Animate stills with HeyGen Avatar 4 — image-to-video that respects identity

Upload the first frame, describe the motion, get a continuous shot.

Talking-head video from one portrait. Type a script and voice, or upload audio. This is the image-to-video lane for HeyGen Avatar 4. Upload a single still — a portrait, a product shot, a key frame — and write a motion prompt describing camera, gesture, or environmental change. HeyGen Avatar 4 treats the uploaded image as the opening frame and continues from there, preserving the subject's identity, wardrobe, and proportions across the clip. Strengths: talking-head video, text-to-speech avatars, lip sync from audio. Use this for editorial portraits, product turntables, music video pickups, or simply punching life into stock stills.

How to animate stills with HeyGen Avatar 4

Five steps to consistent, identity-locked motion.

1. Upload a clean reference image — the model uses this as the opening frame, so blur, watermarks, and weird crops all carry over.
2. Write a motion prompt that describes the camera move and any new actions. Keep it short and specific.
3. Pick duration and resolution from the options HeyGen Avatar 4 surfaces.
4. Submit; the orchestrator polls the async job and saves the result in your Tool Runs when it's ready.
5. Re-run with the same reference and a different motion prompt to sample alternative cuts.

What HeyGen Avatar 4 animates well

Strengths called out on HeyGen's own model card.

Talking-Head Video

Why people pick this model

HeyGen Avatar 4 is consistently picked for talking-head video — it shows up first on HeyGen's own published model card and again in real-world side-by-side tests.

Text-to-Speech Avatars

Where it edges the competition

Text-to-Speech Avatars is the named differentiator on HeyGen Avatar 4 versus other HeyGen releases — useful when this is the axis that actually matters for your output.

Lip Sync from Audio

A strength on the model card

If your job hinges on lip sync from audio, HeyGen Avatar 4 is the lane to choose; the model team optimized for this trade-off explicitly.

Multiple Resolutions

What it is consistently good at

Multiple Resolutions is the reason HeyGen Avatar 4 gets the dedicated landing page instead of being buried behind the multi-model picker.

Portraits

Subtle living portraits

Animate editorial portraits with breath, eye flicks, and micro-smile motion — without restyling the face.

Product turntables

From single hero shot

Generate a slow product orbit from one studio still — great for landing pages.

Where HeyGen Avatar 4 fits in real workflows

Concrete use-cases that justify a dedicated landing page.

• Bring editorial portraits to subtle, living life
• Turn a single product still into a hero turntable shot
• Add motion to concept art for pitch decks
• Generate cutaways tied to an exact opening frame
• Match new motion to a specific look from a still shoot

Why a dedicated HeyGen Avatar 4 workspace

And why pinning the model matters.

Image-to-video is unforgiving: any drift between the uploaded frame and the rendered clip reads as "AI weirdness". HeyGen Avatar 4 is tuned to preserve identity, wardrobe, and proportion across frames; strengths: talking-head video, text-to-speech avatars, lip sync from audio, multiple resolutions. The form is intentionally small — one reference image, one motion prompt, the knobs HeyGen Avatar 4 exposes — so you spend brain cycles on the shot, not the configuration.

Pro tips for HeyGen Avatar 4

Small adjustments that meaningfully improve output quality.

1. Upload the cleanest reference you have — HeyGen Avatar 4 treats the upload as the opening frame, so artifacts carry across the clip.
2. Keep motion prompts short and specific. "Slow dolly-in, subject turns to camera" beats "make it feel alive".
3. For portraits, use the smallest motion that sells the shot — subtle blink and breath beats over-animated head turns.
4. When the subject's identity drifts mid-clip, lower the motion intensity (where HeyGen Avatar 4 exposes that) or shorten duration.
5. Match the motion prompt to the lighting in the reference — implied wind in a windless still reads as fake.
6. Generate multiple variants; image-to-video has higher variance than text-to-video, and the second attempt often wins.

HeyGen Avatar 4 on Gab AI — frequently asked questions

What is HeyGen Avatar 4?

HeyGen Avatar 4 is an AI image-to-video model built by HeyGen. HeyGen Avatar 4 — talking-head video from one portrait. Type a script and voice, or upload audio. On Gab AI it's available as a standalone, pinned tool — runs through the same orchestrator, credits, and file pipeline as chat.

Is this tool free to use?

Anyone with a Gab AI account can run HeyGen Avatar 4. Each run deducts the model's per-request credit cost from your balance — there's no surprise per-month fee.

What does it cost per run with HeyGen Avatar 4?

Credit cost is set on the underlying HeyGen Avatar 4 model, not on this tool. The form recalculates and displays the exact cost as you change duration and resolution, so you see the bill before you submit — never after.

How long is the generated clip?

Duration is controlled by the model's own parameter set. HeyGen Avatar 4 exposes the durations it actually supports in the form, with credit cost shown per option so you can budget the run.

Will HeyGen Avatar 4 watermark videos?

HeyGen Avatar 4 does not embed visible watermarks by default in this pipeline. Vendor-side invisible content-credentials may still be present — that's a model behaviour, not a tool one.

Why a separate tool for every model?

Because every model is different and the multi-model picker quietly hides those differences. Pinning HeyGen Avatar 4 to its own tool gives you predictable cost, consistent style, and a fair lane for comparing one model's output against another's without confusing the cause of the difference.

Can I switch to a different model from here?

Yes — every model gets the same kind of landing page. Use the catalog at /tools to browse all model-playground tools, or pick a different one from the related tools section below.

Where do my runs go?

Every run lands in your Tool Runs (under My Library). You can revisit, download, fork, or continue any run in chat for follow-up work.
