And now you should see clearly a MUCH better quality on the walls :!:
The encoder was not optimized, because it was encoding with an erroneous VBV buffer size. So now look at the DCT blocks on the walls, and I'm sure they are equal (if not better?) that CCE ;)

-kwag

:?: Where exactly on which screen is this?

:D And Kwag, you made my day with the screen examples!

Ok, Kwag but your way in the last pics with that field where you put 10 and when changing than would give filesize differencies, .. won't work for me.

But what works is when changing the Qauntisation values from 2 to 3 in the I P and B frame quantisation section ... and that makes sense?!

DAMN!!!! 8O

I gonna post Pics right in the next few minutes!!

:D :D :D :D :D :D :D :D :D :D :D :D :D :D :D :D

When rising the quantizer in that high bitrate to 3 as min in the I P and B franes its still veryyyyyyyyyyyyy ggoooooood and I got for a 98min movie in PAL! means more FPS and more pixels! about 8360kbit on a 1% moviesample = Prediction Goodbye!

I didn't compared with CCE now but :arrow: AWESOME! And my lower speed issue went away in CBR!

Just very below to the right just left hand to the little watch in the desctop

@Nicksteel,
You can find it on the "statistics" settings of ffvfw.
Just choose show tray/graph.
Hurry man. Go run some tests with it :wink:
C ya

323 kb image size jpeg quality 50% ----- who cares, lets kick da bandwith! :wink:

Ok, here are the samples at PAL 25 FPS 704x576 overscan=2

1% Sample Filesize: 8.360 kb! Watch the avg bitrate in Bitrateviewer at 704x576/25fps! And thats a 1.85:1 movie.
Movie length about 95 mins, let it be more who cares if it wont get over 1300mb á 3 Movies on one DVD-R non-anamorphic.

Here it comes, first Bitrateviewer followed by the jpeg Pic (Quality 50%!!)

NEXT Step will be full CVD compilant 352x576 mpeg2 one movie to one CD using Notch! incl. 128kbit audio ... lets see!

SWEEEEEEET Incredible :mrgreen:
:ole:
I'm with you 100%: Bye Bye file size prediction :rotf:

-kwag

Great Result, Inc.
With or without filters :?:
I have to find a DVD thats clean enough for this comparison. Xmen II is too noisy :roll:

My experiences with Karl's latest settings are similar.
The bitrate peaks go up to 6500 while average is ~2000. This is just great 8)

Here's the script I used:I used Also DCTfilterD(4) as the last values of the MA in the right korner below of the matrix won't get higher than 63! But on the other hand no merge/chroma/blur

@inc: Thanks for the info.

@Kwag:
Changing the min/max quant. doesn't change filesize or average bitrate for me. I'll do some further tests, but there wasn't any difference between 2, 3 and 10.

It has to 8O
For example, start with all values set to 2.
If file is too large, change them ALL to 3. Etc, etc.
The higher the numbers, the lower the file size.
Works for me :!:

-kwag

Yep, you're right. I missed "All" :roll:
I thought that min would be a minimum and max a maximum. So you have to change both. Do you know why this makes sence :?:

@ Krassi
Quantisation means in ffvfw "Q" mode, means the quality, :arrow: the more you quantize the more the pic gets worse.

The max quantize Values of I P and B is just ignored by teh encoder, min Qantize is what counts, do look during encoding at the graph as I explained above and you can see that the quantizer while encoding stays almost constant at the min value you did set in the quantize options! And will be the same then in Bitrateviewer!

Now at 352x576 the encoder behaves a bit different!! and not that efficient Like at bigger image sizes!
I did lower the min quantizers back to the better value of 2! (I P B) but on the other hand I can go to 2510kbit CBR (= VBV 44) (lower values will let suffer the image! and we should keep in mind that 352x576 will be scaled 2xtimes in its with afterwards!)

Heres the report on 352x576 at still 15 GOP!: Final size on 1% sample is 6.164 incl. Audio would fit nice on one CDr80. Next step will be 480x576!

http://www.digitalfaq.com/archives/error.gif

Okay, got it now. Thanks.

@incredible:
will we need a different CBR kbps value for each resolution?. Do you advise 2510 for 352x576 res.

In my workout now its the mixture of min Qantize and the kbit value in CBR!

But till now I do not recommend nothing as these are my first successes and Im doing on 480x576 now.

I'll answer that.
*** NO ***
The CBR bitrate value controls the size of the VBV buffer size.
Leave the values that I posted on the procedure to make KVCDs or KDVDs.

Edit: Correction. You can actually go up to 48KB ( a VBV value of 24 for KVCDs and VCDs ) which should be optimal.

-kwag

Kwag! In my case it controls the VBV Buffer size AND the value of avg bitrate! And in my samples it makes sense as only adjusting the min quantizer wont give effective results as the baviour of resulting filesizes got a too wide range in just one step of quantize value :!:

Cross posting/editing :lol:

Strange! When doing 352x576 I could rise a bit the endsize/Quality by screwing at the CBR but now at 480x576 the final size is FIX!
