MeGUI: General Questions and Troubleshooting Thread

[ZZZERO]

It's been a month or so since I encoded something. I used to get around 33fps encoding with x264 to mp4 on both film and interlaced sources. All of a sudden I'm getting less than 10fps with film sources, but my interlaced stuff still encodes at 33fps. Has something changed recently in the way megui handles film sources? Here's one of my scripts that encodes really slowly

LoadPlugin("C:\Program Files\megui\tools\dgindex\DGDecode.dll")
DGDecode_mpeg2source("E:\800FL\800FL.d2v", info=3)
LoadPlugin("C:\Program Files\megui\tools\avisynth_plugin\ColorMatrix.dll")
ColorMatrix(hints=true, interlaced=true, threads=0)
fft3dfilter(interlaced=true)
LoadPlugin("C:\Program Files\megui\tools\avisynth_plugin\TIVTC.dll")
tfm(order=1).tdecimate()
crop( 4, 6, -8, -2)

LanczosResize(576,432) # Lanczos (Sharp)
#denoise


Could it be a cpu utilization problem? I have an i5 quad core and I let x264 automatically set the number of threads. It looks like film encodes are not using a very high percentage of cpu power when compared to an interlaced encode.


Here's a typical script for one of my interlaced encodes.

LoadPlugin("C:\Program Files\megui\tools\dgindex\DGDecode.dll")
DGDecode_mpeg2source("E:\PR23\PR23.d2v", info=3)
LoadPlugin("C:\Program Files\megui\tools\avisynth_plugin\ColorMatrix.dll")
ColorMatrix(hints=true, interlaced=true, threads=0)
fft3dfilter(interlaced=true)
Load_Stdcall_Plugin("C:\Program Files\megui\tools\yadif\yadif.dll")
Yadif(order=1)
crop( 12, 6, -12, -6)

Hi to everyone and sorry if my english won't be well but I'm italian :)

Is possible to add cleanup job manually? I meant without one-click feature.
That's my procedure, I:
1) Open File indexer to make the d2v file
2) Open it with AVS creator and save the AVS script
3) Select the profile in the video encoder settings
4) Set the right bitrate with bitrate calculator and insert it in the profile
5) Click Auto-encode to generate all the jobs automatically.
6) At the end of the job I have to clean up by myself.

These passes works good but I'd prefer cleaning up to start through jobs

Thanks in advance

[Sharktooth]

@luke83: 4 is useless. Auto-Encode window will ask you for a target bitrate OR filesize too.
also, it's not clear to me what you mean with "i have to clean up". clean up what?

@ZZZERO: ensure you're using the same encoding preset as before.

[luke83]

@luke83: 4 is useless. Auto-Encode window will ask you for a target bitrate OR filesize too.

Clean the working folder where the files are (.d2v, .avs .ac3 ecc...)

When I use the "One-Click" encoding, one more job appears at the end named:"Clean up". This job deletes all the file in the working directory.
When I don't use "One-click", Megui doesn't add that final job. In this case the last job is "Muxing".

I want to know the way to add "clean job" manually. So I haven't to open working folders and delete all the files by myself :)

[ZZZERO]

I'm using the same preset as before. In fact, I'm using the same preset for film encoding and for interlaced material. The only difference between the encodes are these script lines:

Film script:
LoadPlugin("C:\Program Files\megui\tools\avisynth_plugin\TIVTC.dll")
tfm(order=1).tdecimate()

Interlaced script:
Load_Stdcall_Plugin("C:\Program Files\megui\tools\yadif\yadif.dll")
Yadif(order=1)

Both are generated from the MEGUI analyze function.

The film script results in 10fps, the interlaced script gives me 33fps. I don't have an old film script so I don't know if MEGUI has changed some parameter in the scripts it creates, but I do know that I used to get at least 33fps when encoding film sources in the past. Now I'm getting a quarter of that speed and I don't know why.

[Sharktooth]

@ZZZERO: inverse telecine is a more complex process than just deinterlacing. it's pretty normal.

@luke83: the clean up job cant be added outside one-click encoder.

[Carpo]

When looking at a CSI disc in DGIndex and DGIndexNV both say that the disc is interlaced, yet when i go to make the avs file in MeGui it says that the stream is progressive, so which is right? Which is it? should i trust MeGui and let it make a .avs for progressive?

[nurbs]

From the DGIndex manual:
Frame Type - Displays Interlaced or Progressive depending on the value of the MPEG2 progressive_frame flag. Please be aware that this merely describes how the frame was encoded; it says nothing about whether the content of the frame is progressive or interlaced. It is common for progressive video to be encoded as interlaced, and vice versa.

[Carpo]

Thanks Nurbs, helps me to understand a bit more. Yes RTFM is a good thing, maybe i should do that after coffee :-)

[Sharktooth]

megui should be more accurate coz it tests for interlacing/telecine. however it could be wrong at times.
just watch the preview before analyzing the source. you will clearly see interlacing/telecine artifacts in high motion scene if the source is interlaced or telecined.

