If you have ever downloaded videos of long duration to YouTube but now do not, you need to check your account for copyright strikes and complaints.
You can only upload long-duration videos to YouTube if your account is in good standing according to the YouTube Community Guidelines and your content is not blocked by Global Content ID.
If your video is larger than 128 GB, you can try compressing the video in the video editor before uploading it to YouTube . Doing so will reduce the video file size and still keep the video in high quality. Another way to compress videos on YouTube is to encode videos with H.264 codecs.
Good luck!
