How this service works
Slow-motion factor from capture and playback fps, output duration for real seconds, and capture fps needed.
Output
Returns the computed slow-motion factor (e.g. 5x), the playback duration in seconds for a given amount of real recorded action, the number of frames recorded, the speed as a percentage, and optionally the capture fps needed to achieve a desired slow factor — all alongside the echoed input parameters.
Example use cases
Pre-production slow-motion planning
“I want to achieve 8x slow motion on my 25fps timeline — what frame rate do I need to shoot at with my camera?”
Playback duration estimate for editor
“I shot 2 seconds of a splash at 240fps, and my project is 24fps — how long will that clip actually run in my timeline?”
Verifying slow factor from camera settings
“My camera records at 180fps and my playback timeline is 30fps — what slow-motion factor does that give me, and what percentage of real speed is it?”
Technical details
Endpoint
GEThttps://video-calc.x402tookit.com/slow-motion?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need precise mathematical slow-motion calculations for video production — specifically to determine slow factor from camera and timeline fps, estimate playback duration from real recorded seconds, or back-calculate the capture fps required for a target slow-motion effect. Prefer it over generic calculators when working with professional video frame rates and needing structured, machine-readable output including frames recorded and speed percentage.
Side effects
- Missing required captureFps parameter returns an error
- Non-numeric fps values cause validation failure
- playbackFps defaulting to 24 if not provided may produce unexpected results
- Extremely high or low fps values outside typical camera ranges may return degraded flag
- Providing both realSeconds and wantedSlowFactor simultaneously may cause ambiguous output