[luke83]

@luke83: the clean up job cant be added outside one-click encoder.

ok, thanks

Now, one more dubt :D
I think the Analyse pass that looks for deinterlacing source is executed when I use One-click Encoding too.
However, is One-click encoding able to find if the video is Anime? And is the bitrate calulated or I have to set manually?

I'm sorry to annoying you with these questions but I'm going to convert many dvds (Movie, Specials and Series). For this reason I want everythings works good ;)

[Sharktooth]

one click doesnt know if the source is anime or not, also if you click "show advanced options" you will find a lot of interesting things... ;)

Hi. I googled around and found this error listed elsewhere on the site, but i did not quite understand the suggested causes of the issue. So i am posting a request for help here.

i have a .m2ts file in a BDMV folder. i am trying to encode using megui. i am using windows 7 x64 bit. i have downloaded the newest version of x264 and placed it in the megui directory, in the appropriate folder.

the avs script creator loads the movie, i can see the preview window, i set resolution and encode options...que the job, and then the log shows the following: (the worker timer continues on, saying "processing" though the error shows in the log as soon as i start the job.

[Sharktooth]

have you read the forum rules, expecially the rule 6?

[kristiXS]

have you read the forum rules, expecially the rule 6?
ah, i didnt realize that was in there...i edited the path text in the avs script, that should resolve the issue.

So, any advice on the problem at hand?

[LigH]

No real idea ... only a guess that the command line might have been truncated due to its length, and the cut was between two dashes of a parameter, leaving the left one interpreted as input file name.

Try to shorten the path name of "G:\MeGUI_0.3.5_x86_WithoutInstaller_OfflinePackage" (e.g. to simply "G:\MeGUI") by renaming the folder, that will reduce the command line 2 times (appears in the CQM file option too).

[luke83]

one click doesnt know if the source is anime or not, also if you click "show advanced options" you will find a lot of interesting things... ;)

eheh, tks. I got it ;)
However I need of Anime support at this time :)

[Sharktooth]

it cant be possible. source detector cant know if the source is anime or not. every software that supports custom parameters for anime needs you to MANUALLY specify if the source is anime or not.

[luke83]

it cant be possible. source detector cant know if the source is anime or not. every software that supports custom parameters for anime needs you to MANUALLY specify if the source is anime or not.

yes yes I will make it manually. it's not a problem. But I'd prefer a simple checkbox in the "One-Click Encoder".

[Sharktooth]

you can make an avisynth preset for anime then load it (in advanced options) for anime sources.

[foreverbelmont]

Hi.I have a VC-1 1080i m2ts Anime. After using dgindexnv and import .dgi into Megui and want to create AVS script, which source type should i choose? Interlaced? or do nothing? THX

[Carpo]

tell megui its anime, click analyse, megui will scan it and tell you what it is and what ways (if any) will be used to de-interlace it :)

[foreverbelmont]

tell megui its anime, click analyse, megui will scan it and tell you what it is and what ways (if any) will be used to de-interlace it :)

THX, i have tried it yesterday, but it took a very very long time...4 hours and the progress bar only went forward for about 1 percent...

[Carpo]

it takes a while to do some of the m2ts files i have made here, but never that long, i would suggest checking your hard drive for errors and defraging it.

For me it normaly takes megui a maximum of 10 mins to make the dgi file, and then no more than 20-25 to index it.

[luke83]

Good idea, but I can't find anything about "Anime" in the resulting AVS script.

That is: what's the difference when I check "Source is Anime"? What Megui do when I check it?

[Sharktooth]

the "Source is anime" button enables a different source analysis.

[luke83]

the "Source is anime" button enables a different source analysis.

And what's the technical difference? :rolleyes:

[Sharktooth]

in few words, in anime it is more difficult to detect intelacing/telecine due to the nature of the video, so a different analysis is needed.

[luke83]

Ok. Now, How can I enable anime analysis in the avs script made by myself? So I could make an AVS preset

After updating dgindexnv and some other things, everything is going the right way. THX.

[Sharktooth]

@luke83: it's simple. you cant. analysis is done by megui, not by avisynth.
as i said in a previous post you can make an avisynth preset (in avs creator), save it and reuse from one-click encoder...

[LigH]

Disabling "Save settings in INI file" solved my problems with the slow quitting and the even slower loading right afterwards.

[Kurtnoise]

@LigH: you're off-topic here...megui doesn't have ini files.

[LigH]

Heh - wrong thread, yes.

thank you for the reply. upon your suggestion, i shortened the path and downloaded the freeware AVCHD editor from VSO and remade the bluray folder, voila, it encodes. Apparently there was some issue with either the path being too long to the files or the ripped bluray structure / .m2ts that was readable enough to create an AVS script and play, but caused an issue when encoding. :confused:

edit: it appeared that it was finally going to encode with all apps at this point, as before the edit even another standalone app was stopping, and after doing the above it could encode it. MEgui however is still giving me the error: raw input requires a resolution, could not open input file `-'. sigh. this is driving me crazi...er.

i demuxed the mt2s file into an mkv and ac3...created avs script with the mkv... set it to encode....same stupid error.... ive edited windows 7 settings to use coreavc and xvid codecs by default as i read to do as that can affect decoding.... now i dont know anything else to try.

now another question..
looking at the path, i noticed its sending the command line to
Job commandline: "\tools\x264\vfw4x264.exe" which is the vfw version of x264...is that correct? i thought it should be using the newer regular x264.exe ?

