Hedra vs HeyGen for Talking-Character Ads: Build the Character or Cast From 1,100+ Presenters

A character that performs, or a presenter who explains

A pet-food brand has two briefs on the same Monday. The first is a 20-second TikTok hook in which the brand's cartoon beagle complains about its bowl. The second is a 45-second retargeting explainer, delivered by someone who looks like the founder. Both need a face that talks. Nobody wants to book a shoot.

Hedra and HeyGen will both make a still image speak, and at first glance they look priced for the same buyer. As of September 17, 2026, Hedra's Creator plan is $30 a month for 5,400 credits, and HeyGen's Creator plan is $29 a month for 600 credits. Those two lines invite a comparison they cannot carry, because the products underneath start from different places. Hedra is built around a character you design and a choice of models to perform it. HeyGen is built around a presenter: one of its 1,100+ stock avatars, a photo avatar, or a digital twin of a real person.

One disclosure before the comparison. Novoads, which publishes this post, also sells AI talking-actor video for ads, so we compete with both products. Every Hedra and HeyGen fact below comes from the vendor's own pages, fetched on September 17, 2026, and where Novoads fits is kept to its own section near the end.

The short version for ad teams

If you read one section, read this one. The rest of the post shows the work behind each line.

Choose Hedra when

• The face in the ad is a character: a mascot, an animal, an illustrated or clay figure, or a person you generated rather than filmed.
• You want to pick the performance model per clip, from Hedra's own Character 3 and Hedra Avatar to third-party audio-driven models on the same account.
• You are building a pipeline and want per-second API prices you can read on a public model page.

Choose HeyGen when

• The face is a presenter: a stock avatar from a large library, or a digital twin of a founder or spokesperson.
• The same ad has to ship in many languages, since HeyGen's paid plans list 175+ languages and dialects.
• You want a published credit meter inside the app, with unused monthly credits that roll over for one more cycle.

Two products built around different starting points

Both vendors now sell a talking video made from a still image. What differs is what each one puts in front of you first, and that shapes how much work a given ad takes.

Hedra: design the character, then choose who performs it

Hedra does not present itself as an avatar app. It calls itself "a visual intelligence and inference company", and its lip-sync page says plainly that lip sync is a capability of the selected model, not Hedra's product category. Its talking-avatar page names the performance models behind that: "Hedra Avatar and Hedra Character 3 are ours; Omnihuman, Kling AI Avatar and VEED Fabric run on the same engine and the same key."

The workflow starts from the character, not the script. Hedra's character generator page describes the path end to end: generate a character with image models, save it as a reusable Element so the same face returns in later prompts, then "pair the character image with a script and a voice". The character does not have to be human. The gallery on Hedra's Character 3 page includes a talking bear roofing contractor, a fox scientist and a claymation musician, and its talking-photo page says an illustration or cartoon becomes an animated character and "a brand mascot becomes a spokesperson."

HeyGen: pick or clone a presenter, then write the script

HeyGen's front door is the presenter. Its avatar page offers "1,100+ AI presenters ready to use", a photo avatar made from one front-facing headshot, and a custom avatar built from a short recording of a real person, which requires that person's verified consent. Its UGC ad flow follows the same order: "Write your script, pick a creator-style presenter, and generate polished UGC ads."

HeyGen builds its own avatar engines and sells them by generation. Avatar IV turns a single photo into a talking video with hand gestures. Avatar V, which HeyGen calls its most advanced AI avatar model, learns a person from a 15-second webcam recording and holds that identity across scenes, outfits and camera angles. The investment points one way: making a specific person look like themselves in every video.

Where the two overlap more than the marketing suggests

The line between character and presenter is not a wall. Three facts from the vendors' own pages blur it:

1. HeyGen animates characters too. Its Avatar IV page says the model "supports human, anime, and animal avatars in both portrait and full-body formats."
2. Hedra builds presenters too. Its UGC ad workflow tells you to "create the presenter, product shots, voice, and supporting visuals in the same Space."
3. Hedra serves a HeyGen model. Hedra's model catalog lists HeyGen Photo Avatar 4 at 10 cents per second, next to Hedra's own avatar models.

So the honest distinction is not what either tool can technically render. It is what each product is organized around.

How each one makes a face perform

A talking-character ad lives or dies on the performance: lip sync, expression, and whether the gestures fit the line. The two vendors expose that layer in different ways.

Hedra's audio-driven models

Hedra Character 3 takes an image, a text prompt and a required audio track and turns them into speech-driven video. Its model page lists seven aspect ratios including 9:16, output at 540p, 720p or 1080p, and a maximum duration of 10 minutes. Hedra says Character 3 was released in March 2025.

The same page is candid about a quirk. If the character makes overly dramatic hand gestures, Hedra's advice is to "use your text prompt to explicitly restrain their movement." That matters for ads: a character that over-acts a supplement claim reads as parody, so budget a prompt pass for restraint. For how likeness, voice and lip sync fit together inside these tools, see our explainer on how an AI avatar video generator works.

