Constant frame rate
Usually produces predictable neighboring frames for a known time.
Exact timestamp capture
Extract a video frame at the timestamp you specify
Paste one or several timecodes and capture the corresponding decoded frames. This workflow is designed for edit notes, bug reports, evidence, and repeatable review tasks.

Timestamp frame
Repeatable captures instead of manual screenshots
A timestamp list makes a frame request reproducible. Teammates can keep the timecode with the exported filename and return to the same area of the video later.
Browser seeking is time based rather than frame-number based. The tool requests the specified time, then captures the frame that the browser decoder presents at that point.
Step-by-step
How to capture frames by timestamp
Times can be separated by commas, spaces, semicolons, or new lines.
- 01
Load and preview the video
Confirm that the browser can decode and seek the local source.
- 02
Choose Times mode
Open the timestamp field instead of interval or count mode.
- 03
Enter exact times
Use values such as 12.5, 00:12.500, or 01:03:12.250.
- 04
Extract and label
Export images whose filenames include their requested time.
Compatibility
Timestamp accuracy explained
Container indexes, keyframes, and variable frame rate can affect the exact decoded result.
Variable frame rate
A timeline time may not correspond to a simple fixed frame number.
Long-GOP codecs
The decoder may seek from a nearby keyframe before presenting the target area.
Edit timeline differences
Professional editors may use source timecode metadata the browser does not expose.
Best results
Precise capture practices
Include milliseconds
Use decimal seconds when whole-second capture is too coarse.
Try neighboring values
For fast action, add times a few hundredths of a second apart.
Use PNG for evidence
Lossless output protects small text and fine edges.
Record the source version
Timestamp repeatability depends on using the same video file.
Support and limits
Time-based, not frame-number extraction
The web video API exposes playback time, so the tool cannot promise an editor-specific source frame number.
Supported workflow
- Seconds, mm:ss, and hh:mm:ss.ms inputs
- Multiple timestamps in one run
- Timestamped JPG, PNG, and WebP filenames
Current limits
- No embedded camera timecode reading
- No SMPTE drop-frame calculation
- Nearest decoded frame may differ around codec boundaries
FAQ
Questions about timestamp frame
What timestamp formats work?
Use seconds, mm:ss, or hh:mm:ss.ms, including decimal fractions.
Can I paste multiple timestamps?
Yes. Separate them with commas, spaces, semicolons, or lines.
Is the frame exact to the millisecond?
The requested time is precise, but the decoder returns the frame available at that point.
Can I capture the player position instead?
Yes. Use Capture current after scrubbing.
Will filenames show the time?
Yes. Each exported filename includes a safe timestamp.
