Live Audio and Video Enhancement

Last updated: 2024-07-11 16:24:05
    Live audio and video enhancement features include a variety of processing technologies, such as SDR to HDR conversion, frame interpolation, super resolution, overall enhancement, noise reduction, color enhancement, scratch removal, banding removal, detail enhancement, low-light enhancement, face enhancement, and text enhancement. These features are used for video quality remastering and significantly improve the subjective quality of audio and video.
    Live audio and video enhancement features can be used individually or in combination to improve live stream video quality in different scenarios. Billing for audio and video enhancement is based on the enhancement features used and the resolution and frame rate of the enhanced live stream video. The specific billing rules are described below.

    Notes

    The default billing mode for live audio and video enhancement is daily pay-as-you-go.
    Starting from 00:00 on October 1, 2023, the billing for audio and video enhancement features will be calculated separately based on the enhancement features used and the resolution and frame rate of the enhanced live stream video. Billing will start on October 2.
    When using audio and video enhancement features, additional fees for Top Speed Codec (TSC) Transcoding will be incurred. A TSC transcoding package can be used to offset the daily pay-as-you-go usage of TSC transcoding, but it cannot be used to offset the daily pay-as-you-go usage of audio and video enhancement.
    If you need to use live audio and video enhancement capabilities, please contact your Tencent Cloud sales rep or submit a ticket for evaluation and activation.

    Features

    Enhancement Feature
    Description
    SDR to HDR Conversion
    Converts SDR videos to HDR and increases the color depth to up to 10 bits to represent a wider gamut and display more color details.
    Frame Interpolation
    Inserts additional video frames between the original live stream video frames, resulting in a smoother and more visually pleasing viewing experience.
    Super Resolution
    Offers high-resolution models (default) and low-resolution models.
    Overall Enhancement
    Uses AI-based analysis to improve the overall image quality by balancing image textures, removing compression artifacts, and enhancing key details.
    Noise Reduction
    Removes the random noise introduced from the camera and the environment during live streaming while maintaining audio/video details.
    Color Enhancement
    Restores video colors that may have been distorted due to camera or storage issues and enhances colors so they are more pleasing to viewers.
    Scratch Removal
    Repairs damages in live streaming video, such as scratches and snowflake-like spots, improving the overall quality of the video.
    Banding (Artifact) Removal
    Repairs distortions caused by repeated compressions of videos during transcoding, such as blocking artifacts, ringing artifacts, color contamination, and mosquito noise.
    Detail Enhancement
    Enhances key details in live streaming video to improve video clarity and provide a better viewing experience.
    Low-Light Enhancement
    Automatically recognizes scenes and adaptively enhances video images to increase details and contrast in dark areas and improve image quality, especially in low-light scenes.
    Face Enhancement
    Enhances key facial features with the help of face recognition technologies.
    Text Enhancement
    Improves the clarity and readability of the text shown during a live stream.

    Billing Overview

    Billing Item: Live stream enhancement duration (prices vary based on enhancement features used and the resolution and frame rate of the enhanced video).
    Billing Rules: The default billing mode is daily pay-as-you-go. The fees are calculated based on the audio/video enhancement features used and the resolution and frame rate after enhancement. Your audio/video enhancement durations each natural day are multiplied by the corresponding unit prices.

    Billing formula

    Live stream enhancement duration fee = audio/video enhancement duration × unit price of the corresponding enhancement feature (determined by resolution and frame rate).

    Billing Example

    A 100-minute live stream on October 1, 2023 uses two audio/video enhancement capabilities: text enhancement and low-light enhancement. After TSC transcoding, the output live stream is in H.264 codec format, 1080p resolution, and 30fps. On October 2, 2023, your live audio/video enhancement billing will be as follows:
    TSC Transcoding Fee = 0.0443 (USD/minute) × 100 (minutes) = 4.43 USD;
    Text Enhancement Fee = 0.1411 (USD/minute) × 100 (minutes) = 14.11 USD;
    Low-Light Enhancement Fee = 0.0353 (USD/minute) × 100 (minutes) = 3.53 USD;
    Note:
    If you have a large-scale live streaming business, then a daily billing mode may not meet your needs. Please contact the Tencent Cloud sales team or submit a ticket for other billing options.
