Use a browser when selection is the job

A local browser tool works well when you want to see candidates, compare pictures, and save a manageable selection. There is no software installation, and the video stays on the device during extraction.

ClipStills focuses on this visual workflow: a few cover options, evenly spaced references, the start and end of a clip, or a contact sheet. You can inspect the results before committing to a large export.

Use FFmpeg when repeatability is the job

Desktop FFmpeg is useful for scripted processing, large batches, unsupported browser codecs, and complete image sequences. It gives you explicit control over filters and encoding, and it can be run repeatedly with the same settings.

It also requires care. Output folders can fill quickly; color and scaling options matter; and a command can overwrite files when configured to do so. Start with a short clip in a separate output folder.

Start with a time sample

This command uses FFmpeg’s fps filter to create approximately one PNG per second. It is useful for references, but it does not preserve every source frame. PNG files may be much larger than JPG files.

ffmpeg -i input.mp4 -vf fps=1 frame_%04d.png

For a full sequence, plan the output first

A complete sequence may create thousands of images in minutes of footage. Decide where the files should go, how much storage is available, and whether an image sequence is actually necessary. Confirm source timing if frame identity matters.

For professional color or timing work, keep the original source and validate a short export against your editor before running the entire job. ClipStills does not bundle FFmpeg or silently send unsupported files to a server.

Switch workflows without losing context

Start by exploring the video in the browser. Note the interval and timestamps you need, then move the demanding portion to your desktop tool if necessary. The optional export manifest keeps a simple record of your selected pictures and settings.

The best workflow is the one that reliably produces the required result at a manageable size. A small visual selection and a full-frame archive are different tasks.
