HEIC is converted in browsers that support it. Use a clear face and upper body.
Clip duration is the video length; processing time varies. Follow progress and download your MP4 in My videos.
Create an original street-freestyle scene with the consenting adult from the reference. Preserve their recognizable face and outfit. An adult partner holds a portable speaker at waist height. The performer looks toward the speaker, makes two alternating shoulder bounces, gestures to a loose spectator circle, then pauses. Medium-wide steady framing, visible hands, restrained background movement. No real-artist face or voice imitation, text or logos. A new interpretation, not original footage.

The idea behind the trend
The name refers to AI remixes inspired by Bulin 47’s street freestyle with Kevin Wai. The recognizable ingredients are the shoulder-led performance, a nearby partner with a portable speaker, and a watching crowd.
A remix puts your character at the center of the selected video. Your photo supplies the appearance; the video supplies the scene, camera and movement. Review the result for changes to faces, hands and surrounding details.
Keep the exchange.
Make the performer your own.
From photo to performance
Choose one clear character photo. Keep the face, shoulders and outfit visible. Use a photo you have permission to process; prepare an upright character image first for a pet remix.
Choose Fan freestyle or Performer remix for 15 seconds, or Character bounce for 6 seconds. We supply the source video; you only upload your photo.
Sign in with your email and password. Choose 720p or 1080p, review the duration and credits, then generate. Follow progress and download your private MP4 in My videos.
One-time credit packs, no subscription. Choose 720p or 1080p subject replacement. No free generation allowance.
A little movie magic
1 15-second video at 720p
A 15-second 1080p video needs 30 credits.

Video counts use this pack alone and the full 15-second quote. Credits can also be used for shorter videos. Buying credits does not start generation. Return to your selected video and choose Generate. We reserve the quoted credits; a shorter completed video returns the unused difference. Taxes, if applicable, are shown at checkout.
Watch. Plan. Recreate.
Upload one photo to replace the central performer in a 6- or 15-second template. Keep its scene and movement; choose quality and review the credit quote.
Read the guideThe most useful portrait clearly shows the face and the body area involved in your chosen motion. Match it to the reference rather than using a tiny face crop.
Read the guideYour source video supplies the scene and movement; your photo replaces its central performer. The optional upload accepts MP4 or MOV, 3–15 seconds, up to 20 MB, in 9:16 or 16:9.
Read the guideA pet preset prepares an experimental idea. A human subject-replacement sample does not establish reliable animal anatomy or successful pet output.
Read the guideAn original character works best as a coherent visual design with a movement it can plausibly perform. Keep the silhouette and visible joints readable.
Read the guideA useful prompt describes appearance and scene while the reference supplies movement. Keep the first brief short enough to review and revise.
Read the guideFind the stage where the problem happens before changing the prompt. A local preview issue, a provider failure, and an imperfect result need different checks.
Read the guideA usable export needs a checked video file and a checked audio track. Subject replacement and a public video link do not establish music or footage permission.
Read the guideBefore you start
Upload one photo and choose a fixed effect. Your photo replaces the central performer while the template supplies the scene and movement. Choose 720p or 1080p, review the duration and credit quote, then generate with your account and paid credits. Bring your own moves remains available under Advanced workflows.
Yes. The default generator needs only your photo. Fan freestyle and Performer remix use 15-second templates; Character bounce uses a 6-second template. The platform supplies the source video and replaces its central performer with the subject in your photo.
You can prepare those ideas here. A pet usually needs an upright stylized character image before human motion can be applied. Pet and mascot results have not been tested by this site.
The performer and speaker partner workflow has separate photo A and photo B slots for composition preparation. It does not replace two identities in a single video or generate a duet.
Audio is not guaranteed. Character bounce uses a silent reference. Review the sound in the finished video and use audio you have permission to publish.
Preparing a scene brief and reading the guides costs nothing. Subject replacement is priced at 1 credit per second for 720p or 2 credits per second for 1080p. Credit packs cost $4.99 for 20 credits, $12.99 for 80 credits and $24.99 for 200 credits. No free generation is offered. One-time credit checkout is available.
The 6- or 15-second duration is the finished clip length, not the processing time. Processing time varies with the provider queue and the request; no fixed completion time is guaranteed. After submission, check My videos for progress and download the MP4 when it is ready. Buying credits does not start a video: return to the generator and choose Generate. If submission is uncertain, check My videos before retrying to avoid creating a second task.
The $4.99 pack adds 20 credits. With no existing balance, that covers one 15-second video at 720p (15 credits), or three 6-second Character bounce videos at 720p (6 credits each). A 15-second video at 1080p needs 30 credits, so this pack alone is not enough for that selection. Check the quote before buying; unused credits remain in your account.
Selecting references and saving a text brief stay in your browser. Generate uploads your prepared photo and the selected motion template to private site storage and Kie for AI processing. Completed and failed task files are scheduled for site removal after 30 days; unresolved requests stay for review. See Privacy for details.
