I'm trying to create a page with multiple videos in it, which is should be sync. I manage to play them at the same time using only one control. But right now, my goal is to give the user the ability to change the time or seeking the video.

Right now actually it is working if the video's length is short. Here's my current development https://stackblitz.com/edit/ngx-plyr-qilsdm

I'm using this video for dummy http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ForBiggerBlazes.mp4 it is working just fine i can change the time freely, it's a bit lag although it seems to be just fine.

But when I try using my video https://cdn.among.tv/vod/2021/0930/old-days-c1-2.mp4 it doesn't work.

I know maybe it's because the resolution of the video is different, but my task is use 1080p videos. Does anyone know a trick to overcome this?
