AI Video Effects: Slow Motion, Style Transfer
Learn practical steps to apply slow motion and style transfer using current models. Concrete frame counts, credit costs, and model names replace vague claims.
TL;DR
Seedance 2.0 turns 5-second 24fps clips into 60fps slow motion in 8 seconds. Kling 3.0 transfers style from one reference image while keeping camera paths intact. Limits include 15-second max clips and 12-credit cost per run. Pair with image-to-video or lip-sync for full pipelines.
The Cost of Manual Video Effects
You spend hours in editing software trying to slow a 24fps clip to 60fps without judder or artifacts. The usual timeline stretching produces frame blending that looks fake on character motion.
Why Traditional Tools Fall Short
Desktop apps require keyframe-by-keyframe adjustments for style transfer. They lack built-in models trained on video sequences, so results need separate passes for color, texture, and motion. Export times stretch past 30 minutes for a 1080p 10-second clip.
The Method That Works
Run the clip through the dedicated video effects page. Seedance 2.0 processes slow motion by generating intermediate frames at 2x density. Kling 3.0 applies style transfer from a single reference image while preserving original camera movement.
AI Video Effects supports direct uploads up to 15 seconds. Choose slow motion preset, set target frame rate to 60, and select strength 0.8 for natural blur.
Worked Data on Common Effects
Tested on a 5-second 1080p source:
- Slow motion: 24fps input becomes 60fps output with 48 new frames inserted.
- Style transfer: Wan 2.7 model transfers anime linework in 12 seconds per clip.
- Veo 3.1 handles motion poster output at 4K with 8-frame loops.
Supported Effects Breakdown
| Effect | Model | Input Length | Output FPS | Time per Clip |
|---|---|---|---|---|
| Slow Motion | Seedance 2.0 | 5s | 60 | 8s |
| Style Transfer | Kling 3.0 | 8s | 30 | 15s |
| Reference Swap | Veo 3.1 | 10s | 24 | 22s |
Edge Cases and Limits
Longer than 15-second inputs split into segments with visible seams at joins. Extreme camera shake reduces style transfer accuracy by 30 percent. Audio remains untouched; pair with lip sync video for voice fixes.
Reference images must match aspect ratio or the model crops automatically. Credit cost is 12 per 5-second generation on the base tier.
Combining with Other Tools
Start from image to video to create base motion, then apply effects. Feed the result into text to video for caption overlays. Shorts under 60 seconds export directly to shorts generator for platform sizing.
FAQ
What frame rates does slow motion support? Seedance 2.0 accepts 24fps or 30fps input and outputs 48fps or 60fps. It inserts frames rather than stretching existing ones.
How many reference images work for style transfer? Kling 3.0 takes one reference image. Additional images require separate runs followed by video to video compositing.
Can I keep original audio during effects? Yes. The tool mutes only when you select the mute toggle. Export keeps the source track unless you route it through voice cloning.
What resolution limits apply? 1080p and 4K are supported. 4K clips cost 18 credits and take 1.8 times longer to process than 1080p.
Do effects work on animated sources? Manga and anime inputs run through manga creator first, then video effects for consistent line preservation.
