## Scripts

Each script command is named, and will be executed in order of appearance. Errors
will be reported and execution will stop if the exit code is non-zero, using
the names as logical pointers.

### Command lines

Command line uses placeholders.

        {%input}    The input filename, escaped for the command line
        {%uinput}   Unescaped input filename
        {%output}   The output filename, escaped for command line
        {%uoutput}  Unescaped outptu filename

Any parameters will also be available:

        {%paramname} 

And you can use `set` to assign stuff to variables.

### Parsing output

To parse the output, add a `parse` key to the command block.

        parse:
            regex:    <- expression
            frame:    <- index of frame number, or leave out
            fps:      <- index of frames per second, or leave out
