Why Edit Videos in the Browser with AI?

Traditional video editing software is powerful, but it often requires a fast computer, a large download, and hours of learning. Browser-based editors remove those barriers. You can open video97 on any device with an internet connection and start editing immediately. The AI features are the real game-changers. Instead of manually scrubbing through footage to find the good parts, the AI can detect silences, pauses, and mistakes. Instead of typing subtitles by hand, the AI transcribes speech in seconds. Instead of creating complex animations frame by frame, you can apply motion presets with a click. This makes video editing accessible to everyone, from beginner creators to experienced marketers.

Step 1: Upload Your Footage to the Online Video Editor

Open video97 in your browser. The interface is clean and minimal, so you will not feel lost. To start a new project, click the "New project" button. Then, upload your video file. The online video editor supports common formats like MP4, MOV, and WebM. You can also drag and drop files directly into the workspace. If you have multiple clips, you can upload them all and arrange them on the timeline later. Once the upload is complete, the video appears in the preview window and on the timeline. You can play it, pause it, and move the playhead to any frame. This is your workspace for the rest of the edit.

Step 2: Cut and Trim with AI Assistance

The first task is to remove the parts that do not add value. video97 includes an AI-powered cutting tool that can analyze your footage and suggest cuts. Here is how to use it:

1. Click the "Cut" tool in the toolbar.
2. Choose "Auto-cut" from the options.
3. Set the sensitivity. For example, you can tell the AI to remove silences longer than 0.5 seconds.
4. The AI will scan the video and mark the sections it recommends removing.
5. Review the suggestions. You can accept all, or click on each one to decide individually.
6. After applying the cuts, the video is automatically reconnected, and the timeline is updated.

For manual trimming, drag the edges of a clip on the timeline. This is useful when you want to remove a specific moment, like a cough or a long pause. You can also split a clip at the playhead position and delete the unwanted section. The AI is especially helpful for talking-head videos, where jump cuts are common. You can set the AI to remove filler words like "um" and "uh" if the speech recognition detects them.

Step 3: Add Subtitles to Video Automatically

Subtitles are essential for engagement, especially on social media. Many people watch videos without sound, so clear subtitles keep them watching. With video97, you can add subtitles to video automatically. Here is the process:

1. Click the "Subtitles" button in the toolbar.
2. Select "Auto-generate".
3. Choose the language of the speech, or let the AI detect it.
4. The AI transcribes the audio and creates a subtitle track with timestamps.
5. Review the subtitles in the preview window. If there are any errors, click on a subtitle block and edit the text.
6. Customize the style: font, size, color, background, and position. You can also add a text outline or shadow for better readability.
7. Adjust the timing by dragging the subtitle blocks on the timeline.

The AI supports many languages, including English, Spanish, French, German, and Portuguese. If your video has multiple speakers, the AI will still generate a single subtitle track. You can also upload your own subtitle file if you prefer to create them manually. But the automatic option is much faster and usually accurate enough with minor edits.

Step 4: Make Motion Video with Effects

A static video can feel flat. Motion graphics add energy and help tell your story. In video97, you can make motion video by applying motion presets to any clip. Here are some ways to use motion:

• Ken Burns effect: slowly zoom in or out on a photo or video clip. This is great for adding life to still images.
• Text animations: animate your titles and captions. You can make text slide in, fade, or bounce.
• Shape overlays: add arrows, circles, or boxes to highlight important parts of the screen.
• Camera movement: simulate a pan or tilt by setting start and end positions for the clip.

To apply motion, select a clip on the timeline and click the "Motion" tab. Choose a preset from the library. Each preset has adjustable parameters, such as speed, direction, and intensity. You can also create custom motion by adding keyframes. For example, you can move a text layer from the left to the right over two seconds. The AI can also generate motion from a single image. If you have a product photo, you can turn it into a short video with a subtle zoom and pan. This is perfect for making promo videos or social media posts.

Step 5: Add Voice-Over and Music

Audio is half of the video experience. video97 makes it easy to add both voice-over and background music. To add a voice-over:

1. Click the "Voice-over" button.
2. Type your script or paste it from a text file.
3. Choose a voice from the available options. You can listen to a preview before selecting.
4. Adjust the speed and pitch if needed.
5. Click "Generate". The AI will create an audio file and place it on the timeline.

You can also record your own voice directly in the browser using your microphone. For background music, the editor includes a library of royalty-free tracks. Browse by mood, genre, or duration. Drag a track onto the audio timeline. The AI can automatically duck the music when the voice-over is playing. This means the music volume lowers during speech and returns to normal in between. This ensures your narration is always clear.

Step 6: Export and Share

Once your video is edited, it is time to export. Click the "Export" button in the top right corner. Choose the resolution: 720p, 1080p, or 4K. Select the frame rate, usually 30 or 60 fps. You can also choose the video quality, which affects the file size. video97 renders the video in the browser, so you do not need to install anything. The render time depends on the length and complexity of your video, but it is usually quick. When the export is complete, you can download the MP4 file. You can also share it directly to platforms like YouTube, TikTok, or Instagram if you have connected your accounts. If you need to make changes later, you can save the project and return to it anytime.
