Some TVs, from brands including LG, Samsung, and Vizio, have a feature called Filmmaker Mode, which automatically adjusts the TV’s settings to show films as the directors intended when a movie is played. Instead, we’ve found that modes with names such as “cinema,” “movie,” and “expert” generally provide the best results. Also stay away from the “vivid” and “dynamic” modes, which tend to overemphasize contrast and sharpness and lower brightness too much. It could artificially boost brightness, contrast, and colors, and turn on motion smoothing (more on that below). Our advice: Don’t choose “sports” mode for watching sports-or for anything else. colorKey = Ī = ColorTranslator.All TVs now come with a menu of picture modes with names such as “vivid,” “natural,” “sports,” and “cinema.” When you select one of these modes, the brightness, contrast, and sharpness are automatically adjusted to preset values. calculate source rectangle (full subtitle bitmap) used when viewing half side by side anaglyph video that is stretched to full width NormalizedRect nRect = GetDestRectangle(width, height, subtitleLines) MFVideoNormalizedRect mfNRect = new MFVideoNormalizedRect() IntPtr hOld = SelectObject(memDC, hBitmap) ĪlphaBmp.paras = new MFVideoAlphaBitmapParams() Ī = MFVideoAlphaBitmapFlags.Alpha | MFVideoAlphaBitmapFlags.SrcColorKey | MFVideoAlphaBitmapFlags.DestRect IntPtr hBitmap = alphaBitmap.GetHbitmap() Graphics g = Graphics.FromImage(alphaBitmap) alphaBitmap is a 32bit semitransparent Bitmap
MFVideoAlphaBitmap alphaBmp = new MFVideoAlphaBitmap() But with GDI I cannot use 32bit alpha Bitmaps for true transparency - I only get 1 bit transparency with this approach: private void SetEVRMixerSettings(int width, int height, int subtitleLines) Now however the project MediaFoundation.NET doesnt have the alphaBmp.pDDS pointer to set, so I cannot use a directdraw surface and need to use GDI (IF SOMEONE HAS A METHOD TO DO THIS IT WOULD BE COOL). Hr = mixerBitmap.SetAlphaBitmap(ref alphaBmp) on unmanagedSurface the bitmap was drawn with transparencyĪlphaBmp.rDest = GetDestRectangle(width, height, lines) ĪlphaBmp.dwFilterMode = VMRMixerPrefs.BiLinearFiltering Set Alpha Bitmap Parameters for using a Direct3D surfaceĪlphaBmp.dwFlags = VMR9AlphaBitmapFlags.EntireDDS | VMR9AlphaBitmapFlags.FilterMode I used this to apply a 32bit alpha bitmap onto VMR9, using a DirectX surface: private void SetVRM9MixerSettings(int width, int height, int lines) Try to see what i'm talking about - you must set the EVR in options. I have subtitle overlay problems with the EVR: I implemented the EVR renderer into a player of mine to deal with bad resizing quality on Windows Vista+ and came to problems.
