How to use FFmpeg

Open "Command Prompt" or "PowerShell"

If you haven't set the path to FFmpeg, type the path in beginning of the command.

Or

If you have set the path to FFmpeg, simply type "ffmpeg" in beginning of the command.
eg : ffmpeg .....

Basics of FFmpeg

ffmpeg -i (INPUT_FILE) (OPTIONS) (OUTPUT_FILE)

-i              : Introducing the input file. (INPUT_FILE)    : Path of the input file. (OPTIONS)      : Set options according to your necessary. (OUTPUT_FILE)  : Set the path to output file. (Set the extension with a dot | eg: output.mp4 / output.mkv / output.webm....)

REMUX Videos

ffmpeg -i (INPUT_FILE) -c copy (OUTPUT_FILE)

This will copy first video track, first audio track and first subtitle track from input to output format.
eg : ffmpeg -i input_video.mkv -c copy output_video.mp4


ffmpeg -i (INPUT_FILE) -c:v copy -c:a copy -c:s copy (OUTPUT_FILE)

You can copy video/audio/subtitle track one by one from above code

ffmpeg -i (INPUT_FILE) -c:v copy -c:a copy -sn (OUTPUT_FILE)

This will remux the video without subtitle track
-sn --> Don't copy subtitle track

ffmpeg -i (INPUT_FILE) -c:v copy -an -sn (OUTPUT_FILE)

This will remux the video without audio and subtitle tracks
-an --> Don't copy audio track

ffmpeg -i (INPUT_FILE) -vn -c:a copy -sn (OUTPUT_FILE)

-vn --> Don't copy video track
eg : ffmpeg -i input_video.mp4 -vn -c:a copy -sn output_audio.m4a

Track Selecting

ffmpeg -i input.mkv -map 0 -c copy output.mkv

-map 0 --> Select all the streams available in the input file (0 means the first input)

eg : Assume you are using 3 input files and you want to add
the first stream from first input and the all audios from second input and all subtitles from third input to the output file,
below is the command,

ffmpeg -i 1.mkv -i 2.mkv -i 3.mkv -map 0:0 -map 1:a -map 2:s -c copy output.mkv

When using -map the first stream is 0, second stream is 1, third stream is 2 ......etc.

"-map" Usage

-map 0    --> Select first input -map 0:0  --> Select first input's first stream (track) -map 0:v  --> Select first input's all video streams (tracks) -map 0:a  --> Select first input's all audio streams (tracks) -map 0:s  --> Select first input's all subtitle streams (tracks) -map 0:v:0 --> Select first input's first video stream (track) -map 0:a:0 --> Select first input's first audio stream (track) -map 0:s:0 --> Select first input's first subtitle stream (track)

Track Extracting

Assume you have a MKV file with following tracks

1 - H.264 | Video track 2 - AAC   | First audio track 3 - EAC3  | Second audio track 4 - SRT   | First subtitle track 5 - SRT   | Second subtitle track 6 - SRT   | Third subtitle track

Extract the video track (Any of below codes)

ffmpeg -i input_video.mkv -map 0:0 -c copy output.h264
ffmpeg -i input_video.mkv -map 0:0 -c copy output.264
ffmpeg -i input_video.mkv -map 0:0 -c copy output.avc
ffmpeg -i input_video.mkv -map 0:v:0 -c copy output.h264
ffmpeg -i input_video.mkv -map 0:v:0 -c copy output.264
ffmpeg -i input_video.mkv -map 0:v:0 -c copy output.avc

NOTE : Codec extensions

H.264 --> .h264 / .264 / .avc H.265 --> .h265 / .265 / .hevc VP9   --> .ivf AV1   --> .ivf

Extract the audio track | AAC (Any of below codes)

ffmpeg -i input_video.mkv -map 0:1 -c copy output.aac
ffmpeg -i input_video.mkv -map 0:1 -c copy output.m4a
ffmpeg -i input_video.mkv -map 0:a:0 -c copy output.aac
ffmpeg -i input_video.mkv -map 0:a:0 -c copy output.m4a

