AI Videos for Social Media

Short-form platforms reward return viewers, and return viewers recognise people. That is the awkward part of using an AI short video generator for TikTok or Instagram: most tools give you a great-looking clip and a different-looking person every time you press go, which is fine for one-off memes and useless for building a channel.

Seven of the ten published video models accept character reference images, which is the mechanism that makes a recurring host possible. You render the character once, and every subsequent clip is generated with that image attached — Grok Imagine Video, HeyGen Video, Seedance 2.0 Mini, MiniMax H3, PixVerse C1, Kling O3, Kling V3.0, Vidu Q3, Seedance 2.0, Veo 3.1, Seedance 2.5.

Vertical is a render setting rather than a crop. Pick 9:16 at the shot level and the model composes for it, so faces are not clipped by the safe area and captions are not sitting on top of the subject.

Signing up puts 100 credits in your account, once, with no card. For a typical short story that is enough to go from your idea to a storyboard — the story brief, the script, the cast images and the shot plan — or, if you would rather, about 16 images in the image studio. A longer script or a bigger cast can use it up first, and the video itself is bought with credits.

Reelfo does not stamp a watermark on anything it renders. The compose step copies the video stream through untouched — there is no overlay filter in the pipeline to apply one.
