ComfyUI Node
FlashVSR Postprocess
Postprocesses stock Wan VAE output by trimming tail-padding frames to the original frame count and removing the right/bottom padding added for 128-pixel spatial alignment. FlashVSR's official causal layout starts directly at source frame zero. Fast AdaIN and low-frequency wavelet color correction are optional.

Inputs (7)
| Name | Type | Default | Description |
|---|---|---|---|
| images | IMAGE | Decoded padded frames from stock VAE Decode. The node removes duplicated tail frames and right/bottom spatial alignment padding. | |
| video | FLASHVSR_VIDEO | Prepared-video metadata used to restore the requested frame count, width, and height. | |
| color_correction | COMBO | off | off preserves the VAE output. adain is the fast option: it matches each frame's per-channel mean and contrast to the resized input. wavelet_quarter_res transfers spatially varying low-frequency color at quarter width and height and is the practical wavelet option. wavelet_full_res performs all five blur passes at the complete output resolution for an exact but much slower result. |
| color_chunk_size | INT | 41–64 | Frames color-corrected together. Larger batches reduce per-frame overhead; 1 minimizes temporary memory. This also batches AdaIN when that mode is selected. |
| color_device | COMBO | auto | Device used by AdaIN/wavelet correction. auto uses a CUDA GPU when available and otherwise CPU. GPU work is bounded by color_chunk_size and uses FP16 workspaces. |
| inplace_correction | BOOLEAN | true | Correct the decoder IMAGE tensor in bounded chunks instead of allocating a second complete video. Disable only when the uncorrected decoder output is also used by another workflow branch. |
| profile_stages | BOOLEAN | false | Print wall time and per-stage color-correction timing for transfers, downsampling, lowpass, upsampling, clamping and output transfer. |
