Kwag,
 

Testing YMPEG with 16:9 DVD to 720x480 KDVD using Optimal MA script. With TEMPGEnc, I use 16:9, Full screen (keep aspect ratio), fast motion.

:?: How do I maintain aspect ratio when using YMPEG and what settings should I use on YMPEG setup screen for DVD output?

:?: Also, what settings should I use for minimum, average and maximum?

Re: Kwag,
 

The same way you set aspect in your .avs script :!:
Use MovieStacker. YMPEG will maintain the proper aspect via AviSynth.I get constant core dumps when I change MIN, MAX, AVG. Apparently, these options are still very alpha.

And BTW:
*** YMPEG now has initial support built-in for KVCD *** :ole:

Let's give a big grand applause to to yusuf :D

:?: How do you access this? I've downloaded latest version.

Check the "KVCD" option box :!:

Well the Codec still seems to be corrupt...

I get the same error message you do kwag, after it encoded 10kb... :(

I noticed that for VDub I had to use fast recompress along with disabling the input and output video, this way I don't get the error after the first few frames.

@yusuf,

I'm getting:
An out-of-bounds memory access (access violation) occurred in module 'ympg'. most of the times :cry:

I also get this some times:

Hope this helps in debugging :!:

This is with version .65
But hey, it's Alpha version, so all bugs and glitches are allowed :mrgreen:

Have somebody tried to use YMPEG as external codec in TMPG?
Or maybe VDubMod?

I have tried it. :D
The good thing is you can see the preview and TMPG counting the frames. As for the errors I have it here plenty. In fact this was only one error repeated many times:"Read error occurred at address 0191F456 of module 'ympg.dll' with 00000000"
Script
Avisource("C:\Video\Scripts\Test.avi", false)
GripCrop(X,Y)
Gripsize()
GripBorders()

Clip has 7026 frames
544x576 KVCD MPEG-1
Bitrate 300, 1000, 2300 Kbps
VBV 40, I interval 15, P - 3 (here I simply forgot to change it :oops: )
MQuant 8 Best Quality
The error occur at frame 5160.

Low quality, I:24, P:3
Again at frame 5160

480x576 Best Quality
Again at frame 5160

352x576 - at frame 6840, 352x288 - at frame 192

Change the bitrate 100, 1000, 2500
352x288 - no error! Clip was encoded.
352x576 - at frame 6840
480x576 - at frame 6000.
Hope it will help for further development.

Closely investigating the GOP structure I found in the break region defects in the gop similar to:
PBBPBBPBBPBBBBPBBPBBPP-BREAK

Just tested version 0.6.6:
"An out-of-bounds memory access (access violation) occurred in module "'ympgcdc'.
On every try :(

And again.

Can I change the quantizie Matrix and how is the codesc.

How do I view the output file,I end up with a small avi that wont play in wmp,vlc,etc and a .vid file.What do I do with them to make them an m1v file?

Rename this file to *.m1v or m2v. :wink:

I managed to encode whole movie with the YMPEG frameserving with TMPGEnc. The quality was not good, because the codec didn't keep the average bitrate. My settings were min 0, avg 1100, max 2500. VDubMod show that the average of the encoded file is 780 Kbps. After few more tests I found out that in fact the average bitrate depend solely of the setting MQuant - lower the value higher the average. It seems to me very similar to the quants in DivX encoding. The problem is that it is integer only.

Version 0.6.8 bug reports
 

An integer division by zero occurred in module 'ympg'...
...while compressing frame 3 from 063cc800 to 00c4e3f0 (VideoSequenceCompressor.cpp:392)...
...while running thread "Processing" (thread.cpp:120).

Hi, I install YMPEG 0.6.8 alpha and shows in my video codecs control panel on windows but doesnt show on virtualdub ???, I tried several times but no luck ??

Hi cable_loco,

You have to select "Full processing mode" in Vdub, and then you'll see the CODEC when you select "Compression..." in the Video menu option.

Audio & Aspect ratio
 

im pretty confused here,

i hearing about YMpeg rite and it sounds promising but how can i keep the aspect ratio using an avi synth script but still using the audio thru YMPEG cuz i am using an avi i file and if i get rid of the nifty ",false" part at the end of my file path in the avi synth script then i get the good ol ACM failed to suggest a compatable PCM format error.
so how will i be able to keep the aspect ratio but still encoding the audio thru YMPEG?


I Figured i could get around the problem by doing the video and audio sepratly, but could i get YMPEG audio codec into Besweet or something?

(another quick edit) When i try to strip the audio from the avi to a wav like normally the compression option is greyed out, im following the instructions on the site, is that obselete now?? Should i do the normal file>Save Wav, thing and then in audio select the wav file i striped into virtual dub will that help?

@yusuf,

Hope you read this :!:
0.6.9 is looking much better :D
I think you hit the memory leaks right on the nail :!:
However, there's a problem with "B" frames.
The encodes look jumpy, with either 1 or 2 B frames.
If I encode IP structure only, everything is fine, but of course at a quality loss.
Keep it up, this is looking good :)
