GH2 Flow Motion v2 - 100Mbps Fast Action Performance & Reliability for Class 10 SD cards

  • Checked the original .mts files on my Acer Aspire One D270 with Windows starter, the "rain" is not noticeable at all with Windows Media Player. BUT: It is noticeable in Windows in my uploaded mp4 which was reencoded on a MAC for attachment.

    So the error was finally baked in by Quicktime, and there is something going wrong with Quicktime on a Mac, probably in conjunction with Flowmotion?

    @karl You wont´t notice the rain in a still, because the contrast of the white lines is as weak as the banding (or solarization) effect of 8 bit. But they change rapidly, from frame to frame, this is what makes them noticeable. The greenish solaraziation around the dark areas ist stronger than the "rain" but less noticeable because ist is steady. Give those 2 stills a try, but even for me it was hard to find the stripes for marking. Again, the mp4 should show the error on Mac and PC. The original files should only show the error on Mac (OS 10.6.8) The images are two following frames.

  • @coors is there much difference between the two, I mean 1080i and 720...since there are some testers taking about 1080i not being a "real" 1080i and more like 720 up-sampled data ?

  • @peternap I don't recall the error message wording. If I see it again, I'll write it down and post it, here.

    @diafragma1939 I've been shooting in both 1080i and 720. Only the initial error, in 1080i, and trouble-free since. BTW, I'm using Transcend 32gb class-10 SDHC.

  • @karl. I just tested FM2-GOLGOP hybrid setting you created in 720p60 using Sandisk extreme 30mb and Transcend SDXC 64GB class 10 and it failed as soon as I started zooming with Panasonic 14-140mm lens. back to my Sanity-Sedna settings.

  • Hi All... I am brand new here and would first like to thank each and every one of you for all your hard work. Over the last day or two I have been reading up on the GH2 hacks. I want to try Flow Motion v2.0 but for the life of me I can't figure out how to download it. I assumed it was at the bottom of the initial post here. But all that is, is a graphic of a document. Am I missing something obvious here? Also can you point me to PTools 3.65d? I d/l 3.64 yesterday from a separate site, (that is where I found personal-view link) and tried a patch on my GH2, but it was unstable with my San Disk Extreme 45Mb/sec card.

    TIA

    Colin

    EDIT: OK, I just found out the link is now working where I expected it to. I guess it is only live as a member here. Awesome. Now to find PTools. :)

  • @rawmeyn: I think neither me nor bkmcwd make use of PAL modes, so I am not quite sure it would make sense to merge only very little tested 720p50 settings with FM 2.0...

    @Zaven13: The only class 10 cards I own are SanDisk 64GB 95 MB/s - so I cannot test others. But at least one user - jfro - mentioned in the GOLGOP3 thread that he had tested 720p60 with a SanDisk 30MB/s card, and it seemed to work for him.

  • @karl. Have you tried your hybrid setting with SD cards other than Sandisk extreme 95mb/s? For example Sandisk extreme 32GB 30mb/s. I am interested in a stable 720p60.

  • But that dosn't change my 720p50 problem in FL2 anyway;-) And someone else's 50/60 as i read.

  • @ rsquires "But it shouldn't change so badly should it" Sorry, but i think wrong whitebalance can transform human to purple Martian. If i want real good skin tones, i allways use a greycard.

  • I think I would have had it set to "Sunny" not auto. But it shouldn't change so badly should it. Anyone got a preferred setting for decent skin tones other than standard

  • @karl thanks I'll give that a go. I don't really use auto but I am pretty sure I didn't adjust the colour of the sunny setting.

  • @rsquires did u have white balance set to auto? Did u manually white balance based on changing or non changing light situations? That can have a big effect on skin tones.

  • @karl can you do that for PAL users too please? :)

  • @frame: Can you make a sreen shot and paint arrows to the beginning and end of one of those stripes you see in it?

    (I guess you are not referring to what is left from the bright CD covers when the picture goes out of focus - right?)

  • @Frame Yes, it’s there. I had a similar problem (much more pronounced) when I loaded a clip in QuickTime Player 7 once. It was a one-time glitch and I don’t remember what patch I used.

