This article introduces simple methods for video editing that cannot be done in Teachme Biz, using apps that come standard with Windows 11.
Detailed operation manuals are also linked within the article.
When editing videos in Teachme Biz, you can trim videos, add markings such as text and shapes during pauses, and add subtitles.
However, it does not offer advanced editing features like those found in dedicated video editing software.
In particular, we often receive requests such as "I want to overlay audio" and "I want to change the playback speed."
That said, video editing is not without its drawbacks. There are disadvantages such as the time required for editing and the loss of ease when making revisions.
We have also summarized the pros and cons of video editing, so please take a look at that as well.

Video Editing Using Windows 11 Built-in Apps
Changing Video Playback Speed
This section explains how to change the playback speed of a video.
How to change video speed (Microsoft official page)
When users actually view a manual, they are often doing so alongside some other task.
Asking such users to watch a 10- or 20-minute video continuously is a very high bar, and as a result, the video often ends up not being watched at all.
For videos that can be understood even at a faster speed, creating them at 2x or 3x speed from the start is an effective approach that reduces the viewing burden and alleviates stress for the people watching the manual.
Additionally, the technique of changing the playback speed for only a specific portion of the video is also effective.
When creating video manuals, you may find situations such as:
- A cooking manual that includes a scene of endlessly stir-frying vegetables.
- A restocking manual that includes a scene of continuously pouring liquid.
In other words, there are cases where scenes are included that can be skipped once the necessary action is understood.
In such cases, speeding up only the stir-frying or restocking scenes to 10x or 20x as a fast-forward skip can significantly reduce the time required for people viewing the manual.
Creating a Video with Audio Using Clipchamp
This section is a manual for when you want to create a video with audio using your computer screen.
- When you want to add narration to a silent video, such as a system operation walkthrough on a computer
- When you want to use an auto-play video of a PowerPoint slideshow with added audio
This is useful in situations like these.
By recording system operations and other screen interactions together with explanatory narration, you can create more easily understandable videos.
By recording audio in advance using a voice recorder app timed to match the video, you can insert spoken instructions into the video.
(Finally) Pros and Cons of Video Editing
We have introduced video editing manuals along with various use cases, but videos and their editing come with not only benefits but also drawbacks.
Pros
- A high amount of information makes it easy to concretely visualize actual work content and procedures
- Adding subtitles and audio allows you to supplement what you want to convey
- Well-suited for focused "learning and memorization" in a dedicated block of time in advance
Cons
- Re-shooting and editing videos due to equipment or operational changes requires manpower and time
- Partial corrections and replacements are difficult
- Not well-suited for "referring" to only the steps you don't understand during spare moments
Create manuals with your purpose and update frequency in mind
- Is the purpose "pre-learning," or is it "reference during work"?
- Has it become over-engineered in quality?
- Considering ease of updates, is it something you can realistically continue to maintain?
Rather than focusing only on the benefits after editing, it is a good idea to keep in mind whether the time invested is truly worthwhile relative to the manual's purpose and the effects it will produce, and to be mindful of how you create your manuals.
