GH2 100Mbps Flow Motion Patch v1.0 with 50Mbps File-Spanning

Thanks - I'll try the new version.
I noticed the "High ISO limit removal" is not ticked.
Is there any reason for that?
I like to have the option for high iso's. Any danger in ticking it?

High ISO's are quite noisy and when used with Panasonic edge-sharpened lenses can overload the encoder with excessive bitrate. In low-light conditions, however, high ISO will work reliably as long as you take care not to overexpose the image sensor.
 
just test your patch for my GH2. but i got once fail save clip after rec around 4 min, my card is trancend class 10 16 gb, any setting that hv to change to elimate this problem ? maybe lower the bitrate ? btw the patch is great, thanks ipowell for your hardwork...

You may need to buy a faster card. Do a search on good cards to buy... Al
 
Any users think the color shift after you hit record has been severely minimized with this patch? Best I've seen yet.
 
It also seems that distortion correction on Panasonic Lumix lenses doesn't appear to be applied until after you start recording. The image in the EVF looks noticeably softer while framing the shot.
 
Lee, Big fan.. You have long advocated for the 30fps workflow and I'm sold especially with NTSC HBR. Please consider tweeking (or telling me how) Flow to optimise 29.97 HBR; it's good now but perhaps a hint on how to tune it "up" just a bit more. Most of the folks at Personal-View seem to concentrate on the PAL version. I currently use Flow as it is written having experenced too much noise with the various Driftwood constellations, I also realise that you are writing an all purpose patch but is there a small change I could make to goose it up a little more for HBR. My personal shrub of death gets up to video rate of 43

Perhaps your shrub is not gnarly enough? (Just joking!) HBR 30p turned out to be the most challenging video mode to optimize. Panasonic chose to implement HBR 25/30p as a variant of the GH2's FSH 1080i mode, and it's the most temperamental mode on the camera. The major problem is that many 1080i patches are shared with 1080p24 modes, making it very difficult to optimize both 24p and 30p video modes simultaneously while insuring failsafe reliability. I'm currently working on refinements to Flow Motion's Scaling and Blocking Tables that will enable the max bitrate of each mode to be individually optimized, which will hopefully provide significant benefits to HBR 25/30p modes.

Thanks for the link, royfel. I found that to be a clear and concise explanation of the drawbacks of shooting in 24p with digital cameras. For NTSC and web publishing, I've found that 29.97p offers a far less problematic workflow, and is compatible with both DVD and Blu-ray formats as well.
 
I apologize in advance but I'm tying to edit footage from this patch with PP5. I keep ending up with interlaced footage or so MediaInfo Mac and Quicktime tells me. If I create a timeline in Premiere Pro with the footage it creates an interlaced timeline (AVCHD 1080i 29.97 frames/second). I sent it to media encoder and it created a progressive file must of de-interlaced it.

Just wondering what the trick is to get Premiere Pro 5.5 to play nice with the MTS files. Read something about using AVC-Intra setting but perhaps that's for the other patches.

Thanks.

If you are shooting in HBR 30p mode (or in PAL 25p), the GH2 will actually store the footage in an interlaced MTS file that contains a progressively-scanned video stream. Unfortunately, these files look exactly the same as the camera's interlaced FSH mode files, which are genuinely 1080i60 videos. When importing the GH2's HBR 1080psF files into Premiere, you will need to use the Interpret Footage dialog on each MTS file and set its properties to 29.97 progressive. Premiere will then create the appropriate 1080p29.97 Timeline Sequence.
 
Thanks, I will try this. Any way to do this before I import into Premiere Pro.

Also what about FCPX, how do I tell it to "Interpret" the footage?
 
I just drag and drop my HBR footage into Premiere and edit. I dont see a reason to interpret each file since while I edit the files they look like progressive without any interlace lines going on. Only difference I see is that if I do the interpret footage thing the videos on the timeline gets a yellow bar instead of a red bar? But the image looks the same in any case?

When I export it I simply choose progressive scan and it looks good for me...
