FFmpeg: QuEnc 0.45 and KDVD

[Zyphon]

Hi guys, sorry if this has been brought up before but I am curious.

Can Nic's QuEnc 0.45 be used to make KDVD or is it really only useful for KVCD and SKVCD format?

To my understanding this encoder has probs with with GOP's over 18 is this still the case.

Thanks in advance.

Edit: My source is PAL DVD 720 x 576.

Sure you can
Just select the notch matrix, and encode as MPEG-2 with a GOP of 15(PAL) or 18(NTSC).

If you're doing a DVD(KDVD), you must use the GOP sizes above.

Thanks for the info Karl, I have a problem though when I try to do a KDVD using the res 720 x 576 and the MA Script I get this error when testing the AVS Script:

Avisynth: caught an access violation at 0x1000f3e0.
attempting to write to 0x069cfd80.

I used MovieStacker and Destination output as DVD @ 720 x576.

I copied the GripCrop params from MS and put them into the MA script and I get this error;

Here is my script its a 30 intro to one of my DVD's.

I used this for a test and like i say it worked fine for SKVCD @ 480 x 576.

Also if I used a GOP of 25 for KVCD or SKVCD would this not work in QuEnc.

The quality is pretty good in this encoder btw.

This is really strange the MA Script works fine if i do a SKVCD res 480 x 576 but it doesnt work on DVD res.

Do I need to remove the GripCrop line and replace it with something else?

Im really confused now.

strange,
i did toy story 1 & 2 using MA script as DVD @ 720 x 480 (NTSC)
a few days in QuEnc 045 without problems !

Thanks for your reply jorel, I loaded my d2v file into the new MovieStacker and loaded the MA filter preset and set my output res to 720 x 576 and it seems to be working.

The only problem though is that it seems slow going the process is only moving at 0.64 fps. Im encodin it on my Pent 3 @866Mhz is that the problem for the slow encode?

EDIT: In the Bitrate (kbps) Box do I need to calculate the bitrate if doing multipal films and should I use Calcumatic to get the bitrate value for this?

[jorel]

at 0.64 fps is not so slow for your Pent 3 @866Mhz, seems ok!

i don't used CalcuMatic for toy story 1 & 2 !
the size with the 2 encodes with one origina 5.1 audio channel for each encode,
give me less final size than one dvd-r can get !
..round 3.9GB in total!
i have full quality of audio and video with 2 movies in 1 dvd-r!

[Zyphon]

Thanks for your answer jorel.

So do I leave QuEnc bitrate box at its default setting?

[jorel]

yes, all default with kvcd notch matrix and chhose the right aspect radio!

Hi jorel, I ripped a section from my Autin Powers 3 DVD. It was the Music Video of Dr. Evil singing "Hard Knock Life", I used this as its only about 2 minutes and I knew it wouldnt take all night to encode. I just wanted to see the quality.

To be honest I wasnt impressed with the final result it looked pretty aweful and glitchy. I wish I had some webspace to upload the sample to for you to see.

I think I will have to stick with CCE for now as that produces the best results for me in KDVD and see what result that gives me.

Aspect ratio used was 4:3.

[jorel]

like i told you i did only that 2 carttons using the MA script without
STMedianFilter(3, 3, 1, 1 )
and with
ConvertToYUY2()
in the final of the script!

and in QuEnc was adjusted:
kvcd notch matrix (in advanced options),
mpeg2,
2500 Bitrate(Kbps),
use VBR,
High Quality and
2 pass encoding!

aspect radio 4:3 for toy story 1 and aspect radio 16:9 for toy story 2!
the video encoded was muxed with the audio 5.1 from source.

for that cartoons the result is amazing!
i never did using differents sources or movies!
if your adjusts are like i posted,
try a sample encreasing the value of "Bitrate (Kbps)" in QuEnc
to test if you get better quality!

The problem with QuEnc is that the internal configutarion cannot be touched, so we can't optimize quality. As oposed to mencoder and ffmpeg, where you have tons of configuration optios, so they can be tweaked to get the best quality possible.

Hi,
Yes for sure MEncoder is an option
Try VMesquita's Mencode-ME as it is a GUI/Wrapper for MEncoder.
And please be aware that we are not responsible if the final encoded video stream is done much faster than with TMPGEnc/CCE and that it may look better than those two
Cheers
