Therefore the option -f image2 must precede the image sequence given as input. The parameters witch apply to the input files must precede them. output_file path, name and extension of the output file Discussion pix_fmt yuv420p The pixel format for “YUV” colour space with 4:2:0 chroma subsampling and planar colour alignment is chosen for best compatibility. crf constant_rate_factor A parameter of 18 means a “visually lossless” compression. preset preset_value A slower encoding preset means a better compression rate. pix_fmt yuv420p \ output_file Command syntax ffmpeg starts the command -f image2 forces the image file de-muxer for single image files -framerate frames_per_second sets the frame rate -i input_file_regex.ext path, name with regex and extension of the input files -c:v libx264 The library libx264 re-encodes the video stream using the H.264 video codec.
pix_fmt yuv420p \ output_file General command ffmpeg \ Transcode an image sequence by using the H.264 codec for dissemination purposes.
