FASTER-WHISPER + GEMINI 2.5 + WAV2LIP-GAN LIP-SYNC|15 Languages (Hinglish, Traditional Chinese, Cantonese) • Unlimited BYOK Mode • MCP Server

Localize any video into 15 languages with frame-locked neural voices & AI lip-sync.

Drop an MP4 or paste a YouTube or TikTok link. GlobalCast isolates background music, adapts syllable-matched translations (including Romanized Hindi/Hinglish, Traditional Chinese & Cantonese), synchronizes speaker lip movements via Wav2Lip-GAN, and masters -14 LUFS video, WAV stems, bilingual captions, and viral social metadata. Includes 10 free cloud credits + Unlimited 0-Credit BYOK Gemini Mode.

Engineered to eliminate vocal overlap and clipped endings.

Most dubbing tools blindly concatenate translated TTS files, causing speakers to talk over each other when languages like Spanish or German use more syllables than English. GlobalCast solves this at the signal chain level.

STAGE 01 // FASTER-WHISPER ASR

4x CTranslate2 + SHA256 Cache

FFmpeg extracts a 16kHz PCM stream and runs CTranslate2 Faster-Whisper with SHA256 audio caching so multi-language batch jobs transcribe only once.

STAGE 02 // GLOSSARY & SEO PACK

Gemini 2.5 Flash Adaptation

Gemini adapts the full script to match each segment's duration, locks your custom brand glossary, and generates localized YouTube/TikTok titles and hashtags.

STAGE 03 // ANTI-OVERLAP FIT

Dynamic atempo + Cursor Lock

Each 24kHz neural segment receives an 80Hz rumble filter and dynamic time-fitting (`1.0x–1.32x atempo`) with a strict monotonic cursor so lines never collide.

STAGE 04 // EBU R128 MASTERING

Vocal Carve & -14 LUFS Master

Original speech frequencies are carved out to preserve music/SFX, audio is normalized to `-14 LUFS`, and MP4, WAV stem, Bilingual SRT, and VTT files are exported.

Technical Specifications & FAQ

How does GlobalCast AI prevent translated sentences from overlapping or cutting off?

Every segment is measured via ffprobe after neural synthesis. If a translated phrase is longer than the original speaker's pause window, our engine applies dynamic FFmpeg atempo time-fitting (up to 1.32x) and enforces a strict monotonic timeline cursor. If the final sentence extends beyond the video tail, tpad frame-cloning extends the final video frame so speech never clips.
