I have two cell phone videos the first 45 seconds and the second 30 seconds. I would like to merge them together and upload to youtube.com. I also need to insert introductory video leaders:
- a 3 second introductory clip "This is before repair"
- first video of 45 seconds
- a 3 second introductory clip "This is after repair"
- second video
What tools are available to create this youtube.com video in Ubuntu 16.04 (I also have Ubuntu 19.04 installed)?
Note: I didn't specify a video file format when I made the two videos on my cell phone but it is running Android 7 I believe.
