Lift-Up Posted August 25, 2015 Share Posted August 25, 2015 Hello! We cant carry our NX1s, GH4s and A7s with us all the time. For those who want a good 4k camera that you can carry all the time, thats the best solution that I have found.The best Android phones shoot 4k with a bitrate of aprox 48Mbps. They are not bad, but they have too much compression artifacts, contrast, saturation etc.A few days ago I found an amazing app, and I would like to share it with everyone. I have no bonds with the app developer, but im afraid he will give up his project if there is not enough support. Im pretty sure he can make things even better.What we have now with the app is: - Flat picture profile (It recovers a good amount of highlights and a little bit of shadows)- Better noise reduction (more like film grain. The stock one is very blocky)- 24 fps - 30 fps- 200Mbps!!! Thats the best part! Much better video quality. Less macro blocking, less banding etc, so you can recover more detail, grade the videos with the less problems etc. Frame grab from the Samsung Galaxy S6 stock camera - 4k at 50Mbps Frame grab from the Samsung Galaxy S6 using the app at 200 Mbps There is a lot of room for improvements, like more manual control, more control over the picture profile etc. But I do think that, at the moment, thats the best 4k camera that you can carry around all the time! Lets support the guy, so he can make it even better! The name of the app is CINEMA 4K, and its available for free at the play store! Make sure to update your phone to 5.1.1!!!

Lift-Up Posted August 25, 2015 Author Share Posted August 25, 2015 MUCH LESS compression artifacts. At 200Mbps you eliminate a good part of the nasty macro blocks. There is basically fine noise, wich is not bad at 4k. Quote Link to comment Share on other sites More sharing options...
Cinegain Posted August 25, 2015 Share Posted August 25, 2015 Hum, interesting. Thanks for the share.I will try to see if this works with my Nubia Z9. I'm afraid that it will and consequently make me want to shoot a project with just my phone. Quote Link to comment Share on other sites More sharing options...

I think this is STELLAR. The colors have become more natural, and the shadows have been lifted pretty well too. I was unable to find an app called "CINEMA 4K" in the Android store. But, the screenshots you have posted are pretty amazing. I am guessing that this could easily be used for a feature, and could be graded pretty well too.

Antonis Posted August 26, 2015 Share Posted August 26, 2015 I tried it on my Sony Xperia Z3 compact. Sadly the app didn't work on my device.According to the developer, Sony doesn't support or give access to the camera API. Quote Link to comment Share on other sites More sharing options...

