- Do I have to Pay?
- No the patch is free, contributions are welcome if you find the changes useful.
- I have paid my money, I want X
To test the hack, I took a Nikon D5000 and a Lytro out for an afternoon by the water, setting each camera up on a tripod and framing the same shot so that the two could be compared. Photography videos are an interactive way to learn new techniques. Browse Nikon's photography tutorials and other videos to help fuel your talent. The camera was locked down on a tripod and used the Neutral Picture Profile. I selected a sunlit scene of a running stream of water with highlights on the water ripples. This type of subject presents a myriad of high-contrast moving images that tax the motion tracking and bitrate allocation algorithms of the camera's H.264 video encoder. If you’re going to be doing a lot of video with your new camera, this will prove to be a major annoyance. Not to mention there are many more resources out there for Canon DSLR video – believe me, I’ve looked. The Bottom Line. Nikon makes great cameras, has a huge, supportive community, and there really isn’t a wrong choice. Connect your Nikon camera to your computer using the USB cable that was included with your camera. If you’re using an external mic such as the Nikon ME-1, etc., plug it into the computer’s mic port. Open any one of the compatible video conferencing software (Zoom, Microsoft Teams, Google Meet, Facebook Messenger and Skype).
- Ah, I’m sorry you have not purchased anything, We will refund your money. we will try help you getting it working, and if you like what the results, you are welcome to contribute.
- It does not work
- Have you followed the steps in the Help Page and checked if your screen looks like the What Should I See diagram? We have reports that the Silverlight application is blocked on some work networks, does it also not work from home?
- Can I revert to Original Nikon Firmware
- Yes, just like a normal Nikon update. To date Nikon has done nothing to stop you changing to any old/new firmware for any model DSLR camera (as long as it’s done correctly) so you will have no issues.
- Will this damage my Camera
- The patches/changes on the Release Patch Tool, have been tested on other peoples gear, and we have had not issues reported, so you should be OK, the patch might not work, but your camera should be able re-flash the Nikon original firmware. The BETA patch more risky, anything labeled ALPHA you should consider as ‘has never ran on hardware’ and your camera might not survive.
- Are any patches dangerous?
- Yes – The non-brand battery patch, allows you to use batteries that are from third parties, these may not be safe from a fire hazard perspective. Also the patch tells the camera the battery is ‘all good’ which 100% safe except when flashing new firmware, as the battery charge level is fiddled with, if the battery run low the camera will turn off mid flash, and your camera will be ruined. So never flash firmware with third party batteries and always use genuine Nikon batteries that are fully charged. For the same reason never use the external power supply while re-flashing, as that power source can also be interrupted, with the same bad results.
- I have a Mac OS X system
- Microsoft have a Silverlight plugin for the Mac, it works.
- I have a Linux system
- I understood Moonlight works, but I also hear this is a pain to install. Do you have any friends with a Mac or Windows system. I know, weak answer.
- I still haves issues, Help
- Sure, come to the NikonHacker.com Firmware Forums and ask your questions there.
- What does the contributions get spent on?
- To date:
- $400USD to replace Simeon’s D5100 after bricking it testing Alpha changes, see it happens. The original camera is being used to learn how to recover dead gear, but presently is still dead.
- $165USD to replace 4cc3ss's D3100 after bricking it testing Alpha changes.
- $590USD IDA license
- $40 RawDigger license
- Why is the D5100 get changes and model X is ignored?
- This is hard work trying to understand how the code works, we have made the most progress on the D5100, so we mostly stay on the model as that's were the knowledge is.
- Why the feature I want is not available at the latest firmware version?
- Every time Nikon compiles the new version of source code, the compiler may reorganize the binary structure depending on increased code base or data structure. Thus the same patch for version A may not be in the same location for version B. Reanalyzing takes time. If you want it, you might be the one to start looking at the latest firmware!

