Description of alteration features For D5100 patch

Postby skiibojosh » Thu Mar 06, 2014 6:48 am

Here is a simple explanation of each portion of the Nikon D5100 Hacks. Hope this helps!
If you download any feature by accident, or try a feature and did not enjoy it, all you have to do is retry the patching process but leave the features you no longer want, un-ticked. When you install the newly patched firmware in your camera, it will essentially start the settings back to what they were before the hack, with any of the new features you did tick.

"Remove Time Based Video Restrictions"-
The D5100 naturally has a limit set on any videos you record. Either the video will be 20 minutes or it can be 4gb. Recording a video will stop regardless of which limit you hit first. The 20 min. time limit is seemingly due to taxes and the 4gb size limit is due to the physical limits of FAT files (i.e. the type of file the videos are recorded in). The "Remove Time Based Video Restrictions" hack allows the camera to bypass the 20 minute time limit. With this, you can record a video up to 4gb (which in high quality video is something close to 24 minutes as opposed to 20). You will still be limited by the 4gb size limit.

Liveview Manual Control ISO/Shutter
The D5100 does not allow for manual changes to ISO or shutter speed while in Liveview. When you set your ISO and shutter speed and then proceed to enter Liveview, the D5100 automatically adjusts ISO and shutter to achieve what the sensor believes is the proper exposure. The ISO and shutter speed seem to remain the same setting (numerically on the scree), but the user actually has no control. The user can even change the numerical ISO and shutter speed settings in Liveview, but the camera does not actually respond. This hack allows the user full manual control over ISO and shutter speed in Liveview.

Clean HDMI & LCD Liveview
The D5100 Liveview screen contains a myriad of settings and icons to provide you different detailed information about what you are seeing/recording. The most minimalistic setting for Liveview still includes :the mode type, battery, shutter speed, aperture, iso, and remaining card size. The D5100 has an hdmi port on the side which allows someone to record to an external recorder or display live what is happening on the camera. All of the Liveview information on the Liveview screen will also be part of the HDMI feed out. The "Clean HDMI & LCD Liveview" removes all icons from the Liveview screen which will also remove it from any HDMI feed out. Currently, the hack is not configurable to allow you to switch between icons and clean. If you install this hack it will be a completely clean Liveview.

Video 1080 HQ - 36 mbps Bit - Rate
The D5100 naturally compresses video files to allow for longer video files. In the process, it loses some quality. Naturally the D5100 records video at 18 mbps with the High Quality setting selected. With the hack, the camera will record 36 mbps with the High Quality setting selected (the hack replaces the 18 mbps setting with 36 mbps). The increase in quality is noticeable with fine details or rapid movement. This will reduce recording time due to the 4gb limitation of the FAT file format used to record the video. Due to the increased file size: depending on the speed of your SD card, the file may not playback in camera.

Video 1080 HQ - 54 mbps Bit - Rate
The D5100 naturally compresses video files to allow for longer video files. In the process, it loses some quality. Naturally the D5100 records video at 18 mbps with the High Quality setting selected. With the hack, the camera will record 54 mbps with the High Quality setting selected (the hack replaces the 18 mbps setting with 54 mbps). The increase in quality is noticeable with fine details or rapid movement. This will reduce recording time due to the 4gb limitation of the FAT file format used to record the video. Due to the increased file size: depending on the speed of your SD card, the file may not playback in camera.

NEF Compression OFF
The D5100 takes RAW pictures in the NEF format. Even these RAW files, however, are compressed. This hack will turn off the any compression that goes into making the RAW image. Therefore, the pictures' will have more detail. The tradeoff is that with "NEF Compression Off" the file sizes are larger than they are with compression. This cannot be ticked with "NEF Compression Lossless" because by their very nature they are mutually exclusive.

NEF Compression Lossless
The D5100 takes RAW pictures in the NEF format. Even these RAW files, however, are compressed. This hack will change the file type to a lossless file type. In simple terms, it will compress it (which means smaller file sizes) without losing information. The general consensus among most tests suggests that Uncompressed (NEF Compression Off) does not have a noticeable amount of difference compared to Lossless (NEF Compression Lossless). NEF Compression Lossless is in that way subjectively better. This cannot be ticked with "NEF Compression Off" because by their very nature they are mutually exclusive.

Nikon Star Eater
This hack is for astrophotography. The D5100 (and many other cameras) process the RAW files in camera. Sometimes, when shooting in complete darkness, a small electrical charge will light up a pixel even when there was no light in the shot creating a colored dot in the picture. These dots are called hot pixels. When shooting in extremely dark light with shutter speeds slower than 1/4, a filter (called Hot Pixel Suppression) gets applied to the shot to prevent the sensor from making these. The tradeoff is that when shooting astrophotography, the sensor may think that small bright stars are hot pixels and may remove them from the camera. This hack removes the HPS filter allowing stars to be naturally shown.

JPEG Compression - Quality (Vs. Space)
The D5100 provides the option to take pictures in JPEG. The JPEG compression algorithms make compromises to tradeoff quality for the data size of the picture and vice versa. The D5100 naturally chooses to compress JPEG to have smaller file sizes, thus losing some quality to the picture. This hack will tell the camera to prefer better quality JPEG's creating larger file sizes.

Non Brand Battery
The D5100 firmware almost exclusively only works with Nikon's own branded batteries, rendering third party batteries useless or less than ideal. This hack allows third party batteries to be used in the camera and to also display their battery life correctly.
