MeGUI: General Questions and Troubleshooting Thread

[Avenger007]

I'm using MeGui to convert Avi movies to MP4 for my PSP.
Damn this is getting real hard.
It'll be a lot easier to encode directly from the source (i.e. the sources used to encode to the AVI files), and you'll get better quality.

[Capsbackup]

Thanks for the reply Sharktooth, Capsbackup: when you switch mode from auto 2-pass to 2pass 1st pass, if Turbo is checked, some options will be disabled AND some other will be not available. after encoding the first pass, when you switch to 2pass 2nd pass, you have to re-enable all the disabled options for the 2nd pass . It's not a recommended procedure... but you can re-download the megui presets, select what one you want to use and create two new ones with a different name (mayba append "1st pass" and "2nd pass" to the name or whatever...) but with the same options. after that, modify the 1st copy and select 2pass 1st pass, modify the 2nd copy and select 2pass 2nd pass. when you run the 1st pass, select the 1st pass preset... for the 2nd pass, obviously, select the 2nd pass preset.
I can't seem to enable the greyed-out options that are available with the Automated 2 Pass selection. I would just like to keep the exact same values that you have created for the x264 Standalone AVC-HD, with the option for a profile for 2pass, 1st pass, and then a second profile for 2pass, 2nd pass, like you mentioned. However once I change the automated 2pass selection to 2pass, 1st pass, the values/options that change cannot be changed back or are greyed-out. What am I doing wrong? How do I enable the options that are greyed-out once I change the "pass option"?

[Sharktooth]

in the first pass, if Turbo is enabled, those options will be disabled. it's normal.
ensure those options are enabled and set correctly in the sencond pass.

[Capsbackup]

Ok, i see. I was getting hung up on the 1st pass settings, thinking they needed to be the same as automated 2 pass were. I can make 2 pass, 2nd pass the same settings as automated 2 pass, just not the 2 pass, 1st pass settings. Thanks again Sharktooth, your profiles and efforts are much appreciated!!
Is the quality of the encode reduced by changing from the automated 2 pass method to this method?

[Sharktooth]

no. automated 2pass is just... automated... :)

[Capsbackup]

Thanks again Sharktooth. Good to know. Gives me much more flexible encode times.

[Sharktooth]

there is also one more option... and i think it is even better than creating those presets, etc...
you can use oneclick encoder or the autoencode function or whatever and prepare your jobs (even with auto 2pass presets...)
go to the Queue tab and right click on the jobs you dont want to run and select "change status -> postponed"...
then you can safely start your queue and obtain the same results without getting mad........ ;)

[saint-francis]

you cant. you must extract the subtitles and covert them in a suitable format for the container you're going to use, for example, TTXT (or srt since they will be automatically converted to TTXT) for MP4, srt, ass, etc for MKV, or keep them as an external file.

Why is this? I always extract the subtitles with the MeGUI VobSubber and then simply mux the vobsub format subtitles into the .mkv. Is there a problem with doing this? I have never encountered one.

i just tested with several option and still getting multipart openDML

Found this in the Ziova forums on generating non-multipart openDML:

Settings -> AVI file structure -> tick "use Open-DML output" -> tick "create legacy index", but put "2044" in the "RIFF-AVI" box instead of the default value (which is "1").

that's coz MKV supports vobsubs... MP4 does not...

[saint-francis]

that's coz MKV supports vobsubs... MP4 does not...

Right. Thanks for the clarification on your meaning.

[buzzqw]

mp4 support vobsub/idx, try with kurtnoise13 builds

The source is a 1080i DVB transport stream, that has been edited with VideoReDo, kept in a TS wrapper.

1) Start MeGUI (it is always up-to-date as I let it get the updates).
2) Do the Ctrl-R to open the dialog box.
3) Put in the name of the transport file.
4) The dialog box will pretty much always display that it is a PAL video. 'Fraid not. It never gets it right, when HD video is used (1080i or 720p). I ultimately always change it to 1:1.
5) The resize box always wants to do 640 x something. There is never a choice for 1280x720. I always have to manually deselect the checkbox on the right and enter 1280 and 720. For 1080i, can't 1280x720 be the default?

