MovieSaver

The movie saver class is used for reading and writing movie streams. Has to be created with Alloc() and destroyed with Free().

Could you elaborate on "Reading"? I cannot figure out how to read an arbitrary frame of the movie?

I would use the Bitmap load but it does not seem to support alpha channels.

Sorry, MovieSaver is not for reading. The documentation is wrong. BaseBitmap can read movies with alpha channels, at least this code could:

    
    
      Filename fn = GeGetStartupPath();  
      fn.FileSelect(FSTYPE_IMAGES, 0, &String("Please select a movie!"));
    
    
    
    
      AutoAlloc<BaseBitmap> bm;  
      Bool ismovie = FALSE;  
      bm->Init(fn, 42, &ismovie);
    
    
    
    
      ShowBitmap(bm);

I tested it with a movie I saved from C4D with the Animation codec. The alpha is visible in the shown bitmap, and BaseBitmap::GetAlphaPixel() returned the expected value.
