MeGUI: General Questions and Troubleshooting Thread

[Sharktooth]

check the CPU load before encoding and during encoding.
the first should be close to 0 the second should be 100%.

[rhys87]

yeah its at 98% when encoding, i have restarted comp as well, really starting to confusing me.

[foxyshadis]

Is this 1080i? That requires way more power than dvd-res.

[rhys87]

here is the log

--pass 1 --bitrate 1000 --stats "C:\Program Files\WebScheduler\capture\rhys2.stats" --bframes 3 --b-pyramid --direct auto --filter -2,-1 --subme 1 --analyse none --me dia --progress --no-psnr --output NUL "C:\Program Files\WebScheduler\capture\rhys2.avs"
successfully started encoding

the first pass only goes at about 8-9fps when with StaxRip goes at about 25-30fps, does deinterlacing decrease the speed that much?

[foxyshadis]

LanczosResize(512,288)

Wait, why not just toss a field away? EEDI2+Tdeint is a performance hog, you could just use SeparateFields().SelectEven().LanczosResize(512,288) and get practically the exact same result, since you're halving the vertical resolution anyway.

[rhys87]

thanks alot, foxyshadis :) problem fixed.

[Xin-Hong]

Hi,

I discover MeGUI with the x264 VideoProfiles, very usefull for noobs like me :p so I wonder if there is VideoProfiles for XviD

[foxyshadis]

Teegedeck is working on them, iirc.

[markrb]

Should I still be getting the warning popup about the bitrate calc not being updated with the latest version of Megui?
I have been using autoupdate since 2148 so maybe I need something that autoupdate doesn't update if this has been fixed?

I remember seeing something about the warning was going to be removed in an earlier thread.

I am running 2155, currently.

Mark

[berrinam]

I thought I had fixed it, but it still seems to be quite buggy, so the warning message does apply.

[Carpo]

no so much buggy - as completly broke :(

[shon3i]

No bitrate calculator working fine just need little tweaking

[Carpo]

2155 bitrate calc dont work here - 5587 for a single cd backup - bit much me thinks ;)

on a diff topic if i wanted to do .ts to hd-dvd (well that qual anyway prob be a 2 cd poss 1/2 dvd) is it a simple step of selecting size (original is 1920x1080i) my pc can do 1280x720 nicely, and selcting the hd-dvd profile from within megui or is there other things i need to concider, im still new to this area of backup so please excuse and old n00b ;)

Here are my experiences, such as they are:

1. If your TS is a movie, proceed much as normal. One catch: DGIndex often refuses to read TS files, it complains about missing "PIDs" whatever those are. So I process the .ts to .mpg with a program called "HDTV to MPEG" first, and run DGIndex on the results. Then AviSynth can chew the D2V file and serve it to MeGUI.

2. If it's a TV show with multiple sections including interlaced video, telecined film, archive footage rezzed up to 1080 etc, MeGUI seems to have a hard time choosing a deinterlacer that gives decent results. It's usually better to write your own Avisynth script using DirectShowSource() to get the video stream into the encoder and let DirectShow deinterlace it. [The docs say AviSynth tries to disable DirectShow deinterlacing, but fortunately I've never seen it succeed.]

3. On my usual settings, I get about 7fps for 720x576 PAL DVD backups done in single pass constant quality mode and I don't worry about how many files fit to a DVD. For 1080p/24 I want one movie per DVD so I have to do 2 pass, and I get about 1.2 to 1.4fps on each pass. It takes me 3 or 4 days to encode a movie (A64 X2 3800+). If I didn't like the ColorMatrix() filter in Avisynth so much (my backups look better than the originals), I'd just burn the TS files to two or three DVDs. Some time I'll check out how Xvid does with one HD movie on a DVD9.

4. Many a transport stream has a negative audio delay and a few hundred bytes of junk on the front of the sound. MeGUI may refuse to open these for encode using its standard NicAc3Source filters. MkvMerge doesn't particularly like muxing them straight back onto the encoded video without audio compression, either. DirectShowSource will get the sound into the encoder, and then the encode will synch/mux OK.

