MKV file. how to convert.

[Mickey]

How would I Insert the bob.mkv in the line below ?

/usr/bin/ffmpeg -i $1 -acodec aac -ab 96k -vcodec libx264 -preset slow 
-f mp4 -crf 22 -strict experimental $1.mp4

I tried to use Miro but it just keeps CRASHING.

(cut & paste mishap)

/usr/bin/ffmpeg -i bob.mkv -acodec aac -ab 96k -vcodec libx264 -preset slow -f mp4 -crf 22 -strict experimental bob.mp4

Thanks Ed , I'm a little rusty at reading the man page, but I'm working 
on it.

Welcome.....

Hint....   *Generally* 9 times out of 10 the -i parameter indicates "input" and -o indicates output.  In the absence of -o the output is either going to STDOUT or a file named as the last argument on the line.

If you have a multicore CPU, after the "ffmpeg" command before the -i you can 
add something like "-threads 2" which will reduce the clock time to convert at 
the cost of bogging down your system a bit more. Larger numbers are allowed but 
the bog factor goes up faster than the real time gets smaller, so rarely worth 
using more than two.
