problem loading video captures

I just countered this problem myself starting a few days ago. Distressing to see that people have been dealing with this problem longer than I have. As I was writing this comment I noticed that some of my captures have loaded back to my capture section
on the Xbox app and Xbox but it shows my most "recent" video was 71 days ago. I guess it's still loading the rest. But yes I don't know how this problem came to be but I hope it gets fixed for everyone.

Same problem. I can clip other games, but Fortnite only capturing a still not video. Audi is there, a still capture, but no video. I've repaired and reset game bar, still doesn't work.

Hi,

You may check this one out: AVerTV CaptureHD H727. It's an inexpensive PCIe capture card for desktop PC. Easy to install, but you need to have a powerful PC for processing and loads of storage space for captured video. Otherwise looks promising.
Good luck!

I use a capture card because of this and another problem I encountered is that if you capture 4k HDR videos on external when you upload them to Youtube only the 4k aspect of it uploads but not the HDR and the video ends up looking weird
