    Improve your pocket 4k videos!

    In: Cameras

    Posted

    Hi Guys,

    Yes, you are right. I am the developer of the Cinema 4K app.

    I have started this development, because of the limitations of the built in camera app. I have also tried other apps for 4K video recording, but at the end I decided to write my own.

    I have tested it on an LG G4 and Samsung Galaxy S6. On LG G4 the AE lock is not working and  - because of the weaker CPU - the 4K recording sometimes drops frames when other apps are running in the background. On the Galaxy S6 there is no SD card option, however I could attach an external storage over OTA and configure the app to record there. Works good.

    Cinema 4K relies on the Camera2 API. This is quite new in Android and unfortunately not too many manufacturers implemented it on their phones. It also requires Lollipop (5.0) Android version. The Google Play Store automatically selects the available devices for download the app based on the OS. This might be the reason Note 3 is not listed. I will try to set this manually if possible.

    Thanks for starting this forum and your valuable feedback. I am planning to add some new features in the future, but at the same same time I would like to keep the app as simple as possible and not to overload. The main idea is to get the maximum quality from the camera and later on you can edit it on PC/Mac environment.

    Thanks and Best Regards,
    Gabor

    That sucks about the Android 5.0 requirement, was gonna test it on the samsung NX Android camera, might have been a new dark horse !

    I'll try to shoot some interesting stuff too. Im almost done testing its features.

    Im getting the best results exposing for the highlights and then bringing back shadow information.

    Does it have a stream to youtube feature like some camera apps ?

    That would be awesome !

    The Arm Cortex A72 SoC architecture which will be used by Samsung and other phone manufactures to make their chips, will have hardware support for higher 4K video bit rate and will do 120 Fps.

     

    so if you are getting a cellphone next year, make sure it's Soc is based on the Cortex A72 architecture. 

    Canon's new Blue Spectrum Refractive Optics Technology

    CANON DEVELOPS NEW CAMERA-LENS OPTICAL ELEMENT THAT ENABLES EXTREMELY HIGH LEVELS OF CHROMATIC ABERRATION CORRECTION

    The new Canon-developed BR optical element offers characteristics that significantly refract blue light, which lies within the short-wavelength range, to achieve impressive levels of chromatic aberration correction for outstanding imaging performance.

    Natural light, or white light, comprises a spectrum of wavelengths, or colors, each of which realizes a unique refractive index when passing through a lens. As all colors do not converge on the same point, this disparity causes chromatic aberrations, or color fringing, to occur in an image.

    The encoding I tested was HEVC -> ProRes 422HQ

    In the program I had to select ProRes 4k in order to be able to apply the LUT, I tested it both with 1080p100 and 2160p25 and it applied the LUT fine, some of my older 1080p25 overcranked footage before the increasing bitrate firmware came I see extreme banding in the sky but that might also just be me tweaking the settings to give me a flat profile with this ¤/!%#@( 8bit codec.

    The 1080p100 footage wont convert in ProRes 4k mode, I assumed its because ProRes does not support 100 fps or the program is simply incapable of it, though it will slow the footage down for you.

    DNxHD does not have the LUT option available its greyed out for some reasons, MXF is useless it gets wrapper problems, the MPEG Intra are 8bit only also useless, the TIFF 48bit mode worked fine for me as well with the LUT so did H264 export. 

    As for 25fps render for a 25p project file which was for ProRes, my computer is quite beefy so it tends to spit out 10 minute HEVC files in RockyMountains Converter in 2 minutes to ProRes

    10 minutes HEVC clip to ProRes in 2 minutes ? Computer specs please

    I'd either get the skylake i7 6700K cpu with h.265 hardware encoding support, or i7 5820K 6 cores haswell E processor for the best bang to performance.

    Get 2 SSD drives (makes a huge difference) Samsung 850 pro and evo, also cheap 2 TB 7200 RPM HD for storage.

    16GB ram or more is good

    Open CL is bringing faster results with some people, as of now it is getting more support and I'd look into the Radeon R9 390x, or if you require Nvidia skip the latest generation, it doesn't seem to bring any faster encoding and it is still not supported natively by many NLE programs, so research it!

