Generate soundtracks for your uploaded videos in a few simple steps.
With Generating soundtrack (beta), you can upload a video to receive a tailored prompt based on its content, such as vibe, style, purpose, energy, and tempo. You can then customize and refine the prompt to better match your needs.
On the Generate soundtrack page, the left panel contains a sample prompt. The colored text in the prompt represents a structure that highlights different dimensions of soundtrack generation.
A. Vibe B. Non-customizable part of the prompt C. Style D. Purpose
To generate a soundtrack for your video, upload the video using the Upload Video option.
The video is analyzed, and based on its attributes, you get a starting point for your prompt, which you can edit and customize before beginning the soundtrack generation process.
Note
When using Firefly on a mobile device to upload a video, it must be in MOV or MP4 format, under 100 MB in size, and no longer than 5 minutes.
If you want to edit the prompt, you can refine it further by removing or adding the preloaded tags for each attribute.
You can edit the prompt by selecting tags from the following available attributes:
- Vibe: Represented by purple text in the prompt. You can use this to define the overall mood or emotional tone for soundtrack generation.
- Style: Represented by blue text in the prompt. You can use this to define the genre or instrumentation for soundtrack generation.
- Purpose: Represented by green text in the prompt. You can use this to define the intended use case or context for soundtrack generation.
If you want to add your own tags for any of the attributes, you can use descriptive adjectives.
Set the energy of the soundtrack by choosing from the following options:
- Low: Soft and calm
- Medium: Balanced with a steady rhythm
- High: Fast and lively
Set the tempo to define the speed or pace of the soundtrack for the generation. There are the following options to choose from:
- Slow: Low-paced and calm
- Medium: Steady, balanced, and moderately paced
- Fast: Quick, energetic, and high-paced
By default, the duration of the generated soundtrack will match the duration of the uploaded video. If you want to increase or decrease the duration, you can use the Duration section.
Select Generate to trigger the soundtrack generation.
You can use the credits indicator next to the Generate button to check how many generative credits will be used.
Once the soundtrack is generated, you'll get four different variations. You can preview each one along with the video.
Highlight the variation that you want to download and select Download.
The file is downloaded in the same format (MOV or MP4) as the one you uploaded.
Tip
If your soundtrack isn’t matching your expectations, it may be due to conflicting input terms. For example, setting the Vibe to calm and the Style to heavy metal can lead to unpredictable results, often favoring one over the other.
You can adjust the Vibe to better align with your desired mood, then refine the Style to complement it, and avoid mixing terms that represent opposite emotional tones or musical genres.