Lift-Up Posted August 27, 2015 Author Share Posted August 27, 2015 Sorry to hear that! I wonder if its only optimized for the Galaxy S6 or maybe only to the latest flagships, like the LG G4 and the OnePlus2. Anyway, here is a Dynamic Range comparison between my old Galaxy Note 3 using the stock camera at 50Mbps, my sisters Sony AX100 at 100Mbps and the Galaxy S6 using this app.I had to edit the video via youtube so the resolution was decreased to 1080p. What I saw: Galaxy Note 3- Decent video for a cellphone- Image looks cheap. Too much saturation, contrast, cheap colors- Bad dynamic range, mainly due to the picture profile- Too much sharpening. Ugly haloes on fine detail. Digital look- Too much artifacts. Bending on saturated areas and too much macro blocking on dark areas Sony AX100- Nice detail- Handles artifacts well. Clean image. A little bit of bending- HORRIBLE white ballance. Every single image has a purple casting. (At least in auto mode)- There is too much noise reduction for my taste. There is no texture on the image. When you zoom in, it looks like plastic.- The dynamic range of the camera is not bad, but in auto mode, it tends to blow out 5-10% of the image all the time Galaxy S6 modded- Great level of detal. MUCH more than the stock camera. On par with dedicated cameras.- No artificial sharpening. The detail is there, but there are no haloes. The image looks very organic, but not as soft as a canon XC10. Its better ballanced than most dedicated cameras that I have tested.- The dynamic range is improved by a lot. The scene has a lot of contrast and the result is pretty pleasing.- There is only a little bit of noise reduction. You can see some really fine noise all over the image. It doesnt look like nasty noise. It looks a lot like fine film grain, and I love it. It increases the details, textures, and make the image look less digital.- The colors look more natural. Good auto white ballance. Quote Link to comment Share on other sites More sharing options...
Lift-Up Posted August 27, 2015 Author Share Posted August 27, 2015 GRADING STRESS TEST IN 4K The objective here was not to get a pretty look, but to push the codec. - The highlights were brought 80% down to search for banding, specially in the blue sky.- The shadows were pushed up to 40% to seach for macro blocking.- 5% of vibrance- Contrast at negative 5% (good to show limitations of 8-bit videos. It shows lack of gradation)- Unsharp mask at 1.5Conclusion: It holds up pretty well! For those looking for a filmic look, you will be able to intercut your phone with your main camera easily! Special points for the color reproduction. Pretty spot on! vaga 1 Quote Link to comment Share on other sites More sharing options...
benymypony Posted August 27, 2015 Share Posted August 27, 2015 The last commercial video for the new perfume "TOTEM" by KENZO has been partially shot with an iPhone 5.Check at 1:15 : https://www.youtube.com/watch?v=ugCj2JD8xp4 Quote Link to comment Share on other sites More sharing options...
Lift-Up Posted August 27, 2015 Author Share Posted August 27, 2015 For those interested on differences between bitrates.Not only for this camera, but for pretty much every other one, thats whats hidden on your footage. Sometimes you cant see those blocks clearly, but they are there, ruining your images in the shadows, saturated areas, highly detailed shots (like shooting leaves and grass) and when you are panning. 50Mbps (200% zoom)100Mbps (200% zoom)200Mbps (200% zoom) More bitrates transforms those compression artifacts into detail and fine noise. 50Mbps (400% zoom)100Mbps (400% zoom)200Mbps (400% zoom) Cinegain, kaylee, Mat Mayer and 1 other 4 Quote Link to comment Share on other sites More sharing options...
Cinegain Posted August 27, 2015 Share Posted August 27, 2015 The app said some things might not be working properly with my phone, but it seemed to work just okay. The focus assist is a pretty cool feature.Will give it a spin in the afternoon tomorrow, see if I get similar results. Still not sure about intercutting with other footage and if it looks 'filmic'. But it seems great quality for standalone projects and bits. Quote Link to comment Share on other sites More sharing options...
LimitBreak Posted August 27, 2015 Share Posted August 27, 2015 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.

Lift-Up Posted August 27, 2015 Author Share Posted August 27, 2015 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.I have tested another app. Its called Cinema FV-5. Its also nice, but Cinema 4k gives me much better results.------------------------------------------------------------------------------Now the colour test Zooming at both videos the difference is pretty clear. Although both videos are 8-bit, the 50Mbps looks more like it. The tiny amount of data for 4k content introduces banding, blocking and bleeding, creating an image with poor gradations on luminance levels and color tones/hues/shades etc..

Lift-Up Posted August 27, 2015 Author Share Posted August 27, 2015 Nope, and it probably wont have that.That app is aimed at camera enthusiasts. For those who want the best possible image quality, grading possibilites etc.There is no point on shooting at high bitrates for a low bitrate streaming. There are lots of good apps for streaming to youtube though. Video apps with real time HDR video should give you great results.------------------------------------ BTW. Android users that have updated their phones to the latest 5.1.1 firmware can now shoot RAW DNG pictures. Some apps already have burst shot in RAW mode. Im sending some e-mails to see if I can encourage the devs to introduce at least 1080p RAW video or a 30fps burst shot mode for a few seconds. Those phones are very powerfull and the hardware is far more advanced than most camcorders and DSLRs.. Im pretty sure its possible, but the problem is that the average smartphone user will never use that (video camera developers are giving up due to the lack of feedback). They are more interested on those nasty camera filters for instagram vaga 1 Quote Link to comment Share on other sites More sharing options...
vaga Posted August 27, 2015 Share Posted August 27, 2015 Not all 5.1.1 ROMs support Camera2 API, which I presume this app uses. Many of the features you mentioned likely require the ROM to have that API implemented. kaylee 1 Quote Link to comment Share on other sites More sharing options...

Cinegain Posted September 3, 2015 Share Posted September 3, 2015 Yeah, not too shabby, I like it.The only thing that kinda bugs me is the MF. It's pretty good within like a meter or 2 or so. But going a bit further away and between infinity and like 5 meters is like half a millimeter, so it's hard to nail. I need to explore it a little more.

dahlfors Posted September 3, 2015 Share Posted September 3, 2015 Thanks for the tip!Just tried it out on my 1080p-only Nexus 5. A major improvement over the default camera app! Quote Link to comment Share on other sites More sharing options...
