48
00:06:13,530 --> 00:06:14,460
lt's about time you got married,

49
00:06:14,530 --> 00:06:18,530
Before you turn into
a lonesome and bitter, old man.

50
00:06:19,730 --> 00:06:21,860
yeah, can't you just see me?

51
00:06:23,000 --> 00:06:25,000
Rushing home to a hot apartment

52
00:06:25,060 --> 00:06:29,060
To listen to the automatic laundry
and the electric dishwasher

53
00:06:29,130 --> 00:06:33,130
And the garbage disposal
and the nagging wife.

-=== Redirecting stderr to stdout ===
-ffmpeg's output is actually to the ''stderr'' and not the ''stdout''. In other words, its output is tagged as "error" information, and the ability to distinguish between this and "regular" information can sometimes be useful. In this case however, we want ffmpeg's output to be treated like "regular" command output. You do this by "redirecting stderr to stdout" with the rather cryptic addition of "2>&1".
