StaxRip and latest MediaInfo both state the source is interlaced, and the Megui source analyzer says it's progressive ? :confused:

MediaInfo (StaxRip uses MediaInfo probably) is a library which is able to parse only the headers/footers from files, whereas the Analyzer in the AVS Creator parses some parts from the whole stream. That's why you can have some differences, especially with this kind of information (interlaced/progressive).

This is not accurate all the time. Depends on the source type...

I'm interested in knowing if MeGUI can do a "null" encoding job. I want to join two H264 videos in MKVs together, but one of them was encoded with a custom quantization matrix, making a straightforward join impossible. Can anyone tell me if it's possible to run the MKV through MeGUI in such a way that it does nothing to the video stream but removes the CQM information from it?
I know I can reencode the video, but I prefer not to compromise its quality. Not to mention, it would take longer than the alternatives.
Are there any programs that would let me read or remove the CQM information without needing to reencode the video? If I can remove it, great. If I can read it, I can use it to encode the other MKV using it.
I would be most grateful for any assistance given.

Sharktooth
25th March 2009, 15:43
no. you cant simply remove the CQM information and pretend to decode the video correctly...

DGA Project Creator is not a tool to transcode files. It's mainly an indexer for AVC streams and a tool which is able to extract audio streams from your input.

With it, you create a dga file to use it afterward via an avisynth script for example.

In other words it works like d2v for mpeg2 streams, but with avc streams instead? That's what I thought but I can't get it to work at all. I thought I would use it to create a DGA file and then open it to create an avisynth file, but I can't get it to run, and am not sure how to diagnose the problem. What underlying program is the DGA creator using?

Correct...

DGAvcIndex or DGAvcIndexNV...both work.

DGAvcIndex or DGAvcIndexNV...both work.

I couldn't find either of these programs in the C:\Program Files\megui\ directory or subdirectories.

I installed meGUI before the DGA Creator was available as an option. Perhaps the automatic updates didn't install these apps? Does the latest installer include these apps? Thanks.

I couldn't find either of these programs in the C:\Program Files\megui\ directory or subdirectories.

Neither is included. DGAVCIndex is a standalone freeware program that does for H.264 what DGIndex does for MPEG-2. DGAVCIndexNV is like DGAVCIndex, but does hardware deinterlacing on many recent Nvidia chips and requires a one-time license fee that also unlocks DGMPGDecNV (MPEG-2) and DGVC1DecNV (VC-1).

Thanks for clearing that up. I have a 9600GT so it looks like I can use the nVidia version. I've downloaded it, but I'm not sure how to install it so meGUI can use it properly. Please advise. (Thanks again for the help!)

26th March 2009, 04:46
Use it to make a .dga file, open that with MeGUI's AVS Script Creator. Note that if you elect to deinterlace in the DGx tab of the creator you don't then need to deinterlace in the normal way. None of this will work until you pay the license fee for DGAVCIndexNV through neuron2's site, of course.

That's too bad. Then, is there any way to read the CQM info from one video so that I can use it to encode another? The one program that I could find to do this was avinaptic, but it gave incomplete information so I need something else.

QuadraQ
27th March 2009, 03:04
OK I got my license file from neuron2 for the nVidia versions of the DG programs. Set up my paths in meGUI to point to them. I run the DGA Creator utility in meGUI and it creates a dga file successfully as far as I can tell. I then load the dga file using the AVS Script Creator and get this error:

---------------------------
AviSynth error
---------------------------
AviSynth script error:

Script error: there is no function named "AVCSource"
---------------------------
OK

Am I running the wrong version of avisynth? I have v2.5.8 installed. Please advise (and thank you for your help and patience).

When creating a raw *.264 file from a *.m2ts file I press the Enqueue button and it creates job1 (stats file) and job2 (264 file).
Then pressing the "queue analysis pass" creates job3 (avc).
Job3 , when running, log says encoding started, but is this really an encode or is it just playing/analysing the file (it appears to play in real time so that a 1hr45' min movie takes that long to analyise.

So, my question is, is that analysis pass really necessary ? Just adding all that time to the project or can I skip it safely. It appears to me that any errors in the en/re code would show up in the log.

