csSimple Audio/Video Timing Tool: Feature Overview & Time-Saving Tricks

csSimple Audio/Video Timing Tool — Quick Start Guide

What it is

csSimple Audio/Video Timing Tool is a lightweight utility for creating, editing, and exporting precise timing data for audio and video projects (subtitles, cut lists, markers). It focuses on simplicity and fast manual adjustments.

Key features

• Timeline-based editing: Drag-and-drop start/end points and markers.
• Frame-accurate controls: Set times by hh:mm:ss:ff or milliseconds.
• Multiple export formats: SRT, VTT, CSV, EDL, and simple JSON.
• Batch adjust: Shift or scale groups of timings by absolute amounts or percentages.
• Search & replace metadata: Edit tags or labels across many entries.
• Undo/redo & autosave: Keeps work safe during rapid edits.

Quick setup

1. Install the app or open the web tool (assume default settings).
2. Import media (audio/video) or load an existing timing file.
3. Choose project frame rate (e.g., 24, 25, 29.97) so frame numbers match.
4. Save project immediately to enable autosave/versioning.

Basic workflow (step-by-step)

1. Import your media or timing file.
2. Create a new cue/segment with the Add button or by pressing Enter on the timeline.
3. Move the playhead to the desired in-point; press I (or click) to set start.
4. Move to the out-point; press O (or click) to set end.
5. Edit text/labels inline in the list view.
6. Use Snap-to-frame or Snap-to-marker for fine alignment.
7. Play a looped segment to verify timing.
8. Batch-shift or scale if the whole track needs adjustment.
9. Export to the desired format (SRT/VTT/CSV/EDL/JSON).

Tips & shortcuts

• I / O keys: Set in/out quickly.
• Shift + drag: Constrain movement to single axis (useful for nudging times).
• Ctrl/Cmd + Arrow: Nudge selected timing by one frame.
• Zoom timeline: Use scroll wheel or +/- keys to zoom in for frame edits.
• Preview without re-encoding: The tool syncs markers to the source file for fast checking.

Common issues & fixes

• Wrong frame-rate: Re-open project, set correct frame rate, then reapply timing adjustments.
• Off-by-one-frame errors: Enable or disable drop-frame mode and re-nudge by one frame.
• Export formatting differences: Choose SRT for wide compatibility; use CSV/JSON for automation.

Export checklist

• Confirm frame rate and timecode format.
• Verify no overlapping cues unless intended.
• Run a quick playback verification of exported file with your media player.
