MeGUI: General Questions and Troubleshooting Thread

[ricardo.santos]

but im not getting any audio encoding done with any of the encoders, winamp, faac or nero

ita a small vob file with ac3 track

some "thoughts":

1- Automkv encodes the avisynth script and ac3 file created by megui

2- i formated my pc last week and to avoid downloading all the megui 3rd party tools i backed up the megui folder and copied it to same place afterwards, does that affect megui inner workings?

also, does megui download any filters to avisynth plugins folder? because i might be missing some(ac3 decoder?) because of step 2.

EDIT: yes like i thought, nic audio was missing from avisynth plugins, its working now.

thanks everyone for the help

When I try to encode an MKV into an Xvid file with a profile that worked before, xvid_encraw.exe gets an error and needs to close like 1/4 way through the encoding process... I closed all processes, and I have no clue why this is happening... Seems to be since the update... anyone know where i can get the last version of xvid_encraw.exe so I can test this theory? I have no clue whats going on...

[Sharktooth]

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
It's not megui... it's a nero bug...

I have had problem to encode a movie for MP4 format. The video script is this:
DirectShowSource("H:\Rurouni_Kenshin\[AnimeP2P]Rurouni_Kenshin_Movie_CD1.avi", fps=23.976, convertfps=true, audio=false)
ConvertToYV12
DeGrainMedian(limitY=2,limitUV=3,mode=1)

The log of the error:

[shadesters]

megui already includes the latest version

Yes I know but I meant the version just before the newest... I already forced an update in MeGUI twice just to make sure the file wasnt corrupt...

I am in the process of encoding a tv show and it seems to be working fine... its long MKV movies (in HD) that it seems to be crashing during... I have, however, encoded HD MKVs before the update fine... so i am thinking that this newer version has a bug with it, because I have not done anything to my computer before the update, everythis is the same as it was, but all of a sudden xvid_encraw.exe is crashing 25% thru encodes...

hmm, sorry, after restarting MeGui, the error disappear.

[Carpo]

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

only time i have had this is when you try to use the sse2 version of nero enc with an amd cpu - and they are aware of this - seems someone used the wrong compiler :p

[Sp00kyFox]

hi dudes
is it possible to add several encoding jobs at once?
I have to encode many little files and it just sux to do the very same clicks with every avs file again (i've already generated all avs files with dgindex)

[Carpo]

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


more details are welcome...

it even does this if you install vista (32/64bit) SP1 from the DVD
from Microsoft

Can anyone post an optimal script, for converting clean DVD movie source to Ipod touch compaitible Mp4.

I ran some tests using megui, using the PD-Iphone profile, 650 bit rate, and automated 3 pass, 560 * 346 ( i think) and the quality was good, but still seemed a bit pixelated and blocky at times (even with 3 passes and original dvd source).

I think the problem may be in my script, it is the most minimal, just outlineing the size, and borders, and a bit of saturation.

Can anyone post a good script I can use?

[mroz]

Is Ipone using h264 or an mp4 asp? Even h264 with lots of the nice options disabled might be hardpressed with many sources to give you a good result at that res & bitrate.

If you want informed comment you'll need to post a link to a sample of your source & your existing script. Someone else might then take a look, though probably not me as I'm short of time atm.

Edit: I have no idea what the Ipone profile is, as there's no profile here of that name.

[Drillakilla]

It's basically for my Ipod touch, which uses the same videos as an iphone.

It can take H264 in an mp4 container.

Now I have had some excellent results using this program called handbreak (also h264 in mp4) but that program doesn't give you the freedom you have with megui (if anything the quality was great , but lacked some colour) , so would like to get it right with megui

[mroz]

If the profile is a custom one, post it as well.

Hm, so baseline, no b-frames, 1 ref, no cabac? That's quite restrictive, but if you've got good results at the same spec with handbrake it must be possible.

[Drillakilla]

I am at work now, so can't really post many details, but the Profile was not custom, but came with the megui bundle ( along with profiles for PS3 etc etc )

But it is possible to achieve high quality as the handbrake tests have shown, and I would much prefer using megui and avisynth as it can be tailered to your needs.

Do you think it could be the profile I am using that is not optimum?

[mroz]

What's the profile name? I have a PD-iPhone profile, but no Ipone profile.

Edit: ah, I see you do mean PD-iPhone, having edited your original post :)

I don't know why you're getting better results with Handbrake. You really need to do some further research or get help from someone familiar with Megui & Handbrake, who encodes for such devices. I've never used Handbrake myself, nor baseline with x264.

OTTOMH however, I'd be more inclined to compare x264 command line options first, before looking at any preprocessing the two apps are doing.

I still suggest you post more details when you can though, as I imagine any reader who can help is more likely to, the better you define the problem.

Best of luck.