    Get at least a 750 Watts PSU 80+ Silver, power is neglected by many and causes problems especially with power hungry GPUs while encoding !

     

    If you have a microcenter near you, they usually have bundle deals on the CPU + motherboard.

     

    Check Slickdeals for the cheapest prices on SSDs and GPUs

     

    also research pcpartpicker

     

     

     

     

     

     

    Canon's new $30,000 video camera does only 1080p

    In: Cameras

    Actually it says that it Pushes ISO to 4 Million. Which is technically 10 yimws that of the A7S. How much of that is really usable is what will be the deciding factor. And what other tricks it can do Apart from the 4million ISO

    Will the sensor is only 2 mp resulting in bigger pixels/photosites , while the A7S is 12 mp, so if Sony were to make the A7sII 8 MP for 4K capability with BSI and other enhancements it can probably reach above 1 million + ISO.

    And without real world results and how much noise it generates, how much DR it retains, etc.. we can not tell.

    The ME20F-SH is a low light capable video camera with photosites sized to 19 microns on it's 2.26 MP full-frame 35mm CMOS sensor to deliver an ISO equivalent of more than 4 million. The suggested retail price is $30,000

     

    I guess the A7s just got a little competition lol, will see how the cheaper A7sII will stack up in the Iso capabilities and real world low light performance.

    NX1 H.265 (HEVC) editing without transcoding

    In: Cameras

    Posted

    Looks like Google might save the day with the free VP9 alternative to H.265.

    This post recommends holding off choosing new hardware based on either for now: http://www.streamingmedia.com/Articles/Editorial/Featured-Articles/Is-it-Time-Yet-for-4K-H.265-and-VP9-Adoption-Not-So-Fast-104430.aspx

    It does look like lots of new Smart TVs are able to use both. If they are as good as each other and one is free, surely that will win though?

     

    skylake supports VP9 Encode/Decode

     

    And btw it seems like the native H.265 hardware decoding/encoding in skylake is limited to 8 Bits for 4k, and you'll have to wait for intel's 7th gen in 2016/2017 canon lake for native 10 bit 4k hardware decoding / encoding 

     

    This doesn't mean that a software solution won't be possible, but will be slower and the quality might suffer without native hardware acceleration.

    The kick starter page mention android BT connectivity & phone app with streaming, but will I be able to use it as a phone camera to stream live events on youtube or only their own streaming platform?

    Posted

    Adorama is having a special bundle of the G7 with the G Vario 14-140mm power OIS lens plus free Audio-Technica AT8024 Stereo/Mono Camera-Mount Microphone for $1098, but they are also offering an extra $200 off any other lens bought with the bundle, so which of the following lenses offers something extra or better IQ or usefulness for video ?

    Panasonic H-H014A Lumix G 14mm, f/2.5 II Aspherical Lens for Micro Four Thirds

    Panasonic LUMIX G Vario 45-150mm f/4.0-5.6 ASPH Lens, Black

    Resolve 12 Will Change Everything

    In: Cameras

    ​I did not look into this too deeply. Just out of curiosity, I tried (with FS7 XAVC footage, transcoded to ProRes and BMPC 4k Raw) with Resolve 11 Lite:

    The timeline settings allow "4k UHD", which is then fixed to 3840 x 2160, not changeable in Custom. The footage (4096 x 2160) can be imported and plays. 

    But if you do the maths, UHD is 16:9 (3840 divided by 2160 is 1,77) and 4k equals 1,89, a different aspect ratio.

    This is confusing, because cinema 4k (1:1,85 or 17:9) would be 4096 x  2216.

    How is that scaled then? Don't know right now.

    ​They must have limited it to UHD-1 which is used by Youtube, it should be 1.78:1 aspect ratio with 3840 x 2160 pixels at 16:9

    Cinema 4K or DCI 4K is 4096 x 2160 pixels with 1.9:1 aspect ratio, and I guess we will need the full version for DCI.

    The 3D support had me confused, so the light version does support 3D Luts but not Stereoscopic 3D, sweet.

     

    But it still does not fully support 4K :

    What is their UHD limit, 2K ? or the FPS ? or time ?