Because several models sit on one account, the practical move in Hedra is to render the same still and audio on two or three of them and keep the best take. Hedra frames the trade itself: Hedra Avatar "runs up to ten minutes from a single audio file", while "the clip-oriented models are built for the short vertical cuts that social rewards."

HeyGen's avatar generations

HeyGen's help centre prices three generations of its own engine in credits: Avatar III, Avatar IV and Avatar V. Avatar IV starts from a photo, and its page says it can work from "tilted heads, profiles, and angled poses", not only front-facing shots. For more movement, HeyGen sells Custom Expressive Motion, which lets you prompt the avatar's gestures on Avatar IV for an extra 40 credits per minute.

Avatar V is the consistency play. HeyGen's own comparison table rates Avatar IV's long-form consistency as degrading over time and Avatar V's as stable beyond 30 minutes. That gap matters little for a 20-second hook and a lot for a founder explainer series, where one face has to hold across dozens of videos. If you are starting from a single headshot rather than footage, our guide to making an AI avatar from a photo covers the input side.

Voices and languages

Both let you type a script or bring your own audio. The difference is emphasis:

• Hedra offers voices from ElevenLabs and MiniMax, voice cloning and uploaded recordings, and its lip-sync page puts the language rule simply: "Lip sync follows the audio, so any language the voice speaks, the character speaks."
• HeyGen lists 175+ languages and dialects and voice cloning on its Creator plan, plus a video translator that re-voices an existing video with lip sync, at 6 credits per minute in speed mode.

For an ad that runs in one market, this is a wash. For a winning ad you want live in eight markets next week, HeyGen's translation workflow is the more finished tool. Our HeyGen vs Synthesia comparison prices that workflow against Synthesia's lip-synced dubbing.

What the plans cost, as of September 17, 2026

Both vendors publish their plan ladders without a signup. Neither pricing page carries a date, so read these as the prices shown on the day we fetched them.

	Hedra	HeyGen
Entry paid plan	Basic, $15 a month	Creator, $29 a month
Credits on that plan	1,500 a month	600 a month
Next plan up	Creator, $30, 5,400 credits	Pro from $49, 1,000 credits
Top individual tier	Professional, $75, 14,400 credits	Pro tiers up to $4,300
Unused monthly credits	Do not carry over	Roll over one cycle
Per-model credit rates	Shown in the app	Published in help centre
API billing	Per second of output	Per minute, by seconds

Hedra's ladder

Hedra's pricing page lists Basic at $15 a month with 1,500 credits, Creator at $30 with 5,400 and Professional at $75 with 14,400, each marked "Billed monthly". A Teams plan sits at the same $75 and 14,400 credits, and Enterprise is custom. Every paid plan lists commercial use. What changes as you climb, on the page, is mostly credits and speed, from "Slower generations" on Basic to "Fastest generation" on Professional.

Hedra also invites you to "Start free, upgrade anytime", but its character generator FAQ says outputs at that level "may include a Hedra watermark and are for non-commercial use", so a test render is not an ad you can run. Monthly subscription credits do not carry over between billing cycles; credits bought in packs do not expire.

HeyGen's ladder

HeyGen's Free plan is $0 and lists 3 videos a month of up to 1 minute. Creator is $29 a month, or $24 a month if you pay annually, with 600 credits, 1080p export and watermark removal. Pro starts at $49 for 1,000 credits and scales in tiers "from 1,000 credits/mo at $49 to 100,000 credits/mo at $4,300." Business is $149 a month plus $20 per extra seat.

Two credit rules shape a month of ad work. Unused monthly credits roll over for one additional billing cycle. And Creator cannot buy one-time credit packs, so running out mid-month means upgrading to Pro. For how HeyGen's meter compares with a per-ad meter, see our HeyGen vs Creatify breakdown.

Why 5,400 credits and 600 credits do not compare

A credit is a unit each vendor defines for itself, so a raw count says nothing until you know the meter behind it.

• HeyGen publishes its meter. Avatar IV costs 16 credits per minute with a photo look and 31 with a video look; Avatar V costs 48 credits per minute.
• Hedra keeps its meter in the product. Its documentation says exact credit prices, duration limits and resolutions are intentionally not duplicated there, and tells you to check the live model selector before generating.

The public number you can hold Hedra to is its API rate per second. That is where the worked example starts.

A worked example: 20 thirty-second character spots

Take one brief: 20 talking-character ads, 30 seconds each, one take per ad. That is 600 seconds, or 10 minutes of generated performance. Here is what the published meters say it costs.

Through the APIs, where both sides publish a rate

The API equation: cost = seconds generated × rate per second, before any retakes.

• Hedra Character 3 on Hedra's API: $15.00 at 540p (2.5 cents a second), $30.00 at 720p (5 cents) and $37.50 at 1080p (6.25 cents). Hedra Avatar lists the same three rates.
• HeyGen Photo Avatar 4 through Hedra's API: $60.00, at 10 cents a second at every listed resolution.
• HeyGen's own API: $23.10 at the Avatar IV photo avatar rate of $2.31 a minute, $48.30 for an Avatar IV digital twin at $4.83, and $72.00 for an Avatar V digital twin at $7.20. HeyGen says API video is charged by actual seconds generated, and you can buy API credits without a Creator, Pro or Business plan (creating a twin through the API is Enterprise-only).

