Which Video Editing Tools Have AI Features?

Video editing tools with AI features now include most mainstream editors, among them VideoGen, CapCut, and Descript, so the useful question is which AI features save you the most time. The ones worth looking for are automatic captions, filler word and silence removal, text-to-speech voiceover, generated b-roll (images and clips), image to video, background music generation, natural-language edits, and aspect-ratio reframing. This roundup of AI video editing tools is organized by feature rather than brand, with a note on when a beginner should use each one and how it works in VideoGen.

Captions and transcript cleanup

What it does: the editor transcribes your audio, places caption lines on the timeline, and can remove filler words and silent pauses.

When a beginner should use it: always. Captions keep viewers watching with the sound off, and filler removal fixes the most common problem in a first on-camera take without any cutting skill.

In VideoGen: captions are generated from the voiceover or uploaded audio with 98%+ transcription accuracy. You pick an animated style, customize font, color, position, and animation, and export burned-in captions or an SRT or VTT file. Captions turn on for the whole project in one step. "Clean up transcript" removes filler words and silent pauses from every transcript in the project, with separate toggles for filler and pause removal, a shortest-pause setting, and a custom filler word list. It handles roughly three hours of speech in one pass, and the cuts stay editable on the timeline.

Voiceover and music

What it does: text-to-speech turns a script into a spoken voiceover. Music tools pick, upload, or generate a background track and let you set its volume.

When a beginner should use it: when you do not want to record your own voice, or when the script changes often. Re-generating a voiceover from an edited script is faster than re-recording. Use generated music when you have no licensed track ready.

In VideoGen: the voiceover step offers text-to-speech voices, including ElevenLabs and Inworld voices. For music, pick a track from the library, upload your own, or generate a background track from a text prompt, which VideoGen can write from your script. A generated track follows the duration you ask for, the volume is adjustable, and the track can be replaced at any time. It is background music, not a song-writing or vocal tool.

Generated visuals: b-roll and image to video

What it does: the editor generates still images or short clips from a prompt to cover a point in the script, and can animate a still image into a video clip.

When a beginner should use it: when you have a script but no footage. Generated b-roll fills the gaps between your on-camera or avatar scenes so the video is not one static shot.

In VideoGen: image generation supports text-to-image and image-to-image with reference images, and the results can be used as scene visuals. Video clip generation routes to a model from the quality tier you pick (Low, Standard, High, or Max). A single clip can run from 4 to 30 seconds on Seedance 2.5 and from 2 to 30 seconds on Wan 3.0; VideoGen never shortens a request to fit a model and instead moves to one that supports the length. The "Convert images to videos" action animates every eligible still image in the project, with an optional motion prompt, muted audio (recommended under a voiceover), and a quality tier. Stock footage and images are available when a real photo fits better.

Natural-language edits and reframing

What it does: you describe the change in plain words and the editor makes it. Reframing changes the aspect ratio of a finished project for another platform.

When a beginner should use it: from the first project. Describing an edit is easier than learning where every control lives, and reframing gives you a vertical version without starting over.

In VideoGen: an AI assistant inside the project makes edits from natural-language requests. "Remix actions" apply a polish step to a whole project in one request: enable captions, add transitions, set or generate background music, set a logo, convert images to video clips, clean up a transcript, or change the aspect ratio (16:9, 9:16, or 1:1). Each change lands on the timeline, and you can regenerate one scene without touching the rest.

How to pick an AI video editor as a beginner

1. Start from your input. If you have a script and no footage, pick a tool that generates visuals and voiceover. If you have footage, a tool that captions, cleans, and reframes may be enough.
2. Test on your own material. Caption accuracy, voice quality, and generated visuals vary with the content.
3. Check that AI output lands in an editable timeline. If you cannot move, trim, or replace what the AI made, you will redo the whole video when one scene misses.
4. Count the steps to a finished export. The fewer tools you move between, the faster you publish.

VideoGen covers all four from one script-to-video, voiceover-to-video, slideshow-to-video, or storyboard-to-video workflow in a desktop browser.

Frequently asked questions

Which AI video editing tools are best for beginners?

Pick a tool where AI output lands in an editable timeline and where captions, voiceover, and reframing need one step each. Test it on a short piece of your own content before you commit.

Which AI video editor should I use if I have a script but no footage?

Use a tool that generates both the voiceover and the visuals from the script. VideoGen's script-to-video workflow adds a text-to-speech voiceover, generated images and clips, captions, and music to one timeline, and you can add real footage, screen recordings, or stock later.

Can an AI video editor remove filler words from a talking-head recording without leaving jump cuts?

The cuts are invisible on voiceover and b-roll, but on a single on-camera shot each removed word is a small jump cut. In VideoGen the cuts stay editable, so you can restore a word or cover a noticeable cut with b-roll or a different scene.

Will AI edits lock me out of manual changes on the timeline?

Not in VideoGen. Every AI edit, including remix actions that change the whole project, lands on the timeline where you can move, trim, or replace it.
