LTC Timecode Generator

The LTC Timecode Generator computes a sequence of LTC timecodes from a defined start timestamp, duration, and frame rate for use in video workflows. It targets editors, post-production staff, and broadcast engineers who need precise, frame-accurate references for logging, syncing, and cueing across cameras, audio recorders, and effects work. The tool models time as discrete frames and outputs a deterministic sequence that can be copied or archived for offline verification. It supports both non-drop-frame and drop-frame modes to align with standard broadcast conventions.

Conceptually, the generator advances by one frame per step, converts frames into HH:MM:SS:FF components, and formats each with leading zeros. For 29.97 DF, it applies standard drop-frame rules (skipping two timecode values at most minute boundaries except every 10th minute) to preserve real-time alignment. The result is a timecode array and a final end-timecode indicating sequence completion. Input validation checks ranges and prevents invalid configurations from calculation.

Typical workflows include logging, multi-camera synchronization, and pre-visualization planning where exact frame positions matter. Unique value lies in explicit DF handling, clean formatting, and an API-friendly output that supports batch generation and easy export to text or CSV for metadata records. The tool concentrates on planning and verification rather than live playback generation.
