PrunaPVideoUpscaleNode - ComfyUI Built-in Node Documentation

Pruna P-Video Upscale enlarges a video to 720p, 1080p, 2K or 4K while keeping its aspect ratio and audio track.

Pruna P-Video Upscale enlarges a video to 720p, 1080p, 2K or 4K while keeping its aspect ratio and audio track. The clip is sent to Pruna, the prediction is polled, and the upscaled video is returned. A source that is already at or above the target size keeps its dimensions and is only enhanced.

Inputs

Parameter	Description	Data Type	Required	Range
video	Video to upscale, up to 512 MiB. Videos larger than 10 megapixels can only be sent to the 2K or 4K target.	VIDEO	Yes	Up to 512 MiB
target	Output pixel area: 720p is about 0.9 megapixels, 1080p 2.1, 2K 3.7 and 4K 8.3. The longest clip is limited by the target: 2400, 1200, 600 or 300 frames, about 100, 50, 25 or 12.5 seconds at 24 fps (default: “1080p”).	COMBO	Yes	”720p" "1080p" "2K" "4K”
fps	Output frame rate (default: “source”). “source” keeps the rate of the video, up to 60; a higher rate is interpolated. Output above 30 fps costs twice as much.	COMBO	Yes	”source" "16" "24" "25" "30" "48" "50" "60”
turbo	Faster upscale with softer detail, at the same price (default: false).	BOOLEAN	No	true false

Parameter Constraints

• The clip must be 512 MiB or smaller, measured after it is re-encoded to H.264 MP4.
• The frame limit is counted at up to 30 fps: 2400 frames for 720p, 1200 for 1080p, 600 for 2K and 300 for 4K. A longer clip needs a lower target, a lower fps, or a shorter cut.

Outputs

Output Name	Description	Data Type
video	The upscaled video with its original audio.	VIDEO
