How to use Timestamped Video Storyboard
- Choose a supported video and set the first sample and excluded end time.
- Set the interval and number of thumbnails across the sheet.
- Build the storyboard and compare its timestamps with the source before exporting.
Example: Timestamped Video Storyboard
Make a short two-frame contact sheet.
Options
- Sampling interval
- Frames are requested from the first sample in interval-sized steps before the excluded end. At most 24 positions are allowed.
- Thumbnails across the sheet
- Two, three or four columns change contact-sheet layout. They do not change requested sample times.
Supported inputs and limits
Where your input is processed
This tool processes your input in this browser. Your text and files are not uploaded to UseFreeTools. Check this tool's limits for anything it may save on your device.
An interval is a sampling plan
Sampling once per second can miss a change between those times. Shorten the interval or choose another segment if that event matters, while staying inside the sample cap. The sheet is a sequence of still images; it does not preserve movement between them.
Timestamps are requested seek positions
The browser decoder supplies the frame near each seek position. This is not a frame-accurate editing timecode or a reconstruction of every encoded timestamp. Use the CSV to review the sampling plan and the source video to verify an important event.
Questions about Timestamped Video Storyboard
Does it detect scene changes automatically?
No. It uses your start, end and interval values.
Is the entered end time also sampled?
No. The end is excluded. A 0–2 second range at a one-second interval requests positions 0 and 1.
Is my input uploaded?
Nothing is uploaded.
