Why does psy-rd do? What's its purpose?

Psycho-visual Rate Distortion tweaks. Quality optimizations based on psycho-visual models of image recognition, trying to suppress hardly recognizable elements of the video to save bitrate.

When i load up a d2v file to create avs script, MeGUI automatically sets input DAR to ( ITU 4:3 NTSC ). Am i supposed to change this to the normal 4:3?

Depends on your material. What was your source, an NTSC DVD? Does it show a TV broadcast or a cinematic movie? Can you spot soft borders of 8-10 pixels width at the left and right? Is there any scene where you can see an exact sphere to measure width and height?

The ITU aspect ratio presets are based on TV broadcast values where the interesting part belongs to 702 pixels inside the width of 720 pixels on DVDs. If you don't spot any hints of a TV source, then the generic aspect ratio is possibly "more exact". But only a visible sphere (e.g. the moon) will make it certain.

Being the illiterate newb I am, I am probably doing something wrong, but... do I need anything specific in order to encode DTS audio into mp3? MeGui says preprocessing for like 40 mins now and nothing happens.

edit: trying to click abort only makes the button grey out. Lame process is running in the background (zero CPU) and I can't even close MeGui (which is not frozen though) - it remains in process list, I have to kill it manually.

Psy-rd doesn't save bitrate - actually I believe psy-rd usually leads to a very slightly bigger file size. Psy-rd is to make the encoded video "seem better" to humans by applying some tricks through some kind of dithering algorithm and actually ADDING noise in a patterned manner in order to make something "seem" as complex and textured as the original (but not accurately).

I personally don't agree with the algorithm technique and so I turn it off with "--psy-rd 0:0". It seems to me that psy-rd just adds "noise" to make a face seem textured for example - but I would prefer my video to be as accurate to the original as possible and not have added random noise to make things "seem" as textured as the original. If you value as close as possible exact reproduction of the original textures - then I recommend turning it off with "--psy-rd 0:0".

I nailed it down to mp3 encoding problem. When I select flac it instantly starts. No idea what the problem is.


I have no idea what "preferred decoder" mean btw. Could someone explain?

It supports several different decoder filters for AviSynth; they may have advantages or disadvantages, may support specific source formats better or worse. Choose the one you prefer ... but at least one which works.

NicAudio supports AC3, DTS, MPA and LPCM sources.

BassAudio supports AAC sources.

FFAudioSource supports what FFMS2 has compiled into, but probably only/better as audio streams in multiplexed media files.

DirectShow support depends on the filters you installed into your system.

If in both cases the same decoder is used it must be the pre-processing like normalize. Please post the log file so that we can have a look.

Guess it was false alarm. I probably had the wrong decoder selected. After switching to NicAudio it started to work.

I'm using AVS Cutter, and make transition to fade.
Code:
AVIFileSource("E:\Project\360p-AE-Ut.avi")
__film = last
__t0 = __film.trim(119, 495)
__t1 = __film.trim(1029, 1231)
FadeOut0(__t0, 50,AudioRate(__film)) ++ FadeIn0(__t1, 50, AudioRate(__film))
Note: My real cut list is far longer than the above sample.

But result is the fade color becoming green instead of black.
In the script, instead of color, AVS Cutter is replacing color syntax with this clip properties?
Code:
AudioRate(__film)
I read on wiki, the variable was
Code:
FadeOut0(clip clip, int num_frames, int color, float fps)
If i add color=$000000, after num_frames, it gives me "argument color was passed more than once" error.

If i deleted the Audiorate, the fade were indeed become black.
But what is AudioRate actually do ?
Code:
on wiki : AudioRate;Returns the sample rate of the audio of the clip (type int).
I don't understand this.
Is it safe for me to delete the AudioRate, generated by AVSCutter? Or will this mess-up my audio?

If it's safe to delete that, how can i change the default template for AVS cutter, to not including the AudioRate ?
Because i have 100+ video i must cut and fade, i want to avoid manually editing/deleting AudioRate in 100+ script.

I got a negative aspect ratio error after cropping and resizing in MeGUI, is that ok?

I have a quick question and would apppreciate anybody's help.

Whenever I encode a normal standard definition 720x480 MPG file, no crop or anything, the AR always seems to be slightly off because the result always seems to come out a bit stretched compared to the source file. How do I fix this? Will selecting a AR manually in AviSynth fix this problem?

Thanks for the response, and quick one.

I want to keep it 720x480 so it matches the rest of the videos that i've encoded in the past of this series. Is it possible to do so?
Also, by cropping it, it reduced my 2pass encoding from 159fps/91fps to 104fps/85fps. sigh -_-

You don't need the black borders, crop them off.

Also, if ya don't mind me throwing out another concern for anybody to answer/help.

I'm using OneClick profile and I dragged 3 MPEGs to convert, and after confirming that I wanted to process the 3 files, as well as after cancelling the 2nd box that I didn't want to rename the files, it came up with a 3rd box that says something like, "duplicate subtitle tracks found do you wish to continue?". thing is I don't have any subtitle tracks or anything.

What gives?

I used to crop them a long time ago, but the end result is the encode always comes out much uglier, since, by cropping it, it allows more 'space' for the resizing.

I hope you know what I mean, but maybe it doesn't make much sense if I can't explain it well.

Also, I never found a good deinterlacer for this particular line of videos so it further crapifies what is already crap.

If you don't mind helping I could upload a clip, or if anyone wants to help then they can help, too

No, cropping does not worsen you encode. Use QTGMC for deinterlacing. http://forum.doom9.org/showthread.php?t=156028
