How to Dub a Video in Another Language | Metaglossia: The Translation World | Scoop.it

Dubbing your content in another language will make it more accessible. And you can do it yourself at home.

Dub tracks have long been a part of the film and television industry, but nowadays, indie creators are producing videos in different languages. It's well worth it too when you consider the new audiences you can reach when you offer a video in a different language.

Producing a dub track uses just about the same equipment that you probably already have if you create your own videos, and the process is also a lot easier than you might think.

Here's how to dub your video in another language.

How Dubbing Works

Dubbing a video is a fairly straightforward process that begins by creating a translation of the original dialogue. Using this script, a voice actor will work in small sections to record the new dialogue while watching the video.

The aim of a good dub is to match the new dialogue with the lip movements on screen. After the recording process is completed, a final round of audio editing ensures that the audio and video are perfectly synced.

Keep in mind that some platforms give you the option of uploading a separate audio track, so you don't need to upload two separate videos. YouTube is one platform making videos more accessible by giving creators the option to upload a dub track.

 

What You Need to Dub a Video in Another Language

There are only a few things you need to dub a video in another language, and they can be flexible depending on your budget and resources.

  • Microphone
  • Video/Audio Recording software
  • Translated copy of the original audio
  • Someone to voice the translated script

The main equipment required is a microphone and some recording software. The microphone you use can be a simple USB desk mic, and many video editors let you record audio directly into the session.

Translating your dialogue will pose a different challenge. Tools like Google Translate can help you get a rough draft prepared, but you might need to work with a native speaker to make it sound natural.

Finally, you will need to find someone—a paid voice actor, or a friend—who can speak a second language. There are many ways you can dub a video in another language, but if you happen to speak a second language already then you can do the job yourself.

 

1. Finalize Your Video

Before beginning the dubbing process, you need to have a completed edit of your video. Any changes made to the video after dubbing means you will have to go back and re-record any new dialogue that is inserted. This should be the first step in the dubbing process.

 

2. Transcribe and Translate the Dialogue

Next, you will need to transcribe the dialogue from the video into written text. This script is what you will be translating into another language.

Indie creators, and those working with a small budget, might be interested in exploring the best online translators available on the internet. They may not be perfect, but they can be a good starting point.

You should still work on fine-tuning the translation afterward to make it sound natural. Take some time to work with a native speaker to get it right. This could be the voice actor you are working with or someone else you know.

In addition, you will need to print a copy of the translated script for the voice actor to read during the recording process.

 

3. Set Up Your Equipment

Place your microphone in a quiet room, free from background noise. Then set up a computer or second screen close to the voice actor, so they can watch the video as they read the script.

In a professional studio, the voice actor will be in a separate room from the recording engineer. But for most people recording from home, you will probably be working in the same room. Here are some DIY hacks to improve your home studio if you're looking to improve the sound quality.

 

4. Set Up Your Recording Session

No matter what video/audio editing software you use, the dubbing process will require a similar setup. We will be using Davinci Resolve 18 (Free) to demonstrate, but the same will apply to any other recording software you use.

Start by importing your video into a new session by selecting File > Import Media, then drag the clip from the master clip area onto the editing timeline. Following that, click on the Fairlight tab located at the bottom of the screen to view the audio editing window.

Next, right-click on the head section of the original audio track, then select Add Track > Mono.

To change the microphone input, navigate to the Mixer panel and click on the input slot on the channel strip, then select Input.

From the window that appears, select the microphone input you want to use from the left-hand side and press Patch.

Finally, check that it's working by pressing the R button on the track to arm it for recording. You will be able to see the gain (volume) meter become active when you speak into the microphone.

 

5. Record Your Dub Track

Now, it's time to bring in your voice actor and begin recording the translated script. You might find it useful to watch the original video first to get familiar with the timing.

When you are ready for a run-through, mute the original audio track and press the record button in the timeline tools to start recording. Watch for the lip movements on screen and aim to voice the new dialogue at the same time. For accuracy, it's best to work on recording just a few phrases, or even single sentences, at a time.

Repeat this process until you have recorded the new dialogue for the entire video.

 

6. Sync the Audio and Video

To sync the audio with the video precisely right, you need to line the audio file exactly with what you see on screen. You can use a couple of tactics to achieve this.

In post-production, you can watch the video while listening to the audio, moving the audio file in the timeline a little to the left or right, until the dialogue begins exactly when the person on screen starts to speak.

Another method is to use the original audio track as a guide. When you zoom in on the audio file you can see the waveform of the audio. The mountain-like peaks that are visible represent the pattern of someone speaking. It's a good visual clue, showing you where you need to line up your dub track.

By the end of the editing stage, you should be able to watch the entire video from start to finish, with the new dub track perfectly in sync with the visuals.

 

7. Export Your Dub Track

When you are happy with the results, it's time to export the new dub track. To do this in DaVinci Resolve, right-click on the audio waveform in the timeline and select Export Audio Files.

These are the key export settings you need to change:

  • File format: WAV
  • Sample rate: Same as project
  • Bit depth: 24
  • Channel format: Interleaved
  • Export: Individual clips
  • From: Selected clips
  • Normalize: No normalization

You also have the option of exporting the entire video with the new dub track. Make sure that the original track is muted, then switch to the Deliver tab at the bottom of the screen. Adjust the export settings and press Add to Render Queue. When ready, hit the Render All button in the Render Queue list.

 

Indie Creators Can Produce Dub Tracks Too

Creating a dub track isn't just for people working in Hollywood. Individual creators can produce dub tracks in other languages too, and it's well worth it to make your videos more accessible to a wider audience.

Luckily, the process isn't too complicated, and you won't need any special equipment besides the video editing software you already use, a microphone, and someone who speaks a second language.
