MeGUI: General Questions and Troubleshooting Thread

[rishid]

I am trying to convert an h264 Elementary stream to Xvid using megui. It has worked many times, but for some reason on this one file it keeps crashing at 2.3%. It gives an error about xvid_encraw.exe.

Using the DGAVCDecode.dll filter.

Running the latest updates on Windows XP.

Here is my Avi Synth script that I used to import into megui.

LoadPlugin("DGAVCDecode.dll")

AVCSource("s-tbu_Track1.dga")

[mroz]

An obvious 1st question is what's the full error?

[rishid]

MeGUI just crashes with a standard Microsoft looking error on xvid_encraw.exe stopped working. I may have fixed it, I went to an older version ( beta 12) of DGAVC and it seems to be working past 2.3%. If I run into any more problems I will post some more details, but it seems related to DGAVC and not MeGui.

[Sharktooth]

ok, thanx. please also inform neuron2 of your findings about dgavcdec

Hi, i demuxed my HDDVD, and got a *.mpv file which i used in my *.avs file.

When i watch the *.mpv with powerdvd i can watch the whole movie. But when i load the avs into Megui, only about 1h06 are diplayed instead of the whole 1h49min !?


Some1 knows where this error comes from, or what i made wrong?

[Sharktooth]

play the .avs thru a directshow media player (WMP, MPC, whatever...) and see if the duration is right.
if it isnt, the problem is in the avisynth script.

[Penecho]

Ok, it is also too short when i play the *.avs into MPC!

My avs file looks like this:


directshowsource("D:\feature1.mpv",fps=23.976,audio=false,seekzero=false,seek=true)
Converttoyv12()
Spline36Resize(1920,1080)
crop(0,144,1920,802)



I also tried

directshowsource("Z:\feature_MERGED.VC-1.stream.0.mpv",fps=23.976,audio=false,seekzero=false,seek=true).trim(0, 171955)
Converttoyv12()
Spline36Resize(1920,1080)
crop(0,144,1920,802)

what does M-in-5 decimation mean in the source type - in all the backups i have done i have never see this source type before

TDecimate(cycleR=1) - is what it says in the avs - theres no problem with the back up - im just curious :)

Hi, I managed to extract the video of an flv file, you know the ones that you get fron youtube, using the avisynth script editor I extracted the video but I dont know how can i extract the audio, can someone please help me out with these?

Thanks in advance

Make a separate .avs for the audio which is the same as the one for the video except with audio=true, video=false and use it in place of your original audio material.

[Penecho]

play the .avs thru a directshow media player (WMP, MPC, whatever...) and see if the duration is right.
if it isnt, the problem is in the avisynth script.

Now i made a graph file first and than loaded iht graph file into the avs. And i used the .trim(0, frames) option.

In the MeGui preview window i only see a short part from the movie, but when i start bitratecalculator, he has the right time in it. So i guess its correct now?

Or should the preview window show the complete movie!?


Cu

[Sharktooth]

the megui preview window shows what avisynth sends to megui.
PLAY THE .AVS THRU A DIRECTSHOW MEDIA PLAYER... and check if it is ok.

[Penecho]

Ok, still does not work :(


directshowsource("C:\graphfile.grf",fps=23.976,audio=false,seekzero=false,seek=true)
Converttoyv12()
Spline36Resize(1280,720)
crop(0,10,1280,694)


when i use that, the complete movie is in, but after the end credits there is about 1/3 of the runtime, additional grey video...

When i use:


directshowsource("C:\graphfile.grf",fps=23.976,audio=false,seekzero=false,seek=true).trim(0, 157181)
Converttoyv12()
Spline36Resize(1280,720)
crop(0,10,1280,694)


runtime is correct but only about 10mins of the movie wich repeat themselves over and over agasin, the whole runtime...

In the grf i connected the output pin from my *.mpv file to the input pin of the Elecard MPEG Demultiplexer and the output pin from that to the input pin of Sonic Cinemaster Video Decoder...

Any1 seeing what i di wrong?



Cu

[Warpman]

try this

directshowsource("C:\graphfile.grf",fps=23.976,audio=false,seekzero=true,seek=false).trim(0, 157181)
Converttoyv12()
Spline36Resize(1280,720)
crop(0,10,1280,694)

and make sure you have the lastest avisynth installed and you should crop before you resize...

