KVCD: Low resolution source and KVCDx3?
Hey guys, I have some DivX files of Farscape episodes I've been trying to encode. The resolution on them is lower than most DVDrips and I find that if I use the KVCDx3 template the encoding time is more than double what a higher resolution source would take. My guess is because I'm going from a lower res (432x320) to a higher one (528x480). Could I save encoding time by changing the KVCDx3 resolution, and if so which ones should I try?

Hi J-Wo,
Go for KVCD 352x480 PLUS template. :wink: -kwag |
Thanks Kwag! For some reason it's taking me 3 hrs to encode only a 45 min episode using the KVCD+ template, but it is an improvement of 4 hrs with KVCDx3. I don't know why these Farscape episodes are taking so long to encode...
But here's something else weird. I noticed these DivX files had a bit of noise, especially in dark scenes. So I tested ten different filter combinations on a small 30sec clip, and finally decided on using Code:

Comparing 528x480 KVCDx3 to 352x480 KVCD+, there's a slight reduction in noise and the image looks slightly sharper with KVCDx3 (but again, that's if I scrutinize by sticking my nose up to my TV. I shouldn't notice it that much when I sit back on my couch). But the sacrifice I make is encoding time. It only takes ~2hrs using KVCD+ but ~3hrs with KVCDx3. Are there other encoding resolutions worth trying? And is the only difference between these two templates their output resolutions? |

I use KVCDx3 528x480 99% of the times, and if I still want a movie on one CD, and the result at 528x480 is just not good enough, then I go for 352x480 PLUS template. The only difference between KVCDx3 and KVCD 352x480 PLUS is the resolution. All other parameters are exactly the same. Even the MIN and MAX bit rates. If I can't get acceptable quality on one CD at 352x480 looking at my prediction sample, then I go back to KVCDx3 528x480 and target for 2 CDs. -kwag |
