Pika H3 Flex was made for tinkering like a creative pro. Generate a 15-second clip with a full soundtrack in as little as 7 seconds, export the audio as separate stems, and go up to 4K when you find the keeper. Use up to 12 references across image, video, and sound to get the exact clip you want, or to edit it with precision.
A 15-second clip with its full soundtrack can be ready in as little as 7 seconds. Try more ideas, compare more takes, and keep the one that works.
Every sound on its own track
Export three separate audio stems: Dialogue, Music, and Effect. Effect includes sound effects, Foley, and ambience. Turn the music down, swap the voice, or remix it in your own editor.
From draft to 4K
Pika H3 Flex has resolutions from 480 to 4K. Select draft mode to explore quickly at lower resolutions, then take it all the way to 4K when you’ve nailed the shot.
Guide it with your own references
Add up to 9 images, 3 video clips, and 3 audio tracks to one generation. Show it the face, the outfit, the location, and the voice, then tag each one in your prompt to say what it's for.
Edit anything in the shot
Change a character, an outfit, an object, or the whole background with a prompt or a reference image. You can also add new elements or remove the ones you don't want.
Frequently Asked Questions
How long can a Pika H3 Flex clip be?
Any whole second from 5 to 15. Every route uses the same range, and length is priced per second of output.
How do the three routes work?
What is attached decides. An empty attachment row renders from text alone; exactly one image becomes the first frame; anything more — extra images, a clip, an audio track — runs as an ordered reference set.
How many references can I attach?
Up to nine images, three video clips and three audio tracks in one run, twelve in all. Clips run 2 to 15 seconds each and at most 15 seconds combined per kind; a set that runs over is flagged before you spend anything.
Does every clip have audio?
Yes. Pika H3 Flex renders its own soundtrack on the text, frame and reference routes alike, so there is no audio switch to set.
Which resolutions and aspect ratios are supported?
480p or 768p on every route. Aspect covers 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16 and 9:21, or Auto, which follows the first frame when there is one and 16:9 otherwise.
Can I use reference audio on its own?
No. Reference audio rides alongside a reference image or clip — an audio-only set is held back before it is submitted.
How much does Pika H3 Flex cost?
A 5-second 768p video costs about 10 credits, and 480p about 5. On the monthly Starter plan ($10 for 900 credits) that is approximately $0.02 per second at 768p, so 900 credits cover about 90 five-second clips. Yearly plans are about 20% less. Final credits vary by length and settings; check the quote before generating.
Is Pika H3 Flex on the Free plan, and do videos have a watermark?
Yes. Every model and app is on every Pika plan, Free included. Free has no monthly credits, so you buy a credit pack to generate. No Pika plan adds a watermark, and the commercial license starts with Starter at $10 a month. Current plans and credit packs are on pika.art/pricing.
