    x264 --bitrate 25000 --preset veryslow --tune film --bluray-compat --fps 24000/1001 --force-cfr --bframes 3 --ref 4 --no-weightb --weightp 0 --b-pyramid none --vbv-maxrate 30000 --vbv-bufsize 30000 --level 4.1 --keyint 24 --min-keyint 1 --open-gop --slices 4 --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --sar 1:1 -o out.264 input.file

     

    Can you encode a 1920x1080p23.976 with the settings above and try it in encore. If this doesn't work then try by replacing --bluray-compat with --aud and --nal-hrd vbr.

    The minimum requirement is shown here

     

    http://www.x264bluray.com/home/1080i

     

    I have just built a 18gB blu-ray ok. I found that encore was very slugish with a .264 file. I multiplexed with tsmuxer to a m2ts file and it was alot better and did not transcode.

     

    By the way I assume we are all talking about CS6.

    Try this, use the settings that worked and add --muxer raw.

    Ah!! 10 bit. X264 does support high10 so try adding --profile high. You could try --level 4.1 aswell. Does the mac x264 support mov files then.

    Encore and blu-ray only support 8bit.

    I agree with tjh65 that using 10 bit can be the reason why it's not working. The highest profile and level that can be used on blu-ray is high and level 4.1, blu-ray also only uses 8 bit and 4:2:0. I don't know if you are also using 4:2:2, so try with a source file that is 8 bit and 4:2:0.

    x264 should convert 4.2.2 to 4.2.0. Well it does on windows. You should be able to see the conversion mentioned in the x264 log. There are couple of options you could try --output-csp i420 --input-csp i422 if these are right for your system. I use avisynth to do the conversion 4.2.2 -> 4.2.0 but I don't think you can do that with mac.

    I wonder if it would work if we used another codec when exporting to quicktime. There is a codec called DNxHD that can be downloaded from here: http://avid.force.com/pkb/articles/en_US/Download/en423319?retURL=%2Fa rticles%2Fen_US%2FDownload%2Fen423319&popup=true

    This codec is also available for windows, so this codec can be usefull when working with both MAC and PC. This codec is only available when exporting to quicktime, but I don't think that this is something to complain about when using a coded that is freeware.

    This problem needs to be fixed. EIther you need to convert your file to 4:2:0 or swscale needs to be compiled into x264. I do not use a MAC so I realy cannot help any further. If you can get an ffmeg with swscale it will convert your file 4:2:0. I did find some info when I googled the error message.

    Hi Eric,

     

    Mpeg2 support's both 8 bit and 4:2:0, so try with a mpeg2.

    my source file is 4:2:2. Do you have any idea how to change that to 4:2:0 on a mac?

     

    Premiere Pro can export to mpeg2 and mpeg2 uses 8 bit and 4:2:0, so Premiere Pro must convert 4:2:2 to 4:2:0 if you import a 4:2:2 source and then export it to mpeg2.

     

    Mpeg2 can also use 4:2:2, but not all mpeg encoder's allow's you to use 4:2:2 I don't know if you can use 4:2:2 when exporting to mpeg2 in newer version's of Premiere Pro, but if you can then use 4:2:0.

     

    We are now also going to use mpeg2 instead of uncompressed 10 bit 4:2:2 when encoding with x264, so we need to use the highest possible bitrate when exporting to mpeg2.

     

    The maximum bitrate that can be used depends on what profile and level we are using, but Premiere Pro should allow us to use at least 80 Mbit when using profile: High and level: High

    I can understand if a program has problems using a 10 bit and 4:2:2 source, but I can't understand how the same program can have the same problem when using a mpeg2 8 bit and 4:2:0 source.

     

    Can you upload the mpeg2 that was exported from Premiere Pro and also the H.264 that was encoded with x264. I need to analyze both files to se if I can get any clue on what's going on.

     

    I have also another sample x264.264 that you can download and try in encore. The sample can be downloaded from here: http://hem.bredband.net/b131706/

     

    This sample is encoded with x264 with the same setting's that I have posted in this thread, but this sample has been encoded with the window's version of x264.

    The mpeg2 from Premiere Pro is OK, but the H.264 from x264 is NOT OK. The video properties of the H.264 is Ok, but the video data in the H.264 has been corrupted.

     

    I'm using Windows, but x264 probably relies on that the MAC OS is capable of decoding mpeg2. The MAC OS is also probably using Quicktime for decoding mpeg2, so is the mpeg2 from Premiere Pro playable in the Quicktime Player.

     

    My guess is that both the mpeg2 from Premiere Pro and my H.264 play's perfectly in the Quicktime Player.

     

     

     

    Sorry for the late reply, but don't worry, I haven't given up yet.

