Driftwood Quantum X Settings, Series 1: v3b Rocket - v4b Orion - v5 β Pictoris
  • 1019 Replies sorted by
  • Hi Driftwood.. I just want to know if, The softer Matrixe mean a smoother image....more closer than a film look

  • i'm not familliar with mosquito noise can you explain me what that is? I filmed a well lit place went to a darker, filmed lots of textures and followed my rabbit around :') =) i didn't notice anything wrong

  • What was the image of? I just made a slow pan from my office couch to the desk, both illuminated by a separate light, shadows in between, and 24p was great while 25p was loaded with banding and mosquito noise, the latter especially on my laptop screen displaying a text doc. Quantum rocket at 25p seems to me as if it cannot handle the information recorded by the sensor. Hence my idea that using the efficiency of a long GOP setting for 25p might solve the problem.

  • I did some quick tests and really have no problems with 25p i started laughing when i saw the image of pure goodness, sandisk 16gb 45mb/s leica/panny dg summilux 25mm 1.4 was my gear

  • I filmed a bit tonight with quantum rocket (just boring stuff at my office) and 24p looks great! My impression though is that 25p is significantly worse and if I understand the various threads regarding 25p it's tough to get 25p to be as good as 24p, at least in a GOP1 or GOP3 setting. My problem is that I am intending to am interested in using the GH2 as a potential A cam on a project for a broadcast project for PAL countries. So my admiration for the formidable work of the short GOP developers turns into frustration when I see that the potential quality of the GH2 is lost when having to film in 25p. I could perfectly live with a long GOP setting if it spares me from macro blocking, mosquito noise and too much banding. My filming style is mainly tableaus anyway, so motion is limited to the motion within the frame. I am willing to test and report, but I would have to know where to start. If some of the more knowledgeable people could provide some settings as a starting point I would be very thankful!

  • @mozes whhy is your image flashing sometimes? I don't have that on my footage..

  • Interesting lens combination you got there @mozes, its not too bad with that Tele setup...

  • @Chhatrapal Nice tests, much appreciated. Sure try some settings out - feel free - report back - its always good to know what works - I havent the time to try out everysingle poss combination at different bitrates. :-)

    @Hallvalla I know what you mean, I'm getting stunning grabs from this setting.

  • Hmmm...lost the attachment. Trying again.

  • @driftwood So nice. Random frame grab from today. Love the detail and the shadows are amazing.

  • @iLovPieNCake Wrong setting/ firmware or poor card. recheck everything, youve fucked up somewhere I think. Actually, I spot the rogue P frame in your streamparser which indicates you havent set encoder setting 1 720 =3 and encoder setting 1 1080 = 1. Redownload 'Quantum X v2 Rocket' you must have changed something.

  • @driftwood Re: "NOTE: Do not low level format hi-spec cards like the 64GB 95 sandisk." -> Does that also apply to the sandisk 16GB/45? Was prepared to low-level format all of my cards (sandisk 16GB/30, 16GB/45, 64GB/95) with SDFormatter. Thanks for that info +++ as well as your supremely awesome endeavors +++

  • GF2 User Here. I have a 16gb PNY Class 10. For some reason 720p doesn't produce any B-Frames resulting in choppy footage. Stream praser Image attached. But 1080i works just fine at a higher bitrate?

    Oh, I just loaded the settings and flashed then reset all cam settings.

  • @Driftwoods I look at the monitor and I really can't believe my eyes! Did I really shoot it with this cam?? It is a joy to see such a quality and beauty :-) Thank you.

  • Some Quick Tests

    Card Sandisk 32GB 30Mb/s

    Lens canon FD 50mm F1.4 @2.8

    ISO 400

    Film Mode smooth -2,-2,-2,-2

    Downloaded 720p file this video and looped

    Test one 24H did not span nor played back in the camera

    Test 2 720p50 SH spanned up to 13 mins and stopped by me, there were three files on the card and played back in the camera as single file. Screen grab of only first file

    Test 3 HBR 25p spanned up to 12 min and stopped by me

    Test 4 1080i50 could record up to 2 mins, did not played back in the camera

    720p60 card writing error in both SH and H

    @driftwood can i increase bit rate of 24L setting to say 80mb/s as quantum 100 24H was spanning 100mb/s on my sandisk 32gb 30Mbps card in almost all type of condition. Will shoot some real world footage 2marrow

  • @liverto Well I've reformatted and tried again, 24H with my 32gb/95M card, and v2 spans just fine. I tried ETC and normal modes. So perhaps it was a format issue. I'm still finding that the file sizes are quite manageable (12 min/4 gb).

  • just my first shots with Xv2.
    Nothing special, shot in 24p, 25p and 720 50P, with and without tele2
    Renderd with Avid's DNxHD codec 1080p 25fps.
    All done with iso 320, shutter 1/50, nostalgic all in -2, and whitebalans = clouds
    Last shot is 720, iso 320, shutter 1/200 and 1 stop under illuminates. (tele2)
    Lens is a Olympus M. Zuiko Digital ED 14-150mm 1:4-5.6
    Completly zoomed in and parts included with tele2

    Ps, card is a sandisk extreme hd video 32gb 30mb/s

  • @Adde Shaking doesn’t necessarily stress the encoder. Shaking creates motion blur, which sometimes reduces detail. Shoot a death chart and make tiny, slow panning movements. Alternatively, create an animated sequence out of two drastically different death charts and loop it. Then you can have the camera sit a tripod unattended.

    Yet another (although not as effective) method is to shoot with the highest ISO to introduce randomness via noise.

  • I've been saving up for a Sandisk 64GB card and just wondering if anyone has ever tried Transcend UHS 16GB card? I remember reading somewhere that they have speeds up to 85Mbps. Since the price difference doesn't seem to be that much from Sandisk 95mbps 16GB, I'd rather continue saving up for the Sandisk. Just wondering if anyone has tried them out with the hacks, if so, how do they fare compared to sandisk 95Mbps and sandisk 30Mbps

  • @Adde Its adaptive yes. @killagram in-camera format is best. NOTE: Do not low level format hi-spec cards like the 64GB 95 sandisk.

  • @driftwood do you feel a quick format of the SD card is sufficient for Quantum X v2, or is a full format (yet somewhat time consuming) preferred?

  • Don't get it right now... Recorded 1 minute and 12 seconds, the file is 251 mb and the bitrate according to windows is about 31080 kbits per sec. Iso 1600. Aimed the camera against my computer monitor and shaked it to create more stress...

    This patch adapts itself to the detail I guess?

    Is this patch reliable for a music video shoot?

  • By the way, QuickTime Player 7 plays back MTS files without a hitch (if you let them load completely first) with Panasonic’s AVCCam Importer QT plugin. No dropped frames. I can also use Quick Look right in the Finder. I’m on a mid-2010 MacBook Pro.

  • I had experienced some problems earlier on a GF2. The camera would record, but when I played it back in the computer, the footage would fall apart. I found out that I had loaded the settings with the initial PTool release, which had been later upgraded. You might want to ensure that the PTool you're using is up-to-date. Patch works well for me now. Using Sandisk Extreme 8gb class 10 and manual lens.

  • @Oedipax Pleasae remember this Quantum X (v2 Rocket) will push your card to the limit on detailed shots - that's why I swear by Sandisk Extrme Pro cards - but thats my personal view. Make sure before a major shoot, you reformat cards too.
