Introduction
Media quality inspection uses advanced AI algorithms to assess the quality of video frames and audio and generates an overall quality score. The assessment detects problems including video shaking, ghosting, blur, low light, overexposure, glitch, and audio abnormalities. According to the detection results, you can quickly locate and fix audio/video quality issues, improving the efficiency of media restoration.
Inspection Item | Description |
Video shaking, ghosting | Detects problems such as shaking and ghosting in video images caused by unstable camera setup and environment during video shooting. |
Video image blur | Detects blur caused by shooting conditions or repeated transcoding or compression. |
Video image low light, overexposure | Detects low brightness and contrast (which result in dark or overexposed video images) caused by poor shooting environment or hardware limitations. |
Video image glitch | Detects glitch problems in video images caused by some unknown factors during shooting, saving, and transferring. |
Black or white bars | Detects black/white bars and black/white screens introduced during shooting, saving, or transferring. |
Video image noise | Detects random noise introduced by the camera or due to poor shooting environment. |
Video pixelation | Detects pixelated video images. |
QR codes, mini program codes, and barcodes | Detects QR codes, mini program codes, and barcodes in video images. |
Video image quality evaluation | The system performs no-reference quality assessment on a video segment and generates a score. If the score is lower than the threshold you specify, the assessment result will be sent to you. |
Audio
| Detects audio issues such as no sound, low audio volume, and audio popping. |
Use Cases
You can use VOD's media quality inspection feature to assess the quality of user-generated videos, restore old videos, generate 4K videos, and more.
Use Case | Description |
UGC | The quality of short videos on UGC platforms varies. To increase click-through rates, platforms can use VOD’s media quality inspection feature to quickly detect and fix quality issues in multiple videos. They can also give recommendation scores to videos based on their quality and, if low quality is detected, block the video or ask users to upload a higher-quality version. This can encourage users to create higher-quality videos, leading to better overall content quality on the platform. |
Live broadcast platform | For high-value live content, platforms often record and edit content so it can be live streamed later. The media quality inspection feature allows platforms to quickly identify low-quality video segments, which can either be restored or removed, improving the overall quality of the video. This helps platforms attract more viewers and generate higher revenue. |
Old video restoration | Artifacts and scratches are common in old videos due to the limitations of camera technologies at that time. VOD's video quality inspection feature can detect quality issues in old videos, making it easier to restore video quality. |
