Video Speed Adjustment

视频速度调整

Adjust video playback speed using each::sense. This skill enables speed manipulation for creative effects including slow motion, time-lapse, hyperlapse, speed ramping, reverse playback, and frame interpolation for ultra-smooth slow-mo.

借助each::sense调整视频播放速度。该技能可实现多种创意效果的速度操控，包括慢动作、延时摄影、移动延时摄影、变速渐变、倒放，以及通过帧插值实现超流畅慢动作。

Features

Best Practices

最佳实践

Slow Motion

慢动作

Source Frame Rate: Higher source FPS (60fps, 120fps) produces better slow motion
Frame Interpolation: Use AI interpolation for smooth results from 30fps sources
Output FPS: Request 60fps output for smooth playback on modern displays
Avoid Extreme Slow-Mo: Going below 0.25x may produce artifacts

源帧率: 更高的源帧率（60fps、120fps）能生成更好的慢动作效果
帧插值: 针对30fps源素材，使用AI插值实现流畅效果
输出帧率: 请求60fps输出，适配现代显示器的流畅播放需求
避免极致慢动作: 速度低于0.25x可能产生画面失真

Speed Up / Time-Lapse

加速/延时摄影

Audio Handling: Remove audio for extreme speed-ups (4x+) or use pitch correction
Motion Blur: Add slight motion blur for smoother fast-forward appearance
Stabilization: Apply stabilization for handheld footage before speed-up

音频处理: 大幅加速（4x及以上）时建议移除音频，或使用音调校正
运动模糊: 添加轻微运动模糊，提升快进画面的流畅感
画面稳定: 加速前先对手持素材进行稳定处理

Speed Ramps

变速渐变

Smooth Transitions: Request gradual speed changes over 0.5-2 seconds
Mark Key Moments: Describe which parts should be slow vs fast
Audio Sync: Consider how speed changes affect audio/music sync

平滑过渡: 请求在0.5-2秒内实现渐进式速度变化
标记关键时刻: 明确描述哪些片段需要慢放、哪些需要加速
音频同步: 考虑速度变化对音频/音乐同步的影响

Prompt Tips for Speed Adjustment

速度调整提示词技巧

When requesting speed adjustments, include these details:

Speed Factor: Specify exact multiplier (0.5x, 2x, 10x)
Frame Interpolation: Request if needed for smooth slow motion
Output FPS: Specify desired frame rate (30fps, 60fps, 120fps)
Audio Handling: Keep, remove, pitch correct, or reverse
Transitions: For speed ramps, describe how transitions should feel
Quality Priority: Mention if smoothness or detail is more important

请求速度调整时，需包含以下细节：

速度系数: 指定精确的倍数（0.5x、2x、10x）
帧插值: 说明是否需要帧插值以实现流畅慢动作
输出帧率: 指定期望的帧率（30fps、60fps、120fps）
音频处理: 保留、移除、音调校正或倒放音频
过渡效果: 针对变速渐变，描述过渡的感受
质量优先级: 说明更看重流畅度还是细节

Example Prompt Structure

提示词结构示例

"[Speed effect] this video to [speed factor].
[Frame interpolation requirement].
Output at [fps] for [use case].
[Audio handling instruction].
[Additional quality requirements]."

"为该视频添加[速度效果]，速度系数为[速度倍数]。
[帧插值需求]。
输出帧率为[fps]，用于[使用场景]。
[音频处理说明]。
[额外质量要求]。"

Error Handling

错误处理

Error	Cause	Solution
`Failed to create prediction: HTTP 422`	Insufficient balance	Top up at eachlabs.ai
Timeout	Long video processing	Set client timeout to minimum 10 minutes
Choppy slow motion	No frame interpolation	Request AI frame interpolation
Audio pitch issues	Speed change without correction	Request pitch correction or remove audio

错误	原因	解决方案
`Failed to create prediction: HTTP 422`	余额不足	在eachlabs.ai充值
超时	视频处理时长过长	将客户端超时设置为至少10分钟
慢动作卡顿	未使用帧插值	请求AI帧插值
音频音调异常	速度变化未进行校正	请求音调校正或移除音频

Technical Notes

技术说明

Client Timeout: Set HTTP client timeout to minimum 10 minutes for video processing
Video Length: Longer videos take proportionally more time to process
Frame Interpolation: Adds processing time but dramatically improves slow motion quality
Maximum Speed: Practical range is 0.1x to 20x depending on source footage

客户端超时: 将HTTP客户端超时设置为至少10分钟，以适配视频处理需求
视频长度: 视频越长，处理时间相应越长
帧插值: 会增加处理时间，但能显著提升慢动作质量
最大速度范围: 根据源素材，实际适用范围为0.1x到20x
