A post download script which reads a video file and then adjusts the frameEnd accordingly

[JamesBotterill]

A small postdownload module that will review metadata a video file and adjust the frameEnd point of the job.template accordingly.

Proposed inputs:

{
file : 'video.mp4', // the name of the file that needs to be analysed
framerate : 30 //This is the framerate of the composition,
padding : 120 //this is padding based on other elements in the project like a intro Default is 0
}

Was thinking of passing it through ffmpeg to get the data.

The one thing I think i'd need is to get the job.workpath exposed, or is this available to modules and is undocumented?
