Frame interpolation can double your video frame rate and eliminate stutter without spending extra generation credits. Instead of regenerating at a higher frame rate, synthesize intermediate frames using motion vector estimation.
We published a hands-on note explaining when to use interpolation (slow-motion product shots, camera movement smoothing, extending short clips) and common pitfalls like ghosting artifacts in fast-motion scenes. The article is on the blog index for all three site languages. Questions or feedback: sapsap@qq.com.
