    You can use any encoder (although the GPU based encoders produce a relatively worse image quality and the gain in speed is minimal). Just select Settings - AVC/HEVC Encoder - Use your own custom command for encoding. Then, in the last tab, type the command line you need to use your encoder.

    For example, for nvenc, you can use something like this:

    "path\\to\\nvencc64.exe" --codec avc --cqp 26 --profile high --level 4.1 --preset quality --sar ${sar} --chapter chapters_3D_delay.ogm.txt --key-on-chapter --input "__ENCODE_3D_MOVIE.avs" --output "video3D_nvenc.avc"

    Of course, this is only an exemple. The exact parameters are up to you.

    Note that ${sar} is a variable that will be replaced by the correct SAR value by BD3D2MK3D. Note also that the output file name must be copied (without the quotes) in the Filename field. And take care: the / must be replaced with \\ in the path names. See the help for more info.

  2. Thanks. Yes it's about 1.64 times faster, but the output is bigger. Maybe we can adjust some params.

  3. A higher cqp value will give a smaller file, but a less good quality.

    All parameters are here, but it is not easy to understand their exact usage. There are also many sites explaining the "best options" to use, but take care. Many sites are totally wrong. For example, the suggestion to use --cbr instead of --cqp is crazy, as CBR (for Constant Bit Rate) is certainly the worst mode. It creates a big file for a very bad quality. It should be used only in very specific cases, such as encoding for some VR lenses. In the other hand, --vbr (for Variable Bit Rate) is better, but to obtain a really good quality through the whole movie, it is necessary to use the 2-pass mode, and that require to encode the same file two times. In that case, x264 (CPU based) in one pass CRF is faster ! IMO, cqp is the best mode. It is equivalent to the CRF mode of x264 or x265, the default in BD3D2MK3D.

    You can also encode in HEVC (h265) format. The quality is better than with AVC (h264), and the file size smaller, but the encoding time is much longer, and many hardware players do not support the HEVC format yet (or not correctly). The HEVC parameters are also more difficult to master.

  4. Thanks! Makes sense. My initial reason to convert was because I couldn't figure out how to play bd3d files on my 3d tv. Apparently the Stereoscopic player can convert on the fly. It's a good alternative for this use-case.

    I used to use nvenc then I started using x265, but now I stick with x264. On a decent machine, x264 is almost as fast as nvenc but with reliable quality. x265 takes around twice as long and has issues with low light and low bitrate scenes.

    Try mpc-be which is also able to convert on the fly. I remember helping the devs find a bug caused by a regression in the 3D rendering code. The only reason I no longer use it is because I can get almost identical picture quality for around half the file size or even less. But it's probably the best free 3D player.

    Hi r0lZ,

    As you know I often make use of your subtitling positions cloning tool. I wonder if you see a possibility to implement altering timecodes. I'm doing a lot of image-based positioning editing in Subtitle Edit's SUP editor (not to mistake for the standard text GUI). This tool offers to import video where image-based subtitles are displayed at the correct, authored positions. Often I find that adjusting timestamps is necessary, which I then do in this tool. I can export the result to both SUP and XML/PNG.
    Here's the thing. I'd like to see this result as my own "guidefile" (with the corrected timestamps and positions) and import it in your tool. Already possible of course, but I'd love to be able to replace the timestamps of the "Input subtitle stream (XML/PNG)" with those in "my guidefile (also XML/PNG)".

    Any chance?

  7. Hi Ennio.
    I'm not sure I understand the interest. If you have an XML/PNG stream with the correct time codes, why do you need to use the original stream? You can easily apply the depth values of the original OFS file to the new subtitle stream.

    The only problem you may encounter if you have changed some timestamps dramatically is that there will be no depth values corresponding to somewhat large regions of some subtitles. But you know already that, and I suppose that your timestamps edits are not so radical.

