|mfmp4srcsnk.dll - Large delay when right-clicking on Explorer file/folder.|
Explorer memory leak with very large prores .mov files recorded on a Video Devices / Sound Devices PIX 250 Recorder. Just selecting multiple files would use 40+GB of ram and pause/hang explorer while calculating metadata. Disabling this is not really the right answer as it affects some other features, so disabling it just for .mov is possibly better but I have yet to investigate that option.