[Drillakilla]

Yes thats the profile PD-iPhone . I will post some more details this weekend when I am back on my computer, thanks again for your help

[nuaris]

Does MeGUI allow batch encoding for avi/mkv/mp4 video files? If it does, how can I do it? I have around a hundred files to encode and it would take at least half an hour setting them up manually.

Thanks.

[ggab]

good question nuaris, i also wanna know if it is possible, and how :)

[Dark Eiri]

I just updated to Vista Ultimate and MeGUI keeps telling me to update to Framework 3.5, which I already did.
It keeps detecting 2.0 SP1. What should I do?

[Pirks]

Same problem here on my Vista x64 SP1. No matter what I do, and how I reinstall .Net - MeGUI always thinks for some reason that it must use .Net 2.0 SP1 instead of .Net 3.5. I guess we'll have to wait for fix, this forum is choke full of the same complaints as yours and mine. I'm sure MeGUI author is already looking hard into this problem. Patience please :)

[Kurtnoise]

It has already been fixed (revision 478). So, just wait an update...

[Phorze]

I'm having a problem with the preview window, i searched this topic but couldn't find this problem adressed.

My source has an aspect ratio of 2.35:1 which should , according to the net, be approx 1920 x 816 pixels.

I am loading this script:
LoadPlugin("H:\PROGGIES\DGAVCDEC\DGAVCDecode.dll")
AVCSource("Movie.dga", deblock=false)

Well, i am 100% sure the source has a resolution of 1920 x 1080 (letterboxed)
But the preview, even after clicking "orig size" does not display the full resolution it seems. I would guess it's about 10% less both vertically and horizontally. Is there anyway to make it display properly? I want to see exactly what i am cropping when using the script creator later on.

I am testing this on a 1920 x 1080 screen so i'm pretty sure the preview is not displaying the original size.

I have a problem transcoding XviD files to mp4 files for my iPod touch. Specifically, it is an audio transcode problem. I use the iPod 5.5 profile for video and ND-AAC LC 96 kbps profile for audio. I have directed MeGUI to neroaacenc.exe.

I create a simple .avs file using the AviSynth script creator using the .avi file as the video input. I then select the .avi file as the audio input as well. When I select auto encode and it adds the project to the queue, the audio transcode step will preprocess for several minutes before it says it starts encoding. The encode will make no progress before a Windows pop-up appears which says "Neroaacenc.exe has stopped working."

I am running Windows Vista SP1 and the latest stable build of MeGUI with all updates installed. I have the latest stable build of ffdshow. When I take a single VOB file that I decrypted from a DVD, then use d2v creator, avisynth script creator, and use the same video and audio profiles, it works without any difficulties. I have tried using other XviD files to no different result.

I apologise in advance if this has been brought up before, I did a search and could not find any posts on the topic. I'm sure there is some installation/step I must have omitted but I can't for the life of me think what it is.

the fastest way is using the One Click Encoder (Tools/One Click Encoder) and create your own profile for your encodings.

[SpicyViper]

Thanks Sharktooth, works fine now.

[nuaris]

the fastest way is using the One Click Encoder (Tools/One Click Encoder) and create your own profile for your encodings.

I tried that, but One Click Encoder only accepts .vob/.mpg/DGindex files, my input is .avi/.mkv/.mp4. I figured a .bat file that creates .xml job files can help with batch encoding, is there an alternative that's easier and more flexible to changes?

Thanks

I`m new to MeGUI. I have update to the latest version of everything. I am backing up my HD-DVD and Blueray movies to DVD9.

I have been using Nero Recode to recode the videos but I want to switch to MeGUI.

My process is:
1) rip with AnyDVD HD
2) use eac3to to create MKV and AC3
3) Recode MKV to fit on DVD9
4) Merge MP4 and AC3 with mkvmerge

In MeGUI, whenever I try to open my AVS I get the following error:

AviSynth script error:
AVIFileSource: couldn`t open file

My AVS lools like:
AviSource("C:\Users\racerx\Desktop\Movie.avi")
#deinterlace
crop( 0, 142, 0, -142)
#resize
#denoise

(Movie.avi is the renamed MKV created by eac3to)

Any ideas as to why this AVS script is failing to load properly? Thanks.

You can't just rename "movie.mkv" to "movie.avi"

Instead of avisource, try DirectShowSource on your mkv:
DirectShowSource("C:\Users\racerx\Desktop\Movie.mkv")

Can anyone help me with this, I know it is definatly the encoder and not the script as tests using the script on other programs seem to come out with no blocks

Thanks

[Greif]

You can't just rename "movie.mkv" to "movie.avi"

Funny enough, but that is what I do in order for Nero Recode to accept it. It won't accept the MKV file, but if I rename to AVI Nero Recode will work without problem.

I renamed the file back to MKV and AviSynth works fine now. Thanks.

well, I have some ask for you.

