    @producer

    you ever going to release anything for anybody else to try?

    @lpowell

    i'm sure you have mentioned it before, and i'm sorry if it has, but do you think HBR is the best way to shoot with FM? or does it depend on what you are trying to achieve?

    The lake of Posta Fibreno, is located by the village of Posta Fibreno, a small council of the Frosinone area in the Lazio Region. The lake is in a karstic terrain and rich in underwater springs.

    Waiting for clearer water in winter time I edited some test shots filmed this summer. In this period, warmer, slower moving waters increase the production of algae and allow it to accumulate in large blobs covering most of lake vegetation. Underwater shots are almost completely ruined by this mucilage, that constantly sticks to the port. We will be back in water in January with a gin clear water.

    For now, just a taste of this wonderful place.

    @GravitateMediaGroup Yes, I have been working on something new, but I don't have a projected release date yet in mind. It requires extended testing with a variety of SD cards, and I've fairly busy shooting lately. However, I'm not planning on increasing the bitrate of Flow Motion v2, as I'm convinced that 100Mbps peak is the highest reliable bitrate I can achieve with it in HBR and 720p modes. And with 24H mode, if I push it to to a much higher bitrate, it will no longer reliably span 4GB files on 95MB/sec SDXC cards.

  • GravitateMediaGroupGravitateMediaGroup

    can we expect anything new from "flowmotion" or is it all you want it to be? I was thinking maybe something with a higher bit rate or constant. If doing those puts the current quality of FM in jeopardy I understand.

  • peternappeternap

    @SAS Assuming you do any post work, I use Standard -2 across the board. You can up Saturation up one tick if you want. The hacked settings won't change still photo's. They will be the same as an unhacked GH2.

  • SASSAS

    hi. I flashed my SD card/GH2 with Flowmotion V2.2, just wondering are there some go to settings i should use for outdoor shooting at night time (video work) in a built up city area? and what about outside for stills/photo shooting wildlife in the day time? Thanks people.

    @LPowell I finally see what others are calling a problem with diagonal blotches or a rain effect using Flow Motion v2.02 on the GH2. While doing some green screen color swatch tests, I noticed this anomaly. So far, I have only seen it in After Effects CS6 and CS6.02. This anomaly does not show up in After Effects CS5.5 or Avid Media Composer v6.5 (or any video player software that I have tried). It also does not show up using Crossfire Variation 2 'Canis Green Screen' in After Effects CS6.0.2. I have been testing other patches in CS6, and the only on to show this behavior was Flow Motion v2.02.

    This all points to a problem with After Effects CS6. My operating system is Windows 7 Professional, and my Quicktime is version 7.7.1.

    Here are Vimeo links to files that I have upload showing examples (As always, DOWNLOAD first and then watch):

    Flow Motion v2.02, 24H, 1080p, Original MTS file from the GH2 -

    Flow Motion v2.02, 24H, 1080p, After Effects CS5.5 -

    Flow Motion v2.02, 24H, 1080p, After Effects CS6 -

    Flow Motion v2.02, 24H, 1080p, After Effects CS6.0.2 -

    Flow Motion v2.02, 24H, 1080p, Avid Media Composer v6.5 -

    Crossfire Variation 2 'Canis Green Screen', After Effects CS6.0.2 -

    P.S. Thank you so much for the discussion about lenses for video on the GH2. That was extremely helpful. I love the collection of Tokinas and Sigmas that I bought from your suggestions!

    @LPowell, @Mirrorkisser, @CFreak

    Thank you Gents for those explanations and considerations - contemplatively received!

    I remember reading the warnings about spanning and thought I understood it, but I haven't yet "lived" it - as CFreak did! I have two of those particular Sandisk cards which I bought quite some time ago - NOTHING else since has ever been mentioned as much for usually reliable GH2 high bitrate spanning, I've noticed. But yeah - under a tight timeline we might have to consider the greater reliability over a slight experimental quality increase even on the big screen. Frankly I'm not sure either which of the two competing philosophies on color resolution of both hacks in question would make a great and noticeable difference in quality even on the big screen, but I wish we could test that even beyond pixel-peeping!

