RelayVSR

About

RelayVSR is a video upscaler from kopperx. Give it one finished video, such as a MiniMax H3 render or a clip you upload, and it returns a larger copy at 1080p, 1440p, or 4K on the short edge. It is promptless: the output size is the only choice.

The result keeps the source's frame count, its exact frame rate, the full aspect ratio, and the original audio track. In Sogni you pick the size and the right model is chosen for you.

Use it from the SDK

Send the video and the output size. Use the 2x model when the target is no more than twice the source's short edge, and the 4x model otherwise. The server probes the upload for its frame count, frame rate, and dimensions, and prices the job from those verified values.

const project = await sogni.projects.create({
  type: 'video',
  network: 'fast',
  modelId: 'relayvsr_x2_lightx2v_int8_convrot',
  positivePrompt: '',
  numberOfMedia: 1,
  referenceVideo: fs.readFileSync('./clip.mp4'),
  upscaleResolution: 2160 // or 1080, 1440: the output's short edge
});

const [upscaledUrl] = await project.waitForCompletion(); // MP4 with the original audio

project = await sogni.projects.create(
    type="video",
    network="fast",
    model_id="relayvsr_x2_lightx2v_int8_convrot",
    positive_prompt="",
    number_of_media=1,
    reference_video="clip.mp4",
    upscale_resolution=2160,  # or 1080, 1440: the output's short edge
)
print(await project.wait_for_completion())  # MP4 with the original audio

Frame count, frame rate, width, and height are optional; any you send must match the source. The RelayVSR guide shows which targets each source can reach and how to request a price estimate first.
