Many reasons exist as to why a good graphics card can affect video editing.
Using a better quality graphics card, otherwise known as a video card, can boost your computer's performance, increase productivity and allow you to fully explore your creativity when it comes to video editing.
Outputs
Graphic cards have various connectors that are visible on the back of the tower, each one connecting to specific cables. The most common are VGA outputs, DVI outputs and HDMI. These are where monitors or television screens can be plugged into and used to display images from the computer.
Interface
The graphics card interface is the section where the card is inserted or plugged into your motherboard. The most common types of this interface are AGP, PIC bus or PCI Express. A higher quality card will transfer data more efficiently between the computer and the graphics card.
Processor
The graphics processor of a video card is responsible for several important hardware specifications and is one of the most important factors in choosing a card for video editing. A more powerful processor will ensure video editing programs run smoothly and perform at higher quality.
Video Memory
Similar to the RAM found in the computer, a good graphics card should have RAM on the card itself dedicated to processing information related to graphics. This keeps the graphics from draining too many resources from the computer.
Cooling
In many computers, graphic cards consume the most electricity while producing the most heat. Higher quality cards will have more reliable or efficient heat sinks, heat pipes, or fans to prevent overheating and damage.
