If there is some software that adds a watermark to video, then there must be some other program that removes the watermark from video. Watermarking a video is very simple and fast, because its actual operation is just to add watermark to each frame in batch. However, removing the watermark in a video is just like removing the watermark from an image - there are two problems: 1) more complex image processing techniques are required (mainly to calculate and refer to the color distribution around the selected area); 2) it's unable to remove the watermark perfectly, there will always be some flaws.

As we all know, the greatest benefits of the image file format are security, stability, and high compression. Therefore, many collectable files are made into ISO or other image file formats for preservation and distribution. Instead of burning an image file as a CD/DVD as before in order to view the files inside, you can always use a file archiver like 7-Zip to direct extract them out (which can be time-consuming), but a better way to do that is use a virtual drive.

When we are playing some 3D games, the game may encounter problems such as picture jam, or even crash because the performance of our computer hardware cannot keep up with the demands of game. Of course, there are a lot of graphics card optimization software, such as Rivatuner, Nvmax, Rage3D, etc., but most of them cannot optimize all the graphics adapters in the market. More importantly, the traditional optimizer perform optimizations based on the architecture of graphics card itself, which at best makes the graphics card better play its own performance.

Chankast is an advanced and free SEGA's Dreamcast system emulator for Windows x86 platforms, developed by garrofi, baktery, una-i and ElSemi in 2004, released as a tribute project to the great DC console, other than a promotion to piracy. It is one of the first Dreamcast emulators to run games in a playable way, also the first Dreamcast emulator to be able to run commercial games.

Recently, my camera broke down and I had to use my laptop's low-end inbuilt camera to take photos (I haven't had a smartphone yet, maybe I will buy one as soon as possible for the convenience of taking photos). Even worse, the image format used by ECap is BMP, which is extremely big in size. So I tried to convert it to PNG format with PNGGauntlet, but found that it would take dozens of hours at least to convert 356 BMP format of images to PNG format. This is really a bit joke!
