Frequently Asked Questions
Seedance 2.0 Fast supports true multi-modal input, allowing you to combine up to 9 images, 3 videos, and 3 audio files in a single generation. The intuitive @reference tagging system lets you specify exactly how each input should be used in your prompt, giving you unprecedented creative control over scene composition, motion, and audio synchronization that traditional text-only models cannot achieve.
When enabled, the model automatically generates synchronized audio that matches your video content, including sound effects, ambient sounds, and even lip-synced speech. This native audio capability eliminates the need for separate audio production workflows and ensures perfect synchronization between visual and audio elements, saving hours of post-production time while creating more cohesive, professional results.
You can upload up to 9 images (30MB each), 3 videos with a combined duration of 2-15 seconds (50MB total), and 3 audio files (15MB each, 15s combined duration). The total number of files across all modalities is limited to 12, and video references should be between 480p-720p resolution in MP4 or MOV format for optimal processing.
Seedance 2.0 Fast supports seven aspect ratios: 21:9 ultrawide, 16:9 widescreen, 4:3 standard, 1:1 square, 3:4 portrait, and 9:16 vertical, plus an auto mode that selects the best ratio based on your inputs. Resolution options include 480p for faster generation and 720p for balanced quality, making it suitable for social media, web content, and professional presentations.
Generation times typically range from 20 to 60 seconds depending on the complexity of your prompt, number of reference inputs, selected resolution, and video duration. The fast version is optimized for speed while maintaining quality, making it ideal for iterative workflows where you need to test multiple concepts quickly or produce content under tight deadlines.
Seedance 2.0 Fast is optimized for cost efficiency, typically consuming 30-40% fewer credits than the standard
Seedance 2.0 Reference to Video model while maintaining professional quality output. The exact credit cost varies based on your selected resolution, duration, and number of reference inputs, but a typical 5-second 720p generation with 2-3 references costs approximately 15-25 credits on the Fast version versus 25-40 credits on standard. For high-volume content creation where you need to generate dozens of videos for social media campaigns or client presentations, the Fast version's lower cost per generation can result in significant savings while still delivering results suitable for most professional applications. Check the credit display before each generation to see precise costs for your specific configuration.
Yes, all videos generated with paid credits on JAI Portal include full commercial-use rights, meaning you can use Seedance 2.0 Fast output for client projects, advertising campaigns, product demonstrations, social media marketing, YouTube monetization, and any other commercial application without additional licensing fees or attribution requirements. This applies whether you're a freelancer creating content for clients, an agency producing marketing materials, or a business generating internal promotional videos. The commercial rights are granted automatically with your credit purchase and cover unlimited distribution and reproduction of your generated videos. However, you remain responsible for ensuring your input materials—the reference images, videos, and audio you upload—have appropriate usage rights and don't infringe on others' intellectual property.
Seedance 2.0 Fast generates videos in MP4 format with H.264 codec, which provides excellent compatibility across all major platforms, browsers, and video editing software. The output files are optimized for web delivery with progressive download support, meaning they start playing before the entire file downloads. Audio is encoded in AAC format at 128kbps when audio generation is enabled, providing clear sound quality while maintaining reasonable file sizes. The generated MP4 files work seamlessly with Adobe Premiere, Final Cut Pro, DaVinci Resolve, and other professional editing tools if you need to incorporate them into larger projects. File sizes typically range from 2-8MB for 480p videos and 5-15MB for 720p videos depending on duration and content complexity, making them easy to download, share, and upload to social media platforms without compression issues.
To maintain character consistency across multiple videos, use the seed parameter to lock in successful character interpretations, then vary only the motion and scene elements in subsequent generations. Upload the same character reference image as @Image1 in each prompt while changing your text description and other reference materials to create different scenarios. For example, generate a base video of your character, note the seed value, then create variations by modifying @Video1 motion references or scene descriptions while keeping the seed and @Image1 constant. This approach works well for creating episodic content or multi-scene narratives. If you need even tighter character control for professional productions, consider
Kling O1 Reference to Video which offers advanced character consistency features, though at higher credit costs and slower generation times.
Motion artifacts typically occur when reference materials have conflicting characteristics—for example, mixing static product photos with fast-action video references or using low-resolution inputs. First, verify all reference images are sharp and well-lit, videos are stable (not handheld or shaky), and audio files are clean without distortion. Reduce the number of reference inputs if you're using the maximum—sometimes fewer, higher-quality references produce better results than many mediocre ones. Try regenerating with a different seed value, as some seeds produce cleaner motion than others. If artifacts persist, simplify your prompt to focus on one primary action or movement rather than describing multiple simultaneous motions. For complex scenes requiring precise motion control,
Google Veo 3.1 Reference-to-Video offers superior motion fidelity, though with longer generation times. You can also try the standard Seedance 2.0 version which allocates more processing power to motion coherence.
