Thanks.

I have another issue, and a question

1. The second file doesn't play in VLC, so it looks like I got the
switches wrong again:

ffmpeg.exe -i input.mp4 -ss 00:00:00 -t 01:00:00 -c:v copy -c:a copy
FL.1.mp4

'rewind 10s for smoother listening
'input.mp4 is actually 1h38mn in length
ffmpeg.exe -i input.mp4 -ss 00:59:50 -t 01:00:00 -c:v copy -c:a copy
FL.2.mp4

2. 1. Does it make a difference if I put the "-ss -t" before or after
the "-i" switch?

ffmpeg.exe -ss 00:00:00 -t 01:00:00 -i input.mp4 -c:v copy -c:a copy
FL.1.mp4

Thank you.
