Why bother with P and B frames? If all the frames are the same size you'll get better results with just I frames.

@eyefi

Does "Pasadena Pulse V2" add overall bitrate? If so, I'm not sure the settings will span ...

cool - thanks! :-)

@cbrandin 12:28AM @mozes Why bother with P and B frames? If all the frames are the same size you'll get better results with just I frames.

you are right, but it is more stable...

I am testing gop 1 now...

@towi

Since I had combined SednaAQ1C with GOLGOP3-13 for my friends, I am not looking at your new setting in detail. However, looks nice for me! :-) Although I am busy now, I touch NTSC, if time is made.

@ someone who loves "Sedna" :-)

I release "GOLGOP3-13_SednaAQ1C" setting.

Of course, this is also the setting focused on image quality with LARGE I-FRAME SIZE except 60p and 50p.

And, I am also focusing to stability.

Please refer to here to combine @thepalalias's "Pasadena_Pulse_Audio_V2_Beta2" http://perlichtman.com/pasdenapulse/wordpress/2012/03/14/panasonic-gh2-audio-settings-file-pasadena-pulse-audio-v2-beta-2/

Please try it.

Special thanks to @driftwood! :-)

SednaAQ1A Version: http://www.personal-view.com/talks/discussion/comment/53563#Comment_53563

NOTE:

*It has not fully been verified yet.

*Although bit rate setups are quite high, the bit rate which actually appears are lower than these. Since the actual bit rate changes by the object to shoot, please confirm by yourself.

*24H mode is high quality 3GOP setting with mega size I-frame.

*24L mode is for 24p80%(30p).

*In camera playback is available in 24p. In other mode, Sometimes available.(Not tested yet, but probably)

*EX Tele works.(Not tested yet, but probably)

*Spanning in 24H, 24L, maybe in FSH, HBR, and SH with SanDisk 95MB/s 64GB SDXC Card.(Not tested yet, but probably)

Re: GOLGOP3-13_SednaAQ1C/HBR30P...and a bit off topic.

Question: Regarding HBR30p wrapped as 60i. I have noticed that regardless of the hack or native GH2 FW HBR30p always seems softer than Cinema 24P. Yesterday I was testing out GOLGOP3-13_SednaAQ1C in 24P and HBR30P (see screen grabs) and noticed subtle 'interlace' artifacts (look carefully at the 'grass' which was blowing in the breeze). I viewed the clip in MPC-HC and WMP the artifacts persisted. I then 'deinterlaced' it via TMPGEnc 4.0 and output it as an HQ 'Bluray' file. It almost doubled in size however it no longer displayed interlace artifacts. I just re-shot the clips for these screen grabs and StreamParser analysis and note that 24P is a bit larger than 2x the size on the HBR30P clip. Hmmmm..what's going on here...

So my question is: Does anyone recommend a player that can display a 'native' HBR30P file as noninterlaced?

@towi Took you Span50HQ1_1 v1_1 out for a spin on my dashboard when running an errand this am. Used Sedna B on my second camera to compare to Sedna B intra. I've attached the charts for span50. Is the 2nd chart what you expect? I may not know how to read stream parser correctly, but checking some of my other gop3 files, I don't see as much difference between time frames. Although I haven't had a chance to really shoot much, so far looks pretty good. I'll not make any definitive statement till I get some more time and samples to look at. Hoping I can shoot a little more today. Thanks for your efforts.

please do NOT use these settings

@Bonzai

Thanks always! :-)

"interlace artifacts"

I also sometimes look at it with various settings. I do not know whether this is peculiar to HBR, or whether it is the result of GOP3 or something.

@towi

How do you think?

bkmcwd The HBR30p interlace issue doesn't appear to be specific to any particular patch - in fact I can duplicate it with the stock GH2 V1.1 firmware.

I've always thought that something wasn't quite right with HBR30p. A few weeks back I noted very subtle interlace artifacts in a clip containing video of a section of very narrow side trim on an automobile. This occured while panning but no evidence of it when holding the camera still.

The example I posted with GOLGOP3-13_SednaAQ1C-HBR30P also makes them visible but again not easy to see when holding steady - in this case the narrow leaves were being blown in the breeze demonstrates the artifacts. None what soever with Cinema 24p.

I performed that test with GOLGOP3-13_SednaAQ1C, Mysterion and stock V1.1 (after formatting the card, rolling back to 1.0 and updating to V1.1) and the 'interlace' artifacts persisted. It is very subtle - it takes a trained eye to identify the issue. Nonetheless I believe this contributes to the soft look of HBR30p. I can re-encode the 60i wrapped file as 30p and all is well although the file size almost doubles.

Bottom-line: I would like to find a consumer video player that will play back a native HBR30p as 30p and not 60i.

I'm in NTSC land like yourself. The 30p output provided in V1.1 was a huge gift to me as it is far smoother with the occasional pan than Cinema 24p. It also makes file handling simpler in NTSC land than 24p. I'm trying to figure out what may be causing the HBR30p files to display as interlaced in common video players. I do a lot of splicing and transitions along with 'stills' derived from screen captures but rarely perform any real 'post' processing. I would like to keep it that way.

I DL'ed the ..hbr30p_night_sample...M2T original file from Vimeo and looked at the 'pink bow' rather closely (see screen grab crop #1). Then re-encoded it as a progressive 29.97 Bluray .mpg via TMPGEnc V4 and cropped the pink bow again (see screen grab crop #2). #1 looks interlaced while #2 appears progressive. Anyone have any ideas what might be going on here?

@towi "but in my book bkmcwd's patches work MUCH better in HBR mode (likewise in FSH mode) without any custom matrix applied. Things look different at 24H"

But not different enough for me, currently I don't think using a custom matrix on GOLGOP3 gives any real benefit over ther stock matrix (even in 24H). As @bkmcwd says maybe a matrix specific to GOP3 would give more improvements. As it goes I'm using GOLGOP3-13_V4.12 as my default setting, I'm more than happy with it. I did try the new version with Sedna A yesterday but I didn't see any real benefit to it. I should probably test it under more different conditions though. B frames are definitely fatter with that matrix, but it doesn't seem to be visibly beneficial. When I Initially tested it with the first version with the matrix I got the impression that the overall rendition was better than the stock matrix with GOLGOP, but now I've had the time to really push footage around I'm not convinced. But I will do more tests on the Sedna A version. @bkmcwd How do you feel the Sedna C version looks ?
