This is the problem that I was facing: I wanted to combine an old video file (in .AVI format) that I have taken with my 2001 digital camera and a new video file (in .MP4 format) of 2022 into one and the same video file (in .MP4 format).
There are many good video editing programs out there, and one of them is Camtasia. I am using Camtasia a lot but if you don’t produce so many videos, maybe Screencast-o-Matic is the right thing for you: the free version of Screencast-o-Matic records screencast and webcam videos up to 15 minutes long. Paid plans allow longer videos, stock photos and more.
Here is what has happened: after importing the old .AVI file into Camtasia, this file cannot be added to the timeline and no other files can be imported into Camtasia. The Camtasia user forum mentions this problem (click here).
This is what the Camtasia user forum says:
This occurs when importing an AVI file that is not encoded in TSC2 or TSCC codecs. The best workaround is to convert the AVI to MP4 using Handbrake.
Download Handbrake and watch the tutorial below to learn how to convert the file to MP4 using Handbrake.
The tutorial is only 01:39 minutes long, and it works. Start with converting single files before you use the batch mode. The Handbrake program is quite intuitive.
