Not encoding above 500k

[techz]

I cut a 40 sec d2v file out of a futurama ep and just wanted to see what it would look like @500k and @900k, but for some reason gknot wont go above 500k, i disabled audio to save time and even tried xvid but it just doesnt go above 500k. I know the comp check is off the scale, 150% or something,but even when i do or dont do the comp check it doesnt budge over the 500k bitrate mark.
PLZ HELP :confused:

The final file after this job is only 470k video bitrate

Hi-

Use a higher resolution. You're maxing out the quality, size, and bitrate at that resolution, and DivX is unable to use over 500.

So at thar res, i cant get any better quality, never had that prob before :) Thanks I thought thats what it was


by increasing the res, and the bitrate, would the total effect be the same, because the b/pixel arent changin only the no of pixels and bit rate are,

e.g @320x340 and 500k i get .300 b/p
@384x288 and 700k i get .300 b/p

the effect is the same ?

i'll teat them but i wanted to get ur input

I'm not sure what exacty you are asking with "the effect is the same?", but I've the feeling your comparing apples with pears. If you have two different sources, there is not much use comparing only the bits/(pixels * Frame). That measurement only tells you how well a clip can compress.

To make it more clear for you. After doing a compressability check, GKnot lists two bits/(pixels * Frame) values:
1) The value for your current GKnot settings dependent of choosen resolution and bitrate (above LOAD button).
2) The maximum value possible ever (a bit right of the LOAD button.

The compressability check is derived from this by:
current/max * 100%.

e.g. if current is 0.300 and max is 0.500, the compressability check is:
0.300/0.500 * 100% = 60%.


I know the comp check is off the scale, 150% or something,but even when i do or dont do the comp check it doesnt budge over the 500k

You gave your own answer ;) In this case current is more than max and obviously the best you will ever get is max. A compressability check is OPTIONAL (though highly recommended). If you don't do a compressability check, it does only mean that you don't know:
1) If your quality will be any good (between 60% and 80%).
2) Your final result will be undersized (as happens if comp test tells you the result is above 100%).

Looking at your low resolutions, I assume you are working with captured sources?

no just futurama dvd's 320x240 is good for 1.33 AR plus i noticed that alot of people use that for animation. anyway i tried it out and both results , 320x240 and 382x288 gave me the same result, only the latter had a bigger file size for the quality of 320x240.

[piscator]

If you take 640x480 it's also good for 1.33AR, so I'm missing your point.

And no, 320x240 and 384x288 don't have the same quality. Higher resolution is better quality! And of course the filesize is bigger (you're going undersized) as soon as you increase the resolution, so no suprise there :confused:!

thanks a bunch, i really messed up, the higher res gives better results, :bowing down: :thanks:
