Scenarios
Smart erase enables blurring, mosaic, or seamless processing of elements like logos, subtitles, human faces, and license plates in video images. This feature is widely used in multiple fields, such as short drama platforms, short video platforms, cross-border e-commerce, and independent media studios. For pricing, see billing instructions in Smart Erase. You can create custom smart erase templates and preset different processing parameters for different application scenarios for future use.
Prerequisites
1. You have registered a Tencent Cloud account.
2. You have enabled Media Processing Service (MPS) and logged in to the MPS console.
Template Configuration Guide
Go to the Template Management > Media AI Template > Intelligent Erase page. The system provides several preset templates that you can use directly. You can click Create Intelligent Erase Template to create a custom template.

Configuration Guide for "Subtitle Removal"
When the erasing type is Subtitle removal, the following configurations are supported.
﻿
Configuration Item
Description
Erasing Method
Automatic erasing: Automatically recognize existing text areas in the entire video image by using Optical Character Recognition (OCR), and erase the text in the area specified by "Automatic Erasing Area". Automatic erasing is recommended for batch processing.
Specified area erasing: Use specified area erasing to minimize missed erasing issues if the subtitle position in the video image is fixed. The system directly erases subtitles in the "target erasing area" without automatically recognizing or erasing text content in other areas of the video image. Please specify the complete "target erasing area".
Subtitle Removal Model
Different models affect the removal effect to a certain extent.
Standard Edition (recommended): Usually, this edition is recommended. It is applicable for videos with standard subtitle styles, providing a better removal effect and superior detail restoration.
Area Edition: It is applicable for subtitles with special styles (such as background shadows, cursive fonts, and dynamic effects), with a larger erasing area but poorer removal effect compared with the Standard Edition.
Example:
Left: original video. Middle: processing effect of the Area Edition. Right: processing effect of the Standard Edition. If the subtitle style in your video is similar to that in this example, choose the Standard Edition.
﻿
Left: original video. Middle: specified target erasing area in the green box. Right: erasing effect of the Area Edition.
﻿
Erasing Method: Automatic Erasing
The system automatically identifies existing text areas in the entire video image by using OCR and erases the text in the area specified by "Automatic Erasing Area". Automatic erasing is recommended for batch processing.
Configuration Item
Description
Auto Erasing Area
Preset area: Lower central area of the video image.
﻿
Custom: If your video is similar to the example below and has other text content in the lower central area that does not require erasing, you can specify the approximate position of subtitles to reduce incorrect erasing issues.
Left: original video. Middle: text content at the bottom not erased after the central subtitle position is specified for "Automatic Erasing Area". Right: text content at the bottom erased if "Preset area" is selected.
﻿
Add Erasing Area
Advanced feature. Once it is enabled, you can add rectangle boxes. The system erases text content in these boxes on the basis of automatic erasing. This feature is mainly used to specify fixed text areas for erasing to reduce missed erasing issues.
In the following example, except for the "automatic erasing area" (subtitle position), two additional "erasing areas" (the warning text area in the upper left corner and the show title area at the bottom) are added to ensure that text in these fixed areas is erased.
Green box: automatic erasing area. Red box: added erasing area.
﻿
OCR Extract Subtitles
Advanced feature. Once it is enabled, the system can perform subtitle removal and extract subtitle text through OCR.
Note:
When multiple text areas exist in the video image, the system selects only one text area for extraction and erasing, typically the most stable one that exists for the longest time.
Only text in the "automatic erasing area" is identified. Text in other areas is not extracted or erased.
Erasing Method: Specified Area Erasing
If the subtitle position in the video image is fixed, you can use specified area erasing to minimize missed erasing issues.
﻿
Configuration Item
Description
Target Erasing Area
After the target erasing area is specified, the system directly erases text content in this area and does not automatically recognize or erase text content in other areas of the video image. Please specify the complete "target erasing area". Example:
Left: original video. Middle: specified target erasing area in the green box. Right: erasing effect (using the Standard Edition model of subtitle removal).
﻿
Configuration Guide for "Watermark Removal"
When the erasing type is Watermark removal, the following configurations are supported.
﻿
Configuration Item
Description
Watermark Type
Logo removal means erasing graphic content such as logos, icons, and user profile photos in video images. It supports two modes: Basic Edition and Advanced Edition.
Basic Edition: provides a basic blurring effect. It is cost-effective and applicable for animations or videos with a clean background. The "Smart Erase (Logo Removal - Basic Edition)" fee is charged.
Advanced Edition: provides a better erasing effect. It is applicable for reality-style videos such as short dramas. The "Logo Removal - Advanced Edition" fee is charged.
Erasing Method
Automatic erasing: AI models are used to automatically recognize and erase logos in full-screen video images, supporting both static and dynamic logos.
It only supports processing logos in the MPS model library, which currently contains over ten common Internet logos. For logos not in the MPS model library, the customized training service is provided, which incurs a separate model training fee.
Specified area erasing: For static logos with a fixed position, it is recommended to use specified area erasing to reduce missed or incorrect erasing issues. For logos not in the MPS model library, if the position is fixed, specified area erasing can also be used. No additional model training fee is charged.
Example:
Red box: dynamic logo that is constantly moving. It is recommended to use automatic erasing (model training required for uncommon Internet logos). Green box: static logo with a fixed position, which can be removed by using specified area erasing.
﻿
Erasing Method: Automatic Erasing
Configuration Item
Description
Auto Erasing Area
Automatic detection: The system automatically detects and erases watermarks that appear in the full-screen video image.
Custom: You can specify the approximate position of the logo. The system filters out logos outside this area during automatic erasing, thereby protecting other areas of the video image that do not require erasing.
Add Erasing Area
Advanced feature. Once it is enabled, you can add rectangle boxes. The system erases watermarks in these boxes on the basis of automatic erasing. This feature is mainly used to specify fixed watermark areas for erasing to reduce missed erasing issues.
Example:
Green box: automatic erasing area (globally recognize and erase common logos in the MPS model library). Red box: added erasing area (profile photo in a fixed position).
﻿
Erasing Method: Specified Area Erasing
For static logos in a fixed position, it is recommended to use specified area erasing to reduce missed or incorrect erasing issues.
For logos not in the MPS model library, if the position is fixed, specified area erasing can also be used. No additional model training fee is charged.

Configuration Item
Description
Target Erasing Area
After the target erasing area is specified, the system directly erases the logo in this area and does not automatically recognize or erase logos in other areas of the video image. Please specify the complete "target erasing area".
