One-second sampling
Requests a decoded image at each one-second timeline position.
Interval extraction
Extract a frame every second from a video
Create a regular image sequence with a one-second interval, or change the step to tenths of a second, several seconds, or minutes for the timeline coverage you need.

Every-second frames
Regular sampling for repeatable timeline coverage
Interval extraction is useful when cadence matters more than a fixed image count. A one-second step creates predictable timestamps such as 00:01, 00:02, and 00:03 across the selected range.
Before starting, compare the estimated output count with the 240-frame per-run limit. For long videos, increase the interval or divide the work into smaller ranges to protect browser memory.
Step-by-step
How to extract one frame per second
Use Interval mode and set Every to 1 second.
- 01
Load the video
Open a browser-playable local source.
- 02
Choose Interval mode
Enter 1 for one capture per second.
- 03
Limit the range
Set start and end values when only part of the timeline matters.
- 04
Extract and download
Export the images individually, as a contact sheet, or in a ZIP.
Compatibility
Interval extraction considerations
A time interval is not the same as extracting every encoded frame.
Shorter intervals
Create more images and can quickly reach the per-run limit.
Long videos
Use a larger step or multiple ranges for manageable batches.
Final frame option
Include the end of the selected range even when it falls between steps.
Best results
Plan interval batches
Check the planned output
Reduce the selection before extraction if it exceeds 240 frames.
Use 5 or 10 seconds for overviews
A larger interval often works better for long-form content.
Use PNG only when needed
Large PNG sequences consume more memory and disk space.
Keep timestamped names
They preserve the cadence and order of the sequence.
Support and limits
Interval mode boundaries
The browser seeks by timeline time; this is not an encoded-frame demuxer.
Supported workflow
- Intervals from 0.1 to 600 seconds
- Custom start and end range
- Optional last-frame inclusion
Current limits
- Maximum 240 images per run
- No guarantee of every encoded source frame
- Seek accuracy depends on codec and browser
FAQ
Questions about every-second frames
How do I extract one image every second?
Choose Interval mode and enter 1 in the Every field.
Can I use half-second intervals?
Yes. Enter 0.5 or another value of at least 0.1 seconds.
Why is my selection too large?
The tool limits a run to 240 frames for browser stability.
Can I include the last video frame?
Enable Include last frame.
Can I download the sequence as ZIP?
Yes. All extracted images can be packaged together.
