You want to join those chaptered mp4 files together to make one continuous video?
Well that should be easy right? Well its a pain in the but and honestly I think the fact it takes like an hour to do it in GoPro Studio along with loading the video, converting it, stitching or joining it together and then re-encoding it is a bit rediculous when all you want to do is join the files.
So if you want to save a TON of time, and don't mind rolling up your sleeves and getting your hands just a little dirty with some command line usage, then try this:
Get yourself a copy of ffmpeg (https://www.ffmpeg.org/download.html).
Open the zip file and find the bin folder and copy out the ffmpeg.exe file to your desktop or somewhere on your computer.
Open a command prompt in windows and navigate to the folder where ffmpeg.exe now lives (wherever you put it).
Create a text file called "input.txt" in the same location that you placed ffmpeg.exe and add the list of videos you want concatenated into a single video to the text file in this format:
file GOPR1911.mp4
file GP011911.mp4
Obviously replace the filenames with your files and add more if you need to.
Then run ffmpeg using this command:
ffmpeg -f concat -i input.txt -c copy output.mp4
About 20 seconds later you'll have a SINGLE mp4 file for your gopro video, and you have gotten easily probably an hour or more back to your life.
Enjoy!
