MeGUI: General Questions and Troubleshooting Thread

[Sharktooth]

I have noticed the same problem.

Doesn't adaptive quantization only improve the quality in dark scenes? 40% bigger filesize is a big price to pay for a little better dark scenes. Plus, I think is should be --aq-strength 0.
no. the new AQ (Variance AQ) improves quality of almost every frame.

[weaver4]

@weaver4
Therefore You need to raise CRF. 1280x720 with CRF22+AQ will give you something around 6Mbps (12Mbps for FullHD) In my opinion result is better than 20 without AQ. You may also try AQ with automatic sensitivity and your file size will be even smaller than without AQ :) --aq-strength 1 --aq-sensitivity 0 (0=auto)

I did not see anyplace in RipBot's codec's settings to set --aq-sensitivity to 0.

I did not see anyplace in RipBot's codec's settings to set --aq-sensitivity to 0.

But this is MeGUI thread :)

[montyny]

Hello,
I made one conversion using megui without any problems (a DV .avi file). However, trying to convert an avi from a VHS capture is a different story.

I realise now that the avi file has about 6 seconds of blank input at the start. The video conversion ignores this 6 seconds and avisynth starts at the first real video frame. However, the audio starts and has the 6 second delay.

With the given input file, how can I get the video and audio to be in sync?

Thanks - Bryan.

Hi montyny,

I am afraid, this might be the very wrong thread for that, but anyway, I would open up the dv.avi in virtualdubmod and simply mark and cut out the 6 seconds of nothing before I'd go on searching for reasons for the strangeness.. Simplay Save your now trimmed file and you should be set. Good luck!

Oh well... i re encoded an .mkv video file to h264 .mp4 using Megui.. but the problem is that the video came without the subtitles that were in the original file , the .mkv.. im wondering how do i get to convert the video with the subtitles? o_o

[Sharktooth]

extract the subs from the .mkv with mkvextract, convert the subs into .srt or TTxt format and mux them with your encoding using mp4box (or megui muxer, or YAMB...)

[Knuffi]

if you download the full 3.5 redist it will install sp1 for .net 2.0, also if you go to windows update it will install it - under optional extras, maybe you could place this little info in the read me file so people know :)

edit: if you have a quad core pc should you still use the neroaacenc.exe or move onto the sse version ?

There went something wrong with my .NET 3.5 Installation, I deinstalled and reinstalled and ... voila ... there was 2.0 SP1 :)

When I press the Autocrop button with the movie The Outlaw Josey Wales (PAL Version), all crop values they remain to 0

With autocrop() I get 2,72,716,432, -> L:2 R:2 T:72 B:72

With War movie (actor: Jet Li) all's right.

¿ What's wrong ?

[Sharktooth]

some manual job is required when megui's autocrop fails.
yes... it may fail... nothing is perfect.

yes... but autocrop() don't fail.

Why not to use it ?
Why to reinvent the wheel ?

[dolphinjet]

just to report my previous question:
Updated to newer version of x264 but still got no clue on why the output file is bigger than the original, mp4 to mp4; using lower bitrate (audio/video) with same resolution & fps.
But I tried mediacoder and shrinked the file successfully.
It's just a few unusual cases anyway.

[Sharktooth]

yes... but autocrop() don't fail.

Why not to use it ?
Why to reinvent the wheel ?
autocrop() (at default settings) may fail in other circumstancies.
we prefer it doesnt crop than that it crops too much.
however we included the possibility to do a visual manual crop... so i cant understand what you want more than that.

[bokonon]

has anyone managed to work out what the equivelant of CQ 18 for the new AQ build? Even --CRF 22 gives out a pretty high bitrate

[Sharktooth]

it's source dependant.
however you can disble aq by adding --aq-strenght 0

or

you can tweak the strength and/or sensitivity

[Carpo]

is anyone else getting the error - you seem to be running vista can i ask you to update your .net - after installing vista sp1 ?

and its not from an illegal source, i got it from connect :)

[AB3M@n]

Hello.

I have been using MEgui fro x264 conversions for atleast a month now and everything has been perfect untill one time the AVS creator couldn't analyse an avi I had. So I manually put in the settings and it converted. SO I think ok it must of been ion error in the AVI. Now today when I want to convert something the analyse button makes megui completly hang and megui hangs when importing an AVS. I have reinstalled megui, AVS and CCCP. ANy help here please?

[Sharktooth]

@carpo: uninstall .net 3.5 and reinstall it.
crappy Vista SP1 is screwing a lot of stuff, even drivers...

it only did it twice and now its not doing it :) cant say i have been having any issues with it, in fact the system seems faster - was hitting 99fps last night on an encode - so im happy

Nvm...I solved my problem. The Avi I created had errors in it (Computer problems...:()

[vassie]

I have uninstalled and reinstalled .net 3.5 about 10 times now, and I am still being prompted to upgrade .net on my Vista SP1 machine.

[Knuffi]

Just a guess ... look at the "ProgramData" folder on your system HD (it's a hidden folder by default). Check the rights to it by right clicking it an choosing the properties. Under security there should be some entries about who has which rights to access the folder. In my case there were no entries. I put some in (Admin, system, ...) and the next time I tried to install, it worked. I found that problem in connection to another tool (nhancer).
Please ask someone (here on the forum or elsewhere), which groups should have which rights on that folder (I did just a guess ...)!

I have checked the permissions on that folder and they are fine, I guess this is a bug in MeGUI?

[rebkell]

I haven't read all of this conversation, but are you running megui as Administrator? I got the same prompts over and over until I always started megui as Administrator.

