MeGUI: General Questions and Troubleshooting Thread

[hello_hello]

Try either of these in the custom command line section (for ffmpeg). I'm not sure which is the better quality.

-af "atempo='20.0/22.0'"

-af "rubberband=tempo='20.0/22.0'"

Or try this script. https://forum.videohelp.com/threads/384967-AudioSpeed-script

AudioSpeed(20,22, PitchCorrect=true)

There's a newer version here. I haven't uploaded it to the thread yet. Maybe I forgot, or hadn't tested it much. I can't remember. Not that much can go wrong.

anyone please give me some tips to get better quality as source file in megui
some settings

please help me guys

[Octo-puss]

How do I rotate video with MeGUI? It's probably done through script creator, but I don't understand this stuff one bit.

[LigH]

@ Octo-puss:

Prerequisite would be learning AviSynth (http://avisynth.nl/index.php/Main_Page). The installation of the legacy version 2.6.0 (https://sourceforge.net/projects/avisynth2/files/AviSynth%202.6/AviSynth%202.6.0/) contains a quite good introduction guide as set of HTML pages (you will want to restore a more modern installation of an MT version afterwards, possibly even AviSynth+); I did not check if it is also contained in a source archive, in this case you may be able to avoid an installation.

StainlessS also offers the documentation as a CHM file (https://forum.doom9.org/showthread.php?t=152781) (reading that in a modern Windows may require the installation of some WinHelp32 tools, but its advantage is being a compact archive, and you don't have to install a legacy version just to get the documentation).

To rotate the video left or right by 90°, you can use the Turn filters (http://avisynth.nl/index.php/TurnLeft); Turn180() creates a result equal to both Flip (http://avisynth.nl/index.php/Flip) filters in a sequence: FlipHorizontal().FlipVertical(); rotating arbitrary angles is more complex and will require a plugin.

@ imsrk48:

Improving the subjective visual quality is an extremely complex field of video filtering which requires a separate thread. It is also independent of the used converter (whether MeGUI or any other AviSynth based tools), but it depends a lot on attributes of each different source file.

It's not a topic for this thread. Except for activating filters already provided explicitly, like some noise filter presets in the AVS Script Creator.

No useless full-quotes, please, they are a waste of space.

No filter ever will repair a ruined video. Lost is gone. CSI-like restoration is a lie. There are ways to make the loss look less annoying, but again: This is not the thread to discuss this huge topic. Make a new one, and provide video samples of the video clip you want to have improved (not just single screenshots).

This is pretty confusing.

rotating arbitrary angles is more complex and will require a plugin.
A turn by 90 degrees + multiples of, is included in Avisynth builtin filters, as is eg FlipHorizontal and FlipVertical,
but rotation by some other non multiple of 90 degrees would require external plugin.

Under the FFMpeg AC-3 configuration dialog, I often use the Time Modification option to slow down with pitch correction from 25 to 24 FPS. I would like to know if it's possible to do the same but using other custom FPS. For example, at the moment I'd like a 22 to 20 time modification, with pitch correction. I guess one can achieve this using the command line in the "Extra" tab, but I don't know how to do it or where exactly to look for it. Thanks!

Try either of these in the custom command line section (for ffmpeg). I'm not sure which is the better quality.

-af "atempo='20.0/22.0'"

[hello_hello]

The first line worked great, thanks. What if I wanted to slow down without pitch correction?

You can't do it with the atempo filter, but you can do it with rubberband this way:

-af "rubberband=tempo='20.0/22.0':pitch='20.0/22.0'"

There should be a way to do it by speeding the audio up with the asetrate filter and then resampling it, but I couldn't seem to get it to work. I'm not very clever with ffmpeg.

[pooksahib]

Hi. My audio setting has changed from QAAC to AC-3 which I can only assume was caused by one of the recent Updates. It happened once before which is why I check the settings after every Update but I must have forgotten this time.

Is this a glitch in the Update procedure or is there something I can do to preserve my preferred settings? Thanks.

Which audio settings have changed? The ones in the preset or has only a different one be selected? If yes, where?

[pooksahib]

Hi Zathor, sorry for the delay in my reply. I have QAAC enabled and that's the audio I always use. A few days ago, I was putting 2 scripts into the queue and once more noticed that in the audio Encoder settings, QAAC had been replaced by AC3. I've no idea how it happended other than it must have had something to do with me adding/removing/adding scripts.

Until it happens again and I actually SEE it happening, I doubt there's anything you can do. Thanks for your interest, though.

[Zathor]

I assume I found & fixed it in 2898.

[TakuSkan]

I am running a One-Click batch process of 28 TV episodes. So, each file is identical in video properties other than the file size.

