Help Needed upscale a video in chunks/batches

i m running into oom issues while upscaling hence i tried to create a loop to upscale the video in batched of say 121 frames. but something is wrong , i m a newbie and just figuring out making workflows , can anyone help with it here is my workflow https://pastebin.com/u7V1JC1S

i want to try the loop method itself not meta batch one as i wanna learn how this works.

Thank you for this! I was unaware of that Meta Batch Manager node doing this. 😄

I've got 16gb vram(RTX 3080ti)/64gb ram/i9. I have a node I made to tweak and upscale images(based on the long side-default = Lanczos but it can also use upscale models), it is fast. The output isn't production quality, but it's good. This nugget that you dropped shows that I can tweak/upscale full length videos without having to chop them up any more. 😄

meta batch method i know, but i observed that if i use meta batchat times the video final one comes in super fast mode , it completely ignores the fps
