We can see the transaction at https://mempool.space/zh/address/bc1p5k6m3rsnr98mwd7qzsw9qyz0awxffms30axtlpeygkx3hchuusasz5ceuy. Now the NFT is in the second output of the tx. The NFT seems like a video. But I don't know how can store a video in just about 50KB space. Who can tell me is it really a video?
