It looks like you selected the deinterlace checkbox while megui was running the analysis, bad idea to change settings while it's working.

fixed in the next build.

Can someone tell me why the video is streched when it finds 16:9 format? I mean the picture doesn't fit and looks like crap.

after selecting an avisynth script. In the encoding process it too pops up. It is so annoying. does anyone know a fix for this?

Edit: Here is a pic

after I click cancel it still pops up

Does someone know a solution for this?
Even a fresh installation of megui doesn't solve this.
I've tried everything.

Do you have virtual memory enabled? Mine was disabled and I was getting some crashes with megui. Now, I have enabled it and none till now.

Just FYI on interface problem in Vista 64. I know you don't support it, but I have lost Gui buttons in the past but was able to get around it. This one is a killer...

I lost the Avisynth save button before, but was about to work around. Have not had the Aspect ratio button either. Not sure why this is happening, just thought you should know. I went back to core 0.3.0.3004 to get the DV2 Creator fixed, so it was lost with a change since then.

Hello.

I ripped Transformer Blu-Ray and encoded it to 1080p no problem.

But then I decided I wanted it to be 720p to save some space on HD. I was too lazy to re rip the Blu-Ray, so I decided to use the 1080p source, but something very weird happened. Instead of desire 4000 bitrate, it came up with 300 average bitrate at end!

I used x264: Standalone-Blu-ray, the only thing I changed was the bitrate from 8000 to 4000.

I'm thinking that its x264 bug or what?

Thanks for help.

PS Just noticed there's new version of x264, will download it and try 1st pass of 2nd pass and see what's output's stats is.

Seraphic- · 11th January 2009, 21:38

In the Nero ACC configuration, is "improve accuracy using 32 bit & flow computations" recommended to be enabled or disabled?
Is turning it on or off based on the encoder configuration used and file input?
(I.E - LC vs HE and 128 kbit/s vs 256 kbit/s or 16bps vs 24bps with 44.1kHz vs 48kHz).
Or should it remain enabled regardless? Thanks.

SacredCultivator · 12th January 2009, 08:23

Hmm for some reason when I encode audio to .mp4 using FAAC, the audio comes out very "static-y/noisey", in the past this never happened, and now I am useing Nero as the alternative.

Anyone know why this happens? And when using the Nero encoder, how does the VBR work? As it is b decimal, ex. .5, if on the FAAC I used 90, would that be equivalent to .9? NOt too sure.

Thanks.

OH MY GOODNESS.

It was ArcSoft TotalMedia Theater's fault!!! I was using it to watch my ripped Blu-Ray, but it wasn't until 3 or 4 days after I started to using MeGUI again. Look like ArcSoft's codec was having some conflict with ffdshow. After uninstalling ArcSoft program, the bitrate came out right!

Downside, I probably would have to find new Blu-Ray player on my computer.

Hope this help some people out there.

Sorry, I can't reproduce your problem (v0.3.1.1009).
BTW, NeroAacEnc is now better encoder than Faac, use always Nero.

Nope.
I recommend you use this ranges:
<.31 -> to play with low quality audio equipment.
.31-.35 ->to transcode ac3/dts with minimal lose of quality
.36-.5 ->to compress lossless sources, good quality
>.5 ->to compress lossless sources until insane quality

SacredCultivator · 12th January 2009, 16:23

^Thanks.

So then I don't know if it's comparable, but let's say if for .mp3 I use 128kbps (CBR) what would be the rough equivalent in VBR for nero? and same for if it were 192kbps?

Thanks again.

L.E. Actually the source is 3ch ac3!

Format : AC-3
Format/Info : Audio Coding 3
Codec ID : A_AC3
Duration : 1h 36mn
Bit rate mode : Constant
Bit rate : 640 Kbps
Channel(s) : 3 channels
Channel positions : L C R
Sampling rate : 48.0 KHz
_

L.E.2 any sugestions how to downmix 3ch to stereo?

Kurtnoise · 12th January 2009, 22:52

you can't do that with MeGUI...

Snowknight26 · 13th January 2009, 00:15

Selecting a FLAC track in the bitrate calculator causes a fatal error of Value cannot be null. Funny thing is though, it fills in the bitrate field because the mediainfo wrapper supports FLACs.

How about that DTS bitrate issue, too?

Please

There are many comparatives between audio codecs and in this thread is off topic.

Maybe 0.3 and 0.5

You can create an sample.avs file (using Notepad) with this line:

Code:

NicAc3Source("F:\x264\Vicky_Cristina_Barcelona_688p_ac3.ac3", 2).Normalize()

and open the sample.avs in MeGUI (Audio Input) instead the .ac3

NicAudio can downmix 3-6 channels to 2 channels internally.

b66pak · 13th January 2009, 19:42

@tebasuna51 thanks a lot...

@Kurtnoise13 handling exceptions and errors is a VERY important part of a program! if megui cant handle anything but 6ch>>2ch a warning must be done to prevent losing time and unwanted results...

Kurtnoise · 13th January 2009, 22:06

There are errors/exceptions handling. Just tell me why should I raise errors notify when all is fine...

tell me how you open flac files in bitrate calculator. This kind of file is not allowed. Embedded in Ogg container ?

Type * in the file name textbox, select .flac file. If it's not allowed, it shouldn't fill in the bitrate field afterwards.
