  • @driftwood It's here, the denser chart is the man http://personal-view.com/talks/discussion/comment/17820#Comment_17820

    This is the graph of bkmcwds patch running on the shot that makes my SD card give up. heh, fucking hell, Please someone shoot some similar footage with a card that can cope, similar as in same size B-Frames and avg bitrate.

  • @Botvinic I may have to raise the bitrate a tad to get this stable
  • @Stray Where is this latest chart youve made? Sounds good.
  • *UPDATED RELEASE* Improved PAL 720p50 and 1080i50 at lower bitrate - 128M !!!! - and an attempt to fix the artefacts.
    @Botvinic Can you try this? thanks.

  • @bkmcwd Its a great patch, but too rich for my SD cards under some situations. Shooting high motion and details, (trees in a very strong wind) I get write errors every time (with an Extreme Pro card, and some extreme cards). Really need someone to test this with one of the older Extreme III cards. Indoors it holds up extremely well, and also with either less detail or motion I have no problem with it. It looks beautiful btw.

    Get what you're saying about my dense deartchart. Its good to see your graphs to compare it agains Pappas deatchart. My new chart definitely pushes it a fair bit more. Failing my chart is not, I feel, a reason to completely discard a patch, it is more intense than anything you're likely to shoot. However, a high motion test is worth doing too to clear a patch. I may create a less detailed and animated version of the chart in the next week or so.
  • But why such a bad picture? Bitrate was around 60 Mbps in the file. Maybe not enough speed card?

    This is much worse than with my firmware to 32 Mbps!

    I did a bitrate 32 Mbps and gop12. I-Frame still contain artifacts. I do not understand.
  • ver 2 will have lower bitrate
  • @driftwood
    It is possible to make settings with lower bitrate (50-100 Mbps), AQ2, Gop 6-12 on the basis of "smackmygopup"?

    PS I tested the "smackmygopup" and 50p picture has large artifacts.

  • I'm getting card read errors left and right using 80% on sandisk extreme 30MB/s 8GB and 32GB cards even when freshly formatted.

    what could i be doing wrong?
  • @driftwood
    Great work. I can't say enough as to how helpful you have been with your rigorous testing and (seemingly hourly) settings files. Just wanted to say thanks-
  • @proaudio4
    Thanks for your comment!
    Strictly, I referred to my favorite driftwood's 132M 3GOP and made this.
    If it was right since 132M AQ2 was not able to clear Stray's extream dense chart test perfectly as written before, it is practical use within the limits, and I thought whether frame size could be enlarged to a slight degree in low light scene.

    Though regrettable, this cannot clear Stray's chart test perfectly.
    As stated above, I am checking that the stress by Stray's chart also changes with the size of a screen.
    Probably recording will stop at the test in the state to which chart was expanded most where glaring green, in several seconds.
    However, in the test recording the whole chart while moving flickeringly, it lasted for 2 minutes only once.
    All my tests are made with ISO3200, 1/800ss.
    This is because 1/800 can apply stress most in my environment.
    However, since I do not understand the level of an indispensable stress as told before, this setting may be unable to clear your stress test perfectly.
    On the other hand, I think that it can be well used since this clears Pappas chart test repeatedly.

    @sohus
    Thank you for your info.
    This setting was not able to clear extream test, unless my test also used SanDiskExtreamPro(45M).
    It was useless even at SanDiskExtream(30M).

    @JDN
    Please leave it to the maestro driftwood.
    Since I am a person following all the members back. :-)
  • @PerryWilson I just did a lot of research and stumbled on a piece of freeware called (x264 encoder) You can export your final project by selecting this encoder and it will do a way better job than your NLE generic encoder, also you can convert your footage let's say with 5dtoRGB with this encoder before importing to your NLE I hope that helps Perry. The choice is yours pay for the MainConcept Encoder 5.1 which I heard is amazing, or use X264 freeware they are both amazing from what I read..
  • @TrackZillas IDK what your talking about to be honest... I was about to ask what the best quality I could export was... because im pretty sure the H.264 ive been using out of after effects is sucking it up...
  • @peterosinski
    I've used the 176mGOP1 patch at 80% without problem. The slower shooting speeds (160%, 200% etc) should not be a problem.
  • hey @driftwood

    does the intra patch support 80% and 160% slow motion?
  • @PerryWilson I know Driftwood's patch is bananas.. I got a very important question Perry the (mainconcept codec suite 5.1 Plug) is main purpose is to export video to a final file format right, it does not do anything to the footage when ingested? Finally when exported does it really preserve quality in the final output? Let me know as soon as possible cause I'm thinking on getting it for my system.
  • @driftwood Your the F...ing man, can wait for the improvement..
  • WOOOO!!! the fire stuff I shot looks amazing on 24p... I cant wait to shoot it on 60 :))) Illuminati Cigar company is going to be amazed when im done with there new promo... all shot on DRIFTWOOD BABY!!!! WOOOOO
  • or will the 108024p be getting better to?
  • so when you do the 72060p setting 108024 will remain the amazing GOP1 setting we have now (QuantMe, IDK the rest)? and 72060p will be 226m?
  • Before anyone asks. 720p60 is being tuned at the moment...

    Nick
  • Here it is GOP1 PAL freaks. 1080p24 176M, 1080i50 & 720p50 226M 'SmackMyGOPUp' patch version 1. I expect to increase quality overall over the next few days and experiment with lower buffers. This, for now, works and is stable on the death charts. The 720p is particularly close to i frames in the stock setting but this contains ALL iframes - no 23 P low frames as found in the stock. Its high on the bitrate but thats the way it is with GOP1 :-) Enjoy!

  • @JDN The status is 50p first, 60p next. I have a nice 720/50p GOP1 but every now and again it goes unstable so still working on it.
  • @sohus, yeah, but if you can hold off you may also wait for the results of driftwoods SD card showdown... or pick up a 16 gig SD extreme to keep you happily testing in the meantime.

    @bkmcwd & @driftwood -- what's the status on 720 60p or even 1080 60i low GOP? I'm shooting some mixed martial art fighters training for a promo Thursday and would love to try something out (I can post results) -- obviously this is a situation where 24p is probably not the best option so would love to try out a hq low gop patch that does 60 frames either i or p.

    (PS Don't care if it is unstable -- this is only a test shoot; real shooting won't happen for another week or two).
