A single photo can become a video of a talking avatar, complete with natural expressions and lip-syncing.

P-Video-2-Pro-Avatar also supports audio alone or speech from text, up to 3 minutes. It's interesting to create content without needing to re-record it.

The 50% launch discount is valid until November 5.

[Bertrand Charpentier @Bertrand_Charp]

Below 4 bits, the “implementation details” become the method. Representation, calibration data and recovery data decide whether a 2-bit model works at all.

1️⃣ Representation dominates: At ~2 bits, when scalar PTQ falls to chance, vector PTQ can maintain accuracy.

2️⃣ Calibration and recovery data must be chosen jointly: Using recovery data different from calibration performs better.

3️⃣ Recovery is cheap but model-dependent: while vector quantization recovery works well on some models with 1.4–30x less compute than any QAT, no recovery worked best on some models.

First test of P-Video-2-Pro-Reference, using my character sheet as a visual reference for a 15-second, 16:9 fashion clip.

Fun to see a character design move from a static reference into video. Looking forward to trying more reference combinations. @PrunaAI
