# List of things you can do:
# Usage: ffmpeg -i input.file <args> output.file
# where <args> equals the code pieces from this list


// Convert Music to lower bitrate
-map 0:a:0 -b:a 96k

//Aspect ratio
ffmpeg -i input.mp4 -aspect 16:9 output.mp4

//Double Speed (0.5 = x2)
ffmpeg -i input.mp4 -vf "setpts=0.5*PTS" output.mp4

//Double audio speed
ffmpeg -i input.mp4 -filter:a "atempo=2.0" -vn output.mp4

//Set bitrate (compresses if lower than source, a = audio, v = video)
-b:v 1M
-b:a 96k

//Volume of audio
ffmpeg -i input.mp3 -af 'volume=1.5' output.mp3

//Change scale of video (iw = width, ih = height, -1 means auto)
-vf scale="iw/2:-1"
-vf scale="1280:720"

//Crop (Cut) Video, w=width, x=startpoint for the rectangle w/h
ffmpeg -i input.mp4 -filter:v "crop=w:h:x:y" output.mp4

//Quicker video scaling
-i input.mp4 -filter:v scale=1280:720 -c:a copy output.mp4

//Video to images (Names are image-001.png, image-002.png, ...)
//-r = framerate in which screenshots are taken, default=25
//%3d = name, 001 - 999
ffmpeg -i input.mp4 -r 1 -f image2 image-%3d.png

//Add Text to the video
-vf drawtext="text='MyTextHere': fontcolor=white: fontsize=24: x=(w-text_w)/2: y=(h-text_h)/2"

//Combine 2 videos
ffmpeg -i in_one.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts _1.ts
ffmpeg -i in_two.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts _2.ts
ffmpeg -i "concat:_1.ts|_2.ts" -c copy -bsf:a aac_adtstoasc together.mp4

//Compress video (Should be between 20 and 28, 51 is max and looks ew)
-crf 24
-crf 51


//Change Video Codec ('copy' means copy the input video codec)
-vcodec h264
-vcodec libvpx
-vcodec copy


//Change Audio Codec
-acodec aac
-acodec mp3
-acodec copy


//Remove Audio / Video
-an
-vn

//Remove video would be:
ffmpeg -i input_video.mp4 -vn output_audio.mp3

//Example mp4 to mp3 convert
ffmpeg -i in.mp4 -vn -acodec mp3 out.mp3

//Convert a video from 30 to 60 FPS
ffmpeg -i Input.mp4 -filter:v "minterpolate='fps=60'" Out60.mp4

//Make 2 input files side by side (-r makes the framerate be 60)
ffmpeg -i 30.mp4 -i 60.mp4 -r 60 -filter_complex hstack comparison.mp4

//Cut Video (time either in 00:01:23.000 or in seconds format, here seconds are used)
//This would cut the video, so that only second 3 to 8 plays (5 seconds long)
// -t = duration, -ss = starttime
-ss 3 -t 5

//Burn in subtitles
ffmpeg -i in.mkv -vf subtitles=in.mkv out.mp4

//Meme top and bottom text with white padding background
ffmpeg -i input.mp4 -filter_complex \
"[0:v]pad=iw:ih+100:0:(oh-ih)/2:color=white, \
 drawtext=text='ONE DOES NOT SIMPLY':fontsize=24:x=(w-tw)/2:y=(50-th)/2, \
 drawtext=text='STOP ME FROM FILTERING':fontsize=24:x=(w-tw)/2:y=h-25-(th/2)" \
output.mp4

//Convert a folder from mp4 to mp3
for i in *.mp4; do ffmpeg -i "$i" "$(basename "$i" .mp4)".mp3  ; done

// Copy codes (copy video and audio stream, makes video cutting way quicker)
-c copy