    Damn, I realise I'm going in a circle here. I was looking for a way to correct timecodes of a source-text, by replacing them with those in corrected imaged-based. But I totally overlooked that SE's "Import timecodes"-feature also accepts XML. I can already directly point to my edit. Doh...
    Please forgive the (hopefully temporary) malfunction of my brain, launching me into chasing my own tail once again.

    Here it concerned non-3D material. And indeed, the timing differences aren't that big generally, but a few times a couple of seconds had to be done. Both in start- and end times.

    Anyways, back on track again

    Hi all, I converted a disc yesterday (Ghostbusters 2016) and got some really bad blocky artifacts during certain parts (see images/video).

    Image
    [Attachment 77954 - Click to enlarge]
    Image
    [Attachment 77955 - Click to enlarge]

    https://www.youtube.com/watch?v=5_4m6uQVNqE

    Full SBS, CRF 10, Preset placebo, Tune none, Level do not force, 8-bit color. No extra command line options used.

    The image looks fantastic aside from this blocking; no color banding and everything looks crisp. The blocking is only noticeable some of the time, but when it is, it's really distracting. Any tips to remedy this?

  10. In the settings, try to disable the hardware acceleration of the MVC decoder. And, if you have an Intel CPU, try to update the Intel drivers.

    Thanks for the reply. I turned off hardware acceleration, although I didn't update any drivers because I couldn't figure out which ones you meant exactly. Did you mean my CPU's integrated graphics driver? If so, I have an RTX 4090 GPU, is there any way to make sure that is being used rather than my CPU?

    Running it again with hardware acceleration off, the process stalled out around 19%. When I played back the partial file, the artifacts were still there, actually slightly worse this time. I also changed the aspect ratio from 16:9 to 32:9 (I meant to do that last time but forgot), so that may have affected things.

  12. No, the MVC decoder's hardware acceleration uses the Intel CPU, not the GPU. The drivers are the Intel drivers for your CPU. But I suppose that the problem is not due to the MVC decoder, since if you have disabled the acceleration, the MVC decoder provided with BD3D2MK3D is used and the Intel drivers are not needed.

    similar problem has already been discovered in the past, and it was due to a bug in the Intel MVC decoder, happening only with some specific BD3Ds. Since the bug is fixed now, I can only suspect a bad BD rip. Can you retry with another ISO or source MKV? Sorry, I can't help much more.

    I tried it with two other ISOs and they seem to be perfect, so yeah it seems to have just been a problem with my Ghostbusters ISO. Sorry about that, but you don't need to apologize at all, you were very helpful! Thanks again!

  14. Hi , I'm using BD3D2MK3D V1.33 to batch encode 4 BD3D RIPS I made.

    1. After finishing the encode and not completing the MUX to MKV file (so I can batch encode later).
    2. I enter the FILE > Batch Encode section and open each of the __ENCODE_3D.cmd files from four separate folders and then hit cancel -so it can modify the command batch files to run one after the other.
    3. I then run the first __ENCODE3D.cmd command file and on completing several of the x264 command scripts, I can not find the movies once completed.

    When completing the videos individually, they would end up in the folder that I stated in BD3D2MK3D (the original documents folder) - however I cant find them. Even with Windows Search.

    Any advice what's going on? Thank you so much in advanced.

    I've copied the batch text document to see if it helps with locating the final MKV files. thanks!

  16. The mkvmerge command is commented out :
    Code:
    C:\Users\Seb\Documents\The Hobbit- An Unexpected Journey Disc 1\MKV3D>REM "C:\Users\Seb\Desktop\3D Bluray\BD3D2MK3D\toolset\mkvmerge.exe"
    That means that the option to mux the final mkv has been turned off.

    To mux the files without having to recreate the projects, remove the REM in the __MUX_3D.cmd files, and double-click them.

    1. After finishing the encode and not completing the MUX to MKV file (so I can batch encode later).
    It's your error. You should not disable the mux. Just do not launch the encoding of the first movie before having defined the batch process.

  17. Great! I misunderstood that it would do the final encode for each file but this isn't the case. Thanks for the help with this.
