[QUOTE="Owlsroost, post: 1250258, member: 83973"] The screen grabs below that line look like they are for a 720 x 480 frame size file, not 4k (look at the 'rcSource' and 'rcTarget' values). In theory, the 'biCompression' value should be 'DXVA' - but if you have the sys tray icon enabled for LAV Video and use it to open the property page it will tell you which decoder is in use ('Active Decoder: dxva2n' in the example below - it will be 'avcodec' if it is using software decoding): [ATTACH=full]199095[/ATTACH] I think there may be some confusion here about using GraphStudio with MP2 - what we need is to use the 32-bit version of GraphStudio in 'connect to remote graph' mode while MP2 is playing a file (run MP2 in windowed mode to make this easier). That allows you see the live graph that MP2 is using. Example using MP1 below (note 'biCompression' = 0x61767864 [dxva]): [ATTACH=full]199096[/ATTACH] To make the remote connect work, you need to drop 'proppage.dll' (attached) into the same folder that 32-bit GraphStudio is installed, then open an [B]administrator [/B]command prompt and type "regsvr32 proppage.dll" to register the dll. Then run GraphStudio and select 'Connect to Remote Graph...' from the file menu [/QUOTE]