[MajinNinja]

Hi All,
I'm using MeGui v0.2.3.2116, DGMPGDec v1.4.6, TIVTC v1 RC4 and I'm having the following problem. Whenever I attempt to perform the deinterlace analysis an error window pops up stating that TIVTC.dll cannot be found and that 'tfm' is not a recognised command. I have TIVTC.dll in my avisynth dir and using it in scripts without issue. Any ideas what may be happening?

Cheers :)

[Carpo]

sounds like it might be a right pain in the arse, although latest dgindex (1.4.7b12) had no issues with it

guess its a case of trial and error :) to see what resssults will look like

thanks for the advice

edit: found NullPacketStripper_v013beta it seems to join the ts files together ok with no apparent sync issues :)

[wacco]

Excuse me, but how do i create profiles for the one click encoder? i need to encode dvd rip>avi. Megui says i need to select audio/video profiles, but there dont seem to be any of them?

[berrinam]

Get a new version of MeGUI from http://x264.nl and it should be clear.

[sillKotscha]

just a question...

for minimal denoising of a video_clip shouldn't Undot() be replaced by RemoveGrain()?

advantage (IMHO):

- RemoveGrain(mode=1) is identical with trbarry's Undot (even the speed of the SSE version is nearly identical to that of Undot, but the SSE2 and especially the SSE3 versions are significantly faster)... = from the readme
- the denoising algo is considered to be more complex

what do you think...

[sillKotscha]

when using the avisynth script creator I have noticed a difference between d2v source and directshow source...

my guess is that it could be an avisynth failure because detection via d2v source is correct... see attached pictures.

[Doom9]

I have noticed a difference between d2v source and directshow source... And what would the difference be?

[sillKotscha]

have a closer look at the pictures - hint: input DAR and as a result the suggested resolution...

Edit: it is provided that the same source (vob) is used

1. loaded after d2v was created
2. loaded without d2v creation -> thus directshowsource is used...

[Doom9]

Your second image never loaded at work.. so there was no "this instead of this" effect for me.
Is the resolution of your VOB 720x576? That would explain the 1.5 DAR. The thing is.. in this scenario you'll never have a 16:9 DAR.. DirectShow doesn't know that.. could be that DAR flags are ignored, could be that they are taken into account. If you want reliable info, only DGIndex can provide that.

[sillKotscha]

Your second image never loaded at work.. so there was no "this instead of this" effect for me.

I've realized that too... sometimes the 2nd image won't load...

Is the resolution of your VOB 720x576? That would explain the 1.5 DAR.

no, it is 720x480 4:3 NTSC, but nevertheless after your explanation it is clear that directshowsource doesn't take DAR into account...

it was just a quick and dirty "hey, I have found out something" but didn't thought twice about it - sorry!

[berrinam]

When someone gets around to adding MediaInfoLib support to MeGUI, that might be solved, because MediaInfoLib can hopefully detect the AR of files

[cc979]

i've just figured out, why my .mp4 input in the avs script was not working - i've found that ffdshow 'use overlay mixer/allow output formay changes during playback' has to be on indeterminate state.

is that normal? or some kinda strange bug with megui/avisynth

[wacco]

Ive got the latest MeGui, and I can encode .avi files with sound like a dream using script creator. However, I dont understand how to get a DVD (I have the vob and ifo files from DVD decrypter) and convert the rip to avi/xvid? I cant seem to do it rightly even when using One Click converter. Please help.

[BigDid]

Hi,

Regarding Removegrain(mode=1), Kassandro has corrected a bug present in undot(), infos here: http://forum.doom9.org/showthread.php?p=533526#post533526

Also be sure to use latest version from: http://www.removegrain.de.tf/ (was Pre 1.0 a few weeks ago)

If you want more than minimal denoising, give a try to mode=5 (or 6), I find it more conservative than mode=2. For stronger denoising I have switched from mode=7 or higher to Degrainmedian(mode=3,5) or less.

[Doom9]

@wacco: There's a sticky megui guide. If that ain't enough, you gotta be way more specific as to what you don't get. Just thing on how you would explain things to your mother.. that's exactly how you should approach any such problem... asume people know nothing, just have the software and you have to guide them through everything.

[Morte66]

Can anyone tell me how to feed raw YUV files into MeGUI for encoding? I downloaded several GB of samples (not copyright) and I would like to do some experimental encoding. I guess the usual DGIndex thing is not on.

