Away_Exam_4586 · reddit · 2026-10-12
The open-source ComfyUINVIDIARTXVSRLongVideo project brings NVIDIA RTX Video Super Resolution into ComfyUI, optimized for long videos with disk-backed chunked processing that keeps RAM usage low. The screenshot shows parameters like scale 3.0, HIGIBITRATEHIGH quality, strength 1.0, and 48 frames per chunk — a 464-frame 2592×3840 video processed in 10 segments in about 27 seconds.
Features include AI upscaling, denoising, deblurring, H.264/HEVC NVENC encoding, audio preservation, and an integrated preview. Useful for locally batch-upscaling long AI-generated or real footage.
