Compared with traditional image editing, VOD's real-time image processing feature has the following strengths:
Aspect
Traditional Image Editing
VOD Real-Time Image Processing
Processing steps
Multiple steps are required, including download, editing, and upload, which are time-consuming and laborious.
All operations are performed directly in the cloud, with no need for download or upload.
Ease of use
You need to have some knowledge of image editing to be able to use image editing software.
You can edit images in real time simply by specifying URL parameters.
Access speed
Image access and download through cloud storage URLs are slow, affecting the user experience.
VOD uses CDN to accelerate global image delivery, so that you can get the processed images in very little time.

Use Cases
