Pick the moments worth capturing as thumbnails

Editors and channel managers use it before artwork is made to identify the moments most likely to stop a viewer scrolling.

Pick the moments worth capturing as thumbnails. The output stays on your device and is ready to copy or adapt as soon as it appears.

How to use

Put the full length of your video in minutes on the first line of the input.
Enter how many thumbnail candidates you want on the next line, based on how much choice you need.
Run compose to get a set of moments worth reviewing as possible captures.
Look through the list and mark the shots that best represent the video or product.
If your edit notes are already digital, import a text or CSV file instead of typing everything again.

Example

For an eighteen-minute review, ask for five thumbnail moments. The tool spreads candidate points across the running time. You can then jump to those places in your editor, pause, and capture frames that show the product clearly. Compare the frames before choosing one.

Limits and formats

It never views the footage or scores how appealing a frame looks to a viewer.
The suggested points are estimates and need checking in the actual edit.
A high number of thumbnails can create suggestions that sit very close together.
Final captures must still follow the image rules of the platform you use.
If the video covers several subjects, add clearer source notes to narrow the search.

Where processing happens

The work is done inside your browser. The length and thumbnail count you provide stay on your device, and the suggested list appears locally without being sent away. This makes it suitable for unpublished projects.

Frequently asked questions

Does this work for vertical videos?

Yes. The tool only uses duration and a requested number, so orientation does not change the process. You should still confirm that the suggested moments look balanced in a vertical frame, especially when the subject moves across the screen.

How many thumbnails should I ask for?

Choose based on how much choice you need. A small number gives a quick shortlist, while a larger number offers more options but also creates more frames to capture and compare in your editor. Start with a modest request and increase it if needed.

Are the proposed moments exact?

They are calculated from the total length and the number you enter, so treat them as pointers. Open the edit around each point, because the strongest frame may appear a little earlier or later. Manual adjustment is normal.
