Short-form drama AI voiceover translation
Dubbing translation involves identifying the voice in the original video, generating text in the target language, and then creating a dub that matches the rhythm of the characters and the visuals.
Automated results can reduce production time, but character names, titles, plot twists, and cultural expressions still require manual review.
- Select a representative short play episode.
- Confirm that you have the rights to translate and distribute.
- Upload the video and wait for the media to be parsed.
- Select the target language you need.
- Generate a preliminary draft of the dubbed translation.
- Check the pronunciation and tone of the character.
- Check the character relationships and key lines.
- Enable lip alignment as needed.
- Listen to the full version and note down the issues.
- Process in batches after confirming the effect.
Lip alignment
Lip synchronization adjusts the movement of the characters’ mouths in accordance with the voiceover in the target language, thereby making the dubbed audio more in harmony with the visuals.
| Scene | Effect impact | Inspection method |
|---|---|---|
| Close-up from the front | The differences in lip shape are the most noticeable. | View the opening and closing of the mouth frame by frame. |
| Side profile or obstruction | There is limited available information for the model. | Ensure that the face is not distorted. |
| Multi-person camera view | It’s possible that the wrong person was matched. | Confirm the speaking role for each sentence. |
| Quick editing | Sentences may span across camera shots. | Check the cut points and sound continuity. |
| Exaggerated expression | Coordination between mouth movements and facial expressions | Ensure that the expressions remain natural. |
| Low-resolution materials | Lack of facial details. | First, test the usability with a short video. |
What are hard subtitles?
Hard subtitles are text that is embedded directly into the video image; they cannot be turned off or replaced as easily as soft subtitles such as SRT.
To create a clean overseas version, it is necessary to identify the subtitle area and reconstruct the original image that was covered by the text.
| Subtitle type | Features | Handling method |
|---|---|---|
| Soft subtitles | Separate subtitle track or file | Replace directly or turn off |
| Hard subtitles | The text has been written on the screen. | AI removes and fixes the background. |
| Speech without subtitles | Only audio content | First, use speech recognition to generate subtitles. |
| Dynamic animated text | The position and style keep changing. | Segmented testing for identification and repair |
Hard subtitle removal
ZhiSheng ZiYingHui can identify the already recorded subtitles and use information from adjacent frames to repair the parts of the image that are obscured by those subtitles.
- Static backgrounds are usually easier to fix.
- Rapid movement increases the difficulty of reconstruction.
- When subtitles cover the characters, it is necessary to check carefully.
- Complex textures may exhibit smearing or flickering.
- Multi-line and dynamic subtitles should be tested via sampling first.
- Even after repair, it is still necessary to preview each shot manually.
Image repair inspection
- Select segments that contain people, movement, and complex textures.
- Submit a short clip for subtitle removal.
- Pause to view the location where each subtitle appears.
- Check whether there are repeated textures in the background.
- Check whether flickering occurs in adjacent frames.
- Check the edges of the character’s clothing and face.
- Compare the clarity of the original footage with that of the clean image.
- Submit the entire series after meeting the requirements.
Batch processing of short dramas
Batch processing is suitable for multi-episode series, but it is necessary to first test the language, subtitle areas, audio, and output parameters using a typical single episode.
- Create a unified character list for each series.
- Fix role names and translation rules.
- Create a glossary of terms for brands, locations, and props.
- Standardize frame size, clarity, and audio specifications.
- Create traceable file names based on the episode number.
- Multiple episodes are randomly selected from each batch for review.
- If a systematic issue is detected, the task should be suspended immediately.
