MeGUI: General Questions and Troubleshooting Thread

[mario87]

Someone delete my post? It's impolite :angry:
My post is not spam
I'm not a spamer !
I've just joined this forum for a few days and I only ask what I don't know. I don't find the answer in FAQs so I want to ask for helping. Is it difficult to answer my question?
All right, maybe my question is rather difficult to understand because my English is bad but instead of deleting my reply, you should explain why :mad:

[maohsama]

Since the recent version, whenever I choose a file in the AviSynth script creator, a dialog pops up asking whether I want to use the One-Click, File Indexer or continue with this method. How can I disable this annoying dialog? I never choose those two other options, because One-Click always messes up my encoding(missing sounnd or missing subtitle) and file indexer is not necessary.

I encoded a video to Xvid and I found out that MeGui is still using Xvid version 1.2.1 and we are at version 1.3.2 already.

Is anyone aware of this?

its been a long time :)
and am happy to see master Zathor still helping the community. :) kudos bro !!!
ok well till date i have not been able to convert a dts or ac3 5.1 audio in a aac 5.1 format , no matter what i do ,
i tried extracting the audios , not using directshow and stuff , but 90% of the cases there is error at the end of the encoding process or it wont start, or if at all with this is that settings it finishes it is always 2 channel.

i wonder if i need to make some changes to klite codec pack ,
or if there is ant simple smallish pgm which can do that for me.

god bless
regards

[darkside40]

Take eac3to, the Arcsoft DTS Codec and NeroAACEnc. Note you need a patched checktivate.dll to register the Arcsoft Codec. I use this combo since months and have no Problem with it.

I am encoding to XviD AVI, I have splitting off but it keeps spliting my video into 2 files? Anyone know how I can stop it from splitting them? I am using the latest version of MeGUI the update from last night.

[LigH]

Did you set up a target size of more than 2 GB? Or ... what are the sizes of the segments exactly, in relation to the wanted result?

[Chudz]

I set a custom size to 3.5GB and setting splitting to "No Splitting" It seems to split at 2GB

[Music Fan]

AVI v1.0 is limited to 2 Go, that's perhaps the explanation.

[Chudz]

Is there a better for version of XviD AVI I should be using or somthing then?

[Music Fan]

For Xvid, you should maybe encode with Virtual Dub.
If you prefer MeGui because it creates avisynth scripts, you could maybe avoid the encoding step in MeGui and use this script with Virtual Dub.
But I don't know if it's possible.

Try to demux the DTS file from your MKV container.

Please post your log!
If it splits the file during the mux try switching the device type in the AVI muxer to PC. The default setting will split at 2GB as standalone players most of the time have problems with avi files > 2GB.

[kartikoli]

I have 2 problems

1- How do i use filters while creating avisynth script .. i can load .dll files but it gives me error that i have to convert colorspace to YUY12
If i dont use any filter then MEGUI convert colorspace to YUY12 itself but it distort the video

2- There are many .avs scripts as well how do i use them

NOTE: These are FRAPS recorded videos in raw form of avi and colorspace is rgb

Some avisynth scripts only work with certain colorpsaces. See http://avisynth.org/oldwiki/index.php?page=Section+3%3A+Filters%2C+plugins+and+colorspaces

Hi

Megui just auto updated some of its files including mkvnerge to version 4.9.1.

Since updating it appears that mkvmerge is recompressing / altering the audio track during an audio/video multiplex using tools/muxer/mkv muxer.

This never happened with the previous version.

Is there anyway to rolback to the previous working version? or workaround for this issue?

Help apreciated

Thanks

Heres a log of the last multiplex. Video + Audio should be 1.80 GB but is coming out at 1.58GB.

mkv don't support a track TrueHD / Core (TrueHD + AC3), if you want both you must extract first the TrueHd and the AC3 audio and mux like 2 independent tracks.

Hello everyone :) . A while ago, I had asked about quality settings for H.264 encoding. And thank you to the person who suggested the CRF mode, I love it.

But unfortunately, the Xvid encoding doesn't have a CRF mode, only CQ :( . So I need to know, what is a good CQ range for encoding to Xvid 640x480?

I'm trying with virtualdubmod and I can perfectly open the .avs without any problems, and I have tried to open with avidemux (avsproxy (wine) and avidemux(linux)) and it opened without any problems.

¿How I can resolve this problem?¿Can you help me? Thanks :D

[Sharktooth]

What preset you used? Please load the default settings and try again. It seems you have messed up the key-frame interval value.

