Pro tips for each
HeyGen
AI Avatar · Video Dubbing

Expensive on default settings; the right settings matter most here

Create an Instant Avatar from just 2 minutes of video — stand in front of a plain wall, record yourself talking, and HeyGen builds a forever-usable avatar.
Use Video Translation to dub existing videos into other languages with your cloned voice; have a native speaker check each language before publishing.
Script your avatar videos for teleprompter reading — HeyGen avatars perform best on clear, well-paced narration; avoid long pauses in scripts.

Synthesia is best for corporate training and L&D videos — its avatars are more professional and business-appropriate than HeyGen's.
Use the Brand Kit to lock colors, fonts, and logos — all videos auto-apply your brand, saving 20 minutes of formatting per video.
Break long training into 3–5 minute micro-videos.
