Question 1

How does voice cloning work?

Accepted Answer

DubSync uses AI to analyze the speaker's voice characteristics — pitch, tone, accent, and emotion — from the original video. It then generates new speech in the target language that preserves these characteristics, so the dubbed version sounds like the same person speaking a different language.

Question 2

What video formats are supported?

Accepted Answer

DubSync supports MP4, MOV, AVI, and other common video formats. The maximum file size depends on your plan: 100MB for Free, 500MB for Starter, 2GB for Pro, and 5GB for Enterprise.

Question 3

How long does dubbing take?

Accepted Answer

Most videos are processed in 2-5 minutes. A typical 10-minute video takes about 3 minutes to dub into one language. Processing time may vary based on video length and server load.

Question 4

Is there a free plan?

Accepted Answer

Yes. DubSync offers a free plan with 5 minutes of dubbing per month, 2 target languages, and 720p output. No credit card is required to get started.

Question 5

How accurate is the lip sync?

Accepted Answer

DubSync uses AI lip-sync technology to automatically adjust mouth movements to match the new audio. Our users report a 95-98% accuracy rate, making it nearly indistinguishable from native speech.

Question 6

Can I edit the translation before dubbing?

Accepted Answer

Yes. After the AI generates the translation, you can review and edit the script before generating the final dubbed audio. This gives you full control over the accuracy and tone of the translation.

Question 7

What languages does DubSync support?

Accepted Answer

DubSync supports over 30 languages including Spanish, French, German, Japanese, Korean, Chinese, Hindi, Arabic, Portuguese, Italian, Turkish, Indonesian, and many more.

Question 8

Can DubSync handle multiple speakers in one video?

Accepted Answer

Yes. DubSync automatically detects and separates multiple speakers, cloning each voice individually. This is ideal for interviews, panel discussions, and multi-speaker presentations.

Question 9

How much does AI video dubbing cost?

Accepted Answer

DubSync offers plans starting from free (5 min/month) to Enterprise ($199/month for unlimited dubbing). The Starter plan at $29/month includes 60 minutes, and the Pro plan at $79/month includes 300 minutes with 4K output and API access.

Question 10

Is DubSync better than traditional dubbing?

Accepted Answer

AI dubbing with DubSync is significantly faster and more affordable than traditional dubbing. A 10-minute video takes minutes instead of days, and costs a fraction of hiring voice actors. While professional studios still excel for theatrical releases, DubSync delivers studio-quality results for digital content, marketing, e-learning, and social media.
