What is the fastest FFmpeg command for one frame?

Put -ss before -i, then use -frames:v 1. Seeking before input is much faster on long files than decoding from the start. Example: ffmpeg -ss 00:01:23 -i input.mp4 -frames:v 1 frame.jpg

How do I extract 1 frame per second with FFmpeg?

Use the fps filter: ffmpeg -i input.mp4 -vf fps=1 frames/out_%04d.jpg. For one frame every 5 seconds use fps=1/5. Create the output folder first.

Should I use JPG or PNG with FFmpeg?

JPG with -q:v 2 is a strong default for previews and datasets that tolerate light compression. PNG is better for lossless labeling and repeated re-encodes. Pick based on storage vs fidelity.

How to Extract Frames from Video with FFmpeg (Complete Guide)

FFmpeg can pull a single still, sample every N seconds, dump all frames, or keep keyframes only. Below are tested commands you can paste into a terminal — then a note on when a browser tool is faster.

Extract a single frame at a timestamp

Place -ss before -i so FFmpeg seeks first, then write exactly one video frame. This is the fastest pattern on long files.

ffmpeg -ss 00:01:23.000 -i input.mp4 -frames:v 1 frame.jpg

Swap the timestamp as needed. For PNG, change the output name to frame.png.

Extract one frame every N seconds

Use the fps filter. fps=1 means one frame per second; fps=1/5 means one frame every five seconds.

mkdir -p frames
ffmpeg -i input.mp4 -vf fps=1 frames/out_%04d.jpg

# one frame every 5 seconds
ffmpeg -i input.mp4 -vf fps=1/5 frames/out_%04d.jpg

Extract all frames

Omitting an fps filter writes every decoded frame. A 10-minute 30 fps clip can produce ~18,000 images — plan disk space first.

mkdir -p all_frames
ffmpeg -i input.mp4 all_frames/frame_%06d.png

Extract keyframes only

Keep I-frames with a select filter and variable frame rate output so duplicates are not invented between keyframes.

mkdir -p keyframes
ffmpeg -i input.mp4 -vf "select='eq(pict_type\,I)'" -vsync vfr keyframes/k_%04d.jpg

Control JPG quality with -q:v

For MJPEG/JPG outputs, -q:v 2 is a high-quality default (scale roughly 2–5 for visually excellent stills; higher numbers are smaller/lower quality).

ffmpeg -ss 00:00:10 -i input.mp4 -frames:v 1 -q:v 2 still.jpg

Prefer PNG when labels or repeated edits cannot afford generation loss. Prefer JPG when you need thousands of preview frames.

When a browser tool is faster

FFmpeg wins for scripts, servers, and hundred-file batches. A browser extractor wins when you need to see the timeline, try three thumbnail candidates, and download a ZIP without installing anything. For that path, open the free GetVideoFrames extractor — local, with no video upload. Browser and device limits apply. ML teams can also start on the dataset sampling tool.
