With instant video dubbing, you can submit videos to be instantly translated and dubbed using your existing custom LILT models to increase quality and brand accuracy. This workflow is ideal for short-form videos with one speaker, such as product training videos, launch announcement, or internal communications. Instant video dubbing takes only minutes to receive a fully dubbed video! This is a self-service feature for instant video translation & dubbing, as compared to the wide range of other multimedia LILT supports through its verified translation services offering.

​
Submitting a video for instant dubbing

  1. Select Translate on the LILT homepage, and select “Video file”.
  2. Turn off the toggle for “Send for Human Verification”, as this is an instant dubbing workflow. Set the other parameters for your upload:
    1. Source language
    2. Target language
    3. Dubbing - Toggling this on will dub your video into the target language and will give you an option to select a voice for your dub. You can listen to each voice before selecting one.
    4. Review required - This sets whether or not you would like to review the extracted and translated text before sending the video for dubbing.
    5. Select your model under Advanced options.
  3. Upload your video file. You can also optionally add a subtitle file, which will bypass the text extraction step. If you don’t add a subtitle file, LILT will extract text to be translated and dubbed. Click on “Translate and dub”.
  4. If you didn’t add a subtitle file, you will be asked to review the extracted text. Click “Next”.
  5. Review and make any necessary changes to the extracted text and timestamps. Once you’re satisfied with the source text, click on “Mark reviewed”. Click on “Translate” to instantly translate the content.
  6. LILT will then use your selected custom model to instant translate the video.
  7. After the instant translation is completed, review and make any changes to the instant translated text. This might involve adjusting words per caption, or broken words/phrases. Once you are satisfied with the translated text, click “Mark reviewed”, then “Send for dubbing”.
  8. Your video will be dubbed into the target language selected.
  9. Once the dubbing has been completed, you can view your dubbed video in the platform. You also have options to download the Dubbed video (.mp4) and the subtitle file (.srt).
    1. Please note: LILT does not support re-integration of the subtitle file into the dubbed video at this time.
  10. At any point during the text extraction, instant translation, or dubbing, you can leave the instant video dubbing screen. Progress notifications will appear in your notification tray when the step completes and you can access the in progress project.

Best practices

  1. Managing segment lengths is key to a high-quality dub. Try to match the length of your source and target segments as much as possible. You can copy/paste text from one segment to another to preserve the instant translation. Additional considerations:
    1. Keep the subtitles concise: Maximum 2 lines per subtitle.
    2. The standard reading speed is 12 words per subtitle.
    3. Subtitle lines should end at natural linguistic breaks.
    4. Do not break a person’s name or title from within a line.
    5. Always start sentences in capital letters.
  2. After instant translation, you can use the play button next to each target segment to hear what the segment sounds like using your selected voice.
    1. If you hear the voice speaking very quickly, consider shortening the text in the target segment, or extending the time stamp for the segment.
    2. If you hear the voice speaking very slowly, consider lengthening the text in the target segment, or shortening the time stamp for the segment.
