MeGUI: General Questions and Troubleshooting Thread - Page 441

YadifMod doesn't de-interlace itself. It needs to take the required pixels from an interlaced version of the clip. ie

A = last
B = A.QTGMC()
Yadifmod(mode=1, edeint=B)

YadifMod2 is Yadif and YadifMod combined. If you don't specify a clip for edeint, it de-interlaces itself.

YadifMod & YadifMod2 have a "Field" option for specifying the field to keep in "same rate" de interlacing mode. For Yadif I think it's always the same as "Order".

I kind of remember additional colorspace and high bitdepth support for YadifMod2, but the help file will tell you.

MeGUI uses YadifMod2 instead of Yadif these days.

It should be in the MeGUI\tools\qaac folder. You'll probably need to enable it in preferences (there should then be a QAAC option in the list of audio encoders). It needs some Apple files, which do the actual encoding, so you'll need to download the Apple iTunes installer. You don't need to install it.
http://www.apple.com/itunes/download/

I think you have to install 7-zip
https://www.7-zip.org/download.html

Put the iTunes installer in the MeGUI\tools\qaac folder and run makeportable.cmd. It'll extract the required files. You can then delete the installer.

Its builtin to MegUI already as one of the optional audio encoders (ie change the selected encoder).

EDIT: Hello_Hello said it better.

imsrk48,

The provided script is probably not the best ever script, if you do intend to pursue, then post in avisynth forum where the experts can give better scripts.
in particular, the line

Code:

MASK=I.BlankClip(Color_YUV=$FF8080)                                                     # Solid White (just dummy for ApplyRange really)

Could probably be better, as should be full PC levels white, whereas I think above line will produce TV levels white.

Elliptical Logo Demo (req Masktools v2)

Code:

# Requires Masktools v2

Function OverlayClip(clip c,clip c2,Int "S", Int "E", Int "X", Int "Y",Float "Opacity",String "Mode") {
/*
    Requires RGB32 clips c and c2, c2 with Alpha mask.
    Overlay clip c with clip c2 using c2's RGB32 Alpha channel mask, frames S to E, @ clip c overlay coords X and Y.
    Start and End Args S & E, are similar but not exactly like trim.

    OverlayClip(c,c2, 0,0)     # Entire clip
    OverlayClip(c,c2, 100,0)   # Frame 100 to End of Clip
    OverlayClip(c,c2, 0,-1)    # Frame 0 Only
    OverlayClip(c,c2, 1,1)     # Frame 1 Only
    OverlayClip(c,c2, 1,-1)    # Frame 1 Only
    OverlayClip(c,c2, 1)       # Frame 1 Only [Not same as Trim()], E defaults to -1 ie single frame.
    OverlayClip(c,c2, 1,-3)    # Frames 1 to 3 (ie 3 frames)
    OverlayClip(c,c2, 100,200) # Frames 100 to 200
    OverlayClip(c,c2, 100,-50) # Frames 100 to 149 ie 50 frames

    X and Y are OverLay x & y offsets, and can be -ve where is relative to c.Width & c.Height, use eg x = -(c2.Width+16)
    If c2.Framecount is shorter than S,E specified range, then final c2 frame will be used for remainder of overlay range,
    so if c2 clip is single frame, then that frame will be used for entire overlay range.

Hello. I'm wanting to upmix 72 2.0 audio files to 5.1 using the "SuperEQ" option in the audio configuration settings, and I'm wondering if it's possible to batch load the files or if I have to load them individually. Ahhh, also, if anyone knows of an improved method of upmixing I'd be happy to read of it. Thanks for any help

How to Use FFmpegSource for Encoding Instead of Windows Default Encoders?

LigH · 25th April 2019, 09:09

@imsrk48 - do you possibly confuse encoders with decoders?

MeGUI offers you FFMS2 (or L-SMASH Works, alternatively) per default in its "File Indexer" during the source selection. DirectShow decoding is disabled in recent versions, you would have to enable it manually.
_

@LouieChuckyMerry: No guarantee, but batch audio processing with AviSynth base might be the domain of BeHappy, instead of MeGUI.

I don't know Sir. I have tried ConvertToYV12 but after this encoding speed is too slow showing 40 minutes in first video pass.

Please Suggest me best method. I bag You.

Really urgent Sir.

I want to encode a video. Really urgent or important.

StainlessS · 25th April 2019, 21:03

So far as I know, MeGUI REQUIRES YV12 final colorspace to work at all, and if already in YV12, then ConvertToYV12 does nothing.
So, dont have a clue as to why encoding speed may be slow.

Quote:

When the target format is the same as the source format, the original clip will be returned unchanged, except for the case of ConvertToYV12 where the ChromaInPlacement and ChromaOutPlacement parameters are different

http://avisynth.nl/index.php/Convert

Again, suggest that you learn at least basic Avisynth scripting, then you might have more idea what is wrong when problems show up.
If you add eg

Code:

# some script stuff
...

#ConvertToYV12  # comment out for showing info, then remove when not showing info
Info

And set in options to "Show video preview after avisynth script selection", and see what Info shows you.
What is the colorspace shown by info ?

Video Colorspace is RGB32.

StainlessS · 26th April 2019, 10:36

I'm using a slightly older MeGUI (dont have any installed currently), but it always used to ask if it should add "ConvertToYV12" at end of script when not already YV12
(maybe other planar YUV worked, not sure).
Have no idea why RGB32 should encode faster than YV12, seems a bit crazy.
Maybe someone else has an idea what it does, why it is faster when RGB32.

sneaker_ger · 26th April 2019, 10:40

Is it faster? It didn't work at all for him. Maybe the speed he gets is totally normal.

LigH · 26th April 2019, 11:11

There are usually two groups of reasons why encoding feels "slow":

a) a lot of slow video filters (to evaluate this, we need to know the complete AviSynth script)
b) the video encoder set up with a very slow parameter set

In any case, inspecting an MeGUI log file of a rather successful encoding attempt would be most appreciated. Begging does not accelerate our help. Facts may do.

Encoding Speed too Much slow when Input Video Have RGB32.

EDIT: OK, think I figured it out, you maybe are using script in post #8808,which requires RGB32, and uses Overlay.
I'll mod the script for YV12.

But repost your log.

Thank you for your answer. I tried BeHappy some years ago and found it well above my head, but I'll try again. Maybe I've actually learned something(s) since then ;-) .

It needs to take the required pixels from an interlaced version of the clip. ie A = last B = A.QTGMC() Yadifmod(mode=1, edeint=B) YadifMod2 is Yadif and YadifMod combined. If you don't specify a clip for edeint, it de-interlaces itself. YadifMod & YadifMod2 have a "Field" option for specifying the field to keep in "same rate" de interlacing mode. For Yadif I think it's always the same as "Order". I kind of remember additional colorspace and high bitdepth support for YadifMod2, but the help file will tell you. MeGUI uses YadifMod2 instead of Yadif these days.
