I am using AVAssetWriterInputPixelBufferAdaptor to create a video from an array of UIImage’s,
and i want to change the transition from one image to another in different forms of animations(much like a slide show … actually exactly like a slideshow).

One of these transitional styles is fade out.
since im writing UIImages like so ..

    UIImage *image = imageView.image;
    UIImage *resizedImage = [ICVideoViewController imageWithImage:image scaledToSize:CGSizeMake(640, 480)];
    CGImageRef img = [resizedImage CGImage];
    CVPixelBufferRef buffer = [ICVideoViewController pixelBufferFromCGImage:img size:CGSizeMake(640, 480)];

    [adaptor appendPixelBuffer:buffer withPresentationTime:CMTimeMake(i, 1)];

I would like to know if it is possible (without having to manually manipulate the pixels)
to achieve this .. ?
