Join recorded files together

After recording files on Pearl-2, you can join two or more files together. This is useful when a recording exceeds the maximum recording time limit and the recording is split into multiple files. You can use the third-party tool called ffmpeg to join the files.

Download ffmpeg from the Internet and join multiple recorded files

  1. Download the files that you need from Pearl-2 and make sure you have the right paths and file names. For example:
  2. C:\Users\JoesComputer\downloads\Program_A_May11_16-24-56.avi

  3. Use the command ffmpeg -i to specify the input file. For example:
  4. ffmpeg -i C:\Users\JoesComputer\downloads\Program_A_May11_16-24-56.avi

  5. Repeat the process and specify the file you want to join to the first file. You can keep adding as many files as you want to join together. For example, specifying a second file looks like this:
  6. ffmpeg -i C:\Users\JoesComputer\downloads\Program_A_May11_16-24-56.avi -i C:\Users\JoesComputer\downloads\Program_A_May11_12-26-14.avi

  7. Use the -c copy command to specify the output file. After the command, type in the location, file name and file extension that you want for the concatenated file. The full line looks like this:
  8. ffmpeg -i C:\Users\JoesComputer\downloads\Program_A_May11_16-24-56.avi -i C:\Users\JoesComputer\downloads\Program_A_May11_12-26-14.avi -c copy C:\Users\JoesComputer\Desktop\Concatenated_File.avi

  9. After completing the process, you will be able to access your new file in the location you specified. The file moves straight from the first video into the second without a pause.

You can this process to join multiple files; however, the more files you join, the greater the chance that some audio desychronization can occur between the clips.
