Video that codec in h.264 . mp4 can't play back correct in cubase 13


I can’t playback the video that I import in Cubase.
This video is codec in h.264 .mp4
My computer’s specification is
CPU: AMD Ryzen 7 5700G with Radeon Graphics
Memory: kingston and cuso 16gb 16gb 32gb 32gb
GPU: I use AMD Radeon Graphic that in the CPU to play video and use p106-100 to play video games
My project set up matches the frame rate of the video as well.
I don’t know how to solve this problem , so can anyone help me……

Cubase has a poor video handling system. Could your video be 4k or have a very high frame rate?

I always create proxies at low resolution (1920x1080 max) and with and intraframe codec like prores (422proxy).
With an intraframe codec you can go back and forth very smooth.

Yeah, the resolution is high(3840*2160 4k 60fps)……I will try your method, thank you.
