Like it or not, it's a SMPTE standard (doesn't make it "right", but a whopping lot of people abide by it, therefore it has relevance in real life), which specifies to either wrap every field (i.e. half-frame) into its own KLV set (labeled as I1) or both into one (labeled ad I2). The first produces a valid Picture Item using a pair of its KLVs, the second only needs one, obviously. I've seen I1 more often than I2. (There's a third version for "interlaced essence" called F1 which I've not yet had to deal with.)
