8 key benefits of adding text to videos using Synthesia

Adding text to your videos can offer several benefits to enhance the viewing experience and communication effectiveness:


Emphasize key points

Adding text to a video can underscore crucial information or points, ensuring they are not missed by viewers. Furthermore, on-screen text acts as a visual cue that draws attention, reinforcing critical messages or data when audiences might be inundated with information.



Even without considering subtitles, text on video can help in instances where audio is not available or viewers have sound turned off. This strategy is especially useful in social media contexts where videos often auto-play silently, ensuring viewers receive key information even without audio.


Visual interest

Text on video, when used with creative video editing, adds a visual layer that captures and maintains viewer interest. Moreover, animating text or integrating it innovatively with visual elements can create dynamic, engaging scenes that maintain a steady viewer engagement and aesthetic appeal.



Text can serve as guidance or instructions, directing viewers on what to focus on or what action to take next. Explicitly, text can seamlessly guide viewers through complex videos, providing clear instructions or succinctly summarizing preceding or forthcoming content, smoothing the viewer's journey.



Adding text to your video while utilizing consistent fonts, colors, and text styles can reinforce brand identity and messaging. Consequently, consistent use of on-screen text, aligned with brand font color and font size, creates a subconscious visual association with the brand.



Highlighting important phrases or keywords can help them stick in the viewer’s memory, reinforcing the message. Ensuring key phrases are visually presented aids in the repetition and recall of vital information, amplifying the video’s impact and viewer retention over time.



In instances where spoken words might be unclear or accented, adding captions and on-screen text can aid in clear communication. Especially in technical or specialist content, add text to serve as a helpful guide, to ensure specific terminologies are accurately communicated and understood.


Enhanced Learning

For educational content, on-screen text can bolster learning and retention by engaging multiple senses. Add text to cater to different learning styles, and ensure that both auditory and visual learners can assimilate the information effectively, broadening the video's educational reach.
