Day 12: Let's talk about how to achieve video transparency. This should be mad fun!!!!

A typical case study is how you'd like to have a nice background or that of a certain color in your video because you hate the background or you just want to make it cool.

#25DaysOfMediaMagic
With @cloudinary, this is a walk over.

There's a make transparent feature available to immediately remove the background of a video. It is `e_make_transparent`.

Now, take a look at this video. #25DaysOfMediaMagic
@cloudinary We will remove that ugly, plain, depressed background and replace it with a new background in the video.

How?

You need to do this with the `e_make_transparent` feature and overlay the new video with the initial video.

This is the new video that we want to make the background
@cloudinary Now, check this out: 😅😂😎

Mad oh!!! #25DaysOfMediaMagic
@cloudinary How did we accomplish that?

Check out the code in the image; The URL way to the left, and the Node.js way to the right.

I'll explain the code in the next tweet. #25DaysOfMediaMagic ImageImage
@cloudinary This is the wordy explanation of how the code accomplishes the video background swap.

- Specify a start_offset, known as `so`
- Apply the initial video as an overlay, known as `l_video:docs:<id-of-video>`
- Apply the make_transparent effect, known as `e_make_transparent`
@cloudinary - Add a color if you like, known as `co`
- Specify a width (optional), known as `w`
- Specify the duration of the final video with `du`
- Add the public id of the video of the new background video.

That's all.

You must have noticed a lot of `known as`. #25DaysOfMediaMagic
@cloudinary The `known as` just refers to the short alias used in the URL form for each of the transformation parameters I specified in each sentence