Where can I change the default setting for the resize boxes? Is an update that applies changes for this GUI going to wipe out a new default setting that I use (if I can change the default setting)?

[Sharktooth]

4) that does only matter for anamorphic encodes and for the suggested resolution. btw, when loading 1080 content, here it displays the correct AR (that's not 1:1 !!! but usually 1.77:1)
5) there's no possibility to upscale (it's useless and we will never add it). so you can enter a resolution up to the input file res.

Well, if it recognizes it as a PAL input, the maximum resolution available for resize will not go over 720x576 ... but his input *is not* PAL, it is 1080(i/p), so I can see that he wants to be able to resize to a lesser resolution and he can't do it right now ...

[MrVideo]

I don't remember seeing 1.77:1 in the list. Can't check now as the computer is busy with a capture and I don't want to do something to cause it to drop aything of the captured stream. I'll look in an hour and report back.

5) there's no possibility to upscale (it's useless and we will never add it). so you can enter a resolution up to the input file res.

Um, you need to re-read the posting, even though you got it right with your response to #4. 1080i to 720p is not an upconvert. It would be a pretty good trick if it was. As a point of reference, I've done 480i 4:3 to 1080i 16:9 upconverts. Why? To take the clean closing credits on a 4:3 file and replace the crap network closing credits on a 1080i file. But I use Vegas Video for that. I use MeGUI to create H.264 720p MKV wrapped files.

So, my question 5 still stands. How do I get 1280x720p as a resize resolution and make it the default?

[MrVideo]

Well, I can do 1280x720. I just have to uncheck the suggested resize checkbox and manually enter 1280 and 720 in the two boxes.

So, for 1080i input, it would be nice if the suggested resize would start at 1280x720. The user could then go down from there.

[Sharktooth]

i misunderstood #5. ill see what i can do.

edit: i just commited a code change so the default resize value is now equal to the original file resolution values.
if you want a custom resize by default create an avisynth preset.

[MrVideo]

edit: i just commited a code change so the default resize value is now equal to the original file resolution values.

OK, a 1080/59.94i file is detected as 16:9 PAL. 1,77:1 is not in the dropdown list. I just use 1:1 as whatever is chosen doesn't seem to matter, as pointed out, this isn't anamorphic.

1:1 isn't a good choice as the resize window is wrong.

Entering 1.77 at that point messed up the resize window, so, I quit and restarted. This time, the 1.77 was remembered. When I selected that, the resize window went to 1920x1072. Huh? It is 1920x1080.

Clicking down through the suggested values, I finally get to 1280x720.. It would have been faster to manually enter 1280x720, less keystrokes. Why so many unnatural video resize values?

Why are only PAL and NTSC anamorphic/4:3 values listed? Where is auto detection of 1080 HD and 720p HD (frame rate is unimportant)? Users don't just import standard definition video, HD video is very popular.

if you want a custom resize by default create an avisynth preset.

And how does one do that? The help button goes to a Wiki page that has zero help.

[Sharktooth]

the correct approximated AR is 1.778:1
btw, something is wrong coz here megui "auto-detects" it.
however there is still something wrong with "suggest resolution". probably cause 1080 is not mod 16.
ill check it tomorrow.

[MrVideo]

When one starts a job from the queue, there is a status dialog box that appears.

Try reading the numbers in the boxes. For all but one entry, all of the text is greyed out to the point that it is extremely difficult to read.

Can the grey text not be grey out, please?

I'd like to be able to actually read how much time is remaining in the job.

Thanks.

[MrVideo]

the correct approximated AR is 1.778:1

Only ever listed to two decimal places in the industry. Hard to narrow down if 1.77:1 or if 1.78:1 is becoming industry standard for the value. One could claim that 1.77777778:1 is even more approximate,

btw, something is wrong coz here megui "auto-detects" it.

