I could perhaps use another tool, but I'd like to understand where I'm going wrong with ffmpeg because I do believe it is capable of doing what I want if I learn how it works. > > I could salvage the file by uploading to eg GDocs / YouTube and > re-downloading.

I have had experience of a phone creating a 'truncated' file which cut off before the actual due to a corrupt MOOV atom / extraneous 'ftyp' atoms. The video file played correctly on the phone and on online viewers (eg YT) but not with either VLC, ffplay, etc. I could salvage the file by uploading to eg GDocs / YouTube and re-downloading.

It is germane to know what version a querent is using and with which options.
