- This text file contains the list of files to be concatenated and should be formatted as follows: + This text file contains the list of files (without their absolute path) to be concatenated and should be formatted as follows:

+  file 'first_file.ext'
+  file 'second_file.ext'
   . . .
-  file './last_file.ext'
+  file 'last_file.ext'
In the above, file is simply the word "file". Straight apostrophes ('like this') rather than curved quotation marks (‘like this’) must be used to enclose the file paths.
Note: If specifying absolute file paths in the .txt file, add -safe 0 before the input file.

Join files together

ffmpeg -f concat -i mylist.txt -c copy output_file

-

This command takes two or more files of the same file type and joins them together to make a single file. All that the program needs is a text file with a list specifying the files that should be joined. However, it only works properly if the files to be combined have the exact same codec and technical specifications. Be careful, FFmpeg may appear to have successfully joined two video files with different codecs, but may only bring over the audio from the second file or have other weird behaviors. Don’t use this command for joining files with different codecs and technical specs and always preview your resulting video file!
