Video generation & editing
Generation, subject annotations, mask refinement and transparent output.
Generate and inspect
Select a video model and review duration, aspect ratio, references and audio options. Inspect the actual returned video. Move the timeline to the frame you want to work on before annotating.
Matting workflow
Follow Generate mask → Refine → Update mask → Generate transparent video. Annotations and mask editing are separate. Moving between frames does not automatically run inference. Check complex movement, occlusion and cuts and add corrections where necessary.
Repaint video
Describe the changes and choose a repainting model that supports the required media inputs. Wait for tracking and generation. On failure, review the error and retry. Cloud generation cannot guarantee pixel-identical regions outside the edit.
Upscale and export
Video upscaling follows the source frame rate by default, with manual options where available. Transparent output needs an alpha-capable format such as the tool’s MOV output. A regular MP4 is not evidence of a successful transparent export.
