Video-to-audio in four simple steps
Simple enough for creators, structured enough for a real production pipeline.
Upload video or paste URL
Start with MP4/MOV/WebM or a video link. The interface makes the video-to-audio job obvious above the fold.
Describe + exclude sounds
Use prompt and negative prompt to guide what should appear and what must be avoided.
Tune generation settings
Choose model, duration, mood, intensity, and output type before spending credits.
Generate and export
Create a real PiAPI MMAudio task, preview generated media, and download the output when ready.
Reference optimization
What changed from the MMAudio reference
The goal is not to copy. It is to steal the conversion logic: clarity, specificity, controls, examples, process.
Reference pattern: generator first
MMAudio puts the tool directly in the hero. SonicForge keeps that conversion logic but routes users into a cleaner upload → task → output flow.
Reference pattern: video/audio specificity
The copy now leads with silent video → synchronized audio, not generic “AI sound effects.”
Reference gap: trust details
The competitor is strong on broad claims but weak on operational detail. SonicForge shows file limits, task states, cost estimate, prompts, negative prompts, and output handling.

FAQ
Reduce doubt before launch
How does SonicForge generate audio for videos?
Upload MP4, MOV, or WebM — or paste a public video URL. SonicForge stores the file, creates a PiAPI MMAudio video-to-audio task, then returns generated media for preview/download.
Can I use a prompt without uploading video?
Yes. You can start from text-only sound effects, ambience, brand stings, or video-scene descriptions.
Why include a negative prompt?
It lets users remove unwanted vocals, music, clipping, distortion, or distracting noise — a key control for better generation quality.
What should happen next?
The generation pipeline is live for controlled preview. Before paid traffic, the next layer is login, credits, domain, and analytics storage beyond Worker logs.
