How FlexTV Scaled Multilingual Content Production with All Voice Lab banner image

FlexTV, a fast-growing global short drama platform under Mega Matrix Inc. (NYSE American: MPU), needed a better way to localize its content across markets. Traditional subtitle editing and translation tools were time-consuming, error-prone, and expensive — making it hard to scale quickly. In March 2025, The FlexTV team integrated All Voice Lab’s suite of AI-powered tools into their post-production workflow. Specifically, they began using All Voice Lab for subtitle extraction, subtitle removal, and AI-powered translation. The result? A dramatic improvement in both localization speed and production efficiency, while keeping costs under control.

“All Voice Lab helped us scale from localizing 10 episodes a day to 100 — all handled by one person. We also cut our average per-episode cost by over 80%. Today, we’re producing localized versions of mini dramas in 12+ languages at scale.”FlexTV Content Operations Team

The Challenge

FlexTV’s traditional subtitle workflow involved a combination of manual transcription, translation services, and time-consuming editing to clean up visuals post-captioning. When localizing to multiple markets, this process became a bottleneck.

For example, removing hardcoded Chinese subtitles without affecting background visuals used to require frame-by-frame editing. Localizing the content for non-Chinese audiences also involved additional tools and resources, pushing the cost per short drama to over $500.

The Solution

By integrating All Voice Lab, FlexTV now automates:

1. Accurate subtitle extraction from existing episodes, including language pairs with low-resource support like Thai, Turkish, and Portuguese

2. Visual cleanup with AI-powered subtitle removal

3. Multilingual subtitle generation

All Voice Lab’s AI handles these tasks in minutes, freeing up FlexTV’s Content Operations Team to focus on creative review rather than cleanup.

Real Results

• 10x Boost in Production Speed

From 10 to 100 localized and published episodes per person, per day

• 82% Cost Reduction

The cost per production dropped from over $500 to under $50

• 7x Faster Translation Efficiency

Compared to traditional AI tools

• Expanded Global Reach

Seamless localization into 12+ languages, including English, French, German, Japanese, Korean, etc.

“All Voice Lab’s tools allow us to bring stories to more people, faster. It’s been a key enabler of our international expansion.”FlexTV Operations Lead

What Makes All Voice Lab Stand Out

Many off-the-shelf tools fail when handling mixed-language content or hardcoded subtitle layers. All Voice Lab’s deep learning-based subtitle removal is not only more accurate, but it also preserves scene integrity—essential for platforms like FlexTV where visual fidelity matters.

Thanks to native support for multi-language content, errors due to script-switching are significantly reduced, improving viewer experience.

A Scalable Future

With these proven gains, FlexTV has fully integrated All Voice Lab into its global production workflows. As a result, the company is scaling short drama content across Southeast Asia, Latin America, and Western markets— with accurate subtitle extraction and clean visuals tailored for each region.
