I use Shutterstock for uploading all the images that I used to upload to Wirestock.
Anything that's not good enough for Adobe Stock.
Will do the same with Pond5 for video now.

I haven't gotten a response to my request yet,

but I checked my recent sales and they were indeed 4K subscriptions at 2.80$

I don't sell much as I don't have that many assets yet, but I had multiple 4K video sales in 4 days, usually I have the same amount in HD videos in a month or so.
My last 4K sale before the subscription change was actually many many months ago ....

I guess it's too early to say, but if total sales increase then I hope this will offset the reduction in returns per sale.

I can only assume that Adobe want's to maximize sale revenue and that they know what they're doing, but I'll keep observing, and uploading (in 4K)

Hi,
I just got the mail from Adobe so I sent them a reply asking for more information on royalties.

The websites for contributors and also for customers do not distinguish between HD and 4K.

If the rate for 4K will be the same as HD then I think I'll stop uploading 4K altogether. Most of my sales are HD subscriptions anyhow, with a few credit pack sales in HD every now and then.
