> If I find time, how can your tests be reproduced? I used 3 free videos taken from: https://mixkit.co/free-stock-video/ I compressed them and you can find them in my dropbox: https://www.dropbox.com/s/9oclu8vb882xbz9/mixkit-.tar.gz?dl=0 I simply concatenated them on the timeline and did the rendering (they have no audio tracks).
