Oh yes.

What kind of content
are you encoding? Is your target VCD?


Take a look at http://www.ysrnry.co.uk/tvprog/ - it's mainly captures
of old computer games, so there's lots of sold blocks of colour, plus
lots of photos and the odd bit of animation. TMPGEnc produces visibly
smoother output with fewer artifacts.

Can anybody comment on *why* TMPGEnc produces higher quality
output?

From my uneducated POV, I notice that TMPGEnc MPEGs are ~10% larger 
than MPEGs encoded using other tools. I guess that means it stores
extra detail, and that bumps up the display quality.

If anyone can come up with a set of Transcode options that matches or
beats TMPGEnc then that would be incredibly useful to me. Meanwhile,
can anyone suggest how to switch off this "RIFF chunking" business
that's currently throwing TMPGEnc?

Ta,

Nick
