Online Video Editor: AI Cutting, Subtitles and Motion Effects

You no longer need to install desktop software to make a video. video97 is a free AI video editor that works entirely in your browser. It can cut clips, add subtitles, generate voice-over, suggest music and turn still images into moving scenes. Here is a step by step workflow for your next short video, from uploading a raw file to exporting MP4.

Cut and trim your footage

Start by signing in at video97.com and clicking the New Project button. Drag your video file into the upload area, or use the import menu to pull from Google Drive or Dropbox. Once the file is in the timeline, you can play through it and find the sections you want to keep. Click the Split tool at the playhead to cut the clip into two parts. Select the part you do not want and press Delete. To trim the beginning or end, drag the edge of a clip inward. If your video is long, use the AI scene detection feature. It scans the footage and marks every scene change with a split point. You can then remove entire scenes without having to watch every frame. This is usually enough for a rough cut.

Add subtitles to video automatically

Subtitles are essential for social media, where most people watch without sound. With video97, you do not need to type timestamps. Click the Subtitles tab, then choose Transcribe with AI. The tool will listen to the audio in your video and create a subtitle for each sentence. You will see a list on the right side with the text and timing. Click any subtitle to correct spelling or change the timing. If you want a different caption style, open the Style panel. You can pick a white or yellow font, add a background box, and adjust the size. When your subtitles are ready, export them as an SRT file if you need them for another platform. For videos without speech, type the text manually and press Auto Sync, and video97 will align each line with your voice-over.

Generate a voice-over without a microphone

Not everyone has a good microphone or a quiet room. The AI voice-over tool in video97 produces a natural sounding narration from typed text. Click Voice-over in the left menu, then select a voice. There are dozens of options in different languages and accents. Adjust the speed and pitch if needed. Next, write your script in the text box, or paste notes that you have already prepared. Press Generate, and video97 will record a synthetic voice-over and place it on a new track. You can drag the audio block to align it with the visuals. If your original video has background noise, use the Speech Enhancer tool. It isolates the voice and removes hums and clicks. You can also lower the volume of the original audio so the voice-over is the only thing viewers hear.

Pick music and let AI match the pace

Music sets the mood, and video97 has a library of royalty free tracks built in. Use the search bar to filter by mood, such as upbeat, sad, or intense. You can also filter by duration to find a song that fits your video length. Once you drag a track onto the timeline, the AI can synchronize it with your cuts. Select the music clip, click Match Beats, and the tool will adjust where the cuts appear so they land on beats. You can do the opposite too, cut the music to fit your video. The auto ducking feature lowers the music volume automatically whenever a voice-over or subtitled speech is playing. That keeps dialogue clear without making the music disappear. Use the fade handles at the beginning and end of the music track to avoid abrupt starts and ends.

Make motion video from still images and text

Sometimes you only have a photo or a title card. You can still make a motion video with video97. Add an image to the timeline, select it, then click Motion. Choose Ken Burns to create a slow zoom in or zoom out across the image. The editor will animate the image over the duration you set. If the image is a subject, like a person or an animal, try the AI Animation option. It turns the still image into a moving sequence in which the subject moves slightly as if the photo were a video clip. That effect works best with clear, well lit images. For text, write a headline in the Text tab and pick an animation like Slide Up, Typewriter, or Fade. You can set the duration and starting position. Combine several animated images with text to build a complete slideshow without filming anything.

Export and share directly from the browser

When you are happy with the edit, hit the Export button. video97 renders the video in its cloud, so your browser does not have to do the heavy work. You can choose from 720p, 1080p, or 4K, depending on your plan. The free plan includes 720p output, which is enough for most web use. After the render finishes you will get a download link for an MP4 file. You can also share directly to YouTube, TikTok, or Instagram from the export screen. That is the full workflow: upload, cut, add AI subtitles, generate a voice-over, match music, animate a photo, and export. No file conversions, no codecs, no extra applications.

FAQ

Is video97 really free?

Yes. The free plan lets you edit and export videos up to a certain length, and it includes the AI tools in this guide. You get 720p exports and a watermark. For higher resolution and no watermark, you can upgrade to Pro, but the steps here work without paying.

Can I edit videos in the browser on a phone or tablet?

Absolutely. video97 runs in Safari, Chrome, and Firefox on both iOS and Android. You can cut clips, add subtitles, and export from a tablet or phone. The layout is optimized for touch, though a larger screen makes fine adjustments easier.

How long does it take to render a video?

It depends on the resolution and length. A short 30 second video at 720p usually takes under a minute. Longer videos can take a few minutes. Since the render happens in the cloud, you can switch tabs while it works. video97 will show a notification when the export is complete.
