    720p / SH Lumix 7-14 and not compatible with Flowmotion v2.2 :(

  • dado023dado023

    @omnidecay

    that card is UHS. Does GH2 utilize UHS write speed?, because i couldn't find it anywhere in spec GH2 support UHS mode.

    @rsquires

    Is there a shorter GOP setting for Flowmotion in 720p PAL mode?

    Good question. During the development of Flow Motion v2, I tested a variety of 720p patches using both 3-frame and 6-frame GOP's. One of the inherent complications in optimizing 720p modes is that they share several bitrate settings with the 1080p HBR/FSH modes. In order to achieve reliable operation with a 3-frame 720p GOP, I had to tweak it in a manner that produced sub-optimal results in 1080p HBR modes. Using a 6-frame 720p GOP allowed me to optimize both 1080p and 720p modes to operate reliably at 100Mbps peak bitrates.

    Yeah I mean its close at write: 15.8MB/s but it should be working. After a flash did you format the card? If format doesn't work the only thing I can think of is flowmotion going about the 15.8MB/s mark on the high end. I dont know which transcend card you have but the one you want is:

    http://www.amazon.com/Transcend-Speed-Class-Memory-TS64GSDXC10U1/dp/B00AFTV3FC/ref=sr_1_2?ie=UTF8&qid=1365831412&sr=8-2&keywords=transcend+64gb+sdhc

    I use the 32gb version of the card above and its always worked great for me. I usually get around 304mbps on writes.

    @omnidecay

    i have TRANSCEND 64GB class10, test results: READ: 163.8 Mbps WRITE: 126.9 Mbps

    It is not fast as SanDisk, but it is still one of the fast cards out there.

  • omnidecayomnidecay

    @dado023 100mbps is only 12.5MB/s. What kind of card are you using? 24H spans for me on SanDisk 30MBs and 45MBs. Maybe speed test your card and see what is the avg write speed.

  • dado023dado023

    tested on 24H with Instantaneous Death Screen, but fails, it writes with more than 126Mbits after that i get speed problem card, and my card can go max 130Mbits without crashing.....on 24L everything is fine

    Can FM2.02 for 24H mode be somehow limited to not to go over 100Mbits?

  • omnidecayomnidecay

    Tested SanDisk 32gig Ultra 24L - spans and records around 55-60mbps. Really, really awesome patch!

    Is there a shorter GOP setting for Flowmotion in 720p PAL mode? I am shooting kids sport and for the most part Flowmotion 2.02 is very good. However on very fast motion there is a muddy look to the fast moving parts of the image which is not surprising considering that each frame is very different. So my question is, is there a stable 3 GOP setting or lower, or was this jettisoned because of stability issues.

    Thanks in advance

    Hi,

    I have just bought my GH2 and discovered this hack. Very nice results, i can see on the videos. I would like to ask a few basic technical question, since i am a beginner with my camera and with this hack as well.

    After i succesfully installed it, will the camera menu reset restore my original firmware? or i can reset the camera in the menu settings without affecting the hack?

    I would like to use it for full HD and 720p 60fps (for slow motion). What camera settings should be set in Movie mode for achieving the best results? Should the High bitrate option be turned on, to achieve the bigger bitrates?

    How can i achieve the 80% slow-mo what the hack offers?

    Thank you very much in advance!

    Flowmotion V1, I'll testing new patch this weekend ;-)

    @notjackson

    When I transfer the footage with Log and Transfer in Final Cut 7, it says the bit rate of the clips is around 13-16 MB/s for a 24H clip. Is this what I should be aiming for?

    You don't need to aim for any particular bitrate - the GH2 will automatically use only as much bitrate as needed to record at the quality level that Flow Motion v2 is designed to deliver. As others have pointed out, 13-15 MegaBYTES/sec = 104-120 MegaBITS/sec, which is the highest bitrate FM2 can deliver in 1080p 24H video mode.

  • notjacksonnotjackson

    @coors yeah that's what I thought but the data rate seems to be lower than my t2i... I guess that's just how it is. thanks

  • coorscoors

    1MB=8Mb...so multiply those numbers by 8. I believe that's what Nomad was saying.

  • notjacksonnotjackson

    @nomad I'm not. the data rate is listed as megabytes. Can someone help me out here?

  • nomadnomad

    Don't confuse megabytes and megabits…

  • notjacksonnotjackson

    This is my first hack with my GH2, just got the cam a few days ago. However, although the installation process went fine, I'm not totally sure if FM is up and running. When I transfer the footage with Log and Transfer in Final Cut 7, it says the bit rate of the clips is around 13-16 MB/s for a 24H clip. Is this what I should be aiming for? Thanks

  • mastroianimastroiani

    @Meierhans thanks. I will try that!

  • MeierhansMeierhans

    Set TV - Out to PAL, insert empty SD card, switch cam to HBR.

  • mastroianimastroiani

    Hello, can someone tell me how to activate/use 25P on my GH2 camera while using FlowMotion? Thanks!

  • debinatxdebinatx

    @LPowell I'm a little late to the GH2/GH3 game, having been a Canon user for awhile until my Mark III began overheating during interviews lasting longer than 15 min. (Ugh.) Finally sold the Canons, purchased a couple of Pannys and took my GH2's with FM2 installed out in the field today. All I can say is wow. It's phenomenal, Lee. I've had less than ideal results with other patches, but FM2 was stable and spanned beautifully on a Sandisk 64GB 95mb/s card. Thank you for your work and for sharing it with us.

    Some grabs from a spec industrial/commercial shoot recently. Nikkor 35mm f/1.4 lens and ISO 160, if you can believe that. It was really like having the sun indoors in this Honda service center, it was so well lit.

    @tetakpatak, thanks for the explanation
