Mandarin	96%	92%

2. Language-specific models — Separate models for English, Spanish, Japanese (vs. Synthesia’s general model)
3. Real-time preview — Adjust lip-sync offset in editor (Synthesia requires re-render)

Deep Dive: Open-Source Tools (HeyGen Only)

In January 2026, HeyGen open-sourced two tools on GitHub:

1. Smart Subtitles

• What it does: Auto-generates subtitles with speaker tracking and word-level highlighting
• Why it matters: Saves $50-200/mo on subtitle services (Rev, Kapwing)
• Self-host: Docker container, runs on CPU

Cost savings example (100 videos/mo):

• Before: $99/mo (Rev.com auto-subtitles)
• After: $0 (self-hosted HeyGen tool)
• Annual savings: $1,188

2. Local Background Removal

• What it does: Removes background from talking-head videos with semantic understanding
• Why it matters: No need for green screen or manual masking
• Self-host: Requires GPU (CUDA) for real-time processing

Cost savings example (100 videos/mo):

• Before: $50/mo (Remove.bg API)
• After: $0 (self-hosted HeyGen tool, one-time GPU cost ~$500)
• Break-even: 10 months