    The mpeg2 from Premiere Pro AND your .264 file are NOT playable in Quicktime Player (I have two versions and it's the same). It says "this is not a movie file". In fact, the .264 files are only playable in Encore (even VLC does not seem to be able to play them).

     

     

    This confirmes that the problem we are having is codec related. The question now is if x264 is using Quicktime. Quicktime should support mpeg1, so try encoding a mpeg1 to H:264 with x264 and then try this H.264 in Encore.

     

    Please note that Mpeg1 is not allowed on blu-ray and that mpeg1 also doesn't support's interlaced, but this is only to se if we are still getting the "green picture with vertical lines* in the preview window.

     

    Some software player's, like VLC, doesn't like playing raw H.264 video streams. The workaround is to mux the raw H.264 video stream into a mpeg2 transport stream.

    On another note, I have tried this tutorial and I got something that almost looked like video. They suggest to transcode in various formats (most notably, AVI) with ffmpeg before sending to x264. But the transcoding somehow affected the gamma and placed weird subtle patterns over the video... The AVI also does not open in Quicktime. But it's the closest I got to a real image in Encore by my own means.

     

     

    AVI is not the best format to use on a MAC because AVI is mainly used by Windows, and I don't think that Apple is that eager to support it. We need to find a format and a codec that work's in Quicktime, so try to se if you can find a combination that work's without using AVI.

     

    Eric_Daoust wrote:

     

    You think it might have something to do with Quicktime codecs?

    Yes it can if the AVI that you exported from ffmpeg is decoded by Quicktime.

    Stan,

     

    Thank's for posting that information.

     

     

    Eric,

     

    Here is a mpeg and quicktime sample that you can download and try in both Encore and the Quicktime Player.

     

    Both sample's play's perfectly in the Quicktime Player for Windows. The samples can be downloaded from here: http://hem.bredband.net/b131706/

    I am having the same problem it appears.

     

    I have tried creating a standard DVD in encore - bringing in numerous files made of Standard Definition originals - converted to H.264  and/or .avi  (large, small, high quality exports, Youtube exports, numerous versions.... all exported converted with either Premiere Pro, or Matrox) The exports look fine (generally).

     

    All of these files play back and look (generally) fine in Quicktime or Windows Media player.

     

    Once I bring them into Encore they come up UNTRANSCODED and they look like crap, low quality. I am trying different project settings - DVD / BluRay / both different frame rates.... the video clips look like crap. I have'nt even bothered to try to create a DVD.

     

    This is a major flaw I believe. I paid a solid amount of money, and have software that does not work it appears. I will keep watching, reading, listening, and definately keep the best attitude I can. I have had Adobe  Encore for years, and PPro. Now I have CS6. I need a DVD authoring program that does not degrade my video this horribly.

    They both play perfectly in Quicktime for me too.

     

    This mean's that Quicktime is correctly decoding both Mpeg1 and  Quciktime Prores files, so the problem is either with x264 or something else.

     

    Can you upload or post the link to the exact same x264 version that your using. I have asked a friend of mine that also uses a Mac to try this on his Mac to se if he also get's the same "buggy output*.

    Hello. I'm trying to encode with X264 and MeGui and using in Encore CS6. I'm unable to do it. I'm using DNXHD sequence exported from premiere in MAC. Then in Windows compressed. But when returned to Encore in MAC again it says untranscoded. x264 is ok because i can see the video in Encore but always says untranscoded.

     

    1080 25p

    @PMK3: I also have access to an old "almost dead" 2004-2005 Windows XP Home Edition PC... I could try that if everything else doesn't work.

     

     

    I found a file with the exact name as you posted, but it was only the source code and my friend wasn't interested in trying to compile it on the MAC.

     

    What  codec's did you use when you tried the AVI format. AVI isn't the best format to use on a MAC, but uncompressed AVI doesn't use any codec's. If you are also getting the same "buggy output" with uncompressed AVI , then perhap's the easiest solution is to use a PC.

    Any good step-by-step tutorial to install x264 on a PC?

    x264 on a PC doesn't need to be installed, just download the x264.exe file and run it in a DOS-promt. Codec problem's are also easy to fix in Windows, just download and install the codec that you need.

    I'm not using MeGui, so I don't know if you can encode a Blu-Ray compliant file when using MeGui.The best way to encode a Blu-Ray compliant file with x264 is to use it without any GUI.

     

    1080 25p is not allowed by the Blu-Ray spec, so either encode it to 25i or slowdown the framerate to 23.976p or 24p.

    Yes i know that you are using only x264 without gui.  Please post your final settings to get a good video in Encore. I know that i can't do 25p but if give me a valid frame rate to get PAL BluRAY with 25p or 50i with 25p sequence. I don't want to transcode to 24p because in Spain is 25p.

     

    I want to transcode Avid DNxHD to x264 and bring back to Encore

    ThankYou