  • Since I was very satisfied with FM 2.0 in 24H/L mode, but could not live with the 720p60 stopping at random in complex high-motion scenes, I've created an amalgamation of FM 2.0 with GOLGOP3-13_standard settings for 720p60 (see attached file). Works very well for me - no more movitus interruptus ;-)

    Using this setting, I measured the following bit rates for the "moving leaves in the sun" shot:

    24H: ~110MBit/s

    720p60 SH: ~ 52MBit/s

    HBR 30p: ~54MBit/s

  • @karl No Plasma, even though I have one. Macbook Pro 15" with LED Display and NEC Multisync 232 for previewing. i see it on both screens. White flickering stripes with an angle of about 30 degree, the motion and flicker remind of rain. It could be a Mac-based decoding problem - and Fluid-Motion would be the first patch to show it - but then it is burned into the material after transcoding to mp4. This is what I did, so you should see something. I see it in the original mts as well as in the zipped mp4

  • @rsquires: Regarding your unhappyness with out-of-the-box skin tones: I experienced the same (regardless of what patch settting I used) with Auto White Balance - and my solution is to either use custom white balance or, when I am too lazy for that, I keep the AWB adjusted "two clicks down (towards magenta) and one click right (towards blue)", that gives me much better results with AWB under most circumstances (but especially in sunlight).

  • @Frame: I downloaded your clip and played it a lot of times in a loop, even single-stepped throught the frames, but I cannot see the effect you are describing.

    From your description, the effect sounds similar to a thing that Plasma TVs do to counter aging effects (kind of dithering bright areas), but I was watching the clip on a LCD. You do not coincidally use a Plasma...? :-)

  • Here is the file/clip of the rain-like effect...

  • Hmm, I have a nice "Tarkovski" effect: It suddenly seems to rain in my apartment. Just download & play the attached clip of the reply below and watch especially the left side, the flickering looks like fast snow rain close to the lens. Play the clip in a loop if you don´t notice it. Most visible in blurred areas. Shot 24H with 14-140, automatic focus on and shutter priority of 50 + auto Iso, and also with shutter prority & Iso of 160. Did not test manual mode, but loaded Sanity 5 again, the rain-effect is gone now...

  • @LPowell: you're a true genius! thank you SO MUCH for creating this.

    I have a small question to you. Basically, I do not care about the in-camera playback, so for 24 FPS I use: 1080p24 Frame Limit=9124000 (allows 1170KB I-frames) 1080p24 FB1=907838 1080p24 FB2=1200000 1080 SB=901252 Do you think this could only improve image quality and resistance to artifacts? Or could this be potentially worse somehow than your already fantastic v2.0? (I think Stray Death Chart is slightly better with those limits).

    Sorry if I'm just too fool :) and thanks again for this FANTASTIC work!

    By the way, for the first time 3GOP HBR (NTSC) became really usable! Very good & much better than with other GOP3 patches!!!

  • Just took a shot into the new Speedgrade and isolated some of the yellow in the skintones and pulled them toward magenta. Seemed to work very well. Would be nice to not have to do that though.

  • I tried version 2.0 this weekend and motion seems very good. Artefacting is minimal. However skin tones have occasionally been rather hit and miss. I don't know whether this was the settings I chose but I usually use standard at -2,-2,-2,-2, and haven't had problems before. I'm not laying blame but I am concerned. I don't see a great deal of skin tone examples here so would be interested in hearing from anyone else who has off skin colouring. I have added some examples. Especially worrying is the kind of grey dead look, and spurious jaundice yellow in some examples

  • Using sandisk extreme 45Mb/s had no problem in hbr/25p and extele ,recording a tree(almost filling the frame)..bitrate 55-65 using smooth (-2,-2,0,-2) with tamron 17-50... Same exactly scene in 720/50p mode i had to pull off the battery after 10-15 sec of recording... Formatted using sd formatter utility and i'll try again today.. PS i was using 1/50 and f/4 iso 160 and manual focus so no extra stressing the encoder...