Could I have some file that has not been updated somehow? In the AR list, the only values that have checkboxes next to them are the NTSC and PAL anamorphic and 4:3 possibilities and 1:1. There is no 1080 HD or 720 HD selection in the list. Is there a file I should look at that contains this info and see what the date timestamp is?

however there is still something wrong with "suggest resolution". probably cause 1080 is not mod 16.
ill check it tomorrow.

Ya, the 1080 is bastardized, in that it is really 1088 with a flag to say that it is 1080. I didn't discover it until recently, but the local NBC affiliate didn't have the flag set and the video was flagged as being 1920x1088. VRD doesn't like mixing 1088 and 1080 material, even though they are supposidly the same beast. They've since corrected it, but do not know when it was corrected.

[Sharktooth]

that happens when preprocessing the audio. megui cant know how much it will take so everything is grayed out.
after that megui will start correctly calculating all the stuff and it will display the info in a visible way.

Huh? What audio? The job is to turn MPEG-2 MPV into H.264 MP4. There is no audio, zilch, none. Once it starts to settle down in the computation as to how much time is left, the text never turns black.

[Sharktooth]

screenshot plz

[MrVideo]

screenshot plz

Of what? The status dialog box or the not finding the 1080 file format, or both?

OK, here are the three images:

http://vidiot.com/meGUI-1.png
http://vidiot.com/meGUI-2.png
http://vidiot.com/meGUI-3.png

Number 1 shows the resolution selection and that it defaulted to PAL and what the complete pulldown list is.

Number 2 shows the status box during the first pass and number 3 during the second pass. All data boxes are greyed text, not black.

[Sharktooth]

interesting... none of the above happen here...
btw, ill investigate.

[MrVideo]

My lot in life to find things that others don't see :p

Thanks.

Let me know if you need anything else. I'll be out for a few hours.

hi all, first sorry for my english, but i try to explain.

I am using the megui short time and i like to know if is possible to encode serveral jobs(different videos) serially not in parallel. I see that the jobs are at the same time. If is possible one by one i don't know how do it.

thank you very much, adéu.

I think what you mean is to run several processes at thed same time? If so then you can use the "worker" feature in MeGUI. It allows you to assign different jobs to different workers and the different workers will run simultaneously.

While you could do that, I personally would not recommend it, unles you have a Cray.

If you start another job, at the same time, that also does encoding to H.264, the computer would get bogged down such that the total time to get it done would probably be longer than the sum of the two jobs in serial.

YMMV.

hi, no i mean the opposite, run different jobs but not simultaneously(parallel), sequentially: first one i next two(job)...in serial cue
using the worker.
That's form i might encode several videos at night in automatic mode as i am sleeping , i prefer don't encode videos simultaneously.

thanks, adéu.

[poisondeathray]

Operating sequentially is the default behaviour. Just close all the workers except for 1 and queue all the jobs up.

yes i try but the jobs always start in parallel, yesterday i was encoding 2 films but i not was capable to use a serial encode :(
it started simultaneously. i have to create another worker for this? i am using the default megui cueue windows to encode.


p.d: i understand it, i have to create a worker and now seams it is making encode in serial, i was using de default cueue windows to encode, it probably was the wrong way.


thanks, adéu.

[Devils.Advocate]

Hey,

What kinda megui setting would you guys recommend if I wanted to rip a 2:15 hours DVD into a good quality 700MB rip? I have filtered the .avs n stuff. But I cant seem to figure out a video setting.
I also ripped the audio (NDAAC-HE-multichannel 128kbps) but Im not sure anymore whether it's a good choice. Maybe I should lower it?

Any help would be appreciated.

Thanks.

[K.Shinichi]

Hello, hmmm when I encode using megui, the typesetting disappears before one second of the actual frame, if i set it on frame 5000 to disappear, it disappears on 4999 :\ why is that, and how could i fix it

[Sharktooth]

@Devils.Advocate: this is not a newbie help thread...

@K.Shinichi: what do you mean? what typesetting?

