Is it possible to use the Custom Vision service to analyze video files?

1. Yes

2. No

3. Only under specific conditions

4. Only for short clips

The correct answer is: No

The rationale behind the ability of the Custom Vision service lies primarily in its focus on image classification and object detection rather than video analysis. Custom Vision is designed specifically to work with still images, where you can train models to recognize and classify images based on visual content. While one might consider that videos comprise a series of images, Custom Vision does not inherently support the capability to process video files directly. Thus, attempting to use it for analyzing video content would not align with the primary function of the service, leading to the conclusion that it cannot handle video analysis as a standard feature. In the realm of video analysis, other Azure services and tools are more appropriate, such as Azure Video Analyzer or Azure Media Services, which are built to handle video streams and provide analysis functions suited for moving images. This distinction is essential in understanding the limitations of the Custom Vision service concerning video files.
