三个聚焦模式
第一版先做窄一点：一个上传流程，三个高意图输出。
Canvas Extension
Expand a clip into vertical, square, or widescreen placements without rebuilding the whole scene by hand.
Duration Extension
Turn short footage into longer motion assets using interpolation and transition-aware timing.
Seamless Loops
Generate a bridge from the end back to the beginning so the video can repeat cleanly.
MVP 最佳工作方式
上传一个视频，选择一个延展模式，确认结果，然后下载。
Upload one short MP4 clip.
Choose canvas extension, duration extension, or loop mode.
Review the generated preview and download the best result.
Start usage-based, not plan-heavy
The first version only needs one simple commercial model: charge per processed clip, keep credits transparent, and learn which extension mode is worth scaling.
常见问题
Which mode is best for the first launch?
Duration extension is usually the fastest path. It is easier to explain, cheaper to validate, and less fragile than full outpainting.
Why keep everything under one domain?
All three tools are forms of video extension, so one brand keeps positioning simple while you learn what converts.
Should the first version be self-hosted?
No. Hosted inference is the practical start. Move hot paths to your own GPU stack after demand is clear.
