Video duration converter

The tool converts video duration across formats used in editing workflows. It accepts inputs as hh:mm:ss, total seconds, or frames with a specified frame rate, and outputs equivalent values in all formats. Example: 02:15:30 equals 8130 seconds or 243,900 frames at 30 fps.
The engine normalizes all inputs to a base unit (seconds) and applies straightforward arithmetic. For timecode to frames, frames = (hours*3600 + minutes*60 + seconds) * fps. For frames to timecode, hours = floor(frames/(3600*fps)); minutes = floor((frames% (3600*fps))/ (60*fps)); seconds = (frames%fps)/fps. Sub-second precision is supported when inputs include decimals. The tool handles common fps values (24, 25, 29.97, 30, 50, 60) and validates that fps > 0.
Who benefits include editors, post‑production teams, and freelance creators who need accurate planning, scheduling, and cross‑format validation. Its unique value lies in handling both timecode and frame-based domains in a single calculation path, avoiding manual cross-checks, and offering precise rounding rules. Core features include multi‑mode input, bidirectional conversion, and clear numeric outputs. Typical use cases are aligning video segments, estimating render times, and preparing subtitles with exact timing.
Use cases span project planning, rapid comparisons between formats, and documentation of durations for reports or client reviews. The approach emphasizes correctness, reproducibility, and efficiency for media workflows while keeping calculations deterministic across common frame rates.
