You can describe a scene in natural language, provide a photo to animate, or generate a video complete with synchronized audio from an audio file or text-based dialogue description.

How does the character consistency feature work?

The feature utilizes the Omni Subject Library. When you define a character, the AI model locks its unique identifiers—such as facial structure, hairstyle, and key features—into a digital library.

In which languages does the lip-sync feature work?

The AI operates at the phoneme level, meaning it matches mouth shapes to the specific sounds in the generated dialogue, creating highly realistic and emotionally matched speech animation.

What is the maximum video length and quality?

The Kling 5.0 model can generate video clips up to 15 seconds in duration. All outputs are rendered in stunning 4K (3840 x 2160 pixels) resolution with professional cinematic quality, including realistic textures and accurate lighting, making it suitable for high-end commercial and broadcast applications.

How accurate is the AI transcription?

SubtitlesFast utilizes state-of-the-art, context-aware AI speech recognition models that deliver industry-leading accuracy for a wide range of accents and dialects. While accuracy is exceptionally high, the intuitive editor allows for instant manual corrections, ensuring perfect final results every time.

Do I need to download any software?

No. SubtitlesFast is a 100% cloud-native, browser-based application. You can access the full suite of features—from upload to export—directly from your web browser on any device, including your phone, with no installation required. Your video processing happens securely in the cloud.
