Part 3. Highlighting Text for Different Types of Videos
As you can see, highlighting text in your videos with Filmora Mobile is super easy and can even be fun! But knowing how to highlight text isn't always enough, you also need to know when and where to use it effectively.
After all, different types of videos have different needs. What works for a social media reel might not be the best choice for a tutorial or a business promo. Understanding what makes each type of video successful and using text highlight effects in a way that fits can make a huge difference.
So, let's break down the best ways to highlight text for different types of videos, so you can make the most of this powerful effect!
● Tutorial Videos
Use box highlight subtitles to make key steps and instructions stand out. This helps viewers follow along easily without missing important details. Thankfully, if you use the AI Highlight in Filmora, there's no need to do it manually since it automatically adds box highlights, just like in the example below.

● Social Media Content
Go for vibrant and animated highlights to grab attention and keep engagement high. Bold colors, cool effects, and eye-catching animations work great for reels, TikToks, and other short-form videos.

● Vlogs
Keep it subtle when highlighting subtitles in vlog videos. Most vlogs have a relaxed and peaceful vibe, so using anything too flashy can be distracting and take away from the storytelling. Simple, stylish highlights work best to keep the focus on the content.

● Educational Content
Choose professional and easy-to-read text highlight effects to ensure clarity, especially if the educational video is for kids. Clean fonts, simple color contrasts, and well-placed highlights help viewers absorb information quickly.

● Gaming Videos
Add fun, energetic text highlight effects that match the fast-paced action in gaming videos. Bright neon effects, glowing text, and creative text placement can make key moments stand out. Instead of just placing text at the bottom, try different positions and add quick animations to keep the energy high and the visuals exciting.

Conclusion
Adding text highlight effects to your videos is a great way to make your content stand out and keep your audience engaged. So, this guide covers how to do it using Filmora Mobile, the best video editor for the job. With Filmora, you can highlight subtitles in different ways—manually for full control over details or with the AI Caption feature for a quick and automatic solution.
If you choose the AI Caption feature, you can also enable AI Highlight, which automatically detects key moments in your video and adds highlights to make them more visible. Combined with a full set of advanced editing tools, Filmora Mobile is the ultimate choice for highlighting text in any type of video, whether it's a tutorial, social media post, vlog, educational content, or gaming video.
