Which model is best for social media videos?

Hailuo 2.3 is the cheapest way to test an idea at 36 credits for five seconds. PixVerse C1 at 49 is the cheapest that will hold a recurring character. For hero content, Kling V3.0 at 95 or Veo 3.1 at 300.

Can I create vertical (9:16) videos?

Yes. All video models on Reelfo support 9:16 vertical output natively. Select the aspect ratio before generating and the AI composes the scene optimally for vertical viewing.

How do I add music or voiceover to AI videos?

Reelfo Studio supports audio overlay. Generate your video clip, then add music or voiceover in the timeline. For lip-synced speech, use the Lipsync Studio feature to match audio to characters.

Can I use AI videos in paid social media ads?

Yes. All videos generated on Reelfo paid plans can be used in paid advertising across all platforms. Many brands use Reelfo to produce ad creative at scale for testing and campaigns.

How many videos can I produce per day?

There is no daily cap — output is limited by your credit balance and nothing else. Credits are $0.01 each, and a five-second clip runs from 36 credits on Hailuo 2.3 to 300 on Veo 3.1, so a $10 top-up is roughly 27 cheap clips or three expensive ones.

Why a recurring face beats a better clip

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 — MiniMax H3, PixVerse C1, Grok Imagine Video, 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.

What a week of posting costs

Credits are a flat $0.01 and video bills per second, so the arithmetic is unusually easy to do in advance. These are eight-second vertical clips, one per day.

Derived from the live registry at $0.01 per credit. Cheapest six models shown; the full roster runs up to Veo 3.1.

The free version, honestly

Signing up puts 100 credits in your account, once, with no card. That is enough for the script, character and shot-list stages plus about one keyframe — it is a look at the pipeline, not a free finished reel.

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.
