# Output a single frame from the video into an image file:
ffmpeg -i input.mov -ss 00:00:14.435 -vframes 1 out.png

# Output one image every second, named out1.png, out2.png, out3.png, etc.
# The %01d dictates that the ordinal number of each output image will be formatted using 1 digits.
ffmpeg -i input.mov -vf fps=1 out%d.png

# Output one image every minute, named out001.jpg, out002.jpg, out003.jpg, etc. 
# The %02d dictates that the ordinal number of each output image will be formatted using 2 digits.
ffmpeg -i input.mov -vf fps=1/60 out%02d.jpg

Compile FFmpeg on Ubuntu

This basic guide supports Ubuntu Xenial Xerus 16.04 and will enable several external encoding and decoding libraries: libfaac (AAC encoder), libfdk-aac (AAC encoder), libmp3lame (MP3 encoder), libopencore-amr (AMR encoder/decoder), librtmp (for additional RTMP protocols), libtheora (Theora encoder), libvorbis (Vorbis encoder), libvpx (VP8 encoder/decoder), and libx264 (H.264 encoder). These are optional and may be omitted if desired. This guide will also install many filters (see the filter list in the [Filtering Guide][1].

Note: Copy and paste the whole code box for each step.
