I Tested Adobe Firefly AI Video Editing: 8 Features to Save You Hours

Last updated: September 2026 | Sponsored by Adobe

Author: Greg Preece — I test AI video tools hands-on and show creators how to get usable results fast.

If you create videos, you may have already heard of Adobe Firefly, Adobe's online generative AI platform. However, you might not know about the practical video editing features hidden inside its browser-based workspace. Adobe sponsored me to test these features hands-on to see if they can speed up your editing workflow and improve your production quality.

TL;DR: Adobe Firefly has evolved into a fully functional multi-model video editing workspace. By combining core timeline tools like automatic cut detection and audio enhancement with advanced partner models, you can edit footage, generate custom music, and create matching B-roll in a single tab.

Prefer to watch? Here's the video. Prefer to skim? The full breakdown is below.

1. Automatic Cut Detection (AI Scene Splitting)

When working with pre-edited video files or single long takes, manually cutting clips to make adjustments can eat up precious minutes. Adobe Firefly's timeline features a dedicated Detect Cuts tool that automates this entire process.

I tested this with a four-minute-long previously edited video featuring a mix of talking-head footage, B-roll, and screen recordings.

Caption: The AI-powered cut detection tool automatically segments your previously edited video into individual clips.

How to use Detect Cuts:

1. Import your pre-edited video or long clip into the Adobe Firefly timeline.
2. Right-click the video clip on your timeline track.
3. Select Detect Cuts from the dropdown menu.
4. Allow the AI a few seconds to scan the visual changes in the clip.
5. The timeline will automatically apply clean cuts at every transition point.

Once the AI finishes, you can immediately grab a transition effect and drag it directly onto the cut point, or select a segmented block (like an unwanted B-roll shot) and hit delete to remove it instantly.

2. One-Click Enhance Audio

Clean, clear voiceovers are critical to keeping viewers engaged. If you are forced to record with a microphone placed far away from you, your room acoustics can make the audio sound distant or hollow.

Firefly includes a browser-based version of the popular Enhance Audio tool found in Adobe Premiere Pro.

Caption: Turning on Enhance Audio automatically cleans up background noise and improves vocal clarity.

How to use Enhance Audio:

1. Select the audio or video clip in your timeline.
2. Open the Properties panel on the right side of the screen.
3. Scroll down to the audio settings and toggle on Enhance Audio.

The AI handles the heavy lifting, removing background hiss and treating the vocal frequencies without requiring you to manually balance EQ settings or noise gates.

3. Voice-Timed Sound Effects

Sound effects add weight to on-screen actions, but searching libraries and matching them frame-by-frame is tedious. Firefly resolves this by letting you generate custom sound effects using text prompts, with the option to mimic the exact timing using your own voice.

I tested this by generating "retro gaming gun sounds" for a short sequence where I acted out playing a game.

Caption: The Sound Effects tool lets you record your own vocal mimicry to perfectly align generated sound effects with your timeline.

How to use vocal-timed sound effects:

1. Cut the segment of video where you want the sound effects to occur.
2. Navigate to the Sound Effects generation tool in the workspace.
3. Type your prompt (e.g., "retro gaming gun sounds") and specify the duration.
4. Click the Record button and verbally mimic the rhythm (e.g., saying "pew pew") into your microphone.
5. Click Generate.
6. Firefly will map the generated sound effects directly to the waveform rhythm of your recording.
7. Click the generated audio clip to add it to your timeline and line it up with your video clip.

4. Prompt-to-Music Generation

Using stock music libraries can lead to licensing headaches or repetitive tracks. Firefly's audio tab features a dedicated music generator designed to build custom, royalty-free background tracks directly from text prompts.

I tested this by generating a "nostalgic song with a retro electronic style" to back my gaming segment.

Caption: The Audio workspace allows you to generate completely custom background music tracks based on descriptive prompts.

How to generate custom music tracks:

1. Head to the Audio section on the Firefly home panel.
2. Enter a descriptive prompt detailing the style, genre, and mood of the track.
3. Set your parameters, including Duration (e.g., 20 seconds), Tempo (Slow/Medium/Fast), and Energy (Low/Medium/High).
4. Click Generate and review the generated options.
5. Select your favorite track, download it, and import it into your active editing timeline.

