Performance Mode A lot of players like me prefer to run fortnite with “Performance Mode” (Low Graphical Fidelity) rendering mode because it generates very clean and minimal graphics giving a competitive edge in the game by making opponents more visible and easy to target. The upside is that disables lots of graphics features like antialiasing,… Read More »
HLG (Hybrid Log Gamma) is a gamma curve (scheme) for encoding videos in hdr format developed by BBC and Japan’s NHK for broadcasting. It provides wider dynamic range compared to the standard picture profile in sony camera. Moreover HLG format is backwards compatible with non-hdr display sets that support only sdr. If you have a… Read More »
In earlier days we used to have commands like kdesudo, kdesu, gksu that would easily allow us to run applications with root privileges. But these commands have been discontinued and totally removed from modern versions of ubuntu and debian many other distros. It is believed that running a gui application as root poses security threats…. Read More »
Preview lag or choppy playback is a common thing in shotcut that a lot of users complain about.

As soon as we turn on our systems, it’s very crucial for us to understand the processes that get triggered. Hence, it is really important for anyone to go through the concepts of booting to understand how an operating system behaves and also to resolve any booting error. Since we’re talking about Linux systems here,… Read More »
Some time ago I had purchased a Seagate One Touch 5TB hard disk, and used it mostly for redundant backups and virtual machines. Suddenly a week ago I noticed that it has stopped working and plugging it into the usb port brought up nothing in the file manager. I tried plugging it into different usb… Read More »
FFmpeg can work with a lot of different codecs for both encoding and decoding video files. It is used as a backend by video editors like Shotcut and media processing library frameworks like MLT Multimedia Framework. In this post we shall take a look at some of the most commonly used video codecs, their features… Read More »
HDR vs SDR HDR (High Dynamic Range) is the newer and more advanced version of display technology that shows more colorful and brighter pictures on displays that support it. It is much superior to its predecessor SDR. Videos in HDR format use 10-bits for storing color information and use different color transfer functions compared to… Read More »
Ram Timings are an important part of the ram specifications. They look like a series of number like this: 22-22-22-52. These timing numbers indicate how fast or slow the ram would perform in conjunction with the cpu. Higher timings indicate that the ram takes more time to internal operations, and is slower. Lower timings mean… Read More »
RAM Speed (read and write) is crucial to the overall performance of the system. Having a fast cpu but slow ram can slow down a system in demanding work-loads like video editing and gaming. Ram size and speed are different factors. Ram size determines how much data can be stored in the system, whereas the… Read More »
