Benchmark 1: Generate an Avatar Video from a Script
Task: Create a 90-second explainer video in German from a given script.
Synthesia
Synthesia offers over 230 pre-built avatars with professional looks (business, casual, diverse ethnicities). The interface is clearly structured: choose a template, enter the script, select an avatar, start the render.
The result after ~4 minutes of render time: a cleanly produced video with consistent lip synchronization. The avatars look professional and move naturally. The visual style is rather conservative and business-oriented — ideal for training videos, less so for creative marketing content.
Rating: 8.5/10 — High quality consistency, professional look.
HeyGen
HeyGen offers 100+ avatars plus the ability to create custom avatars from short video clips (InstantAvatar in 2 minutes). The interface is more intuitive than Synthesia's for new users.
The result after ~3 minutes: high-quality lip synchronization, more lively avatar movements than Synthesia. HeyGen produces movement profiles that feel slightly more natural.
Rating: 8.8/10 — More natural movements, faster rendering.
Benchmark winner: HeyGen (by a narrow margin)
Benchmark 2: Lip Sync Quality in German
German presents a particular challenge for AI avatars: long compound words, strong emphasis, and specific mouth shapes.
Synthesia in German
Synthesia supports over 140 languages and has made deep investments in language quality. In German: lip synchronization is good, with minimal blurring on long compound words. The German voices sound natural, especially in a business context.
Rating: 8.2/10 — Solid, minimal artifacts with compound words.
HeyGen in German
HeyGen now supports 175+ languages. German quality: very similar to Synthesia, with slight advantages for more emotive speech. German voices in HeyGen feel slightly more alive for marketing video contexts.
Rating: 8.4/10 — Marginally more natural for marketing contexts.
Benchmark winner: HeyGen (very narrow margin)
Benchmark 3: InstantAvatar — Creating Your Own Avatar
Task: Create a usable personalized avatar from a 2-minute video.
Synthesia Custom Avatar
Synthesia requires a separate recording process with specific requirements for lighting, camera, and clothing to create high-quality custom avatars (Photo Avatar or Video Avatar). The quality is excellent — but the process takes longer and is more demanding.
Rating: 8.5/10 — Best quality, more involved process.
HeyGen InstantAvatar
HeyGen's InstantAvatar creates a ready-to-use avatar from a short video clip (2+ minutes) in ~20 minutes. Quality: very good for quick applications. Well suited for live streams and personalization campaigns.
HeyGen also offers Photo Avatar — a talking avatar generated from a single photo. Ideal for email videos and simple explainer videos.
Rating: 9.0/10 — Fast process, sufficiently high quality.
Benchmark winner: HeyGen (clear advantage in speed)
Benchmark 4: Video Translation
Task: Automatically translate an existing German explainer video into English — with adapted lip synchronization.
Synthesia Video Translate
Synthesia offers video translation in 140+ languages. In testing: a 2-minute German video was correctly translated into English. Lip sync quality: good, but with minor artifacts at faster speaking speeds.
Rating: 8.0/10
HeyGen Video Translation Hub
The Video Translation Hub is HeyGen's flagship feature. Translate existing videos into 175+ languages — with adapted lip synchronization matching the original. The result is impressive: the original speaker's face moves their lips in sync with the new language.
Use case: companies with videos in one language who want to localize them for global markets. Create one video, translate it into 10 languages — without any new recordings.
Rating: 9.2/10 — Clearly market-leading.
Benchmark winner: HeyGen (by a significant margin)
Benchmark 5: Value for Money at the Lowest Tier
Question: What do you get for ~$29/month?
Synthesia Starter ($29/mo)
- 3 videos per month
- Max. 30 minutes total video length
- 70+ standard avatars
- 50+ template designs
- No API access
Verdict: 3 videos/month is very limited for the price. Anyone producing videos regularly quickly ends up on the Standard plan ($89/mo).
Rating: 6.5/10 — Poor value for money at the entry tier.
HeyGen Creator ($29/mo)
- 15 minutes of video/month
- All standard avatars
- Video Translation (limited)
- API access (limited)
- 1 InstantAvatar included
Verdict: 15 minutes/month equates to approximately 8–10 short videos. Significantly more value than Synthesia's 3 videos.
Rating: 8.0/10 — Significantly better value for money.
Benchmark winner: HeyGen (clear advantage)
