idvb uses script tokens so you won’t see any metadata and the scripts will look like that. The tokens/scripts are downloaded specifically for the device you had connected when you downloaded them and won’t work on any other device.
If my understanding is correct they work by connecting to the Handy database which sends the movements directly to your Handy instead of using the actual script file. You use the script the exact same way you would use any other one, you just can’t see the script if you wanted to examine it.
FYI, the one’s I’ve tried haven’t been very good, obviously your mileage may vary but I don’t think they’re hand crafted, maybe a combination of human and ai made.
