It could be nice to have a GUI for the console application, maybe in a new project?

User should be able to specify a text as watermark to place in one of the corners of the generated trailer.

Option could be something like --watermarktext "some text" --watermark-position "bottom-left" --watermark-size "a font size eg. 12 or 14"

Input format may be a zip, the idea would be to cut various parts of the files and blend them together

This is due to the way streams from video file are retrieved

If there's more than one stream, the retrieval will fail

Some cut videos could be randomly slowed down

Command

trailer-maker -f "/home/alex/a file name.avi" -d 5000 -l 2000
will fail with error
Exception in thread "main" java.lang.IllegalArgumentException: step cannot be 0
This is because the comandline used doesn't handle so well spaces

In function parseArgs there's a lot of repetition in the code.

There might be a way to enhance this implementing fold.

It could be great to have the possibility to:

• replace the original video sound with music
• OR keep the video sound and add a music playback over it
