MeGUI: General Questions and Troubleshooting Thread

[fib0by]

@flb0by: MeGUI normally copies the 2nd pass settings for the first pass. if you select Turbo, it tunes down the settings to have a fast first pass.
however the log is a bit messy. what really matters is what is saved in the log file.

You mean the stuff in C:\Program Files\megui\logs ? Even that doesn't seem to contain the actual options. I did find something that looks like the right stuff for pass 1 for a previous attempt (aborted job) but that was it.

Maybe I should wait until all the jobs are completed and then it will write everything to the log?

[Sharktooth]

it contains the actual option for all passes.
example:
...
--[NoImage] Job commandline: "C:\megui\tools\x264\x264.exe" --pass 1 --bitrate 1062 --stats "***removed***.stats" --bframes 3 --b-pyramid --direct auto --filter -1,-1 --subme 1 --partitions none --me dia --merange 12 --threads auto --thread-input --sar 714:485 --progress --no-psnr --no-ssim --output NUL "***removed***.avs"
...
...
--[NoImage] Job commandline: "C:\megui\tools\x264\x264.exe" --pass 2 --bitrate 1062 --stats "***removed***.stats." --ref 3 --mixed-refs --bframes 3 --b-pyramid --bime --weightb --direct auto --filter -1,-1 --subme 6 --partitions p8x8,b8x8,i4x4,i8x8 --8x8dct --me umh --merange 12 --threads auto --thread-input --sar 714:485 --progress --no-psnr --no-ssim --output "***removed***.264" "***removed***.avs"
...
the log is written at completion. to be sure just close megui when it finished and look again at the logs folder.

Ah yes, that is right. I looked and indeed everything was there after completion. Thanks!

@Sharktooth

Hey mate, thank you for your reply on the other thread. I decided to completely set up a new PC. THis is very old and it was some kind of "Complete Discounter-PC" which has a Core2Duo E6300, but just has a single channel RAM. When trying to encode with Subme7 / Trellis2, I am at 1,25fps, this sucks.

Will MeGUI be able to use all four cores of a quad core ? Just for any calculations, on some "middle" to "insane" settings, to which FPS could one come ?

Thanks in advance,

ANdy.

[flebber]

I have been fiddling with MeGui a little bit now and like what I am getting. There is only two little things I want to confirm, they are essentially very simple.

1) To alter color and brightness etc. I have largely created all my scripts in MeGui and then edited them in VirtualDubMod as prescribed here http://www.doom9.org/index.html?/capture/postprocessing_avisynth.html and then reopened them to finish them off. Is there a simpler, but still effective and controllable way of doing this ?

2) Really simple one Megui clearly has Input Dar for aspect ratio in the Script Creator, But there is no Output Dar option. Is there no option or I just can't find it ?

Cheers

[Sharktooth]

@LOGic, megui uses x264 and it is able to use all the four cores. the problems usually comes from slow avisynth scripts. in that case avisynth wont be fast enough to feed the fames to the encoder, so the encoding threads will wait...
however, first be sure to disable "Automatically set the number of threads" in options (x264 uses a different way to calculate the number of threads) and set "Threads" = 0 (auto) in the x264 preset. that will ensure the correct threads settings for x264.

@flebber:
1) you can use any DirectShow player or anything supporting avisynth to watch the avisynth script preview. Megui offers a preview too during the script creation.
since megui cant graphically support evey avisynth filter (there are tons of them) there's a minimal graphical interface for what the user usually needs.
if you want graphical controls for brightness, contrast and color, please fill in a feature request in the megui feature request tracker on sourceforge.

2) MeGUI uses the input AR for the encoding. Also there seems to be a bug with AR that sometimes happens.

I am basically just using VDubMod as a means to adjust colour and brightness. I will add a request to the tracker as I thought of another option, ... as Virtualdub has 2 colour filters I know of (there is probably more) Auto Levels and Msu Color and Avisynth supports loading Vdub plugins, I could just write a scipt to import filters from vdub into avisynth and save that as part of the prest scipts in Megui... Or I could fill out a feature request:)

2) All of our TV sets in Australia are changing from 4:3 to widescreen to plasma/LCD as PAL is being given the boot for HDTV, with old footage I have got what is the best way to change aspect in Megui?

there is no best as per forum rules.
i think you should read the megui guide and the avisynth manual.

Yes I apologise I should have used "more effective", which is closer to what i meant.

[Sharktooth]

MeGUI supports anamorphic encoding. Have a look at the wiki (link is in the Megui guide sticky thread).

[check]

flebber:
regarding changing the AR: if you mean the actual Aspect Ratio in which the video will display at the end: you should not change this. All of the methods you can use to modify this AR will result in a loss of picture or distortion. You will have to live with pillarboxed display on your new TV.

regarding a better avisynth GUI: you may want to make the next step up in terms of avisynth GUIs to AvsP. There is a thread on these forums about it.

[Greif]

I have been using MeGUI to just encode my HD videos. I then used mkvmerge to join up the video/audio/srt/chapters.

I'd like to save a step or two and just use MeGUI for the joining.

I do have a few questions on using MeGUI:

If I select an AC3 file in the Audio section on the Input tab, is it getting re-encoded?
What is meant by *scratchpad* in the Encoder settings?
Is there a way for MeGUI to import SRT substitles?


BTW, great product. Keep up the good work. :)

[IceMan2]

Hi guys I have a couple questions. First, after some recent updates when I go to create a DV2 file and select Demux all tracks and load the audio. The audio is not auto loading and also I see no data when the creation of the DV2 file. About a few weeks or so ago things were working fine.

Secondly I do alot of TV recording and XviD compression of these shows and I had people tell me that these rips aren't playing back on there DivX/XviD players. Since I dont use or have one these, my knowledge is little as to why this might be. The settings I am ripping at are the basic XviD 1100 kbs fast with no QPel or GMC.

