Vue.js video manipulation


After uploading videos to Cloudinary, they can be manipulated in many ways.

The syntax for transforming and delivering videos is generally similar to that for images, and you can apply the majority of available image transformations to video as well. For example, you can resize, crop, rotate, set video quality and format or use auto quality and/or auto format, add text or image overlays to your videos, and more.

There are also a number of special options you can use for transforming and delivering video content. For example, you can adjust their size, shape, speed, duration, quality, and appearance. There are also some features that are specific to audio.

This section introduces you to the basics of Vue.js video streaming and manipulation. For complete details on all video manipulation functionality, see Video manipulation and delivery and the Video transformations reference.

Video transformation functionality

In addition to transformation features that are equally relevant for images and video, such as resizing, cropping, rotating, adding text or image overlays, and setting video quality or format, there are a variety of special transformations you can use for video. For example, you can:

CldVideo component

You can deliver videos and specify video transformations using the cld-video (CldVideo) element, which automatically generates an HTML5 video tag including the URL sources for the main formats supported by web browsers (webm, mp4 and ogv), as well as a poster thumbnail image, which is automatically generated from a frame in the video. This enables the browser to automatically select and play the video format it supports. The video files are created dynamically when first accessed by your users.

As with cld-image, you can optionally include cld-transformation components to define chained transformations.

For example,

<cld-video cloudName="my_cloud" publicId="watchme">
  <cld-transformation overlay="text:arial_60:watchme" gravity="north" y="20" />

Will be rendered to:

  <source src=",l_text:arial_60:watchme,y_20/watchme.webm" type="video/webm">
  <source src=",l_text:arial_60:watchme,y_20/watchme.mp4" type="video/mp4">
  <source src=",l_text:arial_60:watchme,y_20/watchme.ogv" type="video/ogg">

For details, see the video tag documentation and the HTML5 Video Player blog post.

Video transformation examples

This section provides examples of using Vue.js code to apply some of the video transformation features mentioned in the previous section.

Example 1:

The following example resizes the dog video to 40% of its original size and rotates it by 20 degrees. It also adds a semi-transparent cloudinary logo in the bottom right corner, using a southeast gravity with adjusted x and y coordinates to reach the corner of the rotated video.

<cld-video cloudName="demo" publicId="dog" >
  <cld-transformation width="0.4" angle="20" />
  <cld-transformation overlay="cloudinary_icon" opacity="50" width="60" gravity="south_east" y="15" x="60" />

Example 2:

The following example adjusts the brightness of a skiing video, and sets its radius to max in order to give a telescope-like effect. It then appends a copy of the video in reverse, and the plays forward again, but in slow motion.

<cld-video cloudName="demo" publicId="ski_jump" >
  <cld-transformation overlay="video:ski_jump" flags="splice" effect="reverse" />
  <cld-transformation overlay="video:ski_jump" flags="splice" effect="accelerate:-50" />
  <cld-transformation effect="brightness:10" radius="max" />

Example 3:

The following example generates a video whose first 10 seconds will loop continuously in an HTML5 video player with default controls. The video is cropped to 360X480 using the pad cropping method, and it is generated at 70% quality to control file size, with a custom fallback message for browsers that don't support HTML5:

  fallbackContent="Your browser does not support HTML5 video tags." 
  loop="true" >
  <cld-transformation crop="pad" height="360" width="480" quality="70" duration="10" />

The above statement will be rendered to:

<video controls="controls" height="360" loop="loop" poster=",h_360,w_480,q_70,du_10/dog.jpg" width="480">
  <source src=",h_360,w_480,q_70,du_10/dog.webm" type="video/webm" />
  <source src=",h_360,w_480,q_70,du_10/dog.mp4" type="video/mp4" />
  <source src=",h_360,w_480,q_70,du_10/dog.ogv" type="video/ogg" />
  Your browser does not support HTML5 video tags.
