Video play 8k into Video texture

Hi Folks,
simple and easy i want to use videoPlayer (via URL option) to render an 8k h264 mp4 into a render texture. 4k is working fine but 8k makes unity editor crash, without any notice.
If I try to import the files as vido clip, i get the error:

WindowsVideoMedia error 0xc00d36b4 while reading [[I]path to the video[/I]].mp4



Context: Setting media type for first video stream

Error details: The data specified for the media type is invalid, inconsistent, or not supported by this object.

Track types:

   Audio Track, type: %10%16

   Video Track [8192 x 4096], type: H264

      Resolution exceeds the Microsoft Media Foundation  decoder limit of 4096 x 2304 on Windows 8 and above.



UnityEditorInternal.InternalEditorUtility:ProjectWindowDrag(HierarchyProperty, Boolean)

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

excuse me, microsoft?! my vlc player plays the videos nicely by the way.
So, what do i do? Instal some new h264 codecs into unity? if so, how?

thanks
