FAQ
OmniHuman 1.5 FAQ
What is OmniHuman 1.5 best used for?
OmniHuman 1.5 is designed for a focused image-and-audio workflow: one portrait supplies the subject, and one voice track drives the resulting performance. It fits presenter clips, character narration, and short talking-subject videos better than a general prompt-to-video task.
Which portrait and audio files can I upload?
Upload exactly one JPEG, PNG, or WebP image up to 10 MB and one MP3, M4A, WAV, AAC, or OGG audio file up to 10 MB. The verified audio duration must be greater than zero and strictly less than 60 seconds.
How are OmniHuman 1.5 credits calculated?
Rivya uses a rate of 27 credits per verified audio second. The decimal duration remains part of the full calculation, and only the reservation total is rounded up to a whole credit. When valid actual usage no higher than the reservation is reported, Rivya settles to it; missing, invalid, or higher-than-reserved usage remains in reconciliation instead of triggering a hidden extra charge.
What does fast mode change?
Fast mode prioritizes shorter processing time with a possible quality tradeoff. Leave it off for a quality-first run, and turn it on when turnaround matters more for an early test.
Can I add a prompt to the portrait and audio?
Yes, but it is optional and limited to 300 characters on Rivya. The current prompt path accepts Chinese, English, Japanese, Korean, Spanish, or Indonesian text; the portrait and audio remain the required inputs.
What can I create on this OmniHuman 1.5 page?
Create an audio-driven character video from exactly one portrait image and one audio clip. The subject can be a person, pet, or illustrated character, and output can be 720p or 1080p.
What should I prepare before generating?
Choose a clear portrait that already represents the subject you want to keep, then prepare the final voice take. The audio must be shorter than 60 seconds, and both files must pass upload checks before generation.
Which settings matter most?
Choose 720p or 1080p, decide whether to use the faster processing option, and leave the seed at -1 for a random result unless you need a more repeatable comparison.
Do I need to sign in, and how do credits work?
The details are public, but uploading and generating require sign-in. OmniHuman 1.5 costs 27 credits per verified audio second, with only the final calculated total rounded up.
When should I open the full Studio?
Stay here to test one portrait and one voice track. Open Studio when you need saved takes, several characters, repeated voice versions, or a longer production workflow.
