Video Duration From Frames

Summary

Enter total frame count and fps to instantly get video duration as HH:MM:SS.mmm and total seconds.

How it works

1. Enter the total number of frames in your video.
2. Select or type in a frame rate (fps) — common rates like 23.976, 29.97, and 59.94 are preloaded.
3. The duration updates instantly as HH:MM:SS.mmm and total seconds.
4. Use the copy buttons to grab the result for use in an editor or script.

Use cases

• Verify the expected duration of a rendered video from its frame count.
• Convert render queue frame ranges to wall-clock time for scheduling.
• Calculate how long a specific sequence of frames will play at a given fps.
• Check sync between a frame-based timeline and a timecode-based system.
• Estimate export time by knowing the total frames before rendering.
• Validate frame counts match expected duration for quality control.
