Can you compress the vidio size please?
If you know how to use ffmpeg, here's the command I run pretty much all of Nohhun's videos before I stick them on my phone. It'll halve the resolution and convert the video from x264 to the smaller but less widely compatible x265 and also reduce the quality of the video by a bit, but the difference should be imperceptible. If you have it installed, just paste this into a text file, rename it from .txt to .bat and run it in the same folder as the mp4s you want to cut down in size.
for %%f in (*.mp4) do ffmpeg -i %%f -filter:v scale="trunc(iw/4)*2:trunc(ih/4)*2" -vcodec libx265 -crf 28 "%%f.mp4"
I think Nohhun's videos are absolutely massive relative to their quality because he's not rendering them very well. Despite the 4K resolution, they contain a ton of artifacting that ironically makes compression a pain in my experience.
