Join / Concatenate Video Files

 138 | 139 | USING concat VIDEO FILTER (Performs re-encoding. Problem when dealing with videos of different resolution) 140 | 141 | `$ ffmpeg -i opening.mp4 -i content.mp4 -i ending.mp4 -filter_complex "[0:v] [0:a] [1:v] [1:a] [2:v] [2:a] concat=n=3:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" output.mp4` 142 | 143 | Use if your inputs do not have the same parameters (width, height, etc), or are not the same formats/codecs, or if you want to perform any filtering. (You could re-encode just the inputs that don't match so they share the same codec and other parameters, then use the concat demuxer to avoid re-encoding the other inputs). 144 | 145 | USING concat DEMUXER () 146 | 147 | $ cat mylist.txt 148 | file '/path/to/file1' 149 | file '/path/to/file2' 150 | file '/path/to/file3' 151 | 152 | $ ffmpeg -f concat -i mylist.txt -c copy output 153 | 154 | Use when you want to avoid a re-encode and your format does not support file level concatenation (most files used by general users do not support file level concatenation). 155 | 156 | USING concat PROTOCOL 157 | 158 | $ ffmpeg -i "concat:input1|input2" -codec copy output 159 | 160 | This method does not work for many formats, including MP4, due to the nature of these formats and the simplistic concatenation performed by this method. 161 | 162 | Use with formats that support file level concatenation (MPEG-1, MPEG-2 PS, DV). Do not use with MP4. 163 | 164 | Reference: [How to concatenate two MP4 files using FFmpeg?](https://stackoverflow.com/questions/7333232/how-to-concatenate-two-mp4-files-using-ffmpeg) 165 | 166 |

Extract Images from a Video

 321 | 322 | `$ ffmpeg -i input.mpg image%d.jpg` 323 | 324 | This will create 25 images for every 1 second, but it may serve us to have more or less images, this can be achieved with the parameter -r 325 | 326 | -r fps *Set frame rate (default 25)* 327 | 328 | `$ ffmpeg -i test.mpg -r 1 image%d.jpg` 329 | 330 | With this command you’ll get 1 image for every second. 331 | 332 | You can also give a start time and the duration with the flags: 333 | 334 | -ss position Seek to given time position in seconds. “hh:mm:ss[.xxx]” syntax is also supported. 335 | 336 | -t duration Restrict the transcoded/captured video sequence to the duration specified in seconds. “hh:mm:ss[.xxx]” syntax is also supported. 337 | 338 | This command will take 25 images images every second beginning at the tenth second, and continuing for 5 seconds 339 | 340 | `$ ffmpeg -i test.mpg -r 25 -ss 00:00:10 -t 00:00:05 images%05d.png` 341 | 342 |

Normalize (boost) audio

 364 | 365 | VIDEO: `ffmpeg -i original.mov -af "volume=18dB" -c:v copy -c:a aac -b:a 192k normalized.mov` 366 | 367 | **Important:** watch out for the typos, e.g. `18db` will fail, since the correct syntax is `18dB` (uppercase B). 368 | 369 | We also have created a handy shell (zsh) script that will normalize a file like this: 370 | 371 | ```bash 372 | normalize file.mov 373 | # Will create a file file.normalized.mov, normalized at 16dB (default) 374 | normalize --db 12 movie.mp4 375 | # Will create a file movie.normalized.mp4, normalized at 12dB 376 | ``` 377 | 378 | You can find the file here: [./scripts/normalize.sh](./scripts/normalize.sh) 379 | 380 | [References](https://superuser.com/questions/323119/how-can-i-normalize-audio-using-ffmpeg) 381 | 382 |
