<div>since you mentioned video encoding guides , do you have any good ones</div>
<div>which you can publish here the links to?<br><br> </div>

bpp. :) But of course we both know that's a<br>> rough estimate and the requirement varies based on content. Consider<br>> it a guideline for 'an average DVD' as your source.<br><br>Woops, that's what I meant, yes! Bit per pixel is a pretty rough
<br>estimate as not only the quality you'll get depends on the source (if<br>it compresses well or not) but also on video resolution, i.e. lower<br>resolution need a respectively bigger bpp to look good than higher<br>resolution videos.
<br>Therefore, once you'd have read some video encoding guides, you should<br>just use bpp as a starting point to run a compression test, and then<br>adjust the bitrate accordingly.<br><br>Guillaume<br>--<br>Life is pleasant. Death is peaceful. It's the transition that's troublesome.
