Good App, but fixes needed!

When I try to share the video to Videos, somehow it was messed up and now I cant share it to YouTube. If Im doing something wrong, please tell me. If this is something wrong with the app, fix it!

I really love this app, and I use it so much, but now I cant upload Lego Videos for my YouTube channel! PLEASE FIX IT!!!
