high 20mb - 27mins

Hi Chris, I can't reproduce this.

When I render the same clip in Lumion 1 Free in 1/2/3 Star quality I get the following result:

1 and 2 Star quality = Almost same file size
3-star quality = Smaller than 1 and 2 Star files

Could I ask you to test this again please?

Here are my results (I right-clicked on each MP4 file to get these details):

Test_2secs_1280_1star.mp4
