • Using common elements and paying increased attention to the design’s consistency.

Video conferencing solution

  • Using typography and color to create a visual hierarchy of the contents of your platform.
  • Using colors, fonts, and visual elements intentionally, not just because they look nice.
  • Opting for responsive design, suitable for all devices.

Test Scenarios for Video Conferencing Software

As we mentioned in our guide on how to make a video conference platform, such software must be brought to perfection by QA specialists. See what they can test:

Audio Quality

Checking audio quality involves using algorithms such as Perceptual Objective Listening Quality Analysis (POLQA) or Virtual Speech Quality Objective Listener (ViSQOL). These allow specialists to determine the audio stream’s quality.

Video Quality

QA specialists check video quality with the Blind/Referenceless Image Spatial Quality Evaluator (BRISQUE). It helps score each frame’s quality in the video.

Video Frame Rate

The video frame rate is the number of frames per second, and the standard for TV and movies is 24 frames. It’s what you should strive for in video conferencing platforms to provide smooth video movement.

Delay / E2E Latency

Video delay is acceptable in video conferencing platforms, but it should not exceed 500-700ms. Specialists can use POLQA algorithms to measure latency.

Network Bandwidth

Network bandwidth impacts all the indicators mentioned above. In addition, it varies by country and network provider. Yet, it can be influenced during testing by setting custom indicators of bandwidth, router queue size, etc.

Softermii Experience

Video conferencing is one of the core niches we work with. We’ve implemented video conferencing into social networks, property management, telemedicine, and online events applications. Here are some of our successful projects:

HIPAA Telmed

Make a video conferencing platform

We provided development services for HIPAA Telmed. It’s a video conferencing app for accessible healthcare and medical advice. This platform is used both by doctors and patients for remote health consultations.

We’ve built HIPAA Telmed with the use of WebRTC technology. The platform underwent much customization as we’ve implemented video and audio calls, messaging, and appointment management. The application uses HIPAA, a US medical security protocol.

Events10x

Create video conferencing app

We’re also proud of our collaboration with Events10x, a custom hybrid and virtual events platform. The client needed software for organizing conferences & exhibitions online. The app had to include private and group networking, broadcasting & messaging. The most challenging part was to provide all these features to 15,000 users simultaneously.

Our team had a tight deadline because the virtual expo software was dedicated to launching a huge online event in the UAE. Thanks to our VidRTC engine, we could save two months of development time and meet the deadline. The client was satisfied with the result and held the event successfully.
