Another really promising snipet from NX1_packages\standard-arm7\usr\include\wideo\drime5\hdmi\d5_hdmi_video_type.h /** * @enum ColorSpace * @brief Color space of video stream. */ enum ColorSpace { HDMI_CS_RGB,/**< RGB color space */ HDMI_CS_YCBCR444,/**< YCbCr 4:4:4 color space */ HDMI_CS_YCBCR422/**< YCbCr 4:2:2 color space */ }; /** * @enum ColorDepth * @brief Color depth per pixel of video stream */ enum ColorDepth { HDMI_CD_36,/**< 36 bit color depth per pixel */ HDMI_CD_30,/**< 30 bit color depth per pixel */ HDMI_CD_24/**< 24 bit color depth per pixel */ }; I don't have an external recorder but doesn't the NX1 currently only offer 4:2:2 8 bit out?

I downloaded the source code a while ago and looked at it briefly but never found anything but after reading this tread I was inspired to take a second look and I found a whole folder of C++ files in the kernel package under driver\media\drime5\hevc. I even found this comment in one of them( d5_enc_host_ctrl.c). // Target cycle of 32x32 CU, P-slice // Mode1, LD_LC: 870 -- UHD30p @266MHz w/ 20% margin // Mode2, LD_HE: 1307 -- FHD60p @200MHz w/ 20% margin // Mode3, RA_LC: 1752 -- FHD60p @266MHz w/ 20% margin // Mode4, RA_HE: 2420 -- FHD30p @200MHz w/ 20% margin // Mode5, AI : 870 -- UHD30p @266MHz w/ 20% margin Does anyone here know anything about GNU licenses? My thinking is if they are using the drime5 CPU to code and decode HEVC it would need to be built into the Tizen kernel and would need to be open source. But I dont know for sure. I think its all there folks we just need a Linux/Tizen master to take a look at it.

The developer of RMMC is planning on releasing a new version of his much acclaimed H.265 converter tonight. This new version will now have the option for an input LUT. http://***URL removed***/forums/post/57045260 This will improve my workflow significantly. J I can't wait to try it out with the gammaDR2Log Lut

The case would fit a new PSU. Its the motherboard that has proprietary connectors that no other PSU has My power supply is rather for 320 watts and when I calculate my power usage with an online calculator it says my total load is 320 watts so it should just sqweek by. The second issue is I would need to get an adapter to use the SATA power cables to plug into the 8 pin power cable on the GTX 960. any one ever do this before?

I currently don't have an nvidia GPU, I have an AMD R7. In either case your point still holds up and I dont think upgrading my video card will help with playback of h.264 or h.265 files. Transcoding seams to be the only way to go as I can playback ProRes LT files smooth as eggnog (a little topical humor). However I do think the GPU will help with the dropped frames that I am seeing when I add effects to a clip. This lead me to do some more research and now I have a much worse problem that I don't think anyone here can help me with. A GTX 960 (or pretty much any video card worth getting for that matter) is going to require me to upgrade my power supply witch I was pretty sure was the case going into this but was ok with it because I would be able to reuse the PSU in a new computer in a few years. The problem is my computer is an HP and the PSU/motherboard has proprietary connectors :') I think I might be able to barely squeeze by with a GTX 960 if I get cable connectors to convert the two optical drive cables to an 8pin video card connector. What do you guys think lol It is also worth mentioning again that I got this computer for free about a year and a half ago and so I dont want no crap about buying an HP. lol

I actually have a WD red not green. I only really use it to store photos and video projects after I am done editing them. Thank you, Do you mind me asking what CPU you have?

No artifacts with ProRes yet (fingers crossed) I have always had my playback resolution set it 1/4 because my monitor is only 1080p and the playback window is only about 1/4 of the screen size. Is that not how it works? I will try 1/2 and full tonight and see if I can see a difference and see if it will still scrub. Yea I would really like to pick-up a new video cards to help with the effects playback but unfortunately the CAD is horrible right now so all the prices for me are ridiculous. >$300 for a GTX 960 Speaking of video cards how does the VRAM get used with editing? Should I opt for the 4GB version or is the 2GB alright?

Did some testing this weekend and solved the problem... sort of... So by transcoding to ProRes LT as suggested helped a lot. It will scrub a lot smoother even with 4K files. I also tried Cineform but did not see a noticeable difference from ProRes LT and since I am using RMMC for transcoding I will be using ProRes LT. Now the minute I add any effects or colour grade to the sequence the playback goes choppy again and won’t scrub smoothly. So I also ran a bunch of other tests to try and optimize my machine some more and figure that I wasn’t getting optimal performance out of my SSD so I optimized it by reducing the virtual memory window uses and enabling rapid mode. I also moved a bunch of junk off my SSD onto my HDD so that the percent free is a lot lower as I read this can speed things up as well. Conclusion I can now scrub smoothly as long as there is no video intensive effects on like warp stabilizer or colour grading. This will just emphases the importance of colour grading last. Thank you for everyone’s help.

Thank you again. I started to some research into codec and quickly got overwhelmed lol. Some time this weekend I will try to see if I see an improvement with cineform. I am also going to try Prores LT again. Your laptop, what CPU did it have and how does it compare to an i5-2500? This is where i feel like my computer should do better. If cineform doesn't help me out any other suggestions for optimization?

Thank you for the advice. Any recommended transcoder for H.265 to cineform? I currently use RMMC to convert to H.264. Also the option to add a LUT while transcoding would be useful as well. Also I was doing some research and it seems to me that I shouldn’t be seeing such poor performance with the i5-2500, are you sure getting a new graphics card won’t help?

I am not sure if I have a bottle neck. When I scrub through video is it definitely not smooth and take a second or two to catch up. When I monitor my CPU usage and GPU usage while scrubbing my CPU maxes out to 100% on all four cores but my GPU stays under 10% This makes me think that the GPU is not even being used and upgrading would relieve stress from the CPU. What do you think? Does adobe effectively use the CUDA cores for editing tasks like scrubbing and playback or does it only use them for rendering?

I can't speak to the A7SII specifically but what happens on the NX1 is in stills mode the aperture is always wide open until you take a photo or press the DOF preview then it stops down right before it takes the photo. Conversely, As soon as you put the NX in movie mode it will stop down the aperture and increase the ISO to preview the correct shutter speed. At least I think this is what it does. The NX1 also has a framing mode that does some funky things similar to this for framing in low light with flashes Does this sound like what is happening to you?

I currently have an old HP desktop computer that I got for free two years ago. It has the following specs; Core i5 2500 3.3 Ghz (quad core) 16GB of ram Gigabyte R7 240 OC video card SSD working drive and WD green storage drives My question is will I see an improvement in editing tasks(I dont care about rendering times) by upgrading my video card or is the computer just junk entirely? I was thinking about a GTX 960 for the H.265 support (I have an NX1). Also it might be worth mentioning that the motherboard only support PCIe 2.0. I know my computer is quite shitty but honestly I only edit videos that are 5 min long on a 1080p timelines.
