About video codecs YUV 4.2.0 v. 4.2.2


posted on 10th of july, 2014

Hi. Do you want to start selling video footage and don't know what camera to buy? Forget about prices, check this first! Take a SD Card with you and ask seller to let you shoot a small video. Come home and check video codec (use VLC for this, Tools - Codec information).

You will see something like Planar 4:2:0 YUV or Planar 4:2:2 YUV.

Tip how to do film-like video footage in daylight


posted on 18th of july, 2014

Hi. Another tips from your beloved king :)
As you know, recording at 24 fps will give a film-like look at recordings. Combine this with a shallow DOF and you have a piece of art, ready for sale.

Today tip is not about filming at 24 fps (only available on selected cameras), but about how to achieve a shutter speed of about 1/45. This because you want the denominator of your shutter speed to be approximately double the number of frames per second that you are recording. In other words, if you are recording at 24 frames per second, you want your shutter speed to be 1/45th of a second. Or at 30 fps --> 1/60. Shutter speed can have a very noticeable effect on the look of your video, when it comes to motion. A fast shutter speed such as 1/600th of a second will produce a series of crisp frames that have...
