  • So where do we stand on all of this? Is HBR25p solid in PAL land?

  • Thanks inqb8tr! I will try!

  • @fran Yes, that's the way.

  • @inqb8tr Aha, ok. So I should start a progresive projet 25p, and then get my GH2 footage in the browser and interpret it like true 25p. If I do this the Time line won´t force me to render. That´s right? I think in final cut would be necesary to use Cinema tools and confrom to 25p. I will do and will say if it works. Thanks inqb8tr

  • @fran It is 25p wrapped in 50i. You need to force your NLE to treat it as 25p. In premiere you use "Interpret footage". In FCP (not sure about fcpx) you Conform footage using cinematools

  • but, how lie to the NLE? for example FCP? droping the footage on 25p TL?

  • Had the same problem myself found this answer on this forum...

    I'm looking for a 1080/25p patch and I tested a few of it in HBR mode like LPowell Flowmotion 1.1 or Quantum. When I insert one clip recorded in HBR in the StreamParser, the stream mode say that it is 1080/50i, and this is usual as can I view in the users screenprints of another patchs. Adobe Premiere (for example) don't recognize the progressive mode, an says that is interlaced. Anyone can help me? Thks

    nomad July 14 You'll need to "lie" to the NLE. HBR is progressive footage (i.e. from every 25th of a second) but encoded as interlace.

  • Sorry in advance for my newbiest. I'm looking for a 1080/25p patch and I tested a few of it in HBR mode like LPowell Flowmotion or Quantum. When I insert one clip recorded in HBR in the StreamParser, the stream modeit is 1080/50i either in 24p25p-NINE as can I view in the screenprints.

    Adobe Premiere (for example) don't recognize the progressive mode, an says that is interlaced. Anyone can help me? Thks

  • From the short using 24p25p-NINE footage, 7-14mm on GH2. Can't post the film as in judging. Thanks again!

  • "Maybe I'll further improve this 9GOP setting at a later time"

    okay.... an update is in the works and will be released soon (25p already works fine) ...

  • @mickos

    cool! I am glad someone actually used the setting.

    I've stopped working on 24p25p-NINE as I couldn't solve the issue with PCR- and Clip-Duration. Also motion doesn't look that good... But for tableau-style work / static scenes it's great!

    Maybe I'll further improve this 9GOP setting at a later time.

    Here's another setting (just finished) for the very same purposes. It's good old Sanity V3.1 with the HQ Matrix and some other modifications applied.

  • Just used 24p25p on a 48hour film challenge needing 25p - it performed superbly! It was 7 minute one-shot genre - and only one scary "Recording cancelled" occurred - when the battery was almost flat. Fresh batteries and another 10 takes and no problems. Having 1h53m available on a 32Gb card was a bonus and the raw footage looked great (-2,-2,-2,-2 24p25p-NINE_HQMatrix_66M36M). Thanks Towi

  • "Did you test SH and H in PAL? Your settings from the day before did work fine" - strange ... they are exactly the same settings except of the GOP-setting for 1080i60. I've tested 720p50 in PAL mode. SH only, though.

    If you use PAL mode maybe just reload these settings (March, 3rd): http://www.personal-view.com/talks/discussion/comment/45642#Comment_45642

  • @towi Did you test SH and H in PAL? Your settings from the day before did work fine.

  • @Kihlian

    "How differs the Settings from 3rd March from this above? Tryed both only on 25p" - Re PAL modes it's the same. I've only changed the NTSC settings.

    "both spans" - cool! On my camera the settings don't span. But maybe it also depends on the birate that is actually allocated; maybe with scenes requiring lower bitrates the patch will span. Attached a new patch for spanning (tested at HBR, 25p only). It's the stock setting with only the following settings changed:

    • 30min limit removal=Checked

    • Video Bitrate 24H=44000000

    • Video Bitrate 24L=32000000

    • Video Bitrate FSH/SH=32000000

    • Video Bitrate FH/H=24000000

    • 1080i50 and 1080p24 GOP Size=12

    • 24p25p-NINE-Matrix included

    "I have a request since driftwood says that the 720p at 50p intra settings will span (but not 720p 60p) for us PAL users could be prepared a patch that include this settings for shoot slow motions?" - Maybe. As LPowell pointed out above, SH settings may also affect FSH (HBR) mode, so we have to try. I've tried to built in one of Driftwood GOP6 settings for 720p, but the camera crashed.


