HeyGen render tests

Every clip rendered so far, with what it cost and what it shows. Transparent clips are on a checkerboard so you can see the cut-out.

Your characters — Sam & Nour

Sam · Avatar IV Hands rise, come together, then open wide. This is what gesture looks like.

$2.31/min4 credits gesturestransparent

Sam · Avatar III Hands stay at his sides the whole time. Only the mouth moves.

Ms. Nour · Avatar III Hands clasped throughout. Some head and torso sway, no hand movement.

Putting them in the room

Not shown, because it does not work yet. The cut-out itself is clean — hair edges, fingers, the gap under an arm all matte correctly. But the room plate has both seats already occupied by the current hosts and a fixed camera scale, so a new person cannot be placed into it without overlapping someone and coming out the wrong size.

What it needs first: the room regenerated with empty seats, and each host rendered at a seated framing rather than standing. Until then any composite I show would be misleading.

The $0.60 tier — a stock studio avatar

Stock studio avatar · Avatar III The $0.60 tier. Hands clasped in her lap, identical across all four frames. Transparent, but no body movement.

$0.60/min2 credits · 5.09s no gesturetransparent

Annelore · studio avatar · Avatar III Highest movement score of any $0.60 render — but framed head-and-shoulders, so there are no hands in frame. The motion is head, shoulders and hair.

Earlier tests — a stock HeyGen avatar

Stock photo avatar · Avatar IV The first proof that a motion prompt produces real gesture.

Stock photo avatar · Avatar III Same avatar, same script, cheaper engine. Hands clasped, motionless.

Rates verified against real charges. Avatar III billed 2 credits for 4.05s and 3 for 6.81s — exactly 20 credits/min rounded up, i.e. $0.99/min. Avatar IV billed 4 credits for 4.44s — 46 credits/min, $2.31/min.

All three tiers now measured. Every one exports a clean transparent cut-out. Only Avatar IV moves — the two cheaper tiers give a static figure whose mouth moves and nothing else. The $0.60 tier also means HeyGen’s faces rather than Sam and Nour.
