This tells ffmpeg to start at 24m50s and extract 1m25s of output. Your 
file is just under 7 minutes long.

It should be,

     -ss 25 -to 1:25

Depending on where the nearest keyframe is, your output may not include 
a few seconds near the start point. Decrement the start time by a few 
seconds to accommodate that, or keep it the same and transcode (drop 
-c:v copy).
