Video translation uses artificial intelligence (AI) and machine learning (ML) to efficiently and accurately convert video content from a source language to one or more target languages, making it accessible to a global audience. This technology covers both subtitle translation and speech translation to ensure a natural and consistent viewing experience. By breaking down language barriers, video translation enriches educational content, enhances entertainment experiences, and promotes cross-cultural communication.

Features

The video translation service, part of Intelligent Media Services, provides efficient and professional video translation. It supports both subtitle-level and speech-level translation, and will eventually support face-level translation.

Translation level

Description

Subtitle-level

Subtitle-level translation extracts subtitle text from a video and translates it to the target language. The translated subtitles can be embedded in the video or provided as a separate subtitle file.

Speech-level

Speech-level translation converts the spoken audio in a video to text, and then translates the text to the target language. The translated text can be synthesized into speech in the target language to replace the original audio.

Create a video translation job

  1. Log in to EchoMind.

  2. In the left-side navigation pane, choose Media Processing > Video Translation.

  3. On the Video Translation tab, click Create Job.

  4. Configure the following parameters:

    • Job type: Subtitle translation or speech-level translation.

    • Source file type:

      • Subtitle-level translation: Supported source files are video and subtitle files.

      • Speech-level translation: Supported source files are video and audio files.

    • Subtitle source:

      • Optical Character Recognition (OCR): Extracts subtitle text from the video by using OCR.

      • Subtitle file: Translates a subtitle file that you provide.

    • Translation languages: Select the source and target languages.

    • Advanced settings: Configure options such as removing the original subtitles from the translated video or setting the output subtitle type.

      • Monolingual subtitles: Provides subtitles only in the target language, suitable for a single-language audience.

      • Bilingual subtitles: Displays subtitles in both the source and target languages, ideal for multilingual audiences or language learning.

      • No subtitles: Does not add any subtitles to the video, which is useful if subtitles are not required or if you plan to use another language conversion method.

  5. Upload source file.

    Click Add Source File to upload the video, subtitle, or audio file that you want to translate.

  6. After confirming all parameters, click Next to configure the job.

    The job settings page contains three configuration sections (Target Subtitle Style, Optical Character Recognition, and Subtitle Removal), as well as options to save or apply templates. The basic subtitle style settings include options such as line wrap (for example, breaking lines at spaces), text width, character spacing, line spacing, style (italic, bold, or underline), and opacity. You can also enable a shadow or glow effect.

    You can customize the target subtitle style, Optical Character Recognition, and subtitle removal settings. You can also save the current configuration as a template or apply it to all related jobs to streamline future configurations and improve efficiency.

    Parameter

    Description

    Target Subtitle Style

    Adjust basic subtitle styles and apply artistic text effects.

    • Basic subtitle style:

      • Font size: Choose a font size that suits the video dimensions and your preferences.

      • Font color and outline: Customize the font color and outline to ensure subtitle readability against different video backgrounds.

      • Position and alignment: Specify the subtitle position and alignment to meet various visual requirements.

    • Artistic text: Apply various artistic text effects to subtitles to capture the audience's attention.

    Optical Character Recognition (OCR)

    • Smart recognition: Automatically extracts subtitle text from the video by using advanced OCR and Natural Language Processing (NLP) algorithms.

    • Manual selection: If smart recognition is not accurate, for example, when subtitles blend with the background or use non-standard fonts, you can manually select the subtitle area for recognition.

    Subtitle removal

    • Do not remove: Keeps the original subtitles in the video and generates only a new, translated subtitle file.

    • Smart recognition: Uses intelligent algorithms to detect and remove the original subtitles from the video.

    • Manual selection: Manually specify the subtitle regions to be removed.

  7. Click Start Translation Job.
