I have used a png image in a video and added a fade out in VSE using the Gamma Cross. I just have another audio layer in the video. See attached images. I am using Blender-Render engine.

Render Settings

Encoding Settings

I am attaching three images sequentially fading out. You will notice that towards the fade out end the image starts to pixelate. Why does that happen?

See image state while fading out:

Sate1

Sate2

Sate3

The image has been created in Gimp with following

Properties

Even on a 200% zoom it does not pixelate.

What should I be doing to avoid the same?

Blend File as requested:

I can seem to download the blend file. see screenshot

The "Lossless" setting is a variable bitrate value. When the image looses information during a fade to black the bit rate drops. Change the Output quality to "Constant Bitrate". Place a high value, that retains the quality that you want.
