I think the undiscussed issue here is Ancestry's need to control their available server space and bandwidth. If they control the recording of the video, they control the resolution and length thereby controling the file size and playback requirement. Streaming video takes a huge hit on bandwidth. High resolution videos are especially large.
I agree it would be great to have historical high quality videos posted, but I don't see the incentive for Ancestry to add that feature under the current subscription structure. Would you be willing to pay more for that feature?
A thought would be to post your video on a streaming video service, like YouTube and post a link to it in your Ancestry Tree in a note. Doesn't that do almost the same thing?
