How to batch change duration of clips, optionally apply video and audio fade at end

[bwnvideo]

Description of problem or question:

I have 500 video clips that are various lengths in various resolutions and sizes. I'd like to change them all to a length of 90 seconds from the beginning and then export them back out to a different folder with that new length and with a video and audio fade applied to each, without distorting the resolution or size of the clips.

How would I go about changing the duration of all video clips in a given folder at once, as a batch?

Is it possible also to apply a video and audio fade to the end of all of those same video clips?


Steps to reproduce the problem (If Applicable):

It isn't a problem.

Handbrake isn't the tool for what you want to do. Well, parts of it - the command line interface will allow you to limit the output length more simply than trying to use "batch add" in the GUI.

But the fade in/out isn't available in handbrake.
