# Heygen 路 Avatar4 路 Image to Video API > Menganimasikan satu foto wajah menjadi avatar berbicara, dengan gaya bicara stabil atau ekspresif Mengubah satu gambar yang berisi wajah jelas menjadi video avatar yang berbicara. Berikan `prompt` berisi teks yang akan diucapkan beserta nama `voice`, atau sediakan `audio_url` yang mengesampingkan keduanya. `talking_style` beralih antara stable (gerakan minimal) dan expressive. Anda juga dapat menetapkan ekspresi, latar belakang, takarir opsional, serta resolusi dari 360p hingga 1080p. - Model id: `heygen/avatar4/image-to-video` - Made by: HeyGen - Category: Lipsync & Avatars - Output: video - Price per second of your input audio: $0.10 / second of input audio (cheapest run $0.10 (100 API credits)) - Run: `POST https://api.doitong.ru/v1/run/heygen/avatar4/image-to-video` - Quote: `POST https://api.doitong.ru/v1/quote/heygen/avatar4/image-to-video` - Docs page: https://doitong.com/id/developers/models/heygen/avatar4/image-to-video ## Pricing Price: **$0.10 / second of input audio**. Price per second of your input audio: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges. The full example input below costs $1.00 = 1000 API credits (10 s input audio 脳 $0.10). Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.ru/v1/quote/heygen/avatar4/image-to-video` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically. ## Input parameters Send either the canonical name or the native field name (not both). Canonical names are the same across models. | Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description | |---|---|---|---|---|---|---| | `image_url` | `image` | string (image URL) | yes | | | Sumber animasi yang diberikan sebagai URL gambar; pilih gambar dengan wajah yang terlihat jelas. | | `prompt` | | string \| null | no | | | Teks yang akan diucapkan avatar. | | `voice` | | enum (string) \| null | no | | `Warm Pro Narrator`, `Chill Brian`, `Ivy`, `John Doe`, `Monika Sogam`, `Hope `, `Archer `, `Brittney`, `Patrick`, `David Castlemore`, `Michael C`, `Adam Stone `, `Juniper`, `Cassidy `, `Jessica Anne Bogart`, `Arabella`, `Andrew`, `Spuds Oxley `, `Grace Elder`, `Helen`, `Canyon Rivers`, `Derya - Lifelike - Excited 馃ぉ`, `Mellow Marcus`, `Jack Sterling - Broadcaster 馃帣锔廯, `Brenda - UGC - 1.mp4`, `Reid`, `Reagan`, `Terry`, `Jenny`, `Radio Rick`, `Denise`, `Tim in car - Excited 馃ぉ`, `Iskander`, `Thompson`, `Delicate Daisy - Excited 馃ぉ`, `Kingston`, `George UGC 1`, `Bold Blake`, `Jane`, `Expressive Evan`, `Marianne - IA`, `Aaron`, `Modern Recipe Host - Voice 1`, `Willow`, `Cute Chloe - Friendly 馃槉`, `Rafael`, `June - Lifelike`, `Crisp Chloe`, `Slick Simon`, `Nassim - Informative`, `Baritone Ben`, `Maxwell`, `Ellie Faye - Excited 馃ぉ`, `Milani`, `Feisty Fiona - Excited 馃ぉ`, `Professor Dean`, `Rose - UGC - 1.mp4`, `Shona`, `Hudson Wilder`, `Ann - IA`, `Alastair Kensington`, `Oxley`, `Christina`, `Andrew Rizz `, `Peyton`, `Gerardo - Outdoor`, `Chloe - Lifelike`, `Stephanie`, `Anthony - IA`, `Signal - Voice 1`, `Luca`, `Lisa - Voice 1`, `T.W.Tucker`, `Jack Sullivan - Serious 馃槓`, `Winter`, `Mireia - Lifelike`, `Georgia`, `Stella`, `Masha - Lifelike`, `Charming Charles - Friendly 馃槉`, `Serenity`, `Annie - Excited`, `Ralph`, `Bethany`, `Dominic`, `Mason Finn`, `Leena`, `Veteran Victor`, `Tamara`, `Nik Public`, `Calm Chloe`, `Sevik`, `Reilly`, `Raul`, `Imposing Ian`, `Relaxed Ray`, `Dexter - Professional`, `Relaxed Rick`, `Edwin`, `Rupert Blackwood`, `Ginny`, `Hope` | Nama suara yang digunakan untuk memilih suara avatar. | | `audio_url` | `audio` | string (audio URL) \| null | no | | | Audio sinkronisasi bibir yang diberikan melalui URL file, yang memprioritaskan prompt dan suara jika tersedia. | | `talking_style` | | enum (string) | no | `stable` | `stable`, `expressive` | Gaya animasi ucapan: 'stable' menjaga gerakan tetap minimal, sedangkan 'expressive' menambahkan lebih banyak animasi. | | `expression` | | string \| null | no | | | Ekspresi yang ditampilkan pada wajah. | | `background` | | object {type, value} | no | | | Pengaturan untuk latar belakang. | | `background.type` | | enum (string) | no | `color` | `color`, `image`, `video` | Pemilihan jenis latar belakang. | | `background.value` | | string | no | `#FFFFFF` | | Konten latar belakang: warna heksadesimal jika jenisnya 'color', atau URL jika jenisnya 'image' atau 'video'. | | `resolution` | | enum (string) | no | `720p` | `360p`, `480p`, `540p`, `720p`, `1080p` | Preset resolusi untuk video: 360p, 480p, 540p, 720p, atau 1080p. | | `aspect_ratio` | | enum (string) | no | `16:9` | `16:9`, `9:16`, `4:5`, `5:4`, `1:1`, `auto` | Pilihan rasio aspek video: 'auto' meminta HeyGen membaca dan mempertahankan rasio sumber, menggunakan '16:9' jika tidak dapat membacanya.