1/ Put DGAvcDecodeNV.dll in your avisynth plugins folder.

Depends on what you want to do exactly...

OK great that works - thanks for clearing that up. I'm not sure what to do next though. When I load the AVS Creator on the second tab, when I click analyze the progress bar is seems stuck and it doesn't appear to be working. (I have the CuVIDServer running in the background.) My ultimate goal is to save the script and then open it for encoding in HCenc to make a DVD compliant m2v file.

I tried "guessing" the values (Film - actually it's 23.976 so I'm certain of this one) and Top field first and saving the avs file. I can open it in windows media player, but HCenc just stays stuck when I try to encode (kind of like the analyze problem). Sorry for all the questions - this is all new to me.

Hi,

Is it normal that DGIndex is hidden when using the D2V creator (and please, can we have an option to at least show it, even minimized would be great).

Also, while DGIndex is running the progress windows stays empty, and doesn't update at all. Is that some fault at my side, or is this currently normal ?

Thanks in advance !

Is it normal that DGIndex is hidden when using the D2V creatorunless they changed that part of the code, yes. Why would you need to see something basically uninteresting?
Also, while DGIndex is running the progress windows stays empty, and doesn't update at all. Is that some fault at my side, or is this currently normal ?DGIndex does not provide any kind of progress indicator via commandline so yes it isnormal.

Well, after my joyful StaxRip period, I STILL haven't been able to get a MeGUI encoding without errors or other crashes.

After the DGIndex, and the Analyse for interlaced material, MEGUI produced the following VTS_01_1.avs file :
DGDecode_mpeg2source("N:\Mijn andere DVD films\Lili & Marleen (Seizoen 5)\ShrinkDVD1\VIDEO_TS\VTS_01_1.d2v", info=3)
ColorMatrix(hints=true, interlaced=true, threads=0)
tfm(order=1).tdecimate(hybrid=3)
crop( 14, 0, -4, 0)
#resize
#denoise

unfortunately, whenever the x264 encoding started, it errored out immediately with the following log :

Please, what went wrong *again*.....:confused:

EDIT: Well, found the answer on page 195, it was due to the cropping resulting in a "Avisynth error: YV12 images for output must have a width divisible by 4 (use crop)!"

I really thought MeGUI was smarter than that, sorry for sounding rude BTW.

You just need to either check the Anamorphic encoding box or check the suggest resolution(mod 16) and your errors will go away.

I don't remember having these problems with StaxRip, it had a smartcrop, meaning it didn't crop to mod16, it could even crop to mod2, and x264 happily encoded the content.

And you seriously think StaxRip has some magic wand that makes AviSynth behave differently? I love it when people blame anybody but themselves for their own faults - and constructive criticism is something that you apparently never picked up. You know, a constructive person would open the same source in both programs, crop the same way, then compare the output scripts - just an idea to actually get to the bottom of why it works in one software and not in another and maybe, just maybe you'll see that Staxrip does a tiny bit more behind the scenes than you might think - after all it uses the same encoder and same avisynth so it has to deal with the same limitations as every other GUI.

For some reason, this last x264 update (1128) makes my files go way too big when encoding with CRF.
Everything else is fine, but using CRF 18 on a 3 minutes 640x352 video, with no fast movement at all and kinda dark, it goes 180 MB!
I checked everything else and it works flawlessly, just the CRF seems broken. Can you check it, please, and if possible, correct x264 on the autoupdate?

The resulting video has an ugly glitch.

Then I demuxed the m2ts file with a different tool and tried remuxing the mkv file that MeGUI had created. Both tests worked fine so I guess that the mkv muxer in MeGUI caused the problem.

wtf ??? eac3to (the tool used to demux streams in the HD Streams Extractor) uses the haali filter to write matroska file, not mkvtoolnix.


my guess is either the FFVideoSource (did you try DirectShowSource instead ?) or the Haali Writer the culprit...

me7
31st March 2009, 14:35
The problem does not occour with DirectShowSource, but FFVideoSource works fine when I demux the same episode with tsMuxeR or when I remux the matroska file created by MeGUI with mkvtoolnix. Even stranger is that one episode,which I had demuxed withMeGUI twice, worked fine once but had the same error the other time.
Seems like FFVideoSource does not like the mkv files created by the haali filter. I'll post this in the eac3to thread.

the new x264 revision i put today on the auto-update should work on older CPU too.

