How to Use Veo 4

Using Veo 4 is designed to be fast and intuitive, enabling anyone to generate compelling videos in minutes. Start by logging into your account and navigating to the dashboard, where you can choose between Text-to-Video and Image-to-Video workflows based on your creative input. To enable sound, select an audio-enabled model such as Veo 3 during setup. Craft a detailed prompt describing not only the scene but also any desired audio elements—like "a bustling city street at night with distant traffic hum" or specific lines of dialogue for characters to speak. You can enhance accuracy by uploading a reference image, applying negative prompts to filter out unwanted visuals, adjusting resolution up to 4K, and locking results with seed values for consistency.

Once your settings are configured, submit the generation request and track progress in real time through asynchronous processing. After completion, preview the video to ensure audiovisual alignment meets your standards before downloading the final file. Your dashboard stores all past projects, making it easy to revisit, edit, or re-generate content. For teams and developers, Veo 4 supports webhook integrations and multi-model access via Replicate, allowing scalable automation and optimized performance across large-scale content pipelines.
