Hey guys,
I've been shooting alot of 4k video lately and wanted to upload it to youtube.  I've offloaded the video files from my memory card to my PC, but when I upload the videos to youtube the only option they give me is 1080p for viewing.  I believe i'm shooting at 4k 25fps, and the video files show the correct information but youtube will not play it back at 4k.  What could I be doing wrong?

Thanks

It takes a little while for youtube to process the video for all resolutions.  Also depending on what you try to play the video on will have an impact on which resolutions they make available.

Did you check the rendered file properties for resolution?