You use crop before resize, so your final video are still 560*320. iPod Touch resolution are 480*320, so with 560*320 your movie will be resize again into iPod to 480*274 to fit in touch screen.

Maybe you want use 480*274 Instead 560*320 or maybe you want use crop after resize, so final video will be 476*320, good aproximation to 480*320 :)

In other side, your profile can be tweaked a little. Try this new profile:

Forece Baseline Profile and 3.0 Level
Mode: two or three passes (if you want, you can use turbo mode)
Bitrate: for your resolutions, you can start with 600 to 750
Enable Deblocking: I like use -2:-1
ME algorithm: MultiHex or ESA, or you can try TESA too.
Subpixel: 7 -RDO Level 2
Number Reference Frames: 5
Mixed reference frames: Enable
No DCT & No fast: Enable
All partitions except P4x4

Hi guys, I have a question in the General Questions category:

Is there a way to make MeGUI perform batch operation on video files? What I mean is that I have a bunch of episodes I want to convert, they all need exact same processing in avisynth, the only difference in avs script is thus the file name. Must I copy-paste a bunch of avs files and change file name in each and then manually add and queue each one in megui? Can I just somehow give the directory path and an avs template to go by and let it fill in the names for each file in the dir then auto cue them with selected encoding settings? The avs template in avs creator doesn't seem to work like that. Am I condemned to brute force manual processing?

I did some tests previously on 480 x 274, and it seems to look a lot better on 560 x 320, even though the ipod doesn't display that resolution as native.

It's like when I had my old 42 inch tv, I would feed hd VIDEO through it and they would look a lot better than regular dvds, even though the tele was SD.

Thanks for your help mate, I will try this in the weekend, I know this is a lot to ask but can you just give me a short description of what each of those things does, I would like to understand the changes i make, thanks again

When I started I couldn't even render because there was an error on the first job. This error was appearing without notifications os I could know who to fix the problem. I installed and uninstalled many times to fix this problem. When I found how to fix it, by uninstalling AviSynth, another problem came to me.

I'm trying to render a Counter-Strike clip with the smallest size as possible. The problem is that it gives me a file of 145-150 Kb that I can't even read. I will show you what it does and my settings.

In my test.avs I got this ( I know nothing about avisynth ) :
Code:

AVISource("untitled2.avi")
ConvertToYV12()

When I open my avs file it looks to work properly. My clip is 1280x960

My megui settings are as follow :
http://img219.imageshack.us/img219/6761/confight2.jpg
I use codec x264 and File format MP4.
I click enqueue and start the job.

It only takes 30 seconds each, for a 2 GB file of 56 seconds.

When I go in my folder I find this
Test.mp4 138 KB No images.

I need help and I tried to make an easy understandable thread. Thank you.

I updated megui the other day and all of a sudden I could not encode anymore. I keep getting this error message even though I have been using this settings before without problems. What am I doing to get such message?

Job commandline: "E:\MeGUI\tools\x264\x264.exe" --crf 18 --ref 16 --mixed-refs --no-fast-pskip --bframes 16 --b-pyramid --bime --weightb --direct auto --filter 1,1 --partitions p8x8,b8x8,i4x4,i8x8 --8x8dct --vbv-maxrate 25000 --me umh --threads auto --thread-input --sar 1:1 --progress --no-psnr --no-ssim --output "G:\01.d2v.mkv" "G:\hfyu01.d2v.avs" --aq-strength 0.5 --aq-sensitivity 11
E:\MeGUI\tools\x264\x264.exe: unknown option -- aq-sensitivity

BTW, does it matter where (position-wise) I place "--aq-strength 0.5 --aq-sensitivity 11" in the commandline?

Thanks

^ it shouldn't matter but i'd give it a go without those lines and see if it works. if it does work then that may mean your x264 build is not AQ patched.

[Sharktooth]

you updated megui AND x264... but you modified your profile with --aq-sensitivity that is no longer supported by x264.
remove --aq-sensitivity.

[~bT~]

^ i always thought it was valid? or is this only since latest update?

[Sharktooth]

when AQ was committed the AQ options became:
--aq-mode <integer> How AQ distributes bits [2]
- 0: Disabled
- 1: Avoid moving bits between frames
- 2: Move bits between frames
--aq-strength <float> Reduces blocking and blurring in flat and
textured areas. [1.0]
- 0.5: weak AQ
- 1.5: strong AQ

[EroKaos]

Oh, thanks alot. But how does the --aq-mode works now? Is there any doc that explains how it works?

Don't just paste a link use the Insert Link button, otherwise the forum will garble it up trying to shorten it (it puts ... in there), so your images are unreachable.

[francoeur]

I updated my post on #2040, sry for it. Link now work.

Shraktooth told me to download a stable version, 0.2.6.1046 to fix the problem but it didnt work.
