Adobe has launched the latest version of its video editing program, Premiere Pro. Version 25.2 of Premiere Pro adds a new AI-powered tool called Generative Extend.
Generative Extend
The new Generative Extend feature in Premiere Pro uses the power of Adobe Firefly generative AI. You can use the tool to extend your video clips by up to two seconds and audio clips by up to 10 seconds. Generative Extend can also be applied to the beginning or end of a media clip. However, you can’t extend both ends of the same clip. Also, you will need to have an internet connection, as Generative Extend utilizes a cloud-based AI model.
How it works
First, you need to select the clip in your sequence that you want to extend. Your original video clips need to be at least 2 seconds long, and audio clips need to be at least 3 seconds long. Next, you select the Generative Extend tool in Premiere Pro’s toolbar. You can then select your video or audio clip and drag the edge to the length you need. Once created, the AI-generated frames are clearly labelled. If you aren’t happy with the results, you can right-click on the AI-generated label and select Regenerate for a new variation.
In addition, you can right-click on the AI-generated label and select Revert to Original to go back to your original media.
Media requirements for video
Currently, Generative Extend only works with certain video resolutions. These are:
- 1920×1080 or 1080×1920
- 720×1280 or 1280×720
- 3840×2160 or 2160×3840
- 4096×2160 or 2160×4096
You can’t extend other resolution video clips, even if they have been scaled in a sequence. Clips also must have a frame rate between 12–30 fps. They are also limited to 8-bit SDR formats. Each video extension is saved as an H.264 MP4 file.
Audio clip requirements
Generative Extend can’t create or extend spoken dialog. During extension, existing dialog will be muted to preserve the integrity of the original speech content. You also can’t extend clips containing music. Adobe says that this is due to the complexity of musical structures and potential copyright concern. Additionally, Generative Extend only supports mono and stereo audio clips. Surround sound and 5.1 audio formats are not currently compatible with the feature. Extended audio clips are saved as .wav files.
What we think
The new Generative Extend tool in Premiere Pro has a lot of promise. There are so many situations when you might wish you had a slightly longer clip once you get to the edit. Maybe you wish you had held on to a person’s reaction for a moment longer. There are also times when the additional frames needed for a transition expose a camera movement that you wish wasn’t there.
Now with Adobe’s Generative Extend, you can create those extra frames in post-production. It’s also another great application of AI that doesn’t impact on anyone’s job. We wait to see how good the results are with the first version of the Generative Extend feature, but it will only get better with future revisions.
Pricing and availability
Version 25.2 of Premiere Pro with Generative Extend is available to download from the Adobe Creative Cloud now.
