With OpenShot it is very easy to append multiple recordings into one new video. However, using OpenShot forces you to render the video again.

  • Make sure you open the a new project in Full HD mode (Edit | Preferences | Profile | HD 1080 25pfs)
  • Drag your clips into the left window with project files
  • From the project files, drag the clips to a track and position them in the correct order

When you are ready you can export the video by pressing the red button.

  • Change the output folder to match your recording folder and save the video as "video.mp4"
  • Select a video quality

Medium results in 5Mbps while High produces a 15Mbps video.

  • Click Export VIdeo to continue

Now you have prepared your recording folder with the new trimmed clip and you are ready to publish.
