Fields = frames for the camera when it's interlaced. But it keeps one line on two.
59.94 fields = 59.94 different frames wich can be reconstructed with a good de-interlacer to get 59.94p on a recent screen.
When your interlaced file contains actually 29.97 different frames, you don't have to keep it interlaced, it's not useful and you loose bitrate for nothing.

Sorry, but not true. A video source (camera, computer generated, etc) that is putting out interlaced video still has frames that are 1/2 the field rate. You can never, and I repeat never, have a field rate = to a frame rate. It is technically not possible. It always takes two fields to make a complete frame. Always has, always will.

BTW, did you know that with PAL analog video, it actually takes four fields to comprise a color frame? The color phasing for PAL is spread over four fields.

blend = join when the source is progressive, it's a simple 2:2 pulldown.

But, you must know if the source is one or the other, in order to set up the correct encoding.

Anyway, like I said, unless absolutely necessary, I do not screw with interlaced video unless I IVTC the video into 23.976 frames/sec. Everything else I do not touch.

And it's an error, because 23.976 is one between three cases (on dvd) where you can find really progressive sources (with 25p and 29.97p, encoded in 50i and 59.94i).
I don't understand why you absolutely need to believe that interlaced encoding equals interlaced content.
I believe we can stop this discussion here, people have enough elements to understand what we mean and make their own opinion.

I just listed 23.976 as it is pure progressive video on a DVD, where the DVD player does the 2:3 pulldown. That's all.

I don't understand why you absolutely need to believe that interlaced encoding equals interlaced content.

Even if the video source is from 29.97 frame/sec progressive video and converted to interlace for DVD/NTSC analog output, the content on the DVD is still interlaced, no matter the source. So what if the video you look at appears to be progressive, the video content is still interlaced as it contains two separate video fields, which will be different.

How can I download the newest x264 presets?

- Build 2028 doesn't have them included
- Update does it want to download them
- Stable server doesn't have any

Why are x264 profiles missing, for me this was pretty much the only reason why I used MeGUI, because it had the best x264 profiles!

Trying to send a downscaled, compressed screener/sample video to people in Apple-land.

I rendered a 1280x720 H.264/.mp4 file with x264 in MeGUI with default settings and crf21 (i.e. not deliberately dumbed down for Quicktime). I told them to rename it to .mov if they had trouble and they've said: "While changing the extension to .mov may assist in viewing, we need to convert the files to a quicktime format for delivery to the client". The can't do that on their Macs.

I opened the file in Quicktime Pro and rendered to H.264 .mov. It took about 20 seconds to render a solid green file.

Has anyone found a way to smart-render or remux MeGUI/x264 output to .mov, and did the file play OK on the recipient's Apple computer?

If it is possible, should I be choosing a dumbed-down preset rather than defaults?

Or am I basically stuck with exporting an uncompressed or lossless intermediate and using Quicktime Pro's H.264 encoder?

It could be a simple filter problem in your player, but this mov file is maybe good.
Is it recognized as a Quicktime container in MediaInfo ?
Does MediaInfo show the same characteristics than your mp4 file ?

MediaInfo recognizes it as a Quicktime container but the framerate and bitrate and filesize are all tiny. Looks like Quicktime Pro won't smart render, so if I'm going to use that then I may as well output a lossless intermediate for it from my NLE, rather than feed it a MeGUI x264 file.

I tried a render with Xvid4PSP 6.0 beta 3, which I heard might do it. Much better but took too long to be doing a simple smart render/remux. Also it seems to have included the dreaded Quicktime gamma but, so the video is now too bright, with blown out highlights.

Any other suggestions?

Having some trouble with the avisynth creator. Keeps saying I may not have a yv12 decoder installed. Only recently has this been saying this. Can't open scripts in vdub either. Maybe something related to one of ati's driver update packages (it includes a decoder of some kind)?

Tried correcting it with the win7dsfitler but that doesn't seem to be able to access a decoder for yv12. Also tried using ffdshow to set it to decode yv12 but couldn't find that format in the ffdshow decoder window.

In ffdshow VFW, in the codecs list, go on the last line (uncompressed video) and choose YV12.

You may also need to add this line in your script ;

Thank you sir. That's helped tremendously since it has fixed that problem.