Yep, most certainly did.

Thanks.

Are video dimensions, i.e. 1920x1080 vs 1280x720, not a variable in the bitrate calculator? I would have assumed that downsizing a 1920x1080 to 1280x720 using the same target size would result in 1280x720 having a larger bitrate. I'm finding this not to be the case with MeGUI bitrate calculator. Am I doing something wrong?

why? bitrate = bits / second. resolution is not part of that calculation...

Hello everyone, I was wondering if I could get some tips for compression. Im trying to get some ultra small and high quality mp4 files using megui for use in a wowza streaming server. Im using the insane quality preset with a low bitrate. They seem to stream ok through the wowza server but there is considerable lag when seeking and loading a new video. VP6 FLV videos are much much better at this. Also I fear this is hitting my server hard performance wise. Could anyone give me advice for compressing to this environment?

Thanks for everything

So if the video bitrate is the same in 1920x1080 vs 1280x720 for the same output file size why would you resize a Blu-ray Disc to 1280x720 to burn to a DVD9?

Bitrate = bits / second. ;)

The average bitrate of the whole movie is the filesize divided by the playing time. So it does not depend on the frame dimensions.

But of course there is a related value, a kind of "specific bitrate", which was already displayed in the "ancient" GordianKnot converter: bits per pixel and frame (bppf). This is a soft limiting factor.

The less bitrate you can spend per pixel and frame, the worse the video may look. If you have less pixels per frame, you can spend more bitrate per pixel, maintaining the same average bitrate over the whole movie. Also you will try to avoid double-framerate video (e.g. 50p does exist, and is broadcasted, e.g. by Austrian TV), because twice the framerate leaves only half the bitrate per pixel and frame.

Example:

4.7 GiB * 8 b/B : 1280 : 720 : 2 h : 60 min/h : 60 s/min : 25 f/s ~ 0.23 bppf => probably enough for good quality with AVC

4.7 GiB * 8 b/B : 1920 : 1080 : 2 h : 60 min/h : 60 s/min : 25 f/s ~ 0.10 bppf => probably just crap even with AVC

And I forgot to keep reserve for the audio.

yeah... that typo has a long story... (in italian the * character is read "per"... so my twisted brain unconsciously suggested me to abbreviate "bits per second" with "bits*second"...)

however, BPF is not good coz it doesnt take source compressibility into consideration.
so, all in all, you will always end up in needing a compression test to choose a minimum bitrate.

UPDATE: THIS POST IS WRONG, NOD32 is NOT the issue!

Greetings everyone,

While not explicitly a bug report to Megui, I thought I should let people know this in case they have problems too:

I've been having problems with x264.exe mysteriously crashing(yes, while using megui). I use vista x64, with core2 quads and core i7's overclocked to the max. As a function of my multithreaded environment, I also make heavy use of avisynth MT, the multithreaded extension (yeah, I know how buggy this is...) (also, yes my boxes are stable, as I have thoroughly stress tested them, and I get x264 crashes when I was testing at stock speeds)

So, basically, my x264 encodes through megui were crashing almost every time, at totally random places. I was unable to get any error or crash info from megui or x264. Nothing, just a generic windows error saying, "X264 has crashed..."

I was coming to wits end, when, during a google search, I decided I might try suspecting my anti-virus software as an issue. I use NOD32 version 4 (the latest one). I placed an exception on the /tools/x264 directory, and added an extension exception on the extensions .stats .stats.temp .x264 and .264. I have also gained an extra 2 to 4 fps on my encodes by doing this too.

I believe I may have solved my issue, and I'll let everyone know if I'm still having problems.

UPDATE: THIS POST IS WRONG, NOD32 is NOT the issue!
See the posting two down...

good to know. so NOD32 officially gets a place on my softwares black list... :D
well... not that i need an antivirus though...

Just an update to my above post, NOD32 is not the issue :(

I'm testing some new hypothesis, but basically i think huffyuv is getting just a bit too old now, especially since the core i7's have 8 logical cores...