[Jisana]

Thanks for reply. ^^

I used the "x264: Unrestricted 2pass Anime_Toons HQ" preset.

program --level 4.2 --tune animation --pass 2 --bitrate 1168 --stats ".stats" --qpmin 10 --qpmax 51 --vbv-bufsize 31250 --vbv-maxrate 31250 --me umh --direct auto --subme 6 --partitions p8x8,b8x8,i4x4,p4x4 --no-8x8dct --trellis 2 --output "output" "input"

I'm using now "Simple X264 Launcher" with this parameters and I don't have any problems, it's only when I use MeGui and I don't known why.

---
I have put the defaults settings and it says the same XD

[Zathor]

Add Info() to the end of your AVS script, open it with e.g. virtualdub and post the output. I am especially interested in the line frames per second.

My problem is when I try to open a video in 16:9 (1.7777777), megui CRASH.


I can open any resolution except 16:9 like 1280x720. If I put in my avs "final = final.lanczos4resize(1260,720)" (1260:720 = 1.75) . Megui runs OK. But If i try to open a video in 1280x720 megui crash.
The framespeed is OK
The megui preset is Ok
Avisynth is ok
Virtualdubmod Ok
Simple x264 launcher OK
Megui (loading video which not is in 16:9) OK
Megui (loading video in 16:9) no ok XDDD
Why i don't know but this is a mistery XD

[hello_hello]

Hello everyone :) . A while ago, I had asked about quality settings for H.264 encoding. And thank you to the person who suggested the CRF mode, I love it.

But unfortunately, the Xvid encoding doesn't have a CRF mode, only CQ :( . So I need to know, what is a good CQ range for encoding to Xvid 640x480?

A quantizer of 2 is as good as it gets with Xvid. The higher the quantizer, the lower the quality. I probably wouldn't go any higher than a target quantizer of 3.

A quantizer of 2 is as good as it gets with Xvid. The higher the quantizer, the lower the quality. I probably wouldn't go any higher than a target quantizer of 3.

Thanks! I look forward to experimenting :) !

[LigH]

The MPEG4-ASP quantization steps are quite coarse, using the defaults (H.263 parametric quantization, or MPEG matrix quantization with the standard matrix); using a different matrix for the MPEG quantization may be the only way for Xvid to achieve finer steps and better control, but may have side effects...

[hello_hello]

I still use AutoGK for Xvid encoding because it tells you what quality to expect when running 2 pass encodes, although that's probably a discussion for a different thread.
AutoGK uses a quality setting of 75% for single pass encoding by default. Depending on who you ask, 70% to 75% is supposed to be the optimum quality, file size ratio for Xvid. Looking at the way AutoGK configures the Xvid encoder, a 70% quality single pass encode equates to a quantizer of 2.86, while a 75% quality single pass encode equates to a quantizer of 2.67
If you're only going to be running single pass encoding (I run 2 pass encoding only to maintain 100% standalone player compatibility... although again that's a different discussion) and if file size isn't really an issue for you, I'd just use a quantizer of 2 and be done with it.

Personally I prefer the default H.263 quantization.... as long as you use a low enough quantizer anyway. No doubt custom matrices can achieve similar results with higher quantizers or lower bitrates etc, but I've not experimented with them all that much.

[LigH]

Do not confuse "higher" and "lower" regarding quantization.

To achieve similar bitrates, the product of matrix coefficients and overall quantization factor (or quotient) shall be about equal. If you use a matrix with smaller coefficients than the default, the overall quantization will have a bigger average value for the same target size.

Hi,

I kindly ask you for two short questions, thanks in advance!

My clip sources are .MOV clips of photo cameras, at 33 Mbps.

A) I found comparable media info output between a single pass with CRF 21, and a 2 pass insane with bitrate selected to 11 Mbps (one third of the original bitrate). Should I prefer the 2 pass?

B) Do I loose something decreasing to 11 Mbps? My 1080p TV sees both (original and encoded) files and I cannot distinguish any difference.

Note that I used for both the same preset, the veryslow

Here the relevant media info:

x264.exe --preset veryslow --pass 2 --bitrate 11000 --stats "file.stats" --deblock -1:-1 --qpmin 10 --qpmax 51 --no-dct-decimate --sar 1:1 --output "file.264" "file.avi.avs"

[LigH]

A) The more important it is for you to reach a certain file size (e.g. get media filled to the brim), the more probably you will decide to use 2-pass instead of 1-pass CRF.

B) Using lossy technologies, you always lose quality (objective loss = any measurable difference). That doesn't mean that you can spot the difference at all, or would rate it annoying (subjective quality loss).

The slowest presets are already "pacebo" if you have a convenient bitrate (hard to rate certainly, but a pixel bitrate around 0.2 bppf is already quite convenient for x264). They may only give an edge for really tight cases.

The 1-pass constant bitrate mode is the one with the least certain quality, only useful for transmissions with tight bitrate specifications. For storage and playback from fast media, you should always prefer either 1-pass constant quality (CRF) if you have no important filesize constraints, or 2-pass mode if a filesize limit is more important than a quality level.

