The number of every clip is a "smart" code. Different parts of the number have defined meanings. the two right-most digits is a serial number within the same staging. The third digit from the right is the hotness level. The remaining 1-3 digits are a staging code that cossets of flag bits. For example, clip a1464_1024404.vghd has a staging code of 1024, a hotness of 4 (Full Nudity) and is the fourth clip within the 1024 group. The 1024 means this clip is a Swing. Any clip with a staging >= 1024 is a swing until Totem defines a meaning for bit 2048.