- When will new Model X be supported
- Until a firmware update is released by Nikon, there is not much we can do.
- Yes we can dump the memory from some camera models, but it's so much safer to base work off an full release. Also using a dumped release would be Copyright infringing, so really not going to happen outside core team.
- I want feature X but you guys keep working on Y
- We are doing the work, so what interests us is what we do
- See Why is this taking so long
- We are working on things that are based on what we have discovered/learnt
- It's not easy to inject new code, so it's not just a matter of wanting.
- Why is this taking so long
- We work on this in our spare time
- Simeon for example also like to take pictures and play Xbox and spend time with his family (as do the rest of the team)
- The processors are not standard x86/ARM processors
- There is more than one processor, of different types
- We are working by trying to understanding the assembly code, based from working from known edge pieces (jigsaw puzzle reference) like USB, File operations, Menu text, or HDMI protocol
- This is like trying to understand how a master photographer takes pictures by only looking at the foot prints the make in the sand.
- Why is the D3100 Movie time restriction 17:28 instead of more?
- The D3100 had a 10 minute limit, and the counter for this limit fits inside a 16-bit number, where-as the other models with their 20 minute limit require a 32-bit number. Due to this ~18 minutes is the largest time that the movie engine can handle, but the assembly code that set this limit does it using a method that allow set the exact max thus 17:28 is the largest value that can be loaded in, without too much changes. So the effort to increase the time counter form 16bits to 32bits is more than the collective interest the current developers, so has not happened.

D5100 macroblock artifact comparison:stock 24Mbps versus hacked 54Mbps
How To Use Nikon Camera
I recently shot comparison tests of the D5100 in 1080p24 and 1080p30 video modes, using the stock 24Mbps bitrate, and hacked 36Mbps and 54Mbps bitrates. I took these shots with a Tamron 24-70mm f2.8 lens set at 70mm, f5.6, and ISO 100. The camera was locked down on a tripod and used the Neutral Picture Profile. I selected a sunlit scene of a running stream of water with highlights on the water ripples. This type of subject presents a myriad of high-contrast moving images that tax the motion tracking and bitrate allocation algorithms of the camera's H.264 video encoder.
In 1080p24 mode, the D5100 records in H.264 IPB format using 12-frame GOP. In 1080p30 mode, the D5100 records in an IP format using a 15-frame GOP. After loading the video files into a 32-bit Adobe After Effects project, I selected I, P, and B-frames from the second GOP in each video sample. I then displayed and cropped them at 200% magnification in side-by-side 24Mbps versus 54Mpbs comparison shots, and saved screenshots of each comparison.
I-frame Comparison @ 1080p24 (IPB 12-frame GOP):
P-frame Comparison @ 1080p24 (IBP 12-frame GOP):
B-frame Comparison @ 1080p24 (IBP 12-frame GOP):
I-frame Comparison @ 1080p30 (IP 15-frame GOP):
P-frame Comparison @ 1080p30 (IP 15-frame GOP):
H.264 encoders divide each video frame into horizontal and vertical rows of tiles called macroblocks. Sophisticated compression techniques are used to compress the encoded data within each macroblock, reusing image data from adjacent macroblocks and video frames. After the H.264 decoder reconstructs the encoded pixel data, it uses a built-in Deblocking Filter to blend the rectangular edges of the adjacent macroblocks together. With extremely detailed moving images, however, the encoder's image quality may deteriorate when it reaches the limits of its maximum bitrate. This can produce not only smeared image details, but undesireable macroblock artifacts as well, which can be seen in the sporadic rectangular edges in detailed areas of the decoded frame grabs.

Consumer-grade H.264 encoders are optimized to maximize data compression rather than image quality. They will typically encode highly compressed B-frames at lower image quality than the I and P-frames. This can be seen in the noticeably coarser macroblock artifacts in the 24p B-frame image recorded at the stock 24Mbps bitrate. However, the I and P-frames of both 24p and 30p videos are also contaminated with noticeable macroblock artifacts.
Frame grabs from the 54Mbps 24p and 30p videos show significantly fewer macroblock artifacts and finer image details than the 24Mbps videos. While the macroblock edges in the 54Mbps frames are fairly well blended, more seamless results could potentially be produced by hacking the encoder's Deblocking Filter coefficients. A more effective Deblocking Filter might also make it possible to achieve comparable image quality at bitrates lower than 54Mbps.