I've been looking for instructions on how to run Megui's one-click batch process to encode 5 or 6 TV episodes on a DVD for days now. All the episodes are in one single VOB set, each in individual PGC chain sets. I've been using Megui to encode movies on DVDs for years by selecting the main VOB set for the movie where the indexer may present me with several PGC sets if present. But I've never tried to automate the process of batch encoding multiple episodes, and have never used one-click before.

I tried one-click by selecting the 1st file in the main VOB set like I would for a movie, and then selecting all of the PCG chains that have the same episode length. I get a message asking if I want to process all x tracks with the current scratchpad settings. I enter a leading name. And the job is automatically cued when I click OK. But running the job results in an error. Selecting the entire VIDEO_TS folder and following the same process of selecting all PGCs results in an error too.

Can someone point me to instructions on how to accomplish this if it's available somewhere? Handbrake makes the process pretty simple by cueing each PGC set and then running the cue. But I like to use the old Nero AAC encoder to minimize output file sizes which I can only do in Megui.

[Zathor]

The process you described does work. Could you please upload your full log files with the error so that we can check what does not work?

[TakuSkan]

The process you described does work. Could you please upload your full log files with the error so that we can check what does not work?

I found the error was being caused in Megui globally no matter what I tried to encode because I'd improperly modified the AviSynth profile in the one-click advanced menu. Resetting that to defaults got me encoding as I'm used to without using one-click again.

I'm running the one-click to batch process those multiple PGC episode chains again. But I'm noticing a 'VTS_01_1_Video.264' file being created that's over the estimated size for 1 episode at the bitrate set. But being new to this, I'll let Megui proceed and see what's generated when all jobs are completed.

[TakuSkan]

Okay... something's not right. The 1st out of the group of episodes just completed as 'Disc 4_VTS_02_2.mkv' at 2.28GB where it should have been 200MB. MediaInfo shows the ABR set at 15.0 Mb/s where in the x264 scratchpad it's set to 844kbps. Demuxed h264 was 2.15 GB and AAC was 23.9 MB and audio & video way out if sync.

It's gone on to process the next episode and I can see a new VTS_01_1.VOB file being created that's already looking too big.

I'm sending you a pm with the log and one-click profiles Zathor. I had better luck with a fresh copy of Megui producing a 183MB mkv with Nero encoded audio. But the audio & video ended up being out of sync. I've never had sync issues when I index & set x264 & Nero to encode one of the PGCs, and mux them manually.

Thanks for providing the files. To be honest I do not see the oversized issue there. Based on the log the final file is

That was from the log in the Megui2.zip that was for the encode I did with a fresh copy of Megui. As I mentioned, it completed with the correct file size, but the audio was out of sync with the video for some reason.

The log in the Megui1.zip file is the one from my original copy of Megui. In that log you'll find these entries:

It looks like it was encoding all PGCs as a group.

There's a number of other odd things in there too like specifying "Cropped output resolution: 656x480" where it should have been 640x480. And "LanczosResize(656,480).AddBorders(32,0,32,0) # Lanczos (Sharp)" where it put in black bars on the sides.

How to set MeGUI for auto add track name or auto set a language for all audio tracks?

How to set MeGUI for auto add track name or auto set a language for all audio tracks?

Where? In OneClick or somewhere else? If somewhere else - no chance, if in OneClick you can configure that in the profile.

[imsrk48]

[LigH]

Nobody here would recommend you to use DirectShowSource (not as long as any other plugin still works instead).

And in general, MeGUI cannot know the language of a track ... not all sources even have any flag which could be read.

[TakuSkan]

Well after getting an handle on Handbrake and learning how to configure it properly, I was finally successful at ripping all TV episodes in individual PGCs from a set of DVDs with about 5 episodes per disk. But even Handbrake threw me a curve ball when I added sharpening to the mix. Ended up having to crop a 2 pixel green line on the right edge that enabling that caused.

Try as I may, I never got any copy of Megui to do the job properly. Either I needed to configure something in the 1-click settings, or Megui just didn't like these DVDs. Has anyone else run into problems ripping multiple titles/episodes from a DVD where all episodes are in one single VOB set, like VTS_02_x.VOB?

[imsrk48]

Sorry, took me some time to find time :)

In your OneClick profile you do have selected a target file size of 2,19 Gb (for each file) and based on that it tried to get to that size.


There's a number of other odd things in there too like specifying "Cropped output resolution: 656x480" where it should have been 640x480. And "LanczosResize(656,480).AddBorders(32,0,32,0) # Lanczos (Sharp)" where it put in black bars on the sides.
You do have selected in the x264 the --bluray-compat option based on which specific resolutions will be forced (incl. black borders if needed). Reason for that is that you do have selected the AVCHD device output type. If you do not need Blu-Ray compatible output files I suggest to use the latest iPhone one (4 something).

