The following is a brief introduction to the difference between HD and SD corporate promotional films, let's look at it together;
The distinction between HD and SD comes first from the video effect you can see. Because of the different bandwidth of image quality and channel transmission, digital TV signal is divided into HDTV (HDTV), SDTV (standard definition TV) and LDTV (ordinary definition TV). From the visual effect of HDTV specifications for the highest, its image quality can reach or close to 35mm widescreen films level, it requires video content and display device level resolution of more than 1000 lines, resolution up to 1920×1080.
In terms of quality, the resolution of HD is roughly 4 times times the size of a traditional analog TV, and the sharpness of the screen and the color reduction are much better than traditional TVs. The 16:9 widescreen display also brings a wider visual enjoyment. From the audio effect, HD TV shows will support Dolby 5.1-channel surround sound, while HD movie shows will support the Dolby 5.1 true HD specs, which will give us a super shock of hearing enjoyment.

And now the market on the high definition of HD and high-definition, the true meaning of HD is a 1080p or more than the size of the video, quasi-HD is not up to this requirement. Many enterprises and promotional film production companies, the measurement of HD and SD standards only in the price, in fact, this is a misunderstanding. Promotional film, SD and HD in the price is actually not much difference, nothing but the use of high-definition cameras, post-production also use high-definition editing software.
Here is a misunderstanding, it must be clarified, and does not necessarily say that the quality of high-definition HD is certainly better than SD. A corporate propaganda film in the quality of good or bad or to look at the pre-planning, production and other full operating standards. HD and SD are just the difference between the screen size and the fine degree of the screen, these are just the difference between the production means and the use of equipment.