[K.Shinichi]

i'm talking about fansubbing
hmmm, the titer shows a second more or disappear before a second from the ending time

[Sharktooth]

more details are welcome

[carlo_0000]

hello

i sow some failed jobs in megui

i restart them but failed again

i notice that my antivirus block them

9/11/2008 19:28:08 Real-time file system protection file E:\bbcd hd\Duffy - Distant dreamer (live @ BBc One sessions) 2008 (aac5.1 HDTV).stats.temp probably a variant of VBS/TrojanDropper.Godog trojan cleaned by deleting - quarantined AUTORITE NT\SYSTEM Event occurred on a new file created by the application: C:\Program Files\megui\tools\x264\x264.exe.

i stoped the nood32 to finish the jobs

this is strange, nether hapend before

[Sharktooth]

every antivirus can detect false positives, nod32 included.
send the false positive files to the eset labs and they will fix nod with an update.

Hi (again^^)

It's possible to mux video .264 (encoding with megui) and audio (also encoding in megui) in a FLV contener ?

I have no problem in mp4 but some friends have problem with player swf and the mp4, and they have no problem with the same player and a flv video. I search everywhere but i know thats its not the player swf who cause problem (i try with the simply player of flash). So i think maeby it's a problem of "adobe flash player".

I would try anymway to contain the best encodage i could make (with megui) and mux in flv for see it's good. it's possible with megui ? or a kind of program like "mp4box" ?:thanks:

[seb37_2]

Ok thanks.
So i have some peoples who see onvp6 in FLV and not see H264 in mp4.
And forcely, i want that every people can see the video.
What can i do ? There is a solution ? I can ask to every body to have the last version of flash player... And i have read that adobe flahs player 9 can't read mp4 before the complete downloading... there is maybe a plugin for that ? To install in my server ?
(something like that ? http://renaun.com/blog/2007/08/22/234/ you know that ?)

[Atak_Snajpera]

And i have read that adobe flahs player 9 can't read mp4 before the complete downloading...
Who told you that???? So How come I can watch .mp4 from youtube (&fmt=18) in real time?!?!? :)

[RyaNJ]

OK guys, in need of a little help here. I'm encoding a DVD movie (originally from a camera that's about 2-3 years old so quality is pretty good). The problem is that I'm having some really bad blocking when it comes to the sky (specifically when the faint-white clouds move and vanish). My current deblocking settings are -3:0 and I'm using Sharktooth's High Detail Matrix. I've tired setting b-frame mode to none to see if that helped and it didn't - I've also tried setting No Fast P-Skip to true as that also turned up in a search but still doesn't seem to have a difference. Everything except the occasional sky problems appears pretty good.

The bit-rate is pretty good, at 1905 kb/sec and I'm encoding with MeGUI using the x264 encoder. Any help here would be appreciated!

Command line currently being used by MeGUI:

program --pass 2 --bitrate 1905 --stats ".stats" --ref 8 --mixed-refs --bframes 3 --b-adapt 2
--b-pyramid --weightb --direct auto --deblock -3:0 --subme 8 --trellis 2 --partitions p8x8,b8x8,i4x4,i8x8

[seb37_2]

I certainly wrong. Sorry.
I search the source of my problem^^

But now it's even clear.

I have two files : one in Onvp6 FLV (bad encoding) and one in h264 in mp4 (very good thanks too megui)

- Every body can read the flv files (with a simple flash player)
- Not everybody can read the mp4 files (with same player)

The persons can't read : windows vista user with player adobe 9,0,28^^
And every person with adobe player 9,0,124, its ok for the two files.
So i try to find something to do with that... (change swf object, detection of flash player...) I really dont know^^

But thanks for your helping all.:thanks:

One option is to encode in zones (lower quant for that segment); another option is to try adjusting AQ higher instead of using CQM

1st, that matrix is not mine. drop it since AQ is enabled by default and results with custom matrices are unpredictable.
2nd, restore deblocking settings to the default (0:0) or a sane value.
