Specifications for 2K, 4K and 5K

Dear Marcus,

I would like to upload some 2K, 4K and 5K clips. Could you please suggest the technical specifications such as dimensions, FPS, codec, max file size and price?

Additionally, should any specific tags be added to them to help buyers fine them? Should I put 2k, 4k, 5k in the metadata?

Well, site-savvy buyers would simply put "linesgt:1080" into their search, but I doubt this is common knowledge. Besides, being able to speciffically search for "above HD" footage would be a great feature.

You are right, varius. Still I hesitate because I cannot estimate the market value. The production takes humongous computer resources and storage area. I don't know if it's worth it to be a pioneer.

To select Cinema 2K (2048x1556) clips use this - lineseq:1556

I still cannot figure out what codec was used. Also: most of the postesr used 24 or 25 fps; However large screens use >> 30 fps. So what's the point? Is the bit stream per second much higher, for example 70 mbps?

For Cinema 2K clips the specifications are standard and EXACTLY these:

- frame rate: 24 fps
- size: 2048x1556
- bit rate depends on the contents and easily could be ~500 Mbps. For my growing flowers in PNG+ format bit rate is around ~200 Mbps
- format: is QuickTime Movie
- for clips with progressive scan field rendering the compression is Photo-JPeg
- for clips with interlaced field rendering the compression is Motion JPeg-B
- for my time-lapse clips with transparent background I use the PNG+ compression

Hey Zygis, I am curious as to what model camera(s) you use? I have always admired your flora time-lapse footage. :) And no - I won't even start trying to do this as here in the desert such flora refuses to grow. :)

Hello Andreas,

Currently for time-lapse I use the Canon Powershot S5 IS (it is 8 Mpix camera, so I can easily make 2K). Also for some very detailed like this: https://www.pond5.com/de/stock-footage/697088 I use the Canon D5 MarkII and older Nikon or Olympus.

So far there are no single 4K (4096x3112) clip in Pond5 library - search for lineseq:3112 returns zero

BTW: you can grow cactuses in desesrt, they bloom https://www.pond5.com/de/stock-video-footage/cactus-zygistudio.html

lol so many people insist on the standard for 2k, some film scanners use 1536 some use 1556, I think 2048X1080 is cool. Some people want wide screen others don't.

There really is no set standard because those 2k measurements etc were made for film, and film isnt as exact as digital cameras.


As for 4k and 5k, I would not do it.... There was an experiement at universal studios preformed by a few IMAX technicians (4k is imax) . The experiment was not favorable to IMAX..... The experiment involved projecting very large black and white squares on the screen that doubled in population and shrank in size during the course of the video until each black square became a pixel on a 4k projection. At 4k people could no longer see the black and white squares, they saw gray....Think about that. People could not see that close on a big screen. Human beings cant make out the density of pixels in a 4k projection, we just cant see the difference. 4k will never be a standard IMO.
