How this service works
2:3 pulldown cadence: which film frames land in which video fields and frames when 24 fps film is telecined.
Output
Returns a detailed breakdown of the 3:2 pulldown cadence including: a field sequence string (e.g. AABBBC), an array of video frame labels for each film frame, the total number of video frames and fields produced, a count of mixed frames (frames containing fields from two different film frames), the effective film and video fps after the 0.1% slowdown, and summary metadata.
Example use cases
Identify mixed frames before editing
“I'm editing telecined footage and need to know which video frames are mixed — can you map the 3:2 pulldown cadence for 60 film frames starting at phase 0 so I know which frames to flag?”
Reverse telecine planning for VFX
“I need to pull back 29.97 video to 24fps film. Can you show me the full pulldown sequence for 48 film frames starting on a 3-field frame so I know the field pattern to remove?”
Teaching telecine cadence to a student
“Can you lay out the 2:3 pulldown field sequence for just 10 film frames starting at phase 0, so I can see clearly how each film frame maps to video fields?”

Endpoint
GEThttps://video-calc.x402tookit.com/pulldown-32?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to understand or visualize the exact 3:2 pulldown cadence for a specific number of film frames — particularly useful for reverse telecine workflows, identifying mixed/interlaced frames in telecined footage, or teaching/documenting how 24fps film maps to 29.97fps NTSC video fields. Prefer this over manual calculation when you need per-frame field assignments rather than just a frame rate ratio.
Side effects
- filmFrames out of range (must be 1–240) returns validation error
- startPhase not 0 or 1 causes bad request
- Missing filmFrames query parameter returns error
- Payment failure or missing x402 header returns 402 Payment Required