Inside HeyGen's Creator plan

In the app, the same 10 minutes cost 160 credits on Avatar IV with a photo look, 310 with a video look, and 480 on Avatar V. All three fit inside Creator's 600 monthly credits. Add Custom Expressive Motion to the Avatar IV photo-look version and it becomes 560 credits, which still fits, barely.

Inside Hedra's plans

Here the arithmetic stops, on purpose. Hedra's credit rate for Character 3 shows up in the model selector, not on a public page, so the 5,400 credits on Creator cannot be turned into minutes from outside an account. The clean way to find out is one short render: Hedra's billing history records each generation as "a credit debit, refund, or related generation event", so a single 10-second test tells you the rate for the model and resolution you will actually use.

What the arithmetic leaves out

Retakes. Expressive performance is where they pile up, and Hedra's own advice on reining in dramatic gestures hints that the first take is not always the keeper. If one take in three makes the cut, multiply every figure by three:

• $90.00 at 720p on Hedra's Character 3 API.
• $69.30 on HeyGen's Avatar IV photo avatar API.
• 480 credits on HeyGen Creator with a photo look, still inside the plan.
• 1,440 credits on Avatar V, more than Creator's 600 and more than Pro's entry tier of 1,000.

How many variants a real test needs is its own question, which our guide to how many ad creatives you need works through.

Which one fits your ad program

The worked example shows cost. Fit comes down to what the creative needs from the face.

Where Hedra is the better-shaped tool

• Mascot and character-led ads. When the brand's spokesperson is a cartoon, an animal or a figure you designed, Hedra is organized around exactly that object: generate it, save it as an Element, give it a voice.
• Mixed formats in one place. In a customer story Hedra published on July 29, 2026, Hedra says the agency Finso runs "cartoon and VSL-style explainer animations" beside talking-head creatives, "relying primarily on Kling and Veo 3.1 models" inside Hedra. It is a vendor-published testimonial, so read it as a workflow example, not a benchmark.
• Model shopping at the performance layer. If one audio-driven model over-acts and another under-acts, you swap models without changing tools.

Where HeyGen is the better-shaped tool

• A real person on camera, at scale. Founder explainers, sales videos and spokesperson series benefit most from Avatar V's identity consistency.
• Localizing a winner. 175+ languages and dialects, plus lip-synced translation of a video you already have.
• Budget predictability. A public per-minute meter, a Creator plan that covers 10 minutes of Avatar IV with room to spare, and monthly credits that stay usable for a second cycle.

How HeyGen stacks up against tools built for handheld UGC is covered in the best HeyGen alternatives for UGC ads, and against a multi-model generation studio in our HeyGen vs Higgsfield comparison.

Test both on the same inputs

A fair test holds everything constant except the tool:

1. Use one still image and one audio file for both, so the voice is not the variable.
2. Render a 10-second hook and a 30-second full spot on each.
3. Judge lip sync on hard consonants, gesture restraint during the claim, and whether the face holds its identity to the last frame.
4. Run the survivors as a small paid test and read the result with a proper method, as in our guide to ad creative testing.

Whichever tool wins, check the platform rules on synthetic people before launch. Our summary of the Meta, Google and TikTok rules on labeling AI-generated ads is the place to start.

Where Novoads fits, with a disclosure

Novoads is an AI UGC video-ad generator, so it competes with both products in this post. You upload a product image or write a script, pick an AI actor, and get an ad-ready video. It offers one talking-actor model, where Hedra lets you choose among several, and it markets 100+ AI actors, a much smaller library than HeyGen's 1,100+. Those are real concessions.

The pricing is published and different in shape. A Novoads talking-actor video costs 10 credits per started minute, so a 30-second spot costs the same 10 credits as a 60-second one. Short clips are where that block is least efficient, and a per-second meter like Hedra's API suits them better. For product shots and B-roll, video clips in Novoads run from about a dollar for a five-second Seedance 2.0 Mini clip to about $8 for an eight-second Seedance 2.5 clip, and about $26 for a full 30-second Seedance 2.5 take. Novoads starts at $49/month (Starter, 50 credits per month), and all plans are published on /pricing.

If your ad starts from a product photo and a script, Novoads is worth a test beside these two. If it is a talking mascot, Hedra is the better-shaped tool; if it is a founder in forty languages, HeyGen is. Our separate head-to-head, Novoads vs HeyGen, makes that case in full.

Pick the brief first, then the face

The pet-food brand from the opening does not have to choose one tool for both briefs. The cartoon beagle belongs where characters are the organizing object, and the founder explainer belongs where presenters are. Credits, cents and minutes only become comparable once you know which kind of face the ad needs. A talking mascot and a talking founder are different ads, and the right tool is the one built around the one you are making.
