Pika H3 Flex questions, answered
Inputs, output quality, credits and sound.
Pika H3 Flex is Pika’s video-and-audio model built on MiniMax H3. It creates short scenes from text, endpoint frames or visual references. FastMoro AI is an independent creation platform, unaffiliated with Pika Labs.
This interface supports text, a first frame, a last frame or both, and reference-to-video with one to nine images. Use static JPEG, PNG or WebP images. Video and audio reference uploads are not included in this release.
480p and 768p are native outputs. The 1080p option generates at 768p and then upscales while preserving audio and frame rate. This interface does not offer 2K, 4K or separate audio-stem downloads.
The total depends on mode, duration and resolution and is shown before submission. A five-second text or image video uses 5 credits at 480p, 10 at 768p or 20 at 1080p. A five-second image-reference video uses 15, 30 or 40 credits respectively. Check your balance and the pricing page before generating.
Yes. Include what should be heard alongside what should be seen: dialogue, ambience, effects and music. Pika H3 Flex video contains synchronized stereo audio. Review pronunciation, lip movement and timing before sharing it.
Check identity, motion, small product details and any visible text. Use inputs you have permission to upload and review the applicable usage terms. Precise lettering, exact edits and identical results are not guaranteed.
