Acceleration effect after upscaling

[girzai]

Hi, Currently using a very simple WF for upscaling video with SeedVR2 but it's seems that after upscaling, the video is accelerate a lot, wondering if it's come from my settings or model ( tried both 3b and 7b model )

I need a picture of the entire workflow, the save node, the FPS might have been increased, that's why the video is speeding up.
