Hi jorel,

I think I know what you mean. It's the extremely high chroma values that are applied on very low movement scenes. I'm fixing that right now

Thanks for all of you with eagle eyes out there

I was able to see the effect CLEARLY on a specific scene on K-Pax. Here's the fix:

Code:

ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf > 2 ? \ 
unfilter( -(fmin(round((nf/0.5)), 100)), -(fmin(round((nf/0.5)), 100)) ) : \ 
TemporalSoften(4, round(1/nf) , round(3/nf) ,0, 2) ")

The previous values were just plain too strong

There shouldn't be any "Bleeding" of chroma now. Period

I'm updating the script page right now.

What now, are we in trouble again

good thing i hanen't encode enything yet.

kwag · #45 06-29-2003, 07:23 PM

Don't worry, we nailed this one in less than 24 hours

yes dear friend, right between the eyes.

really better(my opinion)

and when i load the script in vdubmob it run soft,
the system runs easy too and the image is cool without "breath"

the best...the prediction CQ encrease 3 points.

@ Osvaldo,
i did a encode when i see it and have to do all again.
i have 9

movies to encode, my 2 hds are full of vobs.(100Gb)

Hey Kwag TemporalCleaner sims to do a good job

TemporalCleaner (ythresh=5, cthresh=10)
Im becoming a filter frik now

That's exactly how I found the problem. It looked really nasty on a scene in Vdub, where the person sits down and the camera stays still. So it's a vertical scroll. So I tunned the values until the effect was gone, and then I lowered it about 10% for insurance

Same here

everything is better!

more CQ, more image quality, the system run soft and faster too.

big goal Kwag

LOLROTF

Just finished encoding K-Pax with the script update.
I used ToK and "Fast" prediction, for a CQ of 64.18

Wanted video file size by MovieStacker: 714,303.19KB
Encoded file size: 714,352KB

I don't think we need to calculate the % precision this time

Wha

Man I hope my results are as good as yours. I'm going to try out the new script right now. Kwag you still using ToK 0.0.5.2?

Kwag,
see my results and if i'm using the right adjusts in ToK

CQs predictions from ToK0052 with the new script!

using 1st group of passes:
precidion% 0,50
speed up by 1 time

CQ: 59,639

and using new faster prediction (Tenra)

CQ: 59,638

right?
you only check the (Tenra) to got your results

kwag · #54 06-30-2003, 01:40 AM

Hi jorel,

Yes, I only check "New Faster Prediction", set Precision to 0.5% and Speed Up by 10.
For full prediction, I uncheck the faster prediction, and also uncheck the 2nd group of passes. Then I change the first group speed Up to 1.
For all, I leave the factor for prediction set to 1.0.

thanks...

testing all ways now!

kwag · #56 06-30-2003, 02:02 AM

Well what can I say

, here's a sample from the last encode

I think this just can't get any better ( at least for the next 48 hours

)
This looks almost like ( or like? ) my DVD

Comments always welcome

jorel · #57 06-30-2003, 02:23 AM

Kwag
i download the k-pax sample and see
good quality colors with great matizes, amazing sharpness too.

right as you wrote
"I think this just can't get any better ( at least for the next 48 hours

)"

for me too.

How is it possible that CQ goes up when you lower the filter values??

Probably because the values were going up so high, that the color bleed caused chroma/luma shifting and ghosting, and the image was actually dirtier

Now that the picture is extremely clean, the CQ goes up

Well I wasn't as luck. Came up 30MB short on a 800mb CD encode with the new script. Looks great though, so I'll settle for a little loss in space.

Kwag, are you using 1 sample per minute and the auto sample size for your prediction?
