KVCD: Higher cq value or higher maximum bitrate?
 
a question to all those kvcd experts out there :wink:

i have a 90 min file, file prediction tells me, i can use cq 66 , if the max bitrate is 2500 and min bitrate 300 (standard settings)

will i get a better result , if i lower the max bitrate to eg. 1200 and set the cq value to 100??

Hi Kane,

Let me extend your question for these guys. If I have the same 90 min file, which is the best results: to make it with a low resolution (320x240) with high CQ number, or make it with a better resolution (528x480) but with a lower CQ number?

Not if it's a high action movie.

ahh, so, for a high action movie high max bitrate is better
Thx

I'm not even doing 352x240 anymore with the new filters. 320x240 is out of the question. That's way lower than standard VCD resolution. For regular ~2 hour action films, I put everything on one CD at 528x480 with FaeryDust and TemporalCleaner. Longer than that, I encode for two CD's with SpaceDust and TemporalCleaner :wink:

hi kwag...

do you have a sample of a ~120 min. movie that you DID put on one CD with these settings? I just wanna make sure that my encodes still look like they are supposed to look... :wink:

Here's one:
http://www.kvcd.net/redplanet-cq78-faery-c3d.mpg which is close to 2 hours.
There are many more samples scattered here: http://www.kvcd.net/forum/viewtopic.php?t=2339
