= `-frames` option =

Output a single frame from the video into an image file:

{{{
ffmpeg -i input.flv -ss 00:00:14.435 -frames:v 1 out.png
}}}

This example will [[Seeking|seek]] to the position of 0h:0m:14sec:435msec and output one frame (`-frames:v 1`) from that position into a PNG file.

= `fps` video filter =

Output one image every second, named `out1.png`, `out2.png`, `out3.png`, etc.

{{{
ffmpeg -i input.flv -vf fps=1 out%d.png
}}}

Output one image every minute, named `img001.jpg`, `img002.jpg`, `img003.jpg`, etc. The `%03d` dictates that the ordinal number of each output image will be formatted using 3 digits.

{{{
ffmpeg -i myvideo.avi -vf fps=1/60 img%03d.jpg
}}}

Output one image every ten minutes:

{{{
ffmpeg -i test.flv -vf fps=1/600 thumb%04d.bmp
}}}

= `select` video filter =

Output one image for every I-frame:

{{{
ffmpeg -i input.flv -vf "select='eq(pict_type,PICT_TYPE_I)'" -vsync vfr thumb%04d.png
}}}

= `thumbnail` video filter =

Pick one of the most representative frames in sequences of 100 consecutive frames:

{{{
ffmpeg -i input.flv -vf thumbnail=n=100 thumb%04d.png
}}}
