There might be more than one problem with your settings. Is this log from before or after you changed to progressive video?
Is that what you meant with disabling interlacing? Because I tried that yesterday and it actually worked! The whole time the problem was right infront of me I just didn't notice it because I never change the field order since the default is "none (progressive scan)" but for whatever reason this was automatically set to "upper field first" in my recent projects which is why voukoder didn't work. I don't know why vegas did that but the problem is fixed now. Thank you so much to all of you!
