What is an explainer video?
An explainer video is a type of corporate video used by enterprises for communication. An explainer video is usually a short, simple-formatted, and engaging video used to tell your customer what you offer. Establish empathy by relating to your customer’s problem. Show how your product or service solves that problem.
Explainer videos are great as a landing page for your product or service. They can also be an excellent sales tool to use as a first contact with a potential customer. Clients can also use them for conferences, trade shows, email sequences, and sales meetings.
The most common type of explainer video is a 2D explainer video, but is this the best way to explain your business, though? Its duration is usually shorter than 30 seconds; contrary to the majority's belief, the shorter is not the better. Let’s dig into the reason behind this claim!
Type of explainer video
2D Explainer Video
A 2D explainer video uses simple animated illustrations and narratives to break down the information of how your business works. This format is ideal for B2B brands, SaaS platforms, and medical firms—essentially any service with a process that may feel unfamiliar to the average customer. But it doesn’t work as well with a too complex procedure, because, dare we say, nothing too complex can be explained under 30 seconds.
2D Explainer Video Example
Sub-niche: Whiteboard Animation - A popular subset of 2D is the whiteboard explainer. These videos use a digital canvas and "hand-drawn" marker lines to build a story in real-time, making them highly appropriate for educational content.
3D Explainer Video
While they share the same goal of simplification, 3D explainer videos utilize three-dimensional motion graphics to add depth and realism. This format is significantly more versatile, allowing for a level of visual innovation and high-end polish that 2D cannot match. 3D is particularly effective for brands looking to showcase physical product mechanics or futuristic technology. It can also act as a source and be put in between your other corporate videos, such as case studies or corporate stories, and so on.
3D Explainer Video Example
Live-action Explainer Video
Live-action explainer, as its name suggests, features real people and environmental settings. This type of video is usually harder to pull off, as its required more investment in creativity, time, and money. Another reason companies might choose animated videos over live-action videos is that they are usually shorter. The mass audience has a much shorter attention span; they want something short and impressive to pierce into their mind. However, this is not always the case; the downsides that corporates sometimes miss are:
2D explainer videos can not explain if the process is too complex.
2D explainer videos lack human connection.
Live-action explainer videos provide a more professional perspective on your products or services.
Live-action Explainer Video Example
Live-action explainer videos are an excellent tool for humanizing and clarifying complex corporate operations. However, a purely instructional approach can often lead to a drop in viewer retention. By mixing live-action explainers with other video styles, companies can transform a standard process breakdown into a captivating visual story.
2BIG Production's collaboration with Willer Mobi highlights the convenience of the service through the case study of a specific family. The message is now more convincing and relatable.
Therefore, if you are a B2B business or a more professional company, we suggest using live-action instead of an animated explainer video. If you have not had the exact idea of how to write an explainer video script and want to go for the convenience anyway, don’t worry, we will show you the detailed steps to write an explainer video script so you can have the dependence in making choices.
How to write an explainer video script?
If your idea is the soul, then script writing is the backbone of your video. It is the collision with what you want to happen, with a logical sequence of what can be done to make that come true.
Here are the steps suggested to develop an explainer video script:
Step 1: Set your goal and purpose
Ideas can be great, but if they can not illustrate your purpose and ultimately your company vision, you need to refine them.
Step 2: Identify your target audiences
Each audience has their own way of consuming information,
Step 3: Plan the scenes
Develop your idea into a story, keep it simple to 5 - 8 scenes only. Write a rough description for each scene:
How do you want each scene to take place?
What do people (if there are any) do in that scene?
What is the vibe/ mood of that scene? And from the vibe/ mood, we can decide on music for later editing.
Are there any texts or messages you want to display for each scene?
Step 4: Create a mood board
If you want to create an explainer video script for your company, it is all about the agreement and discussion between colleagues and departments. Therefore, creating a mood board containing pictures, photos, videos, or sounds similar to what you have in mind will definitely help everyone understand better!
