Universal media converter usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

  Getting help:

-h -- print basic options

-h long -- print more options

-h full -- print all options (including all format and codec specific options, very long)

-h type=name -- print all options for the named decoder/encoder/demuxer/muxer/filter/bsf/protocol

    See man ffmpeg for detailed description of the options.

Per-stream options can be followed by :<stream_spec> to apply that option to specific streams only. <stream_spec> can be a stream index, or v/a/s for video/audio/subtitle (see manual for full syntax).

Print help / information / capabilities: -L show license -h <topic> show help -version show version -muxers show available muxers -demuxers show available demuxers -devices show available devices -decoders show available decoders -encoders show available encoders -filters show available filters -pix_fmts show available pixel formats -layouts show standard channel layouts -sample_fmts show available audio sample formats

Global options (affect whole program instead of just one file): -v <loglevel> set logging level -y overwrite output files -n never overwrite output files -print_graphs print execution graph data to stderr -print_graphs_file <filename> write execution graph data to the specified file -print_graphs_format <format> set the output printing format (available formats are: default, compact, csv, flat, ini, json, xml, mermaid, mermaidhtml) -stats print progress report during encoding

Per-file options (input and output): -f <fmt> force container format (auto-detected otherwise) -t <duration> stop transcoding after specified duration -to <time_stop> stop transcoding after specified time is reached -ss <time_off> start transcoding at specified time

Per-file options (output-only): -metadata[:<spec>] <key=value> add metadata

Per-stream options: -c[:<stream_spec>] <codec> select encoder/decoder ('copy' to copy stream without reencoding) -filter[:<stream_spec>] <filter_graph> apply specified filters to audio/video

Video options: -r[:<stream_spec>] <rate> override input framerate/convert to given output framerate (Hz value, fraction or abbreviation) -aspect[:<stream_spec>] <aspect> set aspect ratio (4:3, 16:9 or 1.3333, 1.7777) -vn disable video -vcodec <codec> alias for -c:v (select encoder/decoder for video streams) -vf <filter_graph> alias for -filter:v (apply filters to video streams) -b <bitrate> video bitrate (please use -b:v)

Audio options: -aq <quality> set audio quality (codec-specific) -ar[:<stream_spec>] <rate> set audio sampling rate (in Hz) -ac[:<stream_spec>] <channels> set number of audio channels -an disable audio -acodec <codec> alias for -c:a (select encoder/decoder for audio streams) -ab <bitrate> alias for -b:a (select bitrate for audio streams) -af <filter_graph> alias for -filter:a (apply filters to audio streams)

Subtitle options: -sn disable subtitle -scodec <codec> alias for -c:s (select encoder/decoder for subtitle streams)