5. Instant Video Audio Translation

Reaching global audiences typically requires hiring translators or voice actors. Firefly includes a native Translate Audio tool that automatically transcribes and re-voices your footage into other languages.

I uploaded a short clip of myself speaking English and asked the AI to translate it into Italian.

Caption: The audio translation tool automatically transcribes and translates your speech into other languages like Italian.

How to translate video audio:

1. Open the Translate Audio tool from the video tools section.
2. Upload your source clip. Firefly will automatically detect the spoken language and generate a text transcript.
3. Select your target language (e.g., Italian) from the dropdown list.
4. Click Generate and wait a few minutes for the translated audio track to compile.

While the AI voice does not currently align lip-syncing perfectly to the new translation, the spoken accuracy and overall tone matching make it a viable tool for quick international versioning.

6. Prompt-to-Edit Clip (Visual Alterations)

If you need to make drastic visual changes to an existing video file—like changing what a subject is wearing or swapping out an background element—the Prompt to Edit Clip feature is designed for exactly this.

I tested this by uploading a five-second clip of a man sitting in a chair and prompting the AI to change his outfit to a "clown suit."

Caption: The Prompt to Edit Clip panel lets you rewrite visual assets using advanced partner models like Luma Ray 3.14.

How to visually edit existing clips:

1. Navigate to the Firefly homepage and choose Prompt to Edit Clip.
2. Select your AI model. For this visual alteration, I used the Luma Ray 3.14 model integrated as a partner option.
3. Upload your original footage or use the workspace demo clips.
4. Enter your prompt explaining what visuals to alter (e.g., "replace the man's clothes with a clown outfit").
5. Press Generate and wait for the model to reconstruct the video frames.

The resulting video kept the movement of the original subject but successfully replaced the clothing, matching the lighting and even preserving the subtle color changes from the original shot.

7. Generating Custom B-Roll (Image-to-Video Workflow)

Creating engaging B-roll from scratch can be challenging. By using Firefly's multi-model integrations, you can generate a tailored reference image and then animate it using partner video models.

For my gaming scene, I wanted to generate a realistic five-second clip of a young boy playing a retro console in an 80s bedroom.

Caption: Creating a high-quality reference image first with partner models like GPT-Image-2.5 Flare provides a strong visual anchor for video generation.

Step 1: Create your reference image

1. On the Firefly homepage, navigate to the text-to-image workspace.
2. Select OpenAI GPT-Image-2.5 Flare as your active image model.
3. Upload an image of yourself to guide the subject's likeness if desired.
4. Prompt the tool (e.g., "a younger version of the man playing a retro games console in the 80s in his childhood bedroom").
5. Generate and download your preferred visual asset.

Step 2: Animate the image into video

1. Return to the Firefly homepage and select Generate Video.
2. Choose Kling 3.0 (or "Kling 3") from the partner models dropdown.
3. Upload the reference image you created in Step 1.
4. Set the target duration (e.g., 5 seconds).
5. Describe the desired motion in the prompt box (e.g., "the boy plays his retro games console in the 80s childhood bedroom").
6. Click Generate and wait for the render to complete.

Once rendered, the clip will be saved in your Generation History. From there, you can drag it straight onto your timeline to act as the perfect custom B-roll clip.

Caption: Uploading the reference image to the Kling 3.0 model lets you generate cinematic, matching B-roll footage in seconds.

8. Video Upscaler

Working with low-resolution archival footage or lower-quality AI video outputs can degrade the look of a modern edit. Firefly includes a native Upscale tool to sharpen your clips before exporting.

Caption: The built-in Upscale Video tool converts lower-resolution generations or imports into clean 1080p or 4K outputs.

How to upscale video in Firefly:

1. Navigate to the video section and select Prompt to Edit Clip.
2. Click the Upscale tool.
3. Import your target video clip.
4. Choose your desired output resolution under the settings menu (1080p or 4K).
5. Click Generate to render a sharpened, high-quality version of your footage.
