4k, Full HD, HD

  • 20GB/hr [1]
  • Full HD takes about 8 GB/hr. [2]
  • HD takes about 4 GB/r

Full HD

  • Full HD is 2.1 Megapixel - [3]
  • 1 Gig card stores 1000 pictures, or 30 minutes at Full HD 30 fps
  • Standard cheapo 32G cards - 16 hours.
  • One full day of storage is 43Gig.
  • Cheapo USB sticks are $3/32 Gig - [4]
  • $10 from China for 256 gig - [5]

Completely Depends on Compression and Bitrate

4k 60 fps:

One picture at 4k - also depends:

General Considerations

  • Think of 8 Megapixel as 8MB.
    • By this figure, 60 fps, one minute of it, is 30 GB.
    • Thus, video must be compressed naturally by cameras, otherwise image size is too large.
  • 4k appears to be overrated. Cinema is 2k - full HD. [7]
  • Frame rate for TV and Movies - 24 fps. Sports and news - 30 fps - [8]
  • Use Handbrake to compress videos by up to 10x.
  • Case for 4k - you can get 8 MP stills from video, but only 2 MP images from Full HD video. [9]

Conversion

  • VLC converts from 4k to full HD - [10]
