720p vs 1080p AI Video: Costs and Decision Guide

Direct answer: Choose 720p for cost-aware motion and composition tests when it is sufficient to judge the result. Move to 1080p when the creative direction is approved and the delivery destination requires it. A higher resolution costs more, but it does not repair source-image drift, a vague prompt, or the wrong crop.

Five-second 720p versus 1080p prices

FLUX 3 also has a 720p draft setting at $0.30 for five seconds. There is no 1080p draft option in magicdoor.ai. FLUX generated audio does not currently change its customer price.

These values come from quoteVideo: per-second rate multiplied by five output seconds. The rate card is:

A practical decision rule

1. Define the destination. Know whether the final placement asks for 16:9, 9:16, or 1:1 and whether 1080p is actually required.
2. Test the direction. Use five seconds at 720p when it is enough to evaluate composition and motion.
3. Fix creative problems first. Change the prompt, source image, crop, or movement before increasing resolution.
4. Review the new quote. The creator shows the full price before every generation.
5. Generate the delivery version. Choose 1080p only after the direction is worth the higher per-second rate.

This is a workflow recommendation, not an unsupported quality or speed benchmark.

Resolution does not solve these problems

• Source-image drift: reduce subject and camera motion, and use a cleaner first frame.
• Product, logo, or text changes: simplify motion and inspect every frame; exact preservation is not guaranteed.
• Wrong crop: prepare the source for 16:9, 9:16, or 1:1 before generating.
• Chaotic action: reduce the brief to one subject, one main action, and one camera move.
• Missing generated audio: choose Kling 3.0 or FLUX 3 and enable audio. Wan 3 has no generated-audio claim.

The AI video prompts guide covers prompt diagnosis. The image-to-video guide covers source preparation and drift.

Model boundaries still apply

Resolution does not change each model's duration ceiling:

• Wan 3 supports 5-30 seconds.
• Kling 3.0 supports 5-15 seconds, with separate silent and audio rates.
• FLUX 3 supports 5-20 seconds, optional generated audio, and 720p draft.

All three accept text plus one optional uploaded or saved starting image. Text-only runs expose 16:9, 9:16, and 1:1; with a starting image, Wan 3 and Kling 3.0 follow the source framing while FLUX 3 keeps the framing selector available. For model-level capability choices, use the AI video generator guide.

Access, retries, and privacy

Only active or trialing subscribers can generate. Usage comes from included credit or account balance. Each new creative attempt has its own quote; you pay only for a saved video, while provider or delivery failures release the reservation. magicdoor.ai shows the full quote before generation. Up to three jobs can reserve funds concurrently. Finished videos remain private until deleted.

FAQ

Should I generate AI video at 720p or 1080p?

Use 720p while testing motion, composition, and prompt direction when it meets your review needs. Choose 1080p when the direction is approved and the delivery destination requires it. Resolution alone does not fix prompt or source-image problems.

How much more does 1080p AI video cost on magicdoor.ai?

For five seconds, Wan 3 costs $0.25 at 720p and $0.50 at 1080p. Kling 3.0 silent costs $0.84 and $1.12, while audio costs $1.26 and $1.68. FLUX 3 normal costs $0.85 and $1.45; its 720p draft option costs $0.30.

Does 1080p prevent source-image drift or cropping?

No. Resolution changes output dimensions and price, but it does not guarantee product, logo, text, face, or crop fidelity. Fix the prompt, source image, motion, and aspect ratio before paying for a larger output.
