  • SOME BATTERY MEASUREMENTS - running the Black using USB power, with battery idling...

    Through the GoPro supplied USB cable (0.27 ohms), a 5V supply does not provide enough power to fully supply the camera. A little will still be drawn from the camera battery. Here are my measurements of voltage and current drain at 1080M 24T (with Touch LCD) from my variable bench power supply:

    4.90V = 340ma used

    5.00V = 410ma

    5.10V = 500ma

    5.25V = 630ma (670 when filming)

    6.00V = 560ma

    So the camera needs a 5.25V input voltage if you are to avoid draining the internal battery. Above that voltage the switching supply inside the camera works fine (as you can see from the 6V reading).

    The reason I noticed this is that I built a DIY adapter to run the Black from a GH2 / FZ200 battery, and I noticed that there was still some drain from the camera's battery. When the voltage of the adapter is tweaked to 5.30V the internal battery maintains its charge OK, and from a GH2 battery you get about 2 hours of 1080 Protune filming (with the Touch LCD attached) before the internal camera battery has to kick in. The Touch LCD drains about 150ma.

    IMO this is a Hardware limitation, not a software issue. The camera was in 1080M 24T. At 2.7K 24T the camera drain rises to 750ma (incl LCD). WiFi is an additional 45ma.

  • Does anybody know what the newest firmware adds to the camera other than smartphone compatibility? I have noticed that now 720/120 has the option of wide & narrow (narrow being the update) is there a list somewhere?

    no playback capability through smart device, unless I am missing something.

  • @5thwall That's for photos. It's more of a PITA to correct video inside Photoshop. After Effects is way more powerful, even if rendering takes a bit.

  • @BlueBomberTurbo how do you open up the video clips with camera raw? is it quicker to render than using after effects and optic compensation?

  • Rendering my first 3D test right now, synced with PluralEyes. The new firmware kind of killed the sync that the old one had. They don't beep or start in unison anymore.

    Also learned that you need to stand at least 4ft away from things, or the things in the foreground will mess you up. This is with about 3" spacing of the cameras.


    BTW, for anyone who wants to remove distortion from photos, Adobe Camera Raw does it perfectly with these settings:

    Lens Corrections > Profile Setup: Custom Make: Sigma Model: Sigma DC 4.5mm f/2.8 HSM Profile: Adobe (Sigma DC 4.5mm f/2.8 HSM) Distortion: 200

    Lens Corrections > Manual Distortion: +100

    Then you just need to correct the Vertical to whatever you like, crop the image, and it's perfectly defished! This is done in the most current version of Camera Raw, 7.3, but you can do it in any version as long as that lens profile is available.

  • @Hallvalla I can play back 2.7K on the Touch LCD. With audio. It is OK for a quick check everything was recorded OK :) Haven't tried 2.7K into HDMI monitor yet.

    (3 quick taps on the Touch LCD take it into playback and back to shooting. That's my empirical method - there may be a better way of switching)

  • I can't figure out how to do playback on iPhone after the updates. Anyone successful?

  • @Hallvalla Honestly, not sure, but I've read that people have been able to play back vids at anything but the two super high res settings.

  • @BlueBomberTurbo So if I shoot something at 1080p 60fps, I can view it on the phone app? I'm talking about the recorded footage.

  • @5thwall Awesome test! Your weather looks similar to mine. ;) I'll be setting up my steadicam and monopod for tomorrow at the track. And yeah, I love the look with the distortion corrected. I do it to all my GoPro vids since I learned about Optics Compensation, and the Black corrects even better than the GP2. It does get a bit blurry on the sides from all the stretching, though.

    @Hallvalla Right now, only in the standard HD formats. 2.7K and 4K are not viewable, just like on the LCD Touch Bacpac or through HDMI.

  • Hi - does the new app/firmware allow to view recorded footage?

  • Hey y'all. Lucked out and got one at Best Buy last week. Been doing some tests to see if I can use it as a b-cam on some newsy, docu, corporate pieces. Here is a very rough test using a Steadicam Smoothee and Lock and Load for image stabilization. Also used After Effects Optics Compensation for fisheye removal. It does a much better job than any of the other plugins I tried. Shot in Protune, 2.7k, at 23.98.

  • Haven't tried anything yet because of the weather. I won't be doing long shoots, anyway. I hear the drift isn't significant on clips of a minute or two (at least with the GP2).

  • I was thinking about your 3D setup last night, and particularly how the loss of frame sync between the cameras might interfere with the brain's position locating during inter-frame motion blur. How have you found this working out for you?

  • @trevmar Haven't gotten a chance to do anything besides update the firmware before I left for work. I'll be playing around with everything at lunch and after work. Need to get some 3D test footage, too, but the stupid weather in the "Sunshine State" has been cloudy/rainy for well over a month now... -_-

  • I did a manual update as I don't have Java on my browser - it is a security risk :) Thanks for the info, though. Seems I did it the hard way (tried to use the Cineform Studio software to recognize the camera). Have you gotten a preview on 2K7 or 4K yet?

  • @trevmar When I installed the firmware on both my cameras, the site asked me to enter a Wifi name and password for each. Did you download via the site or manual update?

  • I downloaded the new Hero3 firmware, still the same version number, but different file sizes. Installed them on the camera. Installed the android app (as of 7:30am PST). the Cineform studio version is still 69, which doesn't recognize Hero3. So I figured out the default WiFi password was "goprohero" and connected the app to the Hero3. The preview lags about 3-5 seconds, and is the same size as my Touch LCD (which has no lag). The app will not show 2K7 or 4K previews at all, and the setup screen is clearly not yet compatible with the Hero3. But at least the app "record" button works OK, as does Power on/off. Still, I can do that with my remote LOLOL.

    I guess the next step is waiting for the android app update. But all-in-all I am under-awed at this point :)

  • My app updated last night around midnight. Now I just need a Hero3 to go with it! :)

  • Yup, it's out. New firmware 1.1.13, but doesn't seem like the app has/needs an update.

  • Does anyone know if the update has been posted that enables the GP3 Black Edition to connect to the app? I haven't seen it, yet.

  • @stonebat Yup! Made from a couple of macro sliders and misc hardware. :3 Stripped the rubber grip from the bottom one, so the GPs can parallel align to the left over groove. Found that just tossing 2 on one slider with the tripod mounts was a headache, so I ditched the cases completely. Hopefully GoPro improved their tolerances for lens mounting on the new cams.

    There's also enough room for all power and video cables on both, and can push the cams out to the sides for shooting distant objects. If I can figure out how to make the right kind of mounts, I can also set them up like the original 3D housing, too, though that's not on my list of priorities. At the moment, the they're a little further than intraocular distance, but that's fine for now.

    Testing for the next 2 days, since the weather's finally clearing up around here. If all goes well, I'll be shooting a drifting event on Sat! :)

  • DIY 3d case?

  • Wish me luck!

  • This week is still good. It's amazing that people have been using GoPro units without preview feature.
