Hey guys, so after many many failed attempts, I believe I partially tamed the monster. I posted the new tutorial on the blog: http://www.stefanchirila.com/blog/2016/12/11/how-to-stitch-a-panorama-with-hugin-and-rawtherapee-screencast-tutorial/
RAW files and preset available. Enjoy, but do say thank you by sharing your opinion.
Here's what happened, I was planning on having music in the background of my narrating and when I finished the video I realised I was so nervous I forgot to turn the music player on ...doh! So I exported the sound of the video using Audacity as a FLAC and imported it into Ardour and mixed it in with the music I wanted. Then I exported as an ogg, removed the sound completely from the video and added the new sound to the video.
For those who care:
ffmpeg -i [input_file] -vcodec copy -an [output_file]
ffmpeg -i example.mkv -c copy -an example-nosound.mkv
ffmpeg -i video.avi -i audio.mp3 -codec copy -shortest output.avi
ffmpeg -i video.avi -i audio.mp3 -c:v libx264 -c:a libvorbis -shortest output.mkv
