In this guide, we’ll cover:

How to begin the proofreading process

How to upload your video file

How to select your proofreading and translation options

How to access your proofread video

How to review your video and make script edits

How to generate your updated video for use

How to begin the proofreading process

Begin by clicking the ‘Create video’ button and select the ‘Video Translation’ option.

Once in the translation tool, either upload your video to be proofread or click ‘Use video URL’. If you choose the video URL option, you can use either a YouTube or Google Drive video link.

After uploading your video or inserting a link, click ‘Create proofread.’

Select your video proofreading and translation options

Once you’ve uploaded your video or inserted your link, you’ll be given several options.

The tool will auto-detect the language featured in your video, or you can set it yourself. You’ll also need to select the output language for the video you’re translating. You can also set the number of speakers that will be featured and your brand voice. Another option to consider is to ‘Enable dynamic duration,’ which gives HeyGen the power to adjust segment durations to improve translation and video quality. Also, you can use the ‘Translate to text’ feature to translate all visible text in your video to your target language.

To enhance the accuracy of your translated content by clicking ‘Upload SRT/ASS’ and upload your original subtitle files.

Once your selections are made, click ‘Submit,’ and your video will begin processing. The processing speed depends on the size of your video and may take a bit to complete.

Access your proofread video

Your processing video will show up in your video library. You can keep track of its progress there.

Then, when it’s ready, you’ll be able to review your video

Review your video and make script edits

HeyGen will also automatically translate your video’s script into the selected language.

Access your newly proofread video in your library and review your proofread script. Click into it and you can make the changes you’d like to perfect it.

Also, within the script text box, you can select a new voice to narrate your video or create a new voice clone if you’d like.

You’ll love this feature because it allows you to use a voice with more depth, emotion, excitement, intensity, or whatever tone you’d like to set.

We highly recommend that you preview your entire video so that you can catch errors in pronunciation. All you have to do is hit the ‘Preview’ button and give your video a watch.

Additional features you should know

There are a few other features that you should know about as you work to finalize your scripts.

The first is the ability to download your scripts for review. Click the three dots at the top of the script editor.

You can download your script in Excel, as a Translation SRT, or as the Original Transcript SRT.

You can then make edits to your script and upload them back into HeyGen when you’re ready by clicking the same three docs and choosing ‘Upload scripts.’

Also in Proofread, you can highlight any word in your script, and it will show you the phonetic pronunciation of any word.

You can also add a pause by clicking on the time icons on the right of the script. When you click it, it will automatically copy the icon and you can place it anywhere in your script.

Generate your updated video for use

Once your edits have been made, and you’re happy with your video, you can click ‘Generate result’ and finalize it.

Before you generate your result, you can select ‘Include captions’ if you’d like and ‘Translate audio only’ if you’d prefer that people within your video not lip-sync your script.
