Uploading in 4K with DTube

Have you ever tried to upload a 4K video onto DTube? Last night I tried but got an error. This morning I am trying again. If the video does load this time I will link to that video. Nothing exciting in the video, just a test video. Would you be able to confirm if the video is in 4K? I don't have a monitor that can play 4K. Possibly DTube will downgrade the video file.

This is what the DTube upload page looks like.

Now the file has been uploaded. Let's see if it works.

Now I see an error

"File received. Adding to IPFS Datastore..."

This has been going on for 15 minutes so I give up. If you know the creators of DTube please forward this post to them. This was only supposed to be a test video upload. I am okay with the file not being uploaded correctly.
