Scenario has a large suite of video generation models available and knowing/selecting the right one for your specific needs can significantly impact the quality and effectiveness of your results. This guide will help you understand the key factors to consider when choosing a video generation model.
Understanding Model Categories
Scenario's video generation models fall into several categories, each with distinct characteristics and strengths:
By Input Type
Text-to-Video (T2V) Models: These models generate videos based solely on text descriptions, offering maximum creative flexibility when you don't have a reference image.
Image-to-Video (I2V) Models: These models animate existing images, maintaining the visual style and composition of your original artwork while adding natural movement. Some models support only the first frame as input, while others allow both the first and last frames for greater control.
“Hybrid” Models: These models support both text and image input, offering greater versatility and control. They are the most common models on Scenario and widely used in the industry because they provide more control options for better consistency in results.
By Specialization
General-Purpose Models: Versatile models that perform well across a wide range of content types and styles. Top choices include Kling 2.6 (Pro), Veo 3.1, and Sora 2.
Specialized Models: These models are tailored for specific content types, such as character animation or natural scenes, or distinct visual styles like cinematic or anime. Examples of models in this category include Minimax Hailuo 2.3 and Wan 2.5, or Ray 2 for cinematic scenes.
Video Editing Models: Designed to modify, enhance, or transform existing footage rather than generating from scratch. They excel at editing tasks and transformations. Leading examples include Lucy Edit (Pro) and Kling 01 Video Editing.
By Resolution
Medium Definition (480p) Models optimized for faster generation and lower resource requirements, suitable for quick iterations and concept testing. Example: Seedance 1(Pro Fast).
High Definition (720p+) Models that balance quality and performance, ideal for most professional applications and social media content. Example: Minimax Hailuo 2.3.
Full HD (1080p+) Premium models that produce the highest quality output, perfect for showcase pieces and professional productions. Example: Sora 2 (Pro), Kling 2.6 (Pro) or Veo 3.1.
Other Settings
Additional settings include customizable video duration, aspect ratio options, frame rate settings, effects, and more. These can be adjusted in the “settings“ tab (typically found in the bottom left corner of the video generation interface) to adjust your video generation inferences.
Key Factors to Consider
When selecting a video generation model, consider these important factors:
1. Visual Quality
Different models produce varying levels of visual fidelity, detail, and aesthetic appeal:
Resolution: Higher resolution models (720p, 1080p) provide more detail but may require longer processing times.
Detail Preservation: Some models excel at maintaining fine details throughout the video.
Visual Coherence: Better models maintain consistent visual elements across frames without flickering or distortion.
2. Motion Quality
The naturalness and smoothness of movement varies significantly between models:
Physics Accuracy: How realistically the model simulates natural movement and physical interactions.
Camera Movement: Some models specialize in cinematic camera techniques like panning, zooming, and tracking shots.
Motion Control: The degree to which you can specify and control movement through prompts.
3. Style Compatibility
Consider how well a model aligns with your desired aesthetic:
Artistic Styles: Some models excel at specific visual styles (photorealistic, animated, stylized, etc.).
Subject Matter: Certain models perform better with particular subjects (people, landscapes, products, etc.).
Mood and Atmosphere: Models vary in their ability to capture specific emotional tones or atmospheric conditions.
4. Technical Specifications
Practical considerations that affect workflow and output:
Video Duration: Models typically generate between 2-12 seconds of footage.
Frame Rate: Higher frame rates (24-30fps) produce smoother motion.
Generation Time: Processing times range from 30 seconds to several minutes per video.
Aspect Ratio: Available options typically include 16:9 (landscape), 9:16 (vertical), and 1:1 (square), and more (including custom ratios)
5. Prompt Responsiveness
How well the model follows and interprets your instructions:
Prompt Adherence: Some models follow detailed instructions more accurately than others.
Text Handling: The ability to generate or maintain readable text within videos.
Specific Direction: How well the model responds to precise movement or camera instructions.

Decision-Making Process
You may follow these steps to select the most appropriate model for your project:
Define your primary goal
Consider what you're creating, who it's for, and where it will be displayed. Understanding your project's purpose helps narrow down model options based on their strengths.
Identify your input resources
Determine if you'll work with reference images or text-only prompts, and assess how detailed your concept or reference material is. This will guide you toward either I2V or T2V models.
Determine technical requirements
Decide on the resolution, duration, and aspect ratio needed for your intended platform or display context. Different models offer varying capabilities in these areas.
Consider style and subject matter
Think about your desired visual style, main subject, and the type of movement or action involved. Some models excel with specific styles or subjects.
Evaluate practical constraints
Consider how quickly you need results and whether you're in the concept development or final production stage of your project.
Conclusion
Selecting the right video model is an important step in creating effective AI-generated video content. Understanding the strengths and specializations of different models and matching them to your specific needs will improve your results and workflow efficiency.
Remember that experimentation is often necessary, so try testing different models with the same prompt or input image to discover which one best aligns with your creative vision. As you gain experience, you'll develop intuition for which models excel at particular tasks and styles.
