Introduction
Pencil offers access to a growing set of advanced Video Generation models that help you bring ideas to life through motion. These tools are well suited for creating short-form video content, animatics, and visual sequences - especially when combined with reference frames, style inputs, or prompts grounded in your Brand Library.
Some of the use cases include:
Generating video from a text prompt to visualise campaign ideas
Creating short-form video assets for social or ad formats
Sequencing still images into motion-based storyboards or animatics
Experimenting with motion-first storytelling for conceptual work
Producing short, repeatable motion clips for use in branded content or concept tests

Brief Comparison
Video generation is a fast-moving space, and each model supported in Pencil brings different strengths depending on the type of content you’re creating.
High-quality, cinematic motion: Models like Runway Gen-4 Turbo and Google Veo2 tend to excel at more refined video output - often better suited to realistic scenes, human figures, and smoother motion.
Fast, expressive outputs: Runway Gen-3 Turbo is often used for quick ideation and stylistic variation—particularly when the goal is visual exploration rather than polished final assets.
Stylised or frame-based motion: Stable Video is well suited to more interpretive or creative outputs, especially when working from a sequence of still images or abstract prompts.
Support for Start & End Frames: Some Image to Video Models support Start Frames, End Frames or Both:
Start Frame Only Support:
Stable Video

Summary
Results can vary based on input format (text, image, or frame sequence), model selection, and prompt structure. We recommend testing a few different models to find the best fit for your intended tone, pacing, and level of realism.
When working from reference frames or brand-aligned visuals, model choice is just one factor to consider. Prompt structure, frame sequencing, and visual context often have equal or greater influence on the final result.
