Video transformation options as an Object instead of method chain

[ghost]

Hi, I currently in process of migrating from cloudinary-core to @cloudinary/url-gen, and one of the biggest challenge I am facing is around video transformations.

In my current implementation, I store all the transformations as an array of objects in database and use cloudinary.url method to inject the json for transformation.

const transformation = [
  {
    overlay: { text: "some text", fontSize: 40},
    gravity: "south",
    x: 100,
    y: 600,
    startOffset: "15",
    endOffset: "20",
    color: "#ffffff"
  }
]

const url = cloudinary.url("videoPublicId", {
  resource_type: "video",
  transformation,
  sourceTypes: ["mp4"]
})

Is there a way to do something similar using @cloudinary/url-gen? Or, do I have to resort to the method chain?

Any help is much appreciated!

Thanks!

Hi Prabs,

Thanks for reaching out. So you should be able to use createCloudinaryLegacyURL to migrate easily. Please have a look at https://cloudinary.com/documentation/javascript1_migration_guide#migrating_delivery_urls and let me know ho wyou get on.

Thanks Tom

Thanks Tom. It is definitely the right direction, but does not really solve my issue as the overlay still requires the function chain.

Hey @prabhatmyadbox

I just wrote this test which creates an overlay with a JSON

  it ('Accepts a JSON with an overlay', () => {
    const transformation = [
      {
        overlay: { text: "some text", font_size: 40, font_family: 'arial'},
        gravity: "south",
        x: 100,
        y: 600,
        startOffset: "15",
        endOffset: "20",
        color: "#ffffff"
      }
    ];

    const url = createCloudinaryLegacyURL("videoPublicId", {
      cloud_name: 'demo',
      resource_type: "video",
      transformation,
      sourceTypes: ["mp4"]
    });

    console.log(url);
  });

this is the output

Thanks for the the example Patrick.

I was finally able to get the desired result. And, I've realised where the error had occurred.

All my transformation keys had been converted to snakeCase (font_size, start_offset). But, for this function to work, the keys of transformation objects required to be camelCase while only the keys of overlay object needed to be snakeCase.

Thanks again!

Cheers!
