Video not working in Cubase 10.5 pro

So I have tried everything and I can pull in video to Cubase 10.5 pro but it will not work. You can see the video but it gets stuck. I have changed the video type and the codec but that has not made a difference. If I convert my mp.4 file to a low grade .mov it will work but the video quality is terrible. I’ve also tried messing with the different buffer settings and that didn’t help either. I’m on Windows 10 and I’m using 32 gigs of ram on an i7 pc. This is the only issues I have and I haven’t found any answers to fix it. I even finally called Steinberg and they said to just keep trying different different codecs and video formats till one works. Any help is appreciated!!!
