Just finished watching. Great Idea.
About lengh: I don't think you should aim for a certain amount of time, more like one full "chapter" with varying lenghts. Examples:
- Invasion of Poland
- Transition from Conquest of Poland to Begin of Attack on France
- Invasion of France
- Transitional Period
- Invasion of Balkans or Scandinavia or....
Could not get a working connection to the big files though , small ones look quite good, too though.
