    Idea [I] Does system performance (in terms of cpu-gpu-...) affect quality of video output ?

    hello 

    does system performance (better cpu - gpu - hdd , ... ) affect the video output and video file quality ?

    in other words , does system with higher and better specs increase the video quality or its just about the render time decrease ? 

    for example if we render a project on an avid professional hardware using avid media composer and render the same project on a regular system with same software  , do we get same result ? (ofc if the both be able to render the project )  or the quality is better on the better system ?

    thanks for help .

    Hi,

    The quality is the same. With faster/more powerful hardware your renders/transcodes/whatever won't take as long, but they'll be the same quality as they would with a slower/less powerful system.

    Avid hardware also speeds things up, and can give you more options for output than a system without Avid hardware, but again the quality is not greater, only faster.

    One consideration is the use of the GPU for rendering.

    Previously when Avid launched it looked at a config file for supported graphic card/driver combo and would only enable GPU rendering for supported configurations. Thats now changed and only unsupported card/driver combinations are listed and therefore all cards are enabled for GPU rendering unless listed as unsupported.

    I have seen issues with subtle render errors when using unsupported cards for rendering in the past.

    So I'd say generally no the results aren't different for more powerful systems except when related to the GPU and its driver. Here a supported combination is the onlyn way to be sure errors aren't introduced or disable GPU rendering in the render settings.
