In VMR7 is short for Video Mixing Renderer 7 VMR7 is a newer renderer that is generally much faster than the old Video Renderer When the driver is running in Direct Mode VMR7 uses an efficient DirectDraw configuration to render with almost no CPU overhead especially when YUY2 video is used When the driver is running in PostProcessing Mode DirectDraw is not used but it is still the fastest renderer Unfortunately VMR7 is not the default video renderer in building a filtergraph an application must explicitly ask for VMR7 in its graph for it to be used This process causes many simpler applications to render video much less efficiently VMR7 works best with YUY2 video and there is usually little reason to use any other format It will however work fairly well with the RGB format usually RGB32 that matches the current screen depth We recommend letting DirectShow choose the video format It generally makes the correct choice In particular on some usually older systems if two video frames are to be rendered with VMR7 at the same time only one can be YUY2 other s are RGB with a conversion filter inserted into the graph if necessary We do not provide an RGB24 option on the preview pin for use with 24 bit screens because on at least some display adapters the rendering of RGB24 to VMR7 is incorrect Note VMR7 cannot be used when closed captions are to be rendered from the driver s DShow standard CC or VBI pin use
