    @CRFilms With new lith-ion batteries you should always charge them full up (even let sit for an extra short bit when 100% charged), then drain them to 0% ENTIRELY before recharging. Do that at least a handful of times, otherwise the battery may never operate at full capacity. Or so the tale goes.

    Consistent sensor temperature is a key part of the performance of the camera.

    Interesting.

    Did they made sensor temperature measurements of other cameras? I mean ones with just passive cooling.

  • johnbrawleyjohnbrawley

    Just the sensor.

    Consistent sensor temperature is a key part of the performance of the camera.

    JB.

    The point being that the sensor temperature is constant within the confines of how much heat can be radiated through the body if the camera.

    Do they cool sensor only or also their main FPGA chip?

    I also think that the lower sensor temperature - the better for image.

  • johnbrawleyjohnbrawley

    The point being that the sensor temperature is constant within the confines of how much heat can be radiated through the body if the camera. More power is used when the body is hotter due to either ambient temperature or the temperature of the "cooling" itself.

    Similar to what some use to keep overclocked CPUs cool it's a solid state refrigerator.

    It is not very accurate reference in such scale.

    In fact it is more similar to solid state heater (and refrigerator is also heater for outsider :-) ) :-)

    To be short - it cools one side, while heating other (adding their own heat :-) ). Most of the time because produced heat is more than original heat they are useless in overclocking.

    Reason to use such solution can be bad heat spreader or chip position, so overall temperature rise and you need additional cooling of specific area.

    Similar to what some use to keep overclocked CPUs cool it's a solid state refrigerator. Same as the Arri Alexa :-). There is no fan on the pocket.

    My understanding is the cameras use a Peltier cooler.

    @johnbrawley

    Active cooling system? What exactly does that mean? A fan? Something else?

  • MRfannyMRfanny

    i find battery drains the same regardless of shooting or not. I also noticed battery indicator isnt all that accurate when charging. If you want a real indication after charge, unplug, turn off, turn back on again and check. Not sure if that has been fixed in the recent firmware updates

    The original batteries last long, its the cheap ebay stuff that only lasts 30min or so if you are lucky

  • johnbrawleyjohnbrawley

    The camera has an active cooling system. The longer it's on, the hotter it gets, the more power it has to use to maintain the sensor temperature.

    This is why battery consumption varies wildly. Hotter conditions, more stuff on the camera with rigs that affect heat dissipation and long continuous operating will all cause increased power consumption to keep the camera cool.

    My $895 Black Friday Pocket Cam special just arrived. I did a quick test, in Prores with a full stock battery, a 64gb Sandisk Extreme Pro recorded 46min and the battery read around 35% left. Not too shabby considering what some have said. Though, I then charged it back up for about 20 min and the battery read full. I just left it on for 5 min with the charger unplugged and the battery dropped to 90%. Feels like it runs out of juice faster when it's just on vs on and recording. Weird.

    Sorry ...I don't speak English

    There is ''horrible noise'' in my video...on the leaf

    I use lightroom...convert in tiff 16...vegas export

  • vicharrisvicharris

    Or you shot it in Video mode. That doesn't look like anything filmed in FILM mode I've ever seen come out of the camera.

  • jrdjrd

    @kurt10

    You say "no color correction", so it would appear you didn't process the RAW footage. The procedure for handling RAW in Resolve is described earlier in the thread. Go back and read it.

    RAW footage may or may not look acceptable out of the camera, but it's not designed to be used without first processing it. If you want the most flexibility in color grading, you need to convert the RAW shots into BMD film log. Then begin the color correction process.

    If you want the footage to look acceptable directly from the camera, shoot Prores with the "video" setting.

    i have a problem with the bmpcc

    What is it??? :x

    no color correction..

    It's sharp at t4 and beyond. If you don't believe me I have some footage of it from the 2.5K and that'll pretty much end this conversation.

  • peaceonearthpeaceonearth

    I own that lens too but up to now never used with my BMPCC. I know by personal experience what this camera can display therefore my question about sharpness of the 12mm SLR magic

  • vicharrisvicharris

    @JuMo

    Well said. I somehow liked it where it was though like always, the original on my 27" LPS monitor looks just fine :)

  • JuMoJuMo

    To be absolutely clear to the never ending stream of 'soft video' commentors: this camera can go sharper than you'll realistically ever need (in RAW). Lens softness and glow aside, you have control of how sharp you want the footage to be in post, so when something isn't sharp enough to your taste, it's because either a soft lens was used or the footage is sharpened to the taste of the person who posted it. That said, ProRes is definitely a little softer and doesn't sharpen quite as well, but is still very flexible. RAW can go so sharp it will make you cringe.

  • vicharrisvicharris

    @nomad There's some there but they way I usually have used this lens in the past it was never a real concern for me.

    @peaceonearth I've always been satisfied with this lens and the original one paid for itself many times over on shoots. Of course when it got darker, I had to open the lens up to t2 and it's been pretty known for some time that you need to stop this lens down a little to sharpen it up, things start getting better by 2.8 then by 4 your good but I valued the changing colors of the sky at that point over sharpness and was afraid to switch to 1600 asa on the pocket. I'd rather deal with some softness that grain city. I probably could have sharpened up the footage some more as the pocket shoots soft anyways but liked it where it was.

    Also if you see the shots where there's plenty of light at the begging, it rocks and I've always loved this lens for it's flares. That's the main reason it will always be close at hand.

    If you check out this promo I did awhile back I used the 12mm about 80% of the time or more and the clients loved it :)
