@Reshaydee

it depends on wether or not you need spanning. cbrandin's 44M/32M AQ4 or Ralph_B's Sanity in the respective low modes will span. At least on SanDisk cards (30MB/s). Sanity provides higher IQ... IMO.

Other than that I shoot in PAL mode ... so I can't comment on HBR/30p and/or 1080i60.

I guess for your needs Sanity should be very good (for event capturing). For your music video project personally I would use GOP3ZILLA.

If i wanted a setting/hack for use on a music video using a extreme pro 90MB/s in 1080 Pal 24p, which one would be best suited? im confused with all the different hacks.

Any advise would be much appreciated

Thanks Dtr

I want a flat looking image so i can colour correct it to my taste after in post FCP, i want to get high quality+performance because i cannot afford to have stability issues while on location. high bitrate and balanced performance is a must, I will have to keep researching hacks to find the best for what i need...

I'm playing with sedna presets, I see there are more than one , A B C D E H, some of them crash my gh2, (I have a Trashend SDHC class10 32GB). If I just lower the bitrate from the crashing preset, can that be a solution ? Thanks

Moved this here per VK's request.

I would like to try use my GH2 for particle image velocimetry and was wondering if any patches discussed here would have significant advantages over stock 720p 60 fps mode

PIV is a technique whereby fluid motion is measured by illuminating a plane with a laser light sheet and measuring the motion of particles illuminated in the plane from one frame to the next via frame to frame correlation processing on subregions of pixels (for example 16 by 16 or 32 by 32 ).

http://en.wikipedia.org/wiki/Particle_image_velocimetry

I need to use the 720p 60 fps mode as the 30 fps modes will allow too much motion between frames. The processing will be done on a frame by frame basis so the least interpolation possible in the video compression is desirable. Stability is also important as the clips will need to be ~ 15 minutes long to achieve adequate statistics of flow properties

Do any of the knowledgeable people here have any reccomendations on settings or a patch that I should try for this. Thanks for any feedback,

Do any of the settings modify or improve the HD mode? (ie 720p/30 motion JPEG)

As a rough analogy, is HD MJPEG mode somewhat like an AVCHD all-I mode meaning it's full detail frames every frame and not doing compression based on differences compared to surrounding frames?

@DeShonDixon: The HD MJPEG mode looked surprisingly good to me with Mysterion settings, and the settings definitely modified this mode, as the output was 1080p, not 720p.

Hi all,

First of all, great work everyone on the patches.

I'm looking for a patch (or multiple patches) to be used on a feature-length documentary.

We don't care about wasting lots of hard drive space or buying 64GB SanDisk 95MB/s cards or whatever. We want the best image quality possible in each of these situations.

One patch for talking head interviews. (Spanning especially important here) One patch for run and gun footage, some it fast motion. (Playback is important here) One patch for establishing beauty shots. One patch for available low-light work.

Your help is greatly appreciated. Thank You

Dan

@robbie75vr, if you want to run the highest bit rate settings, I would go with the highest quality card you can get. I see a lot of recommendations for the Sandisk 64 GB in these forums.

I don't think altering the Sedna settings to lower the bit rate will be the easy route. For one thing, the authors tune everything to be at it's best as configured, if you just drop the bit rate it'll probably have really bad results. Instead, if your card can't handle Sedna, try one of the other great settings that isn't quite as demanding: Cake, GOP3Zilla, Sanity 5, or No Adverse Effects.

Sounds like a good plan. I've been REALLY impressed with some of the "middle of the road" bit rate hacks which are still way higher than many of the other cameras out there. Stuff between 44Mbps and 65 Mbps (IIRC) is giving me amazing video. I'm sure there is some extra little quality that can be eeked out, an someday I might need it, but for now I'm really happy with the quality and it's stable which is worth quite a bit too.

I don't know the exact difference between AQ1 and Q20 but from reading other posts here it has something to do with the quantization tables or parameters I think. AQ might mean auto quantization and Q20 might mean selecting a different kind of quantization. Some are expected to handle situations better than others, but the highest settings can also fall back into a low quality mode if it over taxes the processor on the camera so choosing the highest setting isn't always the right solution. I may have a few things crossed up but I think that's the basic idea. We can leave that to the settings authors for now and just trust they are tuning things for the best performance and aiming for stability with high quality cards.

One benefit of the moderate bit rate hacks that still have great quality is longer record times and burning up less of your hard drive space.

I have yet to see any of the Quantum series Driftwood Intra settings going into fallback mode. Indeed, if you shoot with Sedna Q20 during the night on a lit subject like a face, the bitrate required will drop accordingly to around 60Mbps for example - but take my word this is still top quality. As soon as the detail creeps up more bitrate is consumed. Whereas AQ1 will push the bitrate to a more constant level. :-)
