Something has been bugging me and that was using BOB with 30 fps footage, technically recombining 2 consecutive fields should always give you a complete frame, but most of the times you get motion blur. In this video I went out of my way to remove it from everywhere I could using a technique passed down in the Armstrong family for generations, with quite decent results.

What I did was I applied a half transparent 1/60th of a second late filter on the footage and made sure that the part that shows a frame without motion blur was always every 1/30th of a second away from the next full frame on the timeline in Sony Vegas as in the timer on the left shows the time and the last number is frames. it took some frame cut outs, which lead to more frame cut outs but in the end I got a nice looking video out of it.

The frame cut outs happen mostly whenever the game switches between 2 framerates, so the menus and the timing minigame. it also happens when the game has to think, like when enemy attacks or when the battle starts... and every time you adjust one all of the ones after it that may or may not have been in correct spot change to the opposite...

I cant exactly recommend going through all of the cutting out. I'd just say, find the configuration aka starting frame in which you run into the least motion blur overall in the video and leave it be, that is if you really want it to be in 30 frames. I'll make another video to show off what happens if you use the filter and still keep it at 60 while the actual framerate is at 30
