[FFmpeg-user] HELP !

[Nicolas Sampson]

Hello Peter and thank you for the immediate reply.  Yes, that spelling
error was picked up after I sent the email.  As I stated when I joined
about 1 hour ago, I am not a programmer, so I would ask you how to run the
formula you quoted......do I open a cmd window and type the formula in it
or should I save it a a <.bat> and then run it?  Do I copy the formula or
batch file into the <ffmpeg\bin> folder?  Sorry but I feel stupid asking
these questions !!!  Also is the formula set out in one line, and is there
a 'space' after <-y>

Thanks again and sorry for the trouble.

Regards,



*Nicolas "Sam" Sampson.*
