 ^ Video encoding    | Average Bitrate (Two Pass), Average Bitrate 4096 kb/s (about 1.8 Gb per hour)  |
-^ Pixel format      | Our source videos use **yuvj420p pixel format**, so we use the same for the final rendering.  |
+^ Pixel format      | Our source videos use **yuvj420p pixel format**, so we use the same for the final rendering (see the considerations below).  |
 ^ Bits per sample   | Our source videos use **8 bits per raw sample**, so we stay on this.  |
-^ Color range       | The **j** letter in the //yuvj420p// pixel format means that YUV values are stored as full 0-255 range (**8 bit**), as in JPEG. This is better than the so called //studio swing//, with Y in the 16-235 range and UV in the 16-240 range.  |