[Carpo]

i know this has prob been asked before and i did do a search but it brought up a long list of threads with many many pages on them, and reading through them al would have taken an age, but here goes

does an anti virus tool like est nod32 (for example) which uses real time scanning affect encoding in any way? also would it affect burning discs

if so would it be wise to disable the av protection only when doing such tasks

[mroz]

Virus scanning shouldn't hurt encoding other than slowing it slightly - unless something is seriously broken.

Same answer for burning, unless your hardware is only borderline capable of writing the disks anyway. Suck it & see.

Treat video encoding as for any cpu intensive task.

[Carpo]

i ran a test encode over night - didnt seem to affect it in anyway have NOD3 on :) , pc is an amd64 x2 so im guessing after the encode i should be ok on the burning side :)

[St Devious]

can encoding be paused in Megui ?

[rack04]

Are there any plans to add E-AC3 support using ffmpeg?

[Kurtnoise]

If there is a plan for E-AC3 support, it won't be with FFmpeg but more with avisynth filters...

[Kurtnoise]

can encoding be paused in Megui ?
it has been disabled but I might be wrong...

[gino25]

is it possible (with medui) to demuxe video and audio?

Ex: if i have an avi file (DIVX + MP3), is it possible to extract mp3 sound?

If no, do wxist some program that do this?

Sorry for my bad english

[Sharktooth]

no, megui does not have a demux function.
to demux avi files you can use avidemux or virtualdub
next time :search:

[Atak_Snajpera]

Demuxing can be done via h264tsto + registered dump.ax
eg: h264tsto input.avi -demux -audioonly

It would be peace of cake to implement it in MeGUI.

[rack04]

When I try to load the following AVS file into the "AviSynth script creator" I get an Directshow error message saying "Unable to render file. You probably don't have the correct filters installed". I'm trying to use the crop and resise function so I can add this information to the AVS file.

DirectShowSource("C:\Personal\Videos\Matrix.grf", fps=23.976, framecount=115796, audio=false)

Matrix.grf consists of the following graph:

http://i11.photobucket.com/albums/a199/rack04/filter.jpg

The AVS file will play using Media Player Classic:

http://i11.photobucket.com/albums/a199/rack04/mpc.jpg

Any idea what going wrong?

[Sharktooth]

try setting FFDShow to decode WMV

[rack04]

try setting FFDShow to decode WMV

libavcodec or wmv9?

[Sharktooth]

libavcodec

[rack04]

The results are the same.

I have a question,

Do the "Turbo" setting in MeGUI x264 options have a significant impact on the quality of the output file?

I'm talking about a 720p encode @ 4400 kBps. I noticed that on my snail(system) the first as well as second pass take 36 hours each without the turbo option enabled.

On the other hand if i enable the turbo option, the first pass get over in less than 4 hours. I'm using HQ insane profile with custom quantization matrix.

So does the turbo first pass really reduce quality of second pass output at 4400kBps?

this setting is to optimize the speed. So, there is none impact on the quality.

[check]

compare the output log details, and perform your own visual inspection. The change depends on the input reasonably highly in my experience.

id like to know how i can cut a part of a mp4? like the last 10 seconds of a video , using mEGUI .. thanks in advance.

Assuming you mean without reencoding, MeGUI doesn't provide that functionality. Try Yamb (http://yamb.unite-video.com/index.html).

[Sharktooth]

or avidemux

[mroz]

/Googles

Oh yeah - silly me thinking avidemux would only cut avis. Will have to have a closer look too; cheers.

[fleon]

Hi people please help me out with three questions, I dont know how can I cut the audio already extracted from a video file to match the video(wich I can cut it easily with the AVS cutter) I imagine that I can use the audio cutter but I put the input file and then it ask me for a cut file and i dont know how I can generate that cut file,

and the other questions or more like an explanation is that I have noticed that there are several resizers in the avisynth script editor on the part of filters and I dont know what to use, I just use Bicubic neutral but I wanna know each one so I can take advantage of the other ones.

And last one is there some kind of rule of bitrate for types of movies, and types of videos, types of anime , etc, for the PD-PSP profile that I can use? because I most of the time use 450, and I think is too much but as i dont know so i use that, the last movie that i encoded was Final Fantasy VII advent children and I used 450.

