Any data between last tile and frame end is vendor-specific metadata: [psim record] 4 be32 size + "psim" + pascal string + payload <more records, if any>, or: [eomd] 4 be32 size=8 + "eomd" fourcc (end of metadata) [padding] zero-fill to next-frame alignment

Known records (feel free to extend): com.panasonic.Semi-Pro.optical_correction (IEEE doubles): R - radial polynomial? + padding: [ k0, k1, k2, k3, pad0, pad1 ] G, B: same Trailer: optical center in normalized frame coords: [ x, y ]