Does anyone know about the explorer hang when using megui to open explorer (like opening a window to locate a d2v file or opening a window to find audio for the bit rate calculator)? That would help too seeing as megui hangs after about every third or fourth time I use it to access/open explorer. Like right now I can't use the bit rate calculator because it freezes on me. Win7 will just as if I just want to close it or I'll have to delete the process. Any help there would be appreciated as well.

@ nhope : VLC can also mux into quicktime container without re-encoding, but it didn't work well with my version (0.9.2, yeah, it's old). I tried it with 2 mp4 files, same result in both cases ; the resolution, framerate and duration are wrong but the size of the file is good.
It could maybe work better with a newer version.

Thanks for your help. I decided to use Quicktime Pro in the end. I worked out that "Export" always recompresses (and looks horrible), but "Save As" will remux, as long as the streams are acceptable. If it won't remux it says it is going to save a really tiny file, like 10kb, and then it just doesn't do it. The closest to x264 defaults I could get it to remux was as follows. No B frames and no Weighted P frames, and I8x8 turned off by selecting the main profile:

program --profile main --crf 21.0 --bframes 0 --weightp 0 --output "output" "input"

I used Nero AAC-LC cbr 128k for the audio.

I never used avisynth creator, but to open d2v files with avisynth, one needs DGIndex and the "DGDecode.dll" file in the plugins directory of avisynth.

4th July 2011, 11:47

Never had to manually place it in there before... Even if I did put it in there why would I be able to open d2v files with the avisynth creator when I've been able to already? It seems odd that I can't open certain ones when they are very similar dvd's (sesame street). I've attached a picture of the error. Maybe it'll help.

edit: and just to let you know, I did put it in the folder just to give it a shot. It still didn't work.

LigH

4th July 2011, 13:42

The d2v project files must be generated by the DGIndex.exe of the same version (or "generation") as the DGDecode.dll the script uses for MPEG2Source.

Do you possibly have several different DGMPGDec packages on your PC (including the one in megui\tools)?

Furthermore, the indexed media files must not be moved after creating the project file, as it contains the full path from the drive letter.

rtjnyoface

4th July 2011, 19:36

Megui used whatever the latest updated versions there are (which is 1.58b). I do have different versions but the only other one was unzipped onto the desktop. I don't see how that could be an issue.

I know it shouldn't be moved. When I did move them I made sure to change the paths. Either way, I just went back and redid everything according to the way you had indicated. Used megui to create the indexed file (to make sure the same versions were used) and I didn't change the file location. Still the same error.

FFmpegSource is not always preferable for AVIs. Sometimes only AviSource works reliably. Probably related to the demultiplexer used by FFmpegSource.

If there is no better way provided by the GUI ... then by loading a manually edited AviSynth script.

Ok, thanks. So far the best way for me is to avoid indexing AVIs. Using just DSSource for creating AviSynth script works just fine. If there's no corrupted ffindex files nearby in working directory from previous unsuccessful tries, which MeGUI tends to load automatically.

8th July 2011, 10:35

Using DirectShowSource always has a risk of unexpectedly filtered video or not frame-exact decoding (1st pass differing from 2nd). That's quite a "desperate last chance" technology, if all native AviSynth sources did not work.

How do I use AviSource with MeGUI then?

Try creating a simple AVISynth script manually. Something like:

AVISource("D:\video.avi")

Then open MeGUI's AVS Script creator and use your manually created script as the source video.

Mind you I've encoded hundreds of videos using DirectShowSource (different GUI, different reasons) without any problem.

Hello,
I noticed some strange behaviour of MeGUI. Not until recently, opening a MKV inside the AviSynth Script Creator results in popping up this question: "please choose your prefered way to open this file". Screenshot:

http://img594.imageshack.us/img594/3774/screen0008.png

What is this?
I don't want to use the One-click encoder. Running FileIndexer fails, because there is "nothing to do" - according to log.
So I click DirectShowSource, because I always use DSS with MKV. Script creation works as usual. But the encoding of the video does not. Either x264 or vfw4x264.exe always crash a few minutes after the encoding process started.

What's going on? I use MeGUI 2028 (svn). Am I doing something wrong? My MKV contains a single stream, which is either h264/AVC or VC-1 - always was.

Advice will be highly appreciated.

