TopazVideoEnhanceV2 - ComfyUI Built-in Node Documentation

The Topaz Video Enhance V2 node breathes new life into video with powerful upscaling and recovery technology.

The Topaz Video Enhance V2 node breathes new life into video with powerful upscaling and recovery technology. It can increase the resolution of a video using different Topaz upscaler models, adjust the frame rate through frame interpolation, and apply creative or realistic enhancement settings.

Inputs

Common Inputs

Parameter	Description	Data Type	Required	Range
video	The input video to be processed. Must be in MP4 container format.	VIDEO	Yes	-
upscaler_model	The AI model used to upscale the video. The available sub-parameters depend on the selected model. Selecting "Disabled" disables upscaling.	DYNAMIC_COMBO	Yes	"Astra 2" "Starlight (Astra) Fast" "Starlight (Astra) Creative" "Starlight Precise 2.5" "Disabled"
interpolation_model	The AI model used for frame interpolation. The available sub-parameters depend on the selected model. Selecting "Disabled" disables interpolation.	DYNAMIC_COMBO	Yes	"Disabled" "apo-8"
dynamic_compression_level	CQP level used for video compression (default: "Low").	COMBO	No	"Low" "Mid" "High"

The following sections describe the sub-parameters that appear for each option of the upscaler_model and interpolation_model selectors. The "Disabled" options do not show any additional parameters.

Astra 2 Inputs

Parameter	Description	Data Type	Required	Range
upscaler_model.upscaler_resolution	Target output resolution of the upscale.	COMBO	Yes (when “Astra 2” is selected)	"FullHD (1080p)" "4K (2160p)"
upscaler_model.creativity	Creative strength of the upscale (default: 0.5).	FLOAT	No	0.0 to 1.0 (step 0.1)
upscaler_model.prompt	Optional descriptive (not instructive) scene prompt. Capping input at 450 frames (~15s @ 30fps) when set (default: empty).	STRING	No	-
upscaler_model.sharp	Pre-enhance sharpness: 0.0=Gaussian blur, 0.5=passthrough (default), 1.0=USM sharpening.	FLOAT	No	0.0 to 1.0 (step 0.01)
upscaler_model.realism	Pulls output toward photographic realism. Leave at 0 for the model default (default: 0.0).	FLOAT	No	0.0 to 1.0 (step 0.01)

Starlight (Astra) Fast Inputs

Parameter	Description	Data Type	Required	Range
upscaler_model.upscaler_resolution	Target output resolution of the upscale.	COMBO	Yes (when this model is selected)	"FullHD (1080p)" "4K (2160p)"

Starlight (Astra) Creative Inputs

Parameter	Description	Data Type	Required	Range
upscaler_model.upscaler_resolution	Target output resolution of the upscale.	COMBO	Yes (when this model is selected)	"FullHD (1080p)" "4K (2160p)"
upscaler_model.creativity	Creative strength of the upscale (default: "low").	COMBO	No	"low" "middle" "high"

Starlight Precise 2.5 Inputs

Parameter	Description	Data Type	Required	Range
upscaler_model.upscaler_resolution	Target output resolution of the upscale.	COMBO	Yes (when this model is selected)	"FullHD (1080p)" "4K (2160p)"

apo-8 Inputs

Parameter	Description	Data Type	Required	Range
interpolation_model.interpolation_frame_rate	Output frame rate (default: 60).	INT	Yes (when “apo-8” is selected)	15 to 240
interpolation_model.interpolation_slowmo	Slow-motion factor applied to the input video. For example, 2 makes the output twice as slow and doubles the duration (default: 1).	INT	No	1 to 16
interpolation_model.interpolation_duplicate	Analyze the input for duplicate frames and remove them (default: False).	BOOLEAN	No	True False
interpolation_model.interpolation_duplicate_threshold	Detection sensitivity for duplicate frames (default: 0.01).	FLOAT	No	0.001 to 0.1 (step 0.001)

Important Constraints:

• At least one of upscaler_model or interpolation_model must be enabled. If both are set to "Disabled", the node raises an error because there is nothing to process.
• The input video must be in MP4 container format.
• The "Astra 2" model is limited to 9000 input frames. When a prompt is set, the limit is 450 input frames (~15 seconds at 30 fps). The node raises an error if the video exceeds the applicable limit.
• upscaler_model.upscaler_resolution is required whenever an upscaler model other than "Disabled" is selected. "FullHD (1080p)" targets a 1080p result and "4K (2160p)" targets a 2160p result; the exact output width and height are computed from the input aspect ratio, capped to a maximum long side of 1920 or 3840 pixels respectively, and rounded to an even number.
• interpolation_model.interpolation_frame_rate is required whenever interpolation_model is "apo-8".
• Very large files are not currently supported; uploads are limited to a single part, otherwise the node raises an error.
• Several parameters (sharp, realism, interpolation_slowmo, interpolation_duplicate, interpolation_duplicate_threshold) are marked as advanced in the UI and may be hidden by default.

Outputs

Output Name	Description	Data Type
video	The enhanced video after applying the selected upscaling and/or interpolation filters.	VIDEO