Thanks

[Willows_Thoughts]

Ok... I feel like and idiot for asking but I am having such a dumb problem with MeGUI and I can't figure it out!

Anytime I try to open a file in the AviSynth Script Creator whether is be .AVI or MPEG2 files it always gives me the error "Unable to render file. You probably don't have the correct filters installed.

I have downloaded and installed CCCP but still no luck with opening any files. I uninstalled it but will reinstall if there is something I missed.

I already had FFDshow installed, XVID, a h.264 decoder but I just am not able to open anything...

Any help would be appreciated.

EDIT:
I do try to create a D2V file for MPEG2

When I try to creat a D2V Project I load the VOB but there is never and option "enqueue" it always say "queue"

Test test test!

Anytime I try to open a file in the AviSynth Script Creator whether is be .AVI or MPEG2 files it always gives me the error "Unable to render file. You probably don't have the correct filters installed.Make a text file and put inside it directshowsource("path\to\one\of\the\nonloading\files.avi"). Save it as an avs. Does it open with WMP? If not, what is the error message?

[Willows_Thoughts]

I have spent almost two days trying to figure out what was wrong.

The problem was that I did not run MeGUI as an administrator... I was unaware you actually had to do it manually. After I ran it as one it allowed me to update everything and allowed me to input all of the files that would not previously load.

[Carpo]

do i need .net 3.5 if im using megui on XP SP2 or is it just required if your using vista ?

[Ravenlord]

Hey, i have a problem with megui, i get an error

video returned: directshowsource: renderfile, the filter graph manager wont talk to me

audio returned: directshowsource: timeout waiting for graph to start


oh and... Its important..

[fleon]

Hi i have a problem with megui, I wanna convert a personal own movie to x264 on the PD-PSP profile, megui(the avisynth script editor) and gspot detects that the movie is 29.970 FPS, but the problem is when I use the avs cutter that it changes the fps to 23.976 and I dont want that because then when I try tu cut the audio with staxrip it detects the 29.970 FPS of the movie so it is a big problem until I sync the video and the audio to fit perfectly, i do that because I dont know how to use the audio cutter, and still it will be great if you guys help me out with for keeping the original FPS not the one that the avs cutter use.

I think this happens because on gspot it also detects that the Pic/s is 23.976 and the Frame/s is 29.970 so maybe the avs cutter picks the Pic/s inestead of the Frame/s

[airedale]

I am running into an issue with a conversion to an XviD file.

The error I get is:

Error message for your reference: AVISource: couldn't locate a decompressor for fourcc FFVH

I went into the AVS file and changed it from AVISource to directshowSource. This seems to have gotten me further. The encode isn't completely finished though.

So my question is, why am I getting this error and what is the big difference between avisource and directshowsource?

Thanks!

[check]

ravenlord, what happens if you open the avs in WiMP?

fleon, most likely the video is telecined. That means your original file is 29.970 interlaced, but you should encode it as 23.976 progressive.

airedale, It means the AVI decoder couldn't find a vfw decoder for that codec. Enable it in ffdshow vfw config -> decoder -> codecs -> set the FFVH entry to 'libavcodec'

[airedale]

@check -

Thanks so much! I am suprised more people haven't run into this problem. I search and searched before posting.

[fleon]

fleon, most likely the video is telecined. That means your original file is 29.970 interlaced, but you should encode it as 23.976 progressive.

Thanks, but how can I cut the audio in megui to match the video that i can easily cut in the avs cutter?, or in staxrip how can I change the fps of a movie?

[mroz]

fleon: in avscutter after writing the cuts into the avs script, also click on 'save cuts to file'. Within Megui's main window where you specify the audio input, load up the saved cuts file.

[Unrealbr]

Oh well, today i had my first issue with megui and aint beeing able to solve it. Its the folowing: Today i started megui to encode another file and setup it correctly, checked everything and queued, then when i pressed start windows vista came with an magical x264.exe has stopped working window and closed the program. I got my hands on windows log and here is the log:

I really dont know what to do, i've already reinstalled my codecs and megui from scratch and keep getting this error.

PS: error c0000005 as far as i've googled turns back as memory error but i ran memtest on all my 4gb of ram and got 0 problems. What could the problem be? HEEEEEEEELP!!!
