Looking to create viral TikTok videos that capture attention and grow your following? This comprehensive guide, powered by Filmora's powerful AI video editor, is your ultimate toolkit. We'll show you how to leverage AI-powered features to effortlessly edit stunning videos on your mobile, desktop, or directly online. Dive in to discover a step-by-step process—from initial planning to using Filmora's free AI tools—to ensure your content is not only creative but also designed for maximum views and audience engagement. 

Part 1. Plan Your TikTok Video Before You Shoot

Before jumping into editing, you need to map out your content. If you want to learn how to make TikTok video content that performs well, start by laying the groundwork. A little preparation helps your message come through clearly and saves time during the editing.

Here's what to plan before filming:

1. Start with a basic idea

Think about what kind of video you want to make. It could be something funny, relatable, informative, or aesthetic. Your idea doesn't need to be complex, just clear enough to build on.

2. Check trending sounds and styles

Scroll through your For You page or TikTok's Discover section. Look for viral sounds, hashtags, or editing styles that could fit your idea. Save a few that work for your concept.

Choosing the sound early is key because it often shapes the pacing, transitions, and overall feel of your video. TikTok's algorithm also favors content that uses popular audio; thus, it can help boost visibility.

3. Choose your format

Now that you have the sound and general idea in mind, think about the best way to present your content. Some common formats include:

• Skits or short dialogues
• Tutorials or step-by-step demos
• Vlogs or "day in the life" clips
• Before-and-after transformations
• Product showcases or mini-reviews
• Lip-sync or trend participation

If you're learning how to create a TikTok video for your brand or niche, sticking with one format per video keeps it simple. A clear format also helps your audience know what to expect from your video.

4. Know your audience and message

Before you shoot, think about who you're talking to and what you want to say. Are you trying to teach something, make someone laugh, or promote a product?

Your audience could be students, beauty lovers, fitness fans, pet owners, or anyone within your niche. Knowing this helps you speak their language and keep your video in line with what your viewers enjoy.

5. Outline your shots or script

Even if your TikTok video is only 15 seconds long, jotting down a quick list of scenes or actions can help it flow better. You don't need a full storyboard, just a loose structure to keep your filming focused and avoid capturing clips you won't use.

You can write this in your Notes app or sketch it out, whatever helps you stay on track while filming.

6. Plan with editing in mind

As you film, keep your editing in mind. For example:

• If you want to match your clips to a beat, leave space at the start and end of each shot. This gives you more flexibility when trimming and syncing later.
• If you're adding text overlays, leave blank space in the frame, such as above or below your subject. Thus, text doesn't cover important visuals.

Planning ahead helps you a lot once you move on to the editing steps. Now that your plan is ready, let's move on to how to edit TikTok videos using your phone.

Part 2. How to Make a TikTok Video on Your Phone

When learning how to make and edit TikTok videos, using your phone is the fastest and most accessible way to start. You can use TikTok's built-in editor or switch to a third-party app for more advanced tools and creative flexibility.

Here are two simple methods to create TikTok videos right on your phone.

Method 1. Using TikTok's Built-in Video Editor

TikTok's in-app tools are simple and great for quick edits. It lets you record, trim, add effects, and post, all in one place. Here's how to create and edit TikTok videos using the in-app editor:

Step 1Open TikTok and tap the Plus (+) button at the bottom of the screen.

Step 2Choose to record a new clip or upload existing footage.

• To record, slide the duration meter to 15s, 60s, or 10m, then tap the Record button. You can pause and resume as needed. When you're done, tap the Checkmark to move to the editing screen.
• To upload clips, tap the Gallery icon and select at least one video or photo. Then tap Next to begin editing.

Step 3Do a quick edit or tap "Edit" for advanced options.

• Once you reach the editing screen, you'll see several quick-edit tools right away. Here, you can add text, apply stickers, use visual effects, or choose a filter with just a few taps. These are great for simple, fast edits.
• If you want more control, like trimming clips, rearranging scenes, or adjusting speed, tap the Edit button. This tool opens up TikTok's timeline-style editor where you can fine-tune each part of your video.
• Once you're done with editing, tap Next.

Step 4Preview and finalize your video.

• In the preview window, you can write a caption, add hashtags, tag people, and choose a cover image.
• Click the More Options tool to adjust privacy settings and enable or disable comments and duets.
• When you're ready, tap Post to publish your video or Drafts to save it for later.

Method 2. Using a Third-Party Video Editor – Filmora for Mobile 

While native apps like CapCut offer great features, Filmora for Mobile goes further with AI-driven tools that save you time. Features like AI Captions and Smart Cutout are designed to give you a professional edge without complex manual work, making it the perfect alternative for creators who want more power than a simple editor offers.

Step 1Start a New Project and Import Your Videos

To adjust the speed, tap on the clip or click Trim and select the Speed tool.

• Select Normal for steady speed control, then slide the duration meter to make it faster or slower.

• To use this feature, go to Trim > Smart Cutout. Then, select the action you want: Replace Background, Customized Cutout, Replace Sky, or Chroma Key.
• Tap on the Checkmark icon to save the edits and wait for the result in a couple of minutes.

Step 5Add Automatic Captions or Subtitles with AI Captions Tool

You can also add subtitles using the AI Captions tool. It uses Speech-to-Text technology to convert the spoken audio in your video into subtitles that automatically sync with your voice.

• To use this feature, go to Text > AI Captions. Select the current language and adjust any other settings as needed. Then, tap Add Captions to start the process.

Step 6Final Touches and Export

• Add transitions between scenes if you want smoother flow, or overlay background music from Filmora's built-in library.
• Once you're happy with the edit, tap Export at the top right of your screen. Then, select the resolution, frame rate, and any other settings.
• Tap Export again to finalize and save your video. You can now upload it to TikTok manually or schedule it using TikTok's built-in tools.

Once you're done editing on your phone, you might want to try making videos on desktop too. Let's walk through how to create a TikTok video using a desktop video editor that offers deeper customization.
