    @LPowell... hey! whats up...

    I have a question, I am trying to get a patch to work properly in 720p60 mode, and noticed something in flomotion 2.02....

    i noticed that you have altered 3 values; which are unaltered by other patches, they are:

    Limit 63000=70560

    Limit 47700=53420

    Limit 15300=17140

    I cannot seem to track down what these are for.... do these values affect 720p60 mode in any way??

    thanks chief.

    vibrant colours. did you grade the footage?

  • valpopandovalpopando

    @Kazuo yes on Final Cut Pro X

    These are internal AVCHD settings. In Flow Motion v2 they're increased to enable the encoder to handle larger frame sizes. For more information, ask Vitaliy to give you access to the following wiki pages:

    What are the best SD cards for flow motion v2.02 on a GH2? I have tried a scan disk 32GB class 10 with 45MB/s and a scan disk 32GB class 10 with 30MB/s. Both would stop recording on there own and the 45MB/s would not even log and transfer into Final Cut 7. I am trying to record over 30 minutes continuously.

  • MirrorkisserMirrorkisser

    @mchristian: thats weird the sandisk 45mbs works like a charm on flow motion, spans every time...

    The 64gb 95mbs are the best and also most expensive cards...

    @clebervb "There is a artifact in the vertical in some scenes. I shotted in: 1080/24p (24H) Panasonic 20mm lens Shooter: 1/50 ISO: 160 - 320 Smooth (all -2) Final Cut x"

    in 1080 on Youtube, other than the reflection of you in the chrome, I did not see a real problem :-)

    The many shades of red on the coffee machine may have generated some kind of artifacts. Red is the most difficult for video to reproduce accurately. It has to do with it's place on the ROY G. BIV color spectrum having the longest visible wavelength.

    As far as I know all video has this problem, across many cameras, not just the flowmotion patch on the GH2.

  • MChristianMChristian

    @mirrorkisser: ok thanks. I'll try them again. I am shooting in 1080 24p on high. Does that make a difference?

  • MirrorkisserMirrorkisser

    i use the same settings, 99% of the time i shoot 24p in the same settings...

  • livadalivada

    Hi I have problem. I use fm2.02 and 2.01 in PAL mode. use HBR and my GH13StreamParser 2.7 always say this:

    ile: C:\7\00003.MTS Size = 84.922.368 Bytes (442.304 Packets) Stream: Max Speed = 105.526.700 bps Mode = 1080/50i PCR Timing Interval = 0,095 seconds Clip Time = 0:00:14,56 Average Total Bitrate = 46.660.641 Average Video Bitrate = 45.077.131 Average Audio Bitrate = 235.516 Average Other Bitrate = 1.347.993 Max GOP Size = 1.053.888 Bytes (8.431.104 bits) Video Frame Size (Min/Ave/Max)= 16.512 / 229.730 / 602.688

    WHY 1080/50i ?

    i wont 1080 25p mode :(

    I try othe 1 gop hack and stremparser say this :

    File: C:\7\00002.MTS Size = 44.144.640 Bytes (229.920 Packets) Stream: Max Speed = 130.006.300 bps Mode = 1080/25pH (Native Hack) PCR Timing Interval = 0,095 seconds Clip Time = 0:00:11,48 Average Total Bitrate = 30.762.814 Average Video Bitrate = 28.823.740 Average Audio Bitrate = 235.163 Average Other Bitrate = 1.703.910 Max GOP Size = 256.128 Bytes (2.049.024 bits) Video Frame Size (Min/Ave/Max)= 123.456 / 146.687 / 256.128

    this is 1080/25p - this is ok but this hack total unstable. I want powel hack with 25p not 50i mode.. help me

    thx

  • LPowellLPowell

    @livada What you're seeing in Stream Parser's report is evidence that the GH2 fails to tag HBR files with the correct metadata to indicate that they contain a progressive video stream in an interlaced wrapper (aka psf format). As a result, GH2 HBR files are formatted in exactly the same way as GH2 FSH files, and Stream Parser has no way to distinguish between them. As an aside, the Panasonic AF100's 1080p25 and 1080p30 MTS files are correctly tagged by the camera, and can be properly identified as progressive video streams stored in interlaced format.

    The GH2's failure to properly tag HBR files creates a post-production hazard when shooting in 25p or 30p. After importing these files into a video editor, you must make sure that the footage is correctly interpreted as progressive rather than interlaced. In Adobe After Effects and Premiere Pro, this is done by setting Separate Fields OFF in the Interpret Footage dialog. If you don't take this precaution, you may see spurious interlacing artifacts in HBR footage.

  • livadalivada

    @LPowell Means the video is progrsive? only idicate in metadata wrong? I use sony vegas and in option i dont use deinteralce and all ok ?

  • livadalivada

    I even forgot this: how is it that the Driftwood Hack GOP1 metadata displays 25p native normal

  • LPowellLPowell

    @livada Yes, the HBR video stream is progressive, regardless of what the embedded metadata may indicate to an analysis tool.

  • livadalivada

    @LPowell Thx

    @mirorkisser, @mchristian: thats weird the sandisk 45mbs works like a charm on flow motion, spans every time...

    Yep but only the Sandisc 'Extreme" version not the "Ultra"

  • clebervbclebervb

    @CFreak Thanks! I`ll study what you said. And yes,I always forget my reflection on this kind of scene! lol

  • valpopandovalpopando

    Vimeo's compression does not perform well the rain LOL ! the original one is much more detailed

  • clebervbclebervb

    One more video with flow motion 2. Hope you like.

    I realize that the artifact (lines running in the vertical) is my iMac.

  • bugiltbugilt

    FM 2.02 Did some stabilization in post. Wasn't optimal for most of the shots, but it was just more practice.

  • MChristianMChristian

    @mirorkisser, @rambo: Yep but only the Sandisc 'Extreme" version not the "Ultra".......

    Ok cool, I have been using the Scandisc Extreme version on both cards. I have read that the UHS-1 cards have technology that causes problems with spanning. It all is a little confusing. The price doesn't matter, all I'm looking for is what exact card works best with flow motion 2.02 while in the 1080 24p mode at the highest bit rate. It is my goal to record till the card is full without the camera stopping. If there is a card that works best I am all ears. Thank you.

  • peternappeternap

    @MChristian If price doesn't matter, just use the Sandisk 64gig 95mb card. I use them with everything in the GH2 including Flowmotion 2.2. That said, I've never had any trouble with FM. That and Sanity 5 are just well designed settings that aren't that demanding.