    Do you realize that if it were possible to make the GH2 do a continual photographic burst mode of say 24fps beyond 1080p res for more than a second (my pocketable LX7 does 60fps! but for a maximum one second), we could assemble DCP movies beyond 8-bit gradation that would blow even the DCP people away! I got that impression talking to someone today who is connected to some of them who were checking out GH2 stills.

    But maybe we can blow them away with hacked video that is 8-bit (per color channel) - just VERY GOOD 8-bit! Unfortunately I can't find a field monitor with the size and latitude of the multiplex screen (LOL)! I'm not sure if a multiplex would allow us to test there. I'd still like to test if "sharp" translates to "cinematically soft" when things are scaled up so huge - some of the new screens look like IMAX to me! Or if a smaller art-house screen would benefit from a softer matrix. I'm guessing that GOP 3 Flow Motion or GOP 1 AN with a softer matrix makes for more fluid motion at least than the sharpest GOP 1 hacks - Inter having at least a few advantages over Intra. And, a least by staying in the 8-bit realm, we can more closely see what we're getting with standard 8-bit display devices. But I think I may be preaching to the choir - sorry.

    I appreciate any more thoughts on this.

    A re-shoot might be delayed until December but I'll keep you posted one way or another - probably can't say too much until after the shoot though.

    -- Stacy.

  • LPowellLPowell

    @SMuller Thanks for considering Flow Motion v2 for a big screen project, I'll be very interested to hear how your producers respond to it. If you could post any of your test footage comparing the pro camera with the unhacked GH2, it would be most helpful

    On the topic of spanning, FM2's 100Mbps 1080p video modes will pack a little over 10 minutes of video into each 4GB MTS file. If you need to shoot longer takes at highest quality, I'd recommend using 64GB 95MB/sec SDXC cards for reliable spanning.

  • david_ddavid_d

    Dear @CFreak !

    Thank u a million for your details. That helps me so much. To be honest, i never got "spanning" issues with FlowMotion, but I always got some with AN even with SDXC Sandisk 32GB card.

    I mean, it always fails after 4 or 5 minutes.

    Thank you again!

  • CFreakCFreak

    Why a 4 GB limit on file size? That's the limit of the SDHC card's "FAT" file structure. My SDXC card only liked the "exFAT" format.

  • CFreakCFreak

    @david_d ...meaning that if your recording needs to go beyond 4 GBs on the SD card and the speed of the card is not fast enough to span (close the current file and start a new one, while continuously recording) your recoding will stop. Just stop all by itself.

    If you are not staring at the screen you may miss it. If the camera is unmanned, you will miss it, and when you return to the camera you will wonder (after thinking oh, Sh*t!) "did I forget to turn the camera on?" No, your camera/lens/card/settings combo failed to span and it might screw you over for your project. There is a lot of discussion about spanning and card on the threads for each different setting. Then you want to test it like crazy for yourself before taking it on a paying job.

    It is often said that spanning is no problem on the most expensive Sandisk 64GB card, but, as 64GB cards and up are SDXC cards, they introduce a new, pretty bad problem, if you don't know what you are doing or are in a rush and turn the camera off directly after a spanned recording, the camera when turned back on will no longer be able to record to the card. I know what I am doing and sometimes am in a rush so I refuse to buy another SDXC card and try not to chose a setting that requires them for spanning!

    The more you ask from your camera (via the hack) the more it will ask from you (and your time!).

  • MirrorkisserMirrorkisser

    @david_d spanning means that you can record longer files. Otherwise there is a size limit and you can not record beyond a certain amount of time...

  • david_ddavid_d

    Der @Mirrorkisser : what does "span" mean ? I'm sorry but I don't understand well this notion. Thank you!

  • MirrorkisserMirrorkisser

    @Smuller: i would be careful with the AN settings. They produce very nice picture, but they do not always span, in case you need that feature. For your work i would either stick with SEDNA, FLOWMOTION, VALKYRIE 1.5b.
