Hey all, had a question about my video resolution on Pond5 after submission, actually on stock sites.
How do they determine the HD size from my 4K footage ? Since they automatically do that.
for example, if I uploaded something in 3840 x 2160 pixels, how do they determine what my HD video should look like ? Can I specify what i want my HD resolution should be ?

If you upload an aspect ratio other than 16:9, some (I think most) sites will convert to 2k (4k DCI to 2048x1080), some crop to HD.
 

Right. and the base price is $15. duh!

The "Good" thing for buyers is that selecting a large HD file that was down converted from 4K is usually a great detailed image highly available to manipulate in post. Maybe, this also in time make native HD (1920x1080) also a thing of the past? EDIT I mean that uploading a 400Mb 4K clip, produces an 800Mb HD file available for sale.

Hahah!

Uploading in P5 files, pricing start from $25 for HD and $50 for 4K, after that you set the price to the desired one. Uploading 2K initial suggested price is "custom" $15.

I have noticed that whatever I upload, let's say a 200Mb 4K file, the HD equilevant file is double the size 2x 200Mb= 400Mb. A large file with lots of information.
If I offer a native HD "red rose" and you offer a 4K downgraded option to HD same "red rose" file, yours willbeat mine in terms of quality. So my "HD" file goes legacy...