Me again. :)

I did some testing and without any specific reason I considered the source material (MKV with AVC stream; source is Blu ray "Avatar") as corrupted. Somehow. I re-ripped all the stuff, which took only half the time. Could be a coincidence.

Now, running the FileIndexer (with FFMSIndex as the only available option) works and took around 5 minutes. It produced a file namend avatar.mkv.ffindex. Loading this file into AviSynth Script Creator creates an AVS script, which uses the FFVideoSource plugin. Encoding seems to be working now. This conclusion is based on 15 minute encoding, because my reported crashs of x264 happened within 5 minutes. And it even seems to be working without a crash with the DirectShowSource plugin, I've been using so far. Maybe it was a bad rip, actually.

Anyway, can someone explain me the difference between FFVideoSource and DirectShowSource.
Is there any reason, why I should start indexing MKV files? I read some stuff here and there, but I didn't really get what's this all about.

Thanks,

My understanding of it is FFVideoSource should be frame accurate, whereas DirectShowSource... not so much.
Having said that, I've encoded around a billion AVIs using DirectShowSource with no problems at all (well at least not DirectShowSource related ones).

3rd August 2011, 09:35

If you're just converting a video, DirectShowSource should be okay. If you need to make cuts you are safer off with FFVideoSource or some other equivalent frame accurate reader.

So I'm trying to do the audio portion and I choose 'Create AVS Script Creator' and then I choose my .m2ts file and I get the option to use DirectShow, 1click, or File Indexer. I choose 'File indexer' but instead of it allowing me to create a d2v file or anything, I can only use the FFMSIdex option so I don't have a clue on how to do the editing or anything as when I try to load it, I don't see any video preview. How can I correct this?

I don't think you can open ffmsindex files directly, but after it's created the preview window should open normally. Maybe it's an m2ts problem as I don't think you should work with m2ts files directly. It's better to extract the video to an MKV file and the audio separately using MeGUI's HD Streams extractor.
I generally use it to extract the contents of the m2ts files directly from the disc. There doesn't seem much point to ripping the m2ts files to your PC and then having to extract the video/audio streams anyway.

Hello everyone :)
My English is not good so I hope you don't smile when I make some grammar mistakes :D
I have a question about mode Constant Quality of Megui. There's a parameter called 'CRF' which makes me confusing.
Can you explain it for me?
And how can I set the value of CRF to encode a video with these resolutions : 480p, 720p and 1080p to achieve excellent quality ?
because I see the recommended value is 23 and I wonder that's the optimal choice and for every resolutions or for only the specified resolution
Thank you very much :thanks:

hello_hello

9th August 2011, 23:09

The CRF value you'd use depends on the quality/file size ratio you're happy with. The lower the value, the better the quality and the greater the file size.

Personally, I use CRF19 for all 480p encodes and CRF20 for all 720p encodes because that gives me a quality and file size I'm happy with.
I don't generally encode at 1080p because to keep the file size down I'd end up using a CRF of 22 or 23 and I think a 720p CRF20 encode looks better.
It's all personal preference.

My 4Gb's of ram is fine, I've checked multiple times. I've never had this error before on dvd's ever, only with this file. I've even analysed 1080p avc's with hardcoded interlacing fine before. I suspect it might have something to do with the filesize, or maybe even the file itself.
Here is a mediainfo readout on the files stats if that is necessary.
http://i.imgur.com/PazN2.jpg (http://imgur.com/PazN2)

I can't figure it out, it happens every time after 5 or so seconds.
Should I post a segment for someone else to check out? What's the proper length someone would need for an interlaced file?
This problem occurs on both the latest stable release of MeGUI and the latest dev build, and I'm running the latest Shark007 x86 codecs on Win7.
Cheers.

Edit:
Here is a 70mb piece of the avc file in question. I'm not sure I split it properly, but could someone try this out on their PC to see if it works?

So I have a small question
When I rip my video in CQ mode, I often realize that its bitrate decreases so the capacity of video also dereases too.
But with some MPEG-2 video, especially type 1080i => its bitrate increases :eek: and so that the capacity of them rises :eek: (I often choose value 18 of CRF to rip 1080i video)
Why is it???
And so with these types of video, how I should do to rip them?
Because my hard disk capacity is becoming low :rolleyes:
