from dotenv import load_dotenv
load_dotenv()


import cloudinary


config = cloudinary.config(safe=True)


print("Your Cloudinary Credentials:")
print(config.cloud_name, config.api_key)Code language: PHP (php)

The following examples present a gamut of video modifying and optimization potentialities utilizing Python and Cloudinary. The objective is to offer you a small style of what you are able to do with Cloudinary, present you methods to implement the edits, and encourage you to begin creating your individual. 

You can check out every instance individually, and you possibly can see a full code sandbox under or on GitHub.

The following operate returns the URL of an authentic video saved in Cloudinary:

def getOriginal(publicId):
 originalURL=cloudinary.CloudinaryVideo(publicId).build_url()
 return originalURLCode language: PHP (php)

The public ID, the video’s distinctive identifier, is handed in to operate. Cloudinary returns the video’s URL, which can be utilized to ship the video in its authentic type.

Here’s the video:

The following examples show how to edit the original video by adding a few parameters.

This code snippet edits the video in numerous ways: 

Resizing and cropping: {"aspect_ratio":"4:3", "crop":"fill", "y":"100", "width":"400"}

Trimming: {"duration": "5"}

Concatenating a cropped, resized, and trimmed video stored in Cloudinary with public ID docs/video_features_tutorial/makeup:

{"duration": "5", "flags": "splice", "overlay": "video:docs:video_features_tutorial:makeup"},
{"aspect_ratio": "4:3", "crop": "fill", "y":"130", "width": "400"},
{"flags": "layer_apply" }

Adding background music, stored in Cloudinary with public ID video_features_tutorial/romeo_and_juliet:

{"overlay": "video:docs:video_features_tutorial:romeo_and_juliet"},
{"flags": "layer_apply"}

Adding a watermark, stored in Cloudinary with public ID cloudinary_icon, resized and placed in the north east corner or the video: 

{"overlay": "cloudinary_icon"},
{"width": "40", "x":"10", "y":"10" },
{"flags": "layer_apply", "gravity": "north_east"}

Adding an SRT file stored in Cloudinary with public ID video_features_tutorial/captions.srt as subtitles: 

{"overlay": {"resource_type": "subtitles", "public_id":
"docs/video_features_tutorial/captions.srt"}},
{"flag": "layer_apply" }

def concatenated():
 videoURL = cloudinary.CloudinaryVideo("docs/video_features_tutorial/hair").build_url(transformation=[
   {"aspect_ratio":"4:3", "crop":"fill", "y":"100", "width":"400"},
   {"duration": "5"},
   {"duration": "5", "flags": "splice", "overlay": "video:docs:video_features_tutorial:makeup"},
   {"aspect_ratio": "4:3", "crop": "fill", "y":"130", "width": "400"},
   {"flags": "layer_apply" },
   {"overlay": "video:docs:video_features_tutorial:romeo_and_juliet"},
   {"flags": "layer_apply"},
   {"overlay": "cloudinary_icon"},
   {"width": "40", "x":"10", "y":"10" },
   {"flags": "layer_apply", "gravity": "north_east"},
   {"overlay": {"resource_type": "subtitles", "public_id": "docs/video_features_tutorial/captions.srt"}},
   {"flag": "layer_apply" }])
 return videoURLCode language: JavaScript (javascript)

Here’s the edited video:

Here’s an example of non-linear editing. You can apply one video over the other as an overlay to have them play at the same time: 

def overlay():
 videoURL = cloudinary.CloudinaryVideo("docs/sdk/go/exercise1").build_url(transformation=[
   {"crop":"scale","width":"300"},
   {"overlay": "video:exercise2"},
   {"crop":"fit","width":"80","border":"1px_solid_white"},
   {"flags": "layer_apply","gravity":"north_east","start_offset":"2.0"}
   ])
 return videoURLCode language: PHP (php)

Here’s the video:

In this example, the blue background in this product video is switched to a beach scene:

def removeBackground():
 videoURL=cloudinary.CloudinaryVideo("docs/sunset_waves").build_url(transformation=[
 {'width': 500, 'crop': "scale"},
 {'overlay': "video:docs:bluescreen_watches"},
 {'flags': "relative", 'width': "0.6", 'crop': "scale"},
 {'color': "#0e80d8", 'effect': "make_transparent:20"},
 {'flags': "layer_apply", 'gravity': "north"},
 {'duration': "15.0"}
 ])
 return videoURLCode language: PHP (php)

Here’s the video:

When you crop videos, especially in bulk, you risk cutting out the important parts and ruining the video. Cloudinary prevents this from happening by using AI to make sure that the main subjects of the video are followed throughout. 

Cropping this video causes the gymnast to move in and out of view because, the crop by default just captures the center of the video:

def getGAutoOrig():
 videoURL = cloudinary.CloudinaryVideo("olympic_gymnast.mp4").build_url(transformation=[
   {"crop":"fill","width":"120","height":"300"}])
  return videoURLCode language: PHP (php)

Here’s the video, cropped with out AI utilized. Notice the gymnast doesn’t keep within the body all through:

Adding the gravity:auto parameter ensures that the gymnast remains in focus:

def gAuto():
 videoURL = cloudinary.CloudinaryVideo("olympic_gymnast.mp4").build_url(transformation=[
   {"crop":"fill","gravity":"auto","width":"120","height":"300"}])
 return videoURLCode language: JavaScript (javascript)

Cloudinary can reduce the size of your videos to improve your web performance with:

• f_auto: Delivers the video using the best format for the requesting browser.
• q_auto: Delivers the video using the optimal compression that balances the smallest size without sacrificing visual quality.

def fqAuto():
  videoURL = cloudinary.CloudinaryVideo("docs/sunglasses").build_url(transformation=[
    {"fetch_format":"auto","quality":"auto"}])
  return videoURLCode language: PHP (php)

Here’s the optimized video:

Cloudinary can ensure that your videos are delivered with the least interruption, at every second and from any browser, using adaptive bitrate streaming. 

def autoStreaming():
  videoURL=cloudinary.utils.cloudinary_url("docs/waterfall.m3u8", streaming_profile="auto", resource_type="video")
  return videoURLCode language: PHP (php)

Here’s the streaming video:

You can see all these examples built-in in a full Python program on this code sandbox: 

These are simply among the Python video modifying and optimization potentialities that Cloudinary can provide. Cloudinary offers related modifying capabilities to Python libraries akin to MoviePY, Scikit-video, and VidGear, together with some Cloudinary-unique capabilities besides. Leverage Cloudinary’s smart-cropping, optimization, and adaptive bitrate streaming to enhance your web site’s efficiency and person expertise.