    @Tomaso

    "SH and H mode have every other P frame low" - I can't replicate this behaviour on my camera. Actually the 720p settings are copied from the Sanity patch. So I would think they should be okay.


    Today I recorded at 25p while driving on the highway. Clip duration is a little over 11 minutes. The stream looks healthy from the beginning to the very end (see attachment)

  • @towi New settings still looks good in PAL HBR, 24H, 24L, FSH and FH. But SH and H mode have every other P frame low.

    HBR around 50M

  • @towi How differs the Settings from 3rd March from this above? Tryed both only on 25p (it´s the only mode I use) both spans, works also on ex tele and give me an average of about 36500 Kps. Both also playback on camera. (On SanDisk HD Video class 10 30 Mbps. The funny thing is that with diftwood settings the camera remaining time shows about 26 min, and goes down slow, with yours shows about 55 min. and goes down faster. I like your settings. I have a request since driftwood says that the 720p at 50p intra settings will span (but not 720p 60p) for us PAL users could be prepared a patch that include this settings for shoot slow motions? (I´m completely ignorant of preparing settings).

  • damn :-)

    maybe NTSC users should better stick to the original Sanity patch (GOP18 for 1080i60 + FSH set to 44M).

    edit: attached a 24p25p-NINE version with Sanity-Style 1080i60 GOP size = 18 & 1080i50 GOP size = 9 (FSH bitrate set to 36M for reliable PAL/25p mode)

  • Similar result with GOP 12 for 1080i60 @towi

  • @aljimenez

    set 1080i60 to GOP12 and try again ...

  • @towi I have NTSC camera and I ran some tests with 720p60 - great; 24p - great, HBRp30 - failure in one attempt, then finally it looked like it worked filming leaves in large avocado tree in the wind, so almost like a death chart of details. Streamparser indicates some blips, see gone B-frames near frame 194.

  • "Of course, one needs to thank all others that contributed directly and indirectly: Ralph, Driftwood, lpowell, Vitaily, and the many who continue to share so selfishlessly"

    Very true!! Actually I did... but after editing my first post the acknowledgements are gone. Stupid.


    Attached 3 different film settings (smooth, cinema, natural) with 24p25p-NINE at ISO200 + ISO400 to check banding. All set to -2 | -2 | -1 | -2. Smooth at ISO400 looks okay. All other settings show heavy banding.

  • Thank you @towi for working so hard for this setting. I liked Ralph's SANITY since it first came out, and I am happy you have continued improving it. Of course, one needs to thank all others that contributed directly and indirectly: Ralph, Driftwood, lpowell, Vitaily, and the many who continue to share so selfishlessly... Al

  • UPDATE March 3rd

    So here is 24p25p-NINE with all modes enabled:

    • Video Bitrate 24H=66M

    • Video Bitrate 24L=44M

    • Video Bitrate FSH/SH=36M

    • Video Bitrate FH/H=32M

    • 1080 AQ4

    • 720 AQ3

    • 1080i50 and 1080p24 GOP Size=9

    • 1080i60 GOP Size=9

    • Sanity-Style 720p modes (720p50 GOP Size=30 / 720p60 GOP Size=39)

    • LPowell 100Mbps MJPEG

    NTSC mode has been tested on death charts only ... no real world tests as I only use PAL mode. Feel free to optimize the patch for NTSC (of course).

    HBR PAL mode has been tested extensively. In my book at HBR/25p 24p25p-NINE offers the best IQ of all the patches I have tested... both with static scenes as well as with motion.

    Actually I would consider this patch as Sanity MKII. So once again many thanks to @Ralph_B, the creator of Sanity. And once again a big thank you to @Driftwood who helped me to built in the matrix of 24p25p-NINE.
