- Front-facing medium shot of a cheerful woman in her 30s with curly auburn hair tied back, wearing a linen apron over a white shirt, standing behind a wooden kitchen counter with tomatoes, basil, and a cutting board arranged in front of her, bright rustic kitchen softly blurred behind, warm natural window light, photorealistic, 4:3.
- Voice script
- Welcome back to the Sunday table. Today we're keeping it simple — five ingredients, fifteen minutes, one pan. Start with your tomatoes: cut them in half, and don't you dare throw away the juice, that's flavor. Basil goes in last, always last, or it turns bitter. And here's the part everyone rushes — let the pan get properly hot before anything touches it. Give it two full minutes. Your patience gets rewarded, I promise.
- Avatar prompt
- A warm cooking-show host stands behind a wooden kitchen counter with fresh ingredients laid out. She speaks to the camera, gestures naturally with her hands to point at the ingredients, occasionally leans forward for emphasis, head and shoulders framed in a steady medium shot, soft natural kitchen lighting, realistic body movement

Workflow
From portrait and audio to talking avatar
Avatar quality starts with the source assets. Finish the portrait and voice track before spending credits on generation.
-
01
Choose a model
Pick portrait animation for a specific person or character, or audio-first lip sync when a supplied image is optional.
-
02
Prepare the image
Use a sharp, well-lit portrait with a visible face and simple framing. LTX can use its default portrait instead.
-
03
Add clean audio
Upload the final voice track. Clear speech and minimal background noise produce more reliable mouth movement.
-
04
Generate and review
Check lip sync, identity, expression, and framing, then refine the source assets or motion prompt one variable at a time.
Source checklist
Clear face · even lighting · simple framing · clean single-speaker audio · silence trimmed · final pronunciation checked
Practical details
Frequently asked questions
Which AI avatar model should I use?
P Video Avatar is a strong fit for fast avatar video and 1080p avatars. Omni Human 1.5 is a strong fit for lifelike portraits and facial expression. LTX 2.3 LipSync is a strong fit for audio-first lip sync and optional portrait. Wan 2.2 Avatar is a strong fit for long avatar videos and face and body motion.
What inputs do I need?
P Video Avatar, Omni Human 1.5, and Wan 2.2 Avatar require a portrait image and audio track. LTX 2.3 LipSync requires audio and can optionally use your portrait image.
What makes a good avatar image?
Use a clear face, even lighting, visible facial features, and an uncluttered composition. Front-facing or slight three-quarter portraits are the most predictable starting point.
What makes good source audio?
Use clean speech with minimal background noise, clipping, or overlapping speakers. Trim silence and finalize pronunciation before generating, because the audio duration controls the video length and cost.
Can I control body movement?
P Video Avatar includes a video prompt for body movement, framing, and atmosphere. LTX and Wan also accept optional prompting for style or presentation.
How long can avatar videos be?
Limits vary by endpoint. LTX 2.3 supports audio from 5 to 20 seconds, while P Video Avatar, Omni Human 1.5, and Wan 2.2 support audio up to 10 minutes.
Can I try the avatar generator for free?
Yes. New RenderFlow AI accounts receive 35 monthly credits on the Free plan, with no credit card required.
How many credits does avatar generation cost?
P Video Avatar: From 13 credits for 5 seconds at 720p. Omni Human 1.5: 16 credits per second of audio. LTX 2.3 LipSync: From 10 credits for 5 seconds at 480p. Wan 2.2 Avatar: From 15 credits for 5 seconds at 480p.
