  • @Shian Those were taken closer to the observatory.

  • @Tristan the pre-hack looks super clear to me. What am I missing? Why wouldn't we use the pre v. Sedna?

    @mozes What was the GOP of the transcode - 12/15 GOP?


    @driftwood i have no idea what you mean

  • To all GH2 and camera operators in the greater Los Angeles and SGV areas:

    This coming Sunday Michael and I are set to start shooting multi-cam comparisons of GH2 settings . I realized tonight that the more people that help, the more we can compare at the same time. Ideally, we might be able to shoot one setting per camera, allowing us to do more setups or test a greater variety of lighting conditions.

    To do this, we need as many duplicate lenses and bodies as possible, as well as operators, tripods and cards. If you can contribute either time or equipment this coming Sunday, please e-mail me.

    Shooting is currently looking to take place in one of 3 outdoor locations in Pasadena, Altadena or Griffith Park near Hollywood.

    Remember: the more help we get, the more testing results the site gets.

    @Driftwood If you think another week would make a difference in terms of having Canis Majoris or Cluster V2 available for the comparison, please let me know and I will try to re-schedule. I think the potential for debugging testing issues with several operators in place at the same time is appealing.

  • For the record, I'm Michael ;-) Looking forward to performing the tests.

  • @thepalalias How about Colorado or Lake, Morning light down through the high rises is usually very nice, east-side of the 210. Id help but Bay Area. The air quality there helps make the images warmer. I actually will alert a friend in LA of what you are doing.

  • @proaudio4 thanks for the comparison of the 3. sedna AQ1 seems to be the best! i just loaded it and will go test now. but already had issues - 720p gets blocked ,steady on tripod, almost right away on 16gb 95 mbits SanDisk(original)!which is slightly annoying. With Mysteron was able to use even 15mbits San Disks for 720p without much issues apart form panning on lots of leafy objects...i know its not recommended but it mysterion'sly worked...

  • @Luxis 720 50P or 720 60P?

  • @ExileNorth Probably won't be a morning shoot. Lately I get home from work around 3 or 4 in the morning.

  • @thepalalias 720 50P ...missing something?hm...and a little off topic but what is the improvement audio wise that you have worked on? for me the high noise floor is the real problem and i think this cannot be addressed since it is a limit of the preamp itself.

  • @luxis I will PM you about the hack (since it is off-topic) but suffice to say that the noisefloor was a catalyst for the work I did.

    720 50P (PAL) 720 60P (NTSC)

  • Mystic Settings... Have started to work with this patch...early morning hours, different lighting elements, metal halide, sodium vapor,incandescent etc. Shooting on the street various alley ways, businesses car lights and such. Appears stable in Premiere Pro CS5, as mts files, but as you work to render, encode or what ever, once you begin to see the results of render or encode you begin to see degradation, extreme noise in certain lighting, when attempting to remove or adjust for the noise then you lose focus, yes I understand lose of focus but... there is something in the patch that is reacting to the different light sources,color shifts....etc. My system is Alienware, built for just this type of work. I wonder if the matrix is being impaired? posting is crap or beyond garbage. Could someone express opinion on the color shifting idea? Thanks

  • @Exilenorth Did you mean Mysteron settings?

  • Mysteron footage from yesterday...

    A very quick, very sloppy edit -- slapped on the timeline in the order of capture. This was Vibrant at -2,-2,-1,-2. The ONLY thing I did to it was add mild sharpening to it in post -- to see how it would handle sharpening in post. As far as I can see -- it handled it.

    24H, ISO 160, daylight preset white balance.

    These are all wide shots -- accomplished with that 14-42 mm "kit lens." I really, really don't like that lens. According to various online evaluations the optimum settings are f/4 at the wide end and f/8 at the long end. All of these shots were wide, and all were in the range of f/4. Distortion is significant and in some images edge softness is outrageous. All that said -- it still works as a wide angle -- and if that lens is all you can afford -- you can succeed in making good stuff with it as long as you pay attention to what you're doing.

    This is all geographical "b roll" footage for various historical documentaries.

    As a side note -- at around 01:32 in that video I had to blur out my license plate because it was visible. I can tell you with confidence that there's no 1080 camcorder on the market today that would have clearly made out the characters on that plate at that distance. This is unique to this hacked (Driftwood high bitrate) GH2.

  • @OnionBrain I feel you on the 14-42mm. I only had to use it once to say "okay, next" .:)

    @ExileNorth Here is a comparison of how Mysteron and Sedna AQ1 A handled the same extreme contrast and gamma adjustment to emphasize noise.

  • @thepalalias @onionbrain, Just looking a onionbrains piece, looks good, available light situation but, {Comment=Mysteron SD_Card=Mystic Setting) the outcome is totally different. Odd, because when I look at the mts files the noise levels are acceptable, once messed with then the degrading begins. I will return to the location tomorrow as we will be having rain. I will shot with Orion and Mysteron, need to compare. otherwise all is well. I have been shooting at iso 1600 at a 60th. Lens 24mm @ 5.6

  • Nice wheels OnionBrain!

  • @ExileNorth I didn't quite understand the "{Comment=Mysteron SD_Card=Mystic Setting)" part of your comment. But best of luck with the test and remember - if you are testing during daylight, even a fairly small change in sunlight can make a big difference in the codec comparison. That is why so many of my comparisons are shot at night, using the available artificial light.

  • @alcomposer That's a twelve year old car with over two hundred thousand miles on it -- please don't be impressed. When I bought it -- nine years ago -- it impressed women. These days it only impresses old guys -- like me.

  • @onionbrain, reminds me of Virginia, in the Valley. or Stone Arabia, New York. Nice light on the old homesteads.

  • @exilenorth

    I'm didn't follow what you wrote either. Please be gentle on the guy with the vegetable for a brain -- me.

  • @exilenorth

    This comment I understood. And, you win a prize -- it's the Shenandoah Valley of Virginia. I'm in the middle of three Civil War historical documentary film productions -- and some of this stuff may be used.

  • @thepalalias i meant to say yes-it is 720 50p...did a little testing last hour and yes the leafy stuff blocks it big time,battery pullout...sometimes the ext mode too...but its very "selective"...also maybe high iso could some times block it. the 24p and 1080i works just fine.

  • @luxis That is odd about Sedna AQ1 and 720 50P. I found Sedna AQ1 C to be remarkably stable in 720 50P on a Delkin 16GB 95MB/s while shooting "Prayer of Light", even when average bitrates got over 90 mbps.

    Were you using Sedna AQ1 A, B or C? Did you try the usual bag of tricks (do a full format of the card on the computer, then format on the camera, etc.)? Was it a manual or AF lens?

    This is puzzling and leads me to believe I may need to do more extensive testing in that mode.

  • @onionbrain Absolutely stunning!
