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://zcusa.951200.xyz/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://zcusa.951200.xyz/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.