[Sharktooth]

@Greif, megui cant join videos without re-encoding them
Use mkvmerge or other tools for other file formats.
the *scratchpad* contains the default settings, usefull when making new presets from "scratch"
about subs, megui can mux srt subs in various file formats. read the wiki for more info.

@iceman2: first, the behaviour has changed since dgindex 1.5+ has a different audio management. what you mean you "see no data"?
second, megui's xvid configuration doesnt still graphically support hardware devices. it will come soon.

[~bT~]

obviously u will need to change thread= and bitrate

[IceMan2]

your the man ~bT~ I will give that try the next rip and see what happens and wait for feedback from the guys who use these xvid/divx standalone players.

I really love this encoder, the interface is very friendly for the novice user and the amount of control it gives me over each encoding step is hands down the best and getting better. I appreciate all that are behind the scenes making this happen and the one's here who devote there time in helping people out.

Thanks Ice

[tebasuna51]

Maybe old xvid/divx standalone player only play fine with:
Number of B-frames: 1

[Sharktooth]

the old ones, yes, 1 b-frame and packed bitstream.
the new ones, can handle 1b + PB and 2 b-frames and no packed bitstream...

Seems interesting, found http://avisynth.org/qwerpoi/Overview.html and the doom thread http://forum.doom9.org/showthread.php?t=115506 after a quick search will have a look.

[ZZZERO]

Simple question from a noob I hope: When I installed megui I only selected some LAME MP3 audio encoding presets from the long list of offered presets. Now I want to try Nero AAC and use some of its presets. I can't figure out how to import them now? What am I missing?

[Sharktooth]

Options->Update
then find the audio presets, right click->Force (re)install....

Hello,

I did a search for "Audio stream information" but didn't get an appropriate result, so here I go...

I've just ripped a Jaws DVD onto the computer as a set of IFO's and VOB's. I started out (following the wiki guide) by first running "Tools -> D2V creator" and selected "Demux all Audio tracks". After that job had finished, I had files such as "jaws T81 2_0ch 192Kbps DELAY 0ms.ac3" and "jaws T84 3_2ch 384Kbps DELAY 0ms.ac3". However, there is no audio stream information txt file to tell me what language and #channels each ac3 file is. Is there an option in MeGui to enable audio stream information output to a text file? Thanks, this would be very handy.

EDIT: Just out of curiosity (I know this question is a no-brainer, but bear with me), but a video encoded with preset "x264: HQ-slow" will not be playable on a standalone BD player, correct? I'm thinking of archiving my movies at the highest quality (without resorting to insane mode), but I'd want to be able to play these files on a standalone BD player such as a PS3. Thanks!

Format profile : Main@L5.1

Level 5.1 could be a problem although I think I read on the forum that the PS3 plays such files now.
I don't know if it supports variable framerate (if it actually is VFR and I'm not interpreting this incorrectly.

I would demux all the tracks, change the level to 4.1 and mux to mp4 again with 23,976 fps. That could fix it.

edit:
Oh, wait a second, I just noticed it says 29,97 fps and not 23,97. So forget the framerate I gave for muxing.
Didn't you IVTC before encoding?

[check]

@cornflower: yes, ask the handbrake team. That's what the file was encoded with after all... :rolleyes:

Urgh, sorry of this has been asked before, but there's just too many pages to explore :P

I finally took a pretty darn good look at the MeGUIs Wiki tutorials page, and there's just one thing I don't understand:
After I input the AviSynth Script, set the Video Output and set all the Encoder settings, I've got the "Queve analysis pass" button and the standard "Enqueue" button. I do understand that the first one is the analysis pass performed on the AVS as job1 and then job2 is the analysis pass for the video itself then job3 the encoding (at least that's what I figured out from the Queue tab :P), I just don't understand if it's really necessary to perform the analysis pass to the AVS, since it already does that for the video itself.

OMG not only is it a stupid question but I also terribly explained it, I can barely understand myself, LOL, sorry for my f-ed up english.

How can I get besplit working with megui. I tried to use the audio cutter tool, bet it keeps erroring saying that besplit.exe is missing. So I have installed besplit exe to the path C:/program files/megui/besplit.exe . But it still isn't working. Should I be using besplit or besweet. I appear to be missing something simple.

This is the error.

Well... I can sort of agree with that, but it's not the handbrake team that's the problem, it's what settings was used by the encoder and what settings I need to convert it to PS3 format.

Still, I didn't appreciate the condescending tone. Hence my somewhat non-diplomatic response.

@gornot: queue analysis pass is used in situations where you need to run the avisynth script first before you do the encode. The usual reason is you're using a plugin that creates stats dynamically. You don't need to use this, unless you know you do :)

@~bt: no. You are thinking of 'pre-rendering job', not 'analysis pass'

[marklight]

I'm trying to encode some HD MKV's to Apple TV. I downloaded AVisynth and installed the CCCP . I also loaded in the PD-AppleTV preset. I create my script of the file - the only setting I mess with is the resolution. Then I load it into MeGui and choose the Apple TV preset. The only setting I adjust in the preset is the bit rate. When encoding is done, I am unable to open up the resulting MP4 file - in Quicktime I get the error "An invalid public movie atom was found in the movie." I'm including a picture of some of the file's attributes if this helps.

I have a strange problem when encoding anamorphic to xvid with MeGUI.

It seems that the AR-values are not written correctly to the avi-file:

http://img294.imageshack.us/img294/931/meguiaremu4.png

This happens not with every movie, but with every lets say 2nd or 3rd one. So I have to set the correct DAR values from the avs script manually an resave the file.

In earlier versions of megui/encraw, I haven't had this problem.
