Typical metadata - you can add other elements.

{"721":{
  "##policyID##": {
    "##ticker##": {
      "name": "##tokenName##",
      "image": "ipfs://<replace this with your Qid hash>",
      "nsfw": "False",
      "type": "image/jpg",
      "copyright": "Consider removing this line if it does not apply",
      "version": "1",
      "collection": "You put your collection name",
      "url": "https://www.metromermaids.com/",
      "twitter": "https://twitter.com/_mermada"
    }
  }
 }
}



Here is an example with a video file with a cover image:
{
  "721": {
    "##policyID##": {
      "##ticker##": {
        "name": "##tokenName##",
      "image": "ipfs://<thumbnail IPFS hash>",
        "files": [
          {
            "src": "ipfs://<mp4 hash>",
            "mediaType": "video/mp4",
            "name": "Video File Name"
          }
        ]
      }
    }
  }
}



Here is an example with a video file WITHOUT a cover image - don't do this...:
{
  "721": {
    "##policyID##": {
      "##ticker##": {
        "name": "##tokenName##",
        "files": [
          {
            "src": "ipfs://<hash>",
            "mediaType": "video/mp4",
            "name": "Video File Name"
          }
        ]
      }
    }
  }
}





Here are a couple of mediaTypes to show you how they might be used.
{
  "721": {
    "##policyID##": {
      "##ticker##": {
        "name": "##tokenName##",
        "files": [
          {
            "src": "ipfs://<hash>",
            "mediaType": "image/png",
            "mediaType": "image/jpeg",
            "mediaType": "image/gif",
            "name": "Pick an image type above, give this img a name in place of this line."
          }
        ]
      }
    }
  }
}

Here is an example with an image and a video both visible.

## Do not copy below this line ##
## Please read this entire guide ##

## Try using type: of image/jpg or image/gif
## like for example:
##  "type": "image/jpg",
##  "type": "image/gif",

## nfsw - please respect our community and set this to "True" if this

## Are you trying to make a series of NFT like "My NFT [01]" through
## "My NFT [50]" or some large set like this? Skip to the bottom for
## more information about that process. If you want to mint a large
## set of NFT under the same policy ID you should also skip to the end.

## If you are here to mint a NFT or FT (token) read the info below.

## First thing make sure your image tag above looks exactly like this:
## "image": "ipfs://QmXTeBCESNhphdCHvWyBugiAcZFxA6ZP7WYwxMu4QuNxzj",
## I used a random example above just to show what it should look like.
## Let's call the left side the "item" and the right side the "value"
## an example:
## "description": "A very long description"
## A value can not be longer than 64 characters long. If you have a long value you need
## break it into "an array". The format for this looks different.
## Example Array so you can have a long description. UPDATE: as of April 16th we tested
## the example with the long description as shown below and it is not currently showing
## up on the pool.pm page that we all use to view our NFT. It should be a quick fix
## for the page to accommodate showing descriptions from an array or value but it's up
## to them in the end what and how they display. For now, you can use the following
## format but it may not yet be displayed on the available tools.

"description": [
"A very long description can be ",
"placed within a bunch of little ",
"groups like this. As long as each group ",
"has a comma between and the last one does not!"
]


## Make sure than EVERY line ends with a , EXCEPT FOR THE LAST LINE! look above closely.
## If you wanted to use that example of Description with the multiple lines, you need to
## place a , after the ] or place the description as the last item in the group of items.
## Reach out to use using our Twitter or Telegram channels for quick support we can help

## LARGE MINT JOBS / MINT MANY UNDER THE SAME POLICY / SPECIAL REQUEST, ETC. ##
###############################################################################
We can help you mint a large set under the same policy and help to fulfill any
special requests regarding series or sets with special numbers, ie: [01] - [99].
Contact us using the channels above to get started, we can explain in more detail
what is needed. If you would like some example of metadata for a large mint set
take a look here:

An example where we add so many social media links that we have to mint in sets of 25.
The limitation of the large mint sets is that the metadata file must be less than 16kb.

Here is an example of a metadata file with the least amount of information, name and image.

To be clear, the examples of large mint jobs in the two links above are for working with us
directly and they will not currently work with this version of our mint tool.
