Do you think you could explain further if you have a second? I tried taking my timeline. Changing the sequence settings to proress422(hq) after that i had to rerender it went through the entire render process only to pop an error message up saying codec not found or something along those lines. This is really becoming a problem have you run into this before? And what you suggested worked?
And in response to the other vlc player shows a gray screen at the points i see it skip/freeze in QT
