480p plus AI upscale vs native 720p: quality and cost compared

On RelayDance, native 720p Seedance 2.0 output costs about $0.190 per second. No 480p tier or AI upscale price is published, so a 480p plus upscale pipeline cannot be priced from RelayDance rates alone. Native 720p is generated at its target resolution in one billed request. An upscaled 480p clip adds a separate upscaling step with its own cost. For predictable cost and quality, native 720p is the option with a published rate.

What does native 720p cost compared with other Seedance tiers?

Native 720p on Seedance 2.0 costs about $0.190 per second, which works out to about $1.90 for a 10-second clip. The table below lists the per-second rates published on the relaydance.com/models page. The 10-second column is simple multiplication of those rates. The 4K figure is converted from its per-clip price of about $4.90 per 5-second clip. Billing is pay-as-you-go per generated video. According to relaydance.com, “Failed or errored requests are never billed,” so a failed 720p attempt adds nothing to the total. Rates can change, so check the models page before you budget a project.

How does 480p plus AI upscale compare with native 720p on quality?

Native 720p frames are produced by the video model at 720p, while an upscaled 480p clip has its added pixels reconstructed afterward by a separate upscaling model. Native 720p therefore reflects the generation model's own output at that resolution. With an upscaled clip, the result depends on two models: the 480p generator and the upscaler. RelayDance does not publish a 480p rate or an upscaling service, so any upscale step would run outside the RelayDance API and carry its own processing cost and time. If 720p is not enough detail, you can request a higher native tier instead of upscaling. Seedance 2.0 1080p is about $0.470 per second, and native 4K is about $4.90 per 5-second clip, according to the relaydance.com/models listing.

How do you request native 720p through the RelayDance API?

You request native 720p by submitting a video task to POST /v1/video/generations with the resolution set in metadata. The API is OpenAI-compatible. According to the official relaydance.com/docs, “Set base_url to https://relaydance.com/v1 and keep your OpenAI SDK”. Authenticate with Authorization: Bearer YOUR_API_KEY, using a key created at relaydance.com/console. The request body includes model, prompt, seconds, and metadata fields such as ratio, resolution, generate_audio, and callback_url. Clips can run up to 15 seconds. To get the result, poll GET /v1/video/generations/{task_id} until the status is succeeded or failed. Alternatively, set metadata.callback_url and the final state is POSTed to your server. See the docs for full parameters.
