VideoCapture API in Unity3D on HL2 only returns Legacy Resolutions under SupportedResolutions

Using VideoCapture API I am able to record videos on the HL2 for resolutions 2272x1278 and 896x504. I am encountering the same problem as described here: https://forum.unity.com/threads/videocapture-returns-invalid-resolutions-for-hololens-2-camera.838822/

It seems like only resolutions listed under the Legacy profile are returned as supported ones. How can I record videos at different, supported resolutions on HL2 though?

Thank you!

    Hello, Welcome to Microsoft Q&A,

    You can use MediaCapture API to expand your options for camera profiles and video capture resolutions on the HoloLens device. To  capture videos with MediaCapture API, please refer to Basic photo, video, and audio capture with MediaCapture - UWP applications | Microsoft Learn.

    To check all the profiles and resolutions supported by HoloLens 2 device, please refer to https://learn.microsoft.com/en-us/windows/mixed-reality/develop/advanced-concepts/locatable-camera-overview - hololens-2.

    To learn how to select a profile based on supported resolution, please refer to - https://learn.microsoft.com/en-us/windows/uwp/audio-video-camera/camera-profiles - select-a-profile-based-on-supported-resolution-and-frame-rate.

    I did some tests with two supported resolutions: 1952x1100 and 1280x720, both of which worked successfully.
