FAQ

Common questions about Gen4 Aleph (Video Edit)

Read the docs

Gen4 Aleph is an in-context video editing model designed for post-production tasks like object removal, relighting, VFX addition, camera angle generation, and environmental changes. It transforms existing footage via text prompts without regenerating scenes from scratch.

Unlike models that generate video from text or images, Gen4 Aleph enhances real footage by understanding scene context—lighting, spatial arrangement, object relationships—before applying edits. This ensures coherent, realistic results integrated seamlessly with original footage.

Gen4 Aleph processes input videos up to 16MB, using the first 5 seconds for generation. It supports multiple aspect ratios: 16:9, 9:16, 1:1, 4:3, and 3:4 for platform versatility.

Yes, Gen4 Aleph accepts up to three reference images to guide the style, mood, or content of the output, enabling more precise creative control over transformations.

Gen4 Aleph delivers high-quality video edits in 60-120 seconds, making it ideal for rapid prototyping and quick turnaround workflows in production environments.

The Gen4 Aleph API enables object manipulation, scene generation, environmental changes, camera angle generation, relighting, VFX insertion, and weather/season modifications—all controlled through detailed text prompts.
