Features

Video Script Duration Splitter is a free browser tool for short-video creators, live-read hosts, video directors, and editors: paste a whole voiceover script (Chinese, English, numbers), set either a target total duration in seconds or a WPM speech pace, and the tool auto-splits the script into dozens of small clauses by punctuation + natural speech pauses, giving each clause an estimated duration, cumulative timestamps, and exports you can drop straight into JianYing / CapCut / Premiere for subtitle alignment or as a teleprompter shot list.

When You Need This

Common pain points this tool solves

1. A Douyin creator writes a 2-minute product-hype voiceover of 420 Chinese characters, sets 120 seconds target duration, and the splitter cuts it into 36 clauses with 1.5–4 second estimates each. Imported into CapCut, every subtitle line lands right next to its corresponding shot change, no manual timeline dragging line by line.
2. A course lecturer writes an 8-minute script and wants to record screen capture in ~20-second chunks. Splitter segments into 18–22 second blocks, each stamped with cumulative timestamp, so if one take flubs the lecturer only re-records that 20-second block, not the whole 8 minutes.
3. A brand-film director receives a client's 3-minute narration script that must match 2–4 second visual shots. Splitter cuts into short clauses by punctuation, giving each line a precise duration budget, so the shot list can be lined up line-by-line without narration running long past each cut.

How to Use

Step-by-step instructions

1. Paste the full voiceover / narration script into the main input. Chinese, English, numbers, common punctuation all work; blank lines and line breaks are auto-recognized as paragraph separators.
2. Choose a split strategy: auto-even by target total duration (seconds), or manual WPM speech pace (Chinese common 180–240 chars/min, English 130–160 words/min). You can also add extra per-clause pause milliseconds.
3. Inspect the results table: each clause shows original text, character/word count, estimated seconds, cumulative start/end timestamps, and paragraph membership. Drag or manually override any single clause's duration if you disagree.
4. Pick an export format: JianYing / CapCut subtitle SRT or VTT (one clause per time slice), teleprompter shot list (plain text timestamp list), or Premiere-compatible XML that drops straight into an NLE subtitle track.

Why Choose Korelyy

What makes us better

1. Supports both real production workflows in one tool: fixed-total-duration split (used heavily by short-video creators: 'I need exactly 60 seconds no more') and WPM-based split (used by lecturers / podcasters: 'I speak 210 chars/min, follow that'). No need to maintain separate Excel formulas for each.
2. Chinese clause splitting uses punctuation + speech pause logic (commas, periods, logical connectors like 于是 / 所以 / 但是), not mechanical per-character slicing, so each clause is a natural breath-unit for oral delivery — never a mid-phrase hard cut at character 17.
3. Export formats cover the editorial pipeline: SRT, VTT, plain-text subtitle lists that JianYing / CapCut import directly, plus Premiere XML and EDL-compatible output DaVinci Resolve reads natively. Compatible with mainstream editing and subtitle software, no manual timeline tuning required up front.
