OmniHuman2
OmniHuman 2.0 vs Runway comes down to the job: OmniHuman is a specific image-and-audio-to-character-video model, while Runway is a broader creative workspace with multiple video tools. If your deliverable is a speaking portrait timed to a finished voice track, compare the OmniHuman model with the specific Runway tool you plan to use, not with Runway’s whole subscription.
What you’re actually comparing
BytePlus describes OmniHuman 2.0 as taking a single image and audio, with an optional text prompt, to make an expressive character video. The audio comes first. No script-to-video shortcut here. A useful reference for that job is a chest-up portrait with an unobstructed mouth and enough room in the frame for the gesture you want. The portrait advice is a production choice, not a published input requirement. Our photo-to-talking-video guide walks through preparing that source image.
Runway describes its product as a creative workspace for generating video and images, with audio tools too. Its product page includes character performance among its tools, but the workspace itself is not one model with one input recipe. That’s the trap in a quick comparison: a plan that can make video doesn’t establish that every model on the plan will take your portrait plus a finished voiceover and move the mouth on cue. Check the selected Runway tool’s current input screen before committing a production schedule.
If you’re making a thirty-second spokesperson clip, prepare a voice recording first. If you’re building a cut with generated b-roll and multiple edits, look at the editing workflow instead. Different shopping lists. Different invoices.
| Production question | OmniHuman 2.0 | Runway workspace |
|---|---|---|
| Starting material | BytePlus lists one image plus audio; text prompt optional | Runway lists several video, image and audio tools; inputs depend on the selected tool |
| Character movement | BytePlus describes speech-aware expression, gesture and camera control through prompts | Runway lists character performance and editing among its creative tools; check the selected model’s controls |
| Published output detail | BytePlus lists native 720p; its film-grade tier lists 30–300 seconds | No single workspace-wide duration or resolution applies to every Runway tool |
| Billing unit | BytePlus quotes per generated second for two different tiers | Runway quotes a subscription with credits; usage varies by model |
| Best starting question | “Can I animate this photo to this finished track?” | “Which tool covers all the shots and edits in this project?” |
That distinction matters. The table isn’t a head-to-head quality test. It separates product scope from the one deliverable you’re paying to make. No render test was performed for this article, so claims that either service has better mouth motion would be a guess.
The money changes with the shot
BytePlus lists $0.07 per second for OmniHuman’s film-grade tier, the one it associates with camera and body movement plus multi-person scenes. It lists $0.12 per second for its avatar tier, described with a focus on lip sync. For a 60-second deliverable, the arithmetic is 60 s × $0.07 = $4.20 on film-grade, or 60 s × $0.12 = $7.20 on avatar. Read the OmniHuman pricing breakdown before turning either figure into a monthly budget.
Watch the minimum. It changes the bill. BytePlus says the film-grade tier produces 30- to 300-second videos. If you need a ten-second social cut, don’t treat ten times seven cents as a verified checkout price for that tier. The product page does not spell out the avatar tier’s corresponding duration bounds. Confirm the tier and billable length in the current ordering flow before ordering short clips, and allow for paid retakes in your own estimate. A changed face, a bad pause or a line that runs long can force another generation; how often that happens isn’t documented as a rate.
Runway’s pricing page lists a Free plan with 125 one-time credits and a Standard plan with 625 monthly credits, priced at $15 per month when billed monthly or $12 per month when billed annually. Those are plan prices and credit allowances, not a price per second for a talking portrait. Runway says usage changes with the model and length of the shot; resolution can change it too. Don’t divide the subscription fee by an arbitrary number of seconds and call it an avatar rate. Check the displayed credit charge for your chosen character tool. Multiply it across the shots you actually need.
I would budget the voiceover first and buy generations second. Cutting an unnecessary pause in the audio before generation is cheaper than discovering it after you’ve paid for a full take. That isn’t a claim about either engine’s speed; it’s just sensible edit order.
The control difference on set
BytePlus says OmniHuman 2.0 uses optional text prompts for a specific action or a camera move; prompts can also add objects absent from the source image. That sounds tempting, but a prompt cannot show the viewer a hand that the reference photo has cropped at the shoulder with the same certainty as a real shot. If you want a visible hand gesture, start with a wider photo and describe a single beat: “On the word today, lift the right hand slightly, then rest it.” It is a prompt example. No guarantee.
For a voice-led piece, I’d create a clean thirty-second section with one speaker and a quiet ending. Keep room after the final word so the edit doesn’t cut a mouth mid-syllable. BytePlus lists multi-person scenes on the film-grade tier, but a two-person scene introduces more ways for the viewer to lose track of who is speaking. Test one-speaker framing before committing a whole dialogue script. The lip-sync guide has more on preparing audio and checking mouth movement without claiming a universal fix.
Runway may be the better workspace if the speaking shot is just one ingredient in a larger edit. Its product page describes footage editing and multiple generation tools alongside character performance. Keep your source audio separate from the final export so you can change timing in your editor, whichever generation route you choose. A generated performance is a shot. The edit is still your job.
A fair trial before buying volume
Give both workflows the same creative brief: one cleared fictional portrait, one finished voice track and one requested gesture. Write down your acceptance criteria first: mouth visibly matches the words, the face stays consistent across the clip, no extra person appears, the frame leaves space for captions and the ending has room for a clean cut. You can inspect those things yourself without pretending a published benchmark exists.
For OmniHuman, check BytePlus’s tier description and the price. Confirm the minimum duration before submitting. You can make a video from the OmniHuman2.net overview and consult the step-by-step use guide for the preparation sequence; this site is an independent guide, not the model vendor. For Runway, pick the exact character-performance tool in its workspace, confirm that it accepts the materials you’re holding, and record the displayed credit charge before generating. If it asks for a driving performance you don’t have, that input difference belongs in your decision, not in a vague argument about which company is “better.”
Don’t put client material into either service until you’ve checked the current terms for that job. The BytePlus product page doesn’t document regional availability or commercial-use terms for OmniHuman 2.0; a price listing alone isn’t a rights grant. Start with an image and voice you control, and keep written consent for any identifiable subject before you upload their likeness.
