Blackmagic Intensity Pro - 720x486 to 720x480

Pretty much just making this quick post to remind myself what to do when handling SD 720x486 material from the Intensity Pro/Shuttle. Hopefully it helps someone.

The OCD inside me wants the processed output from these devices to be 720x480 so it falls in line with other capture cards. You would think this would be an easy solution, right? Just crop 3 pixels from the top and 3 from the bottom... nope. According to this post, that will reverse field order (instead of being TFF it will be BFF). Personally I can't really see how it would (maybe program specific?) but let's not dwell on that.

The correct way to go from 720x486 to 720x480 is to crop 2 lines from the top and 4 from the bottom. Check the second post here. Other sources I've read seem to back this up.