[Sharktooth]

nope, it is a pipe buffer for x264. it will be removed in future versions.

since the avs script is based on mt2s demuxed using the tool in megui to an mkv vid file...its obviously not raw. corecodec is my video decoder for x264 / h264, is it some problem with it maybe? x264 thinks im feeding it raw because.....??? i assume im asking this in the correct forum area considering im using megui, if not please point me to another thread.

the only mention of this error is in this thread:
http://forum.doom9.org/archive/index.php/t-135258.html
and its regarding actually sending it raw info...i dont think it applies to feeding it mkv video with the avs script?

[Sharktooth]

have you indexed the mkv file?

[kristiXS]

have you indexed the mkv file?

yes, i tried indexing the mt2s file and extracting raw while i was at it...i also tried indexing the mkv i had extracted from mt2s... always the same error. i set it to encode to xvid and it started processing, so the problem is just with x264 encoding. i installed ffdshow just now (leaving default settings) and used the tweaker to set it as default windows codec for h264 instead of corecodec, it made no difference in the encode error.

im now trying a different mkv file, which is giving the same error.

so i just noticed, some behavior about the avisynth script editing:
if i make avisynth script profile other than scratchpad so i can add ConvertToYV12() at end and save it, when i index and it loads into avisynth script creator, im able to crop but the resize option is greyed out if i have clever anamorphic checked. if i load the mkv directly into script creator without indexing, its not greyed out, even with clever anamorphic checked. If i use the scratchpad script, i can still resize regardless of whether i indexed or not.

after creating the script, when i click to que the job, i get a message with this file: it is stating the clip is in I420 not yv12, even though convertToYv12 has been added to the script...continue anyway? i said yes...then get my favorite error message again: raw input requires a resolution / could not open input file.

i went back and just using scratchpad profile, got the same clip is i420 message, said yes to encode anyways...and this time, i finally started encoding without an error.

so it seems it was just the script the entire time (and only for x264, xvid was ok with the modified default script lol). maybe some warnings are needed to avoid an ID10T error like that... hours of fooling with this because of it needing to use scratchpad rather than a saved default script....

this is not a megui's fault...but eac3to which is not "up-to-dated" within mkv files produced by makemkv.

[sebus]

Is there a way in GUI to add the idx subtitles (or maybe even Bluray sup) for hardcoding (to ie xvid) or it must be done by hand in avs script ie

LoadPlugin("C:\Program Files (x86)\megui\tools\DirectVobSub\VSFilter.dll")
VobSub("C:\Users\Danny\Videos\Films\DRACULA\English.idx")

[Music Fan]

Hi,
I would like to create keyframes on certain frames in a video to put chapters on these frames (I guess it's better to put chapter index on keyframes, at least for standalone players).
I saw the "zones" tab and the "chapter creator" tool but I don't know if one of these serves to create keyframes.
I also would like to know if the chapter creator accept a txt file with the numbers of frames I'd like to use as chapters points (simply a list of numbers, without timing, as we can do in DivXMediaBuilder to create chapters).
Thanks;)

[Kurtnoise]

@arnuche : what kind of sources do you have ? you cannot insert keyframes as it...you have to reencode your input as well. MeGUI has a semi-automatic option to insert keyframes for chapters during encodes.

and yes, UV is dead but you can still find me around here (http://www.cyrille-borne.com/forum/) if you prefer froggies people...

I'm Music Fan here :D
It's an avisynth script, I know that I can't add keyframes in a video without reencoding it.
Do you mean that if we open a chapter list (in txt file), MeGui can create keyframes on these frames ? If yes, how ?
I choose first the frames on which I want put chapters with Virtual Dub and I create the txt file with the numbers of these frames.

[Sharktooth]

ogg chapter format.
the format is described here: http://code.google.com/p/subler/wiki/ChapterTextFormat

[Music Fan]

Thanks, but a simpler format is enough for me. Can't we import number frames as I described above ?
I don't need names for chapters, I just want to create keyframes with MeGui.

[HeadlessCow]

I don't need names for chapters, I just want to create keyframes with MeGui.

You can create a qpf file and add it to the x264 config before you encode the video.

The qpf file just has a list of frame numbers, frame types and quantizers (use -1 for quantizer if you want to let x264 decide).

Sample qpf file.

0 I -1
2374 I -1
4527 I -1
17113 I -1
31883 I -1
34040 I -1

But that is done by hand in the script, correct?
Or did I miss something obvious?
