Saved video gives bad quality

[Thops_of_Kenya]

Hi
I rendered a video in 640x480 and 25 pics/sec at the 3rd quality level.
It took almost 4 hours [:)] but that's ok.

When i looked at it in S3D it looked great, so i saved it. [:)]
I looked at it in VLC and the quality was a disaster, not close to what i what i saw in S3D.
I tested Windows 10 media player, same thing.

What went wrong and how do i get the same quality from the saved video ( 123 Mb )

Did you try to compute one image with the same quality settings to check if it would be better?