Note: CRF mode encodes to a fixed grade of objective quality loss. If the source is easily compressable (e.g. little details, little motion), the result may become smaller but will still look good compared to the original. If the source is hard to compress (a lot of details, noise, motion, etc.), it will use more bitrate to ensure that the copy will look good compared to the original. The smaller the CRF factor, the smaller the objective loss accepted by the encoder, the higher the possible bitrates. Average viewers may find a CRF around 21 acceptable; cineasts may agree that a CRF around 18 almost guarantees a "transparent result" (hardly noticable differences to the original).

Vielen dank LigH

I have learned something new about the pixel rate. You meant that 0.2 bpf would be good for x264. I re-encoded my sample with CRF 18 and with the 2 pass of bitrate 18 Mbps. Please have a look on the table below:

https://docs.google.com/leaf?id=0BxK6VmqKqXslZmExYjkwZmEtMzFhOC00MDAyLThjZGMtNDNmYjU4YWY2MTE4&hl=en_GB

I see that the pixel increased from 0.2 to 0.36, which must be good (I hope :-)

Could anyone tell why Canon/Nikkon, etc., prefer shooting with the avc1 codec on the original .MOV file? Do I really make the good thing to convert with x264?

I know that x264 is a multiple award winning sw, and is the best we have in compression by now, probably the preference for avc1 is given by the limitations of the CPU times of the photo cameras.

It was impossible to load an image, the link to an URL did not show-up, columns are not aligned. Sorry. I hope you understand my ideea, having the original and the two encodings side by side.

Of course - a camera needs to encode the video in realtime. Therefore it has to use a less complex encoder setup, creating only the Baseline profile and a lower number of reference frames (but your 16 for x264 are exaggerated, ~5 are usually efficient enough but a lot faster).

Therefore, because the hardware encoder creates AVC video with limited complexity and limited encoding efficiency, it prefers to put more bitrate in it to ensure a good quality even in complicated scenes.

x264 instead has all the time you allow it to take via your speed preset choice. It can (hopefully) use a powerful CPU with several cores for code parallelization and efficient Streaming SIMD Extension instructions for further data manipulation parallelization, along with (up to) Gigabytes of RAM to store frames to compare and search for redundancies (similar areas which can be used to spare bitrate by storing only smaller differences instead of plain values).

So there is no surprise that x264 is able to preserve a similar amount of video quality already with a smaller file, and, divided by the pixels per frame and the frames per second, a smaller "pixel bitrate". Its unit is bppf = "bits per pixel and frame"; think about this meaning.

The encoding shown above used the preset slow reducing thus the ReFrames from 16 to 5. The encoding time decreased from around 70 to less than 20 minutes!

The 16 Mbps correspond to a CRF 19 and to a decrease of the size of the file from 300 to 130 MB, quite impressive.

It is even possible to go on youtube, etc., if not by 2011, but surely in a closer future.

To summarize then, x264 options used for the current run:

program --preset slow --pass 2 --bitrate 16000 --stats ".stats" --deblock -1:-1 --qpmin 10 --qpmax 51 --no-dct-decimate --output "output" "input"

[LigH]

Now you just have to understand:

For one movie, 16 Mbps may be a waste.
For another movie, 16 Mbps may be tight.

Find the CRF which creates a copy good enough for you not to spot annoying quality loss for several different movies. This will be your "threshold of transparency". From then on, always use this CRF value in 1-pass encodings, spare a 2nd pass you don't need, as well as bitrate calculations -- if you don't need to fill a disc to the edge.

[vale25]

Understood your point!

Then I would start with a CRF 19 with preset slow. For general purpose home made videos (with my 2 years old daughter) it is probably more than enough.

If I get lots of movement in the scenes (water in the pool, speedy movements) I should try first to decrease the preset to slower (keeping the same CRF 19). If still has defects I go to CRF 18 (enlarging the file).

What about night scenes, are they "more difficult" than by daylight? Could you generally recommend something for them?

I need to shoot more scenes to prove that this strategy is the "perfect" way. However, your support was essential, danke again (I come from the photographic world and learning about movies is not so easy, at least for those who establish for themselves higher quality standards :-)

[LigH]

Night scenes are more difficult, because a smaller dynamic range is usually interpreted as less important by a video encoder. But x264 has already quite good psychovisual features. Try to find more facts about the "Variance AQ" (adaptive quantization) modes and their relation to tunings (--aq-mode / --aq-strength).

I never see this error with NeroAacEnc but you can try some test to evaluate the problem.

1) Try with bigger bitrate, maybe -br 64000, and see if work now.

2) Extract the DTS with Tools -> HD Streams Extractor and use NicAudio decoder instead DirectShow
