Please note that I am asking for 10bit, not 8bit. Thanks for replies
I installed the trial version for Movie studio platinum TWICE and the studio suite once and for all three times, the software did not support h.264 10bit 422 L-GOP so I guess the answer is a resounding "NO". If it works, please tell me. maybe I am doing something wrong?
Which version of Movie Studio Platinum? If it is v.18, it's not a VEGAS product any more and will be discussed only on the MAGIX user forum here https://www.magix.info/us/video-forum/movie-edit-pro/