Hmm... Those are all settings set in the x264 scratchpad that have been working fine to rip/encode/transcode every other video file I regularly have Megui process via File Indexer. One Click should be seeing the ABR 844 kbps that's set in there. Didn't think I had to tweak any One Click settings after choosing the video input and being prompted it would use scratchpad settings.

EDIT: But I just checked and yes, for some reason 2.19 GB is in fact set in OneClick advanced settings as an output size for some reason. I'll have another go at ripping the set of PGCs and report back, hoping not to get that out-of-sync issue again.

[TakuSkan]

I'm still having the problem with audio / video sync like I had using a fresh copy of Megui. I'm starting to think it's something to do with how the multiple episodes are written into the single VOB set on this DVD that Handbrake deals with, but OneClick may be struggling to recognize properly.

MediaInfo reports a frame rate of 23.976 FPS for the 1st ~1GB VOB file of the set, VTS_02_1.VOB. But when I load the IFO file for the set, VTS_02_0.IFO, it reports 29.97 FPS. And the mkv file OneClick creates only shows video for 20:46 out of the full 26:01 the episode runs. From 20:46 to 26:01 the video is black while the audio still runs out the full 26:01.

It also seems to be having problems dealing with processing the anamorphic 720x480 into 4:3 640x480 video. No matter how I try to set input and output ARs in the advanced menu, I'm failing at getting proper output. With input DAR set to ITU 4:3 NTSC (1.367377) and output to 640x480, 1C keeps putting black bars on the sides. With ITU 16:9 NTSC (1.823169) set and output to 640x480, the output is stretched to 720.

And 1C keeps defaulting back to the 2.3 GB output size when I start another run. I don't see a menu to reset default settings. And I don't see the value in Megui's settings.xml where I might be able to edit it out..

[Zathor]

I think it may be related to you video source beeing 29.97 with pull-down to 23.976 as this also explains the missing minutes in your output file.

You can also see this in the log:
---[Information] [12/23/2018 3:42:32 PM] Film percentage: 100
---[Information] [12/23/2018 3:42:32 PM] Applied force film
So DGIndex does this.

Any chance you can upload a sample of the inout file for me? E.g. cut from PGC 3 only a VOB ID.

Btw you get the black borders as you do have to remove the -bluray-compat switch in the x264 settings ==> select another output device in the x264 profile.

And if you want to reset OneClick to default settings open the profile you want to reset (=configure) and "load defaults". Or do it the hard way, delete all profiles in MeGUI\allprofiles you want to have reset.

[RyaNJ]

I've run into a little difficulty when using DGIndexNV. It keeps telling me that the file cannot be opened (after manually creating it via the AVS creator). It's really unusual since the file seems to be where it should be and it doesn't appear to be corrupted. Any advice on debugging what's going on here?

Does it happen with all files or just this one?

Does it happen when using DGIndexNV standalone (not through MeGUI)?

Not quite sure what you mean by "cut from PGC 3 only a VOB ID", but I PMed you with a dl link for what I came up with.

[LigH]

"Program Chains" (PGC) and "VOB IDs" are basic terminology everyone ripping a DVD Video should understand... more or less. ;)

If you ripped the whole VIDEO_TS folder content (including IFO files), PGCDemux would support you doing what you need.

If you want to learn more, start with "DVD Demystified".

Ah, thanks LigH. I've been ripping DVDs with Megui for quite a while, but pulling out individual episodes from a single VOB set is something I've never had a reason to try. I did download PGCDemux when I started to figure out how to do this, and see it's included with Megui. Okay, I've had PGCDemux create a PGC VOB from PGC 3 which resulted in: VTS_01_1.VOB (1GB) and VTS_01_2.VOB (76MB).

I'm still not all that clear on what Zathor means by "a sample" .. "cut from PGC 3 only a VOB ID" Does he mean those 2 VOBs PGCDemux made from PGC 3? Or something I can extract or edit out of them?

[doomleox999]

How can I achieve this kind of result with MeGUI? I want to encode "old" anime. Which AviSynth plugins should I download, where can I get them, and how should I write the script?

The two things I'm not sure if I want are the change of colors and thickness of lines (if you pay attention in the "restored" screens the lines are thinner).

MeGUI is an encoder, what you ask is not really in the MeGUI domain.
What kind of result?, you say what you do not want, but not what you do want. (and we are I presume to take it that the src is on the left).

It would be my guess that nobody knows what you want.
