Generative Extend overview

The Generative Extend tool, powered by Adobe Firefly, adds frames to the beginning or end of video and audio clips. Select and drag to seamlessly add a few more frames at the beginning or end of a video or audio clip—to hold on a character reaction for an extra beat, create a smoother transition, extend background sounds, or hide unwanted camera movement.

You can also use Generative Extend to create smoother transitions between clips that don't have enough media handles. When you apply a transition or adjust its duration, Generative Extend can generate the missing frames, eliminating the need to manually extend clips beforehand.

Generative Extend requires an internet connection because it uses a cloud-based AI model.

Media requirements

Video 

The following requirements apply to source media:

Video source media resolution:

• Minimum resolution: 360p (640 × 360 or 360 × 640)
• Maximum resolution: 4K UHD (4096 × 2160 or 2160 × 4096)
• Generative Extend supports landscape, portrait, square, ultra-wide, and custom aspect ratios.
• When your clip's resolution or aspect ratio doesn't match a natively supported configuration, extensions are automatically generated at the nearest higher supported resolution and reframed to match your source aspect ratio. Your original clip remains unchanged.

Interlaced and non-square pixel footage:

• Interlaced footage is now supported. Progressive extensions are generated.
• Footage with non-square pixel aspect ratios (such as anamorphic or broadcast SD formats) is now supported. Extensions are generated in square pixels. Your original clip remains unchanged in its native format.

Video source media frame rate and bit depth:

• Frame Rate: Source clips can be 12–60 fps, but extensions above 30 fps are generated at 30 fps.
• Bit Depth: Source clips can be 8-bit, 10-bit, or 16-bit, but extensions are generated in 8-bit.
• Color Space: Source clips can be SDR or HDR, but extensions are generated in SDR.
• Your original clip remains unchanged in its native format.

Audio

• Generative Extend cannot create or extend spoken dialog. During extension, existing dialog will be muted to preserve the integrity of the original speech content.
• Due to the complexity of musical structures and potential copyright concerns, clips containing music are not eligible for extension.
• Generative Extend supports only mono and stereo audio. Surround sound and 5.1 audio formats are not compatible with Generative Extend.

Managing generated content 

When you use Generative Extend, the AI-generated media is combined with your original clip to create a new clip in the Project panel. Each extension is saved as an H.264 MP4 or WAV file in the Captured and Generated scratch disk assigned in your project settings. Open Project Settings > Scratch Disks to specify a new location for your generated media, allowing you to manage your storage according to your workflow and space requirements. 

Ongoing development and limitations

Generative Extend is the first application of generative AI for editors inside video editing software. We know that many workflows require higher-quality outputs and robust turnover processes. In the coming months, we'll expand the range of media types that can benefit from Generative Extend, including formats and color space. We're also working on reviewing the advanced workflow to make passing projects to other creatives seamless. 

Some limitations are known in this iteration with the following features:

• Generative Extend can only be applied to the beginning or the end of a clip, not both.
• Speech to Text transcription, Text-Based Editing, and Captioning
• Media Intelligence
• Markers 
• Modify clip properties (Audio Channels, Color, Interpret Footage, Timecode) and speed adjustments
• Timecode and user-entered metadata 
• Interchange formats (XML, AAF, EDL, OMF) 
• Replace with After Effects Composition and Edit in Audition workflows 
• Multicam Source Sequences 
• Productions

Privacy and data usage 

Your media is never used to train Adobe's AI model. It's solely used to create the requested extension, ensuring your content remains private and under your control. Learn more about our generative AI commitments.
