[FFmpeg-user] Help Getting a higher quality windows-style format from an MP4

[Luke Davis]

Hello

First, I am no video guy, so there is a great deal I don't know about the 
terminology and best practices.  This is probably trivial for most of you.

I have a need to play an MP4 file on some very big screens, from a rather flaky 
Windows computer.

I am trying to convert the MP4 into something that doesn't require quicktime 
(I.E. more windows friendly).  I thought first of ASF, but am open to other 
options.

Source MP4 (extract from youtube, using youtube-dl -f best):
https://www.dropbox.com/s/vk3qglmfgizgajg/There%20She%20Stands%20-%20Michael%20W.%20Smith-i2hvouzjswo.mp4

First attempt:
ffmpeg -i file.mp4 file.asf

That works fine, but the quality frankly sucks.

Result: 
https://www.dropbox.com/s/y2bvbbcdgdu4bj0/There%20She%20Stands%20-%20Michael%20W.%20Smith_non-quicktime.asf

Pixilation, etc..  I next tried this:

ffmpeg -i file.mp4 -an -b 2020 file.asf

Result: 
https://www.dropbox.com/s/z9k2vqulc52i3wd/There%20She%20Stands%20-%20Michael%20W.%20Smith%20%28Windows%20version%29.asf

(I don't care about audio)

What can I do to improve the quality of this process?

Thank you.

Luke