[rack04]

This is going to be a terrible explanation but I'm going to try my best. I'm unable to encode using X264 or XVID. I get an error immediately when the encode starts but there is not an error output in the log. SNOW and LMP4 both work, not that I use them but for testing purposes they both work. Here is the script I'm trying to encode:

# Set DAR in encoder to 12187 : 5000. The following line is for automatic signalling
global MeGUI_darx = 12187
global MeGUI_dary = 5000
DGDecode_mpeg2source("E:\Harry Potter\VTS_01_1.d2v",info=3)
ColorMatrix(hints=true)
#deinterlace
crop( 2, 58, 0, -64)
Spline36Resize(720,352)
RemoveGrain(mode=2)

Script plays fine in MPC HC. It's not just this script its any script will crash X264 and XVID. I just don't understand what could be causing this problem. I have completely uninstalled and reinstalled MeGUI and AviSynth.

I am using the following:

[Information] Version information
-[NoImage] MeGUI Version : 0.3.0.1004
-[NoImage] OS : Microsoft Windows XP Professional Service Pack 2
-[NoImage] Framework used : 2.0 SP1

Well I think I have this solved. I deleted all plugins in the plugin directory and it works. I think it was a conflict with AviSynth.dll in the plugin folder.

[Carpo]

is a 64bit OS an option now with megui and all associated tools or is it still very much 32bit, i would like to go 64bit but need to know if all the programs i will use will work on there

[rebkell]

You deleted all the .dll files in the Avisynth 2.5/plugins folder? Surely, that's not what you're saying, but I'm not understanding what you deleted.

[rack04]

That is correct. I deleted the .dll's and downloaded them using the MeGUI auto update.

[rebkell]

That is correct. I deleted the .dll's and downloaded them using the MeGUI auto update.

OK, I didn't realize that megui would update all the avisynth dlls on it's own.

I can't get DirectShowSource to work with mkv/mp4/x264 source files to encode to xvid, I wonder if that might work for me.

[rack04]

OK, I didn't realize that megui would update all the avisynth dlls on it's own.

It won't. I modified the autoupdate.xml to force the update.

[rack04]

I have two OTA HD recordings that I wish to encode using MeGUI but for some reason the source can not be detected using the analyze in the AviSynth Script Creator. What can I post so that someone can help me figure out what deinterlace settings to use?

EDIT: Forgot to mention that these files are 720p @ 59.94fps.

[mroz]

Assuming it isn't mixed, just find a clip with lots of motion & step through it using something like VDub (anything that will show the content of each frame without applying lots of processing to it first), a frame at a time. Look for frames which have combing around movement & for 20 or so consecutive frames post whether they show any significant interlacing or seem to be progressive.

The resulting pattern tells you all you need to know in most cases (excluding rare horrid messes).

For example, if every frame is interlaced, you need to deinterlace; yadif is nice imho.

OTOH if you had a pattern of iipppiippp... this would be typical for film that had been hard telecined to ntsc frame rates & so would need ivtc

I'm not sure what patterns are typical for 720p, as it's been a while since I touched any. Iirc I think I've seen iiiipppppp, where every other frame is a duplicate, so keep an eye out for duplicate frames too & report on that.

Or just put a short clip up on some file sharing site.

How much of a clip do you need and where is a good place to host the file?

[mroz]

See http://forum.doom9.org/showthread.php?t=130290

A few suitable seconds would do, but 10 to 30s would be nice. Just make sure it's from a well lit section with lots of motion - not inside a dungeon with the lights out.

I'll post something when I get off of work. Since the files in question are Lost and Eli Stone I doubt there will be alot of motion. :)

Here (http://www.mediafire.com/?2eiozmlx8xy) is a sample 720p OTA HD MPEG2 clip. Using the analyze function of MeGUI's AviSynth Creator I get source not detected. Could someone analyze the source and tell me how to convert the 59.94 framerate to 23.976? Thanks.

[mroz]

rack4: no interlacing, just lots of duplicated frames. The source you want to recover is the sequence abcdef... The material you have presents as aabbbccdddeefff...

So, the pattern repeats with a length of five. From each such block of five frames you want to throw three away.

In Megui>AVISynthScriptCreator>Filters, set source as M-in-5 Decimation Required & set M as 3. You can now set the 'deinterlace option' to Tritical Decimate.

If you look at the resulting AVISynthScript you should see the line:
TDecimate(cycleR=3)
Just before any cropping or resizing is done. That's doing the job for you. Preview the script to make sure before encoding.

there is one weird stretch in the clip, from frames 396-408, it's typical LOST, they always seem to have some weird stretches that just don't make any sense. I've been using TDecimate(CycleR=3) for all the new episodes this year and for the most part they have looked pretty good, we've (Plugh and I) discussed these weird cadences before.

/gets files back out of bin

Oh yes, so there is. Ignorable I assume, but still, it would be interesting to know what processing led to that.

[shadesters]

Hi all, I recently got a movie in MKV and I am trying to re-encode it in divx format... I start the encode and everything is running fine... I have a quad core, and I set it to 3 threads but it only uses 50% CPU... anyways, thats not my problem... 20 mins into an encode my monitor goes blank and I cant restore it... I tried turning screensaver off, and nothing works... computer is still on, I think it may have crashed or something... tried multiple times, still nothing... No overheating, so I doubt its any hardware problems... This is since the newest version... any help would be appreciated

Hi everyone, im trying to convert some videos with Megui but it doesnt convert the audio when nero audio codec is selected, says "error".

I remember that nero audio encoder doesnt get downloaded in the updates, ive instaled nero on:

C:\Programas\megui\tools\ndaac

can anyone help?
Thanks

Yeah, I noticed this bug a while back. MeGUI does not work with the optimized NeroAacEnc, for some odd reason. Just forgot to report :p
