FFmpeg on windows cut and fade question
I would like to answer my own question.
One thing tho is the file is quite large (370+ lines) so i have added it to pastebin
FF Fader on Pastebin
A few Notes:
I had errors popping up if the cuts were certain lengths like on a 30 sec video and I wanted over 10 sec  cuts it would work but toss up errors such as
Invalid number.  Numeric constants are either decimal (17),
hexadecimal (0x11), or octal (021).
Invalid number.  Numeric constants are either decimal (17),
hexadecimal (0x11), or octal (021).

this error would be cause form the calculations at lines:
218 to 229
lines 218 - 229 were added by another issue i found was if you did a 6 sec segments, the last cut was shorter than 2 seconds  so if that was the case i would need to concat that way cause it was concating (sp?) that last clip twice
If that is not correct way of answering the question here, please help me fix it b4 down voting me etc.  I am new here
I would love some input and if you see where it can be cleaned up that would be great too
EDIT:
Wanted to add that taking a 30 second video and cutting into 3 segments, then cutting those 3 segments into 3 sections.  add the fade in and fade out and then combine them all back into segments  took right at 30 seconds or less!
That is pretty awesome! I think maybe using &quot;threads&quot; on ffmpeg could speed it up  but I am not sure you need it any faster than that.  If you have a idea to speed up ffmpeg more let me know in the comments.