I thought perhaps I could find a DirectShow codec then use DirectShowSource() in AviSynth. But I can't get them to play in any ZoomPlayer/WMP/VLC, despite having a whole bunch of codecs with "YUV" in the name. I can play them very slowly using a program called YUV viewer, and the video data is fine. I just can't get it to MeGUI.

My Google-Fu has failed me this day. All help, hints, or idiot-proof walkthroughs appreciated.

[berrinam]

I don't know how to input raw yuv into MeGUI, but using x264.exe by itself, it will accept such files, as long as you give it the dimensions.

[Morte66]

There's a start. :) Thanks, I'll look up the command syntax.

I'm kind of hoping to do this with various encoders/formats and see what happens, including a couple of h264 profiles and MPEG2 at BluRay bitrates. But one step at a time...

[Morte66]

Wow! x264 looks fantastic when you aren't starting from MPEG2.

[berrinam]

Can you send me a link to where you got these YUV files?

Cool, now I can pad them to 1088 lines and string them together to get scene changes and so on. Thanks, Sharktooth.

Ok, I've been trying to do this for some weeks now, without success. Now I have the time to write detailed here on forums. Sorry bad english by the way :o .

Ok, I have a ripped DVD ripped in IFO mode using DVD Decrypter. I want to convert the rip into a avi file, using Xvid as the codec. I've heard the easiest way is using the one click encoder, but I cant get this to work (problem with profiles, I cant even set them up).

I select output directory, input vob file, but no result. It just says I need to select audio and video profiles? Look at screenshot 5 - I cant select audio profile, there are no audio profiles there :scared: .

I tried one click profile setup, but I cant seem to set up one. Help.

It looks to me like you need to make a preset or download a preset. Do you want to use MP3? If so, in the main MeGui screen, click codec in the audio "box" and select mp3. Then press the button next to it saying "CONFIG". Set your parameters here (defaults are ok, maybe you want to set ABR instead of CBR) and then click the "new" button near the bottom of the window. Type in a name for your new preset!!

This should allow you to pick the settings you just saved when you use the one click encoder. I just tried this and it worked great for me!!

[wacco]

Thanks, i manage to start now, but then i get these errors. The one to the right first.

[Doom9]

And the log would be? It almost sounds like your dgindex is somehow preconfigured to apply force film... auto force film in megui only comes after dgindex has been run and there's no way to configure force film from the commandline (at least last time I checked). And megui's automatic source type recognition comes even after that

[berrinam]

@wacco: You're on a very old version of MeGUI. Grab a new one from http://x264.nl

[Sharktooth]

this may be generally interesting: http://forum.doom9.org/showthread.php?p=836694#post836694
aud-x decoder doesnt actually work with avisynth directshowsource().
since Aud-X can decode normal mp3, ac3 and pcm files, it can severely cripple the audio functionalities of MeGUI.
So, before encoding with MeGUI be sure to disable the Aud-X decoder.

Wich audio codec do You select?

MP3 CBR. Its possible that Ive forgot to do something, I'm not sure. Sorry for being so bad at this :( .

[wacco]

I have recorded a video with my actions. I cant undertstand why I cant output in AVI. The result I get from my actions in the video is a mp4 file.

http://www.youtube.com/watch?v=CruYFCw-b44

Please take a look at it. In the one click encoder, only MP4 is there as an option.

[berrinam]

Got it. You probably should take a look at the advanced options, which you can get by checking the 'advanced options' checkbox. You can choose your format in one of them.

[wacco]

Thank you mister!
It looks like its working to output avi now :D . Thanks a lot! Im happy now ^^ .

[M.H.A.Q.S.]

I recently started testing MeGUI and StaxRip along with x264gui. There is one problem that i had with the three of them while I encode movies.

I want to encode a video file and I select the PSP profile and the output type to be .mp4 and I don't want to encode the audio and I select the codec to be x264.

The conversion is done fine by all three but the output does not run on any media player, no matter what I do. I have all the codecs correctly installed and until I select the codec to be any other than x264, it won't work.

Is there any problem on my end or is it the x264 codec?

the AVI, MKV and RAW output is fine when using DivX, XVid etc. But any encoding done with x264 won't work.