Extract the audio track | EAC3 (Any of below codes)

ffmpeg -i input_video.mkv -map 0:2 -c copy output.eac3
ffmpeg -i input_video.mkv -map 0:2 -c copy output.mka
ffmpeg -i input_video.mkv -map 0:a:1 -c copy output.eac3
ffmpeg -i input_video.mkv -map 0:a:1 -c copy output.mka

NOTE : Codec extensions

AAC    --> .aac / .m4a / .mka AC-3   --> .ac3 / .mka EAC3   --> .eac3 / .mka Opus   --> .opus / .ogg / .mka /.webm FLAC   --> .flac / .ogg / .mka WAV    --> .wav / .mka DTS    --> .dts / .mka TrueHD --> .thd / .mka

Extract the subtitle track as .srt (Any of below codes)

ffmpeg -i input_video.mkv -map 0:3 -c:s srt output.srt | First subtitle track
ffmpeg -i input_video.mkv -map 0:4 -c:s srt output.srt | Second subtitle track
ffmpeg -i input_video.mkv -map 0:5 -c:s srt output.srt | Third subtitle track
ffmpeg -i input_video.mkv -map 0:s:0 -c:s srt output.srt | First subtitle track
ffmpeg -i input_video.mkv -map 0:s:1 -c:s srt output.srt | Second subtitle track
ffmpeg -i input_video.mkv -map 0:s:2 -c:s srt output.srt | Third subtitle track

Track Encoding

ffmpeg -i (INPUT_FILE) -c:v (VIDEO_CODEC) -c:a (AUDIO_CODEC) -c:s (SUBTITLE_CODEC) (OUTPUT_FILE)

* If you don't want to re-encode the audio track use -c:a copy

VIDEO_CODEC

H.264 --> libx264 H.265 --> libx265 VP9   --> libvpx-vp9 AV1   --> libaom-av1

AUDIO_CODEC

AAC          --> aac AC-3         --> ac3 EAC3         --> eac3 Opus         --> libopus FLAC         --> flac WAV (16bit)  --> pcm_s16le WAV (24bit)  --> pcm_s24le

SUBTITLE_CODEC

SRT  --> srt

*NOTE : For adding subtitles to a MP4/MOV file use -c:s mov_text code.

Crop

Use -filter:v "crop=1920:816" or -vf "crop=1920:816"

eg: Assume you have a footage with 1920x1080 resolution and you want to crop it to 1920x800, you can use below code,
ffmpeg -i (INPUT_FILE) -c:v (VIDEO_CODEC) -vf "crop=1920:800" -c:a copy (OUTPUT_FILE)

Resize/Rescale

Use -filter:v scale=1920x1080 or -vf scale=1920x1080

Or

Use -filter:v scale=1920:-1 or -vf scale=1920:-1

This automatically adjust the height according to the width according to the original aspect ratio
for 1440p (2K) downscaling -vf scale=2560:-1
for 1080p downscaling -vf scale=1920:-1
for 720p downscaling -vf scale=1280:-1


Trim

Trim by timestamps

ffmpeg -i (INPUT_FILE) -ss 00:00:00 -to 00:00:00 -map 0 -c copy (OUTPUT_FILE)

-ss 00:00:00 --> Set trim start time.
-to 00:00:00 --> Set trim end time.
(Format is HH:MM:SS)

Trim by frames

ffmpeg -i (INPUT_FILE) -ss I/FPS -to I/FPS -map 0 -c copy (OUTPUT_FILE)

-ss I/FPS --> Set trim start time.
-to I/FPS --> Set trim end time.

I - Frame number
FPS - Input file's frame rate

eg : Assume you have a 25fps footage and you want to trim it from 250 frame to 3500 frame, below is the code,

ffmpeg -i (INPUT_FILE) -ss 10 -to 140 -map 0 -c copy (OUTPUT_FILE)

-ss 10 = -ss 250/25
-to 140 = -ss 3500/25
