    Tried out GOP3ZILLA v2.12 on PAL mode with Samyang 35mm and Sandisk 32GB 95mbps. It stopped recording in 24p. Slow panning in a slight drizzle and over grass and plants. All other settings worked beautifully. Same thing in NTSC. All other modes work well but stopped at the exact same spot when in 24p. I've attached a screen grab of where the video stopped recording.

    Does towis modyfied V2 and bkmcwd V2.12 beta have both the same settings for PAL?

  • chromekodachromekoda

    YEEEE !!!!! First impressions... bkmcwd GOP3ZILLA_V2.12_BETA.zip seems to work with my configuration in all modes very well. I am shooting everything in PAL mode....

  • bkmcwdbkmcwd

    @towi

    Please check, although I think that it is probably OK now. :-)

    @ someone

    Please check especially NTSC 60p. :-)

    balazer, Re: MPC-HC interlace settings... I set MPC-HC up to use LAV filters (external filters) and configured LAV Video Decoder to use "Treat as Progressive" under "Settings for Deinterlacing". The latest version (0.50.1) supports ATI hardware acceleration via DXAV2 (native). Works the ballz:-) Thanks for pointing me in the right direction to get interlacing working properly in MPC-HC.

    @towi

    Thanks mate! :-)

    Although I am adjusting NTSC now, since I have an appointment with my son today, it may take time more.

    Your explanation about my settings is perfect. In addition, I have raised one more and "natural" as a safest and economical setting.

    @chromekoda

    Thanks always! :-)

  • mingerminger

    @towi thank you for your immediate answer.

  • StrayStray

    Yep indeed, I have to shoot HBR all day in a couple of weeks, and I can't praise you highly enough for the changes. I use GOLGOP13 for everything 24p pretty much myself.

  • towitowi

    @Stray

    yes, the changes are all in the GOP related settings. But bkmcwd is still working on the NTSC mode tables... so be patient :-)

  • towitowi

    GOLGOP13 is actually aimed at lowlight shooting as the noise looks very, very smooth. In comparision to GOP3ZILLA it produces much larger B-Frames (in all modes) ... at the price of much higher bitrates beeing utilized (and therefore larger filesize). I also use GOLGOP13 in daylight as motion looks somewhat smoother. But GOP3ZILLA spanning in HBR/25p mode on 30MB/s cards is definitely a keeper for me!

  • StrayStray

    @towi What are the changes to GOLGOP the same as the ones made to GOP3ZILLA ?

  • mingerminger

    Please help me out: What was the intension of GOLGOP13?

  • towitowi

    Well, I would call it GOP3ZILLA :-) It's bkmcwd's setting after all. I've just optimized the GOP tables for PAL modes. I have no buffer analyzer software, though. I need feedback from bkmcwd. So it takes time. But it seems we are getting close. GOLGOP13 looks georgeous! (soon to be released). GOLGOP13 doesn't span in HBR/25p mode, though.

  • mingerminger

    @towi How would you call this setting? "Iron Sky"? Again this grew better. How far can you go?

  • balazerbalazer

    Bonzi, Media Player Classic Home Cinema does a great job using its built-in filters. The problem is that it uses DirectShow, and any random DirectShow filters installed on your system could be doing the wrong thing for interlaced video. (the wrong thing of course being the right thing: de-interlacing interlaced video that doesn't need to be de-interlaced) Make sure that all of MPCHC's internal filters are enabled, and then check to see which filters are actually being used during playback. If other filters are being used, you'll need to reduce their merit or unregister them. It's a little more complicated than I care to talk about here. Google probably has info. Personally I use MPCHC and ffdshow tryouts.

  • towitowi

    720 what? 50 or 60? Which card?

    720p50 survives EVERYTHING here even on my old class 6 SanDisk20MB/s. I am talking really heavy torture tests with ultra sharp lenses ...

    Don't forget to reformat the cards when a new patch was installed ...

  • chromekodachromekoda

    =( , 720 freezes everything ... maybe tomorrow :) . Thanks for fighting... bkmcwdrocks !

  • towitowi

    Updated version of the modified GOP3ZILLA

    • improved 720p50 (thanks to @bkmcwd )

    • stable performance on SanDisk 20MB/s cards (in all modes / camera set to PAL)

    • spans in HBR/25p mode on SanDisk 30MB/s (and faster, of course)

    Preliminary setting aimed at PAL users. bkmcwd will release a final version for all modes soon.

    attached a screenshot of a 16GB SanDisk 30MB/s card. First clip was a short test in 24H. The other 4 clips are HBR/25p spanning until the card was full. Average bitrate utilized in this spanning test: 75M. Streams look healthy all over the clips.

    Hmmphh, sorry,I had wrong settings (they were 1080)... 720 freezes the camera immediately with GOP3ZILLA_modified.zip with my cards.. Motion recording was cancelled due.. The battery has to be removed to get it back to working condition.

  • konjowkonjow

    great news towi, cant wait to test new pal option... not sooner then tuesday:(

  • chromekodachromekoda

    Thank you towi, GOP3ZILLA_modified.zip seems to work pretty well both hbr and 720 in my pal cam. SanDisk 30 MB/s. So far it seems to be the best for 720 for me... all the others settings have freezed the camera. Great !!!

  • mingerminger

    @towi Thanx for your efforts in the 25p arena. It really seems that you are succeeding. My 25 minutes test run outside went fine. I was using a 32GB 45mbs SanDisk and a manual lens at aperture 5.6 and ISO 320. Keep up your good work.

  • towitowi

    @Bonzai

    there's still something wrong (with the settings in HBR/30p mode) ... when you look at the moving blades of grass on the left side you'll notice that the background (the little stones in the flower bed) is also "moving" ...

    blazer, bkmcwd... Interlace mystery solved. It's a video player issue. Thanks blazer for taking the time to analyze the video file posted to Vimeo. I was a VLC fan a few years back but it tended to be buggy. After evaluating the MPC-HC platform I never looked back. In my case the Windows Media Player also plays HBR 30P files with artifacts however VLC plays 'em back just fine - including those posted by bkmcwd. And yes bkmcwd, your screen capture isnot interlaced :-)

    @towi

    I confirm that @balazer says it in the second post of Cake's thread (I reported it to you a couple of pages ago on this thread).

    If your theory turns out to be true I think we'll see big improvements in a lot of settings' spanning capability.
