Hi guys,

A few years ago, when Xvid hasn't reached the 1.0 version I've learned from the developpers that I should let "Xvid do it's magic" .

Meaning? Not capping the upper limit of quantizers, why ?

Because some scenes will look good with a higher quant and some won't look good with a 4 or even 3, if Xvid is capping the higher quants there might just not be space left for the lower quants and xvid is very smart at assigning bitrate where needed.

Let me put it this way, in a capped quant situation of lets say max 4 (I-frames), you won't get anything above 4 but also you will get much more q3 than q2 if you didn't cap (numbers...numbers) where you would probably get q5 and q6 but much more q2, visually on the scenes where you get q5 and q6 you would hardly notice any difference to q4, but with the lower quants the situation would probably be different.

Just my beggining of the day 5 cents.

All the best,

Sharro
