![]() ![]() Really! 42ms is equivalent to 24fps, while 100ms is equivalent to 10fps. I'm personally a fan of 100ms, but 42ms is another popular option. so a good frame count is what?Īctually, we want to choose the frame delay first. So, if you selected a five second portion of a video, you'll create a five second GIF. So, how do I choose a good frame count and delay?īefore choosing, I'll make the assumption that you want the duration of your GIF to equal the duration of your clip. Frame Delay The length of time that each of the frames will be displayed in the GIF. What are the frame count and frame delay settings? Frame Count The number of frames between the start and end times that GIF Brewery will extract from your video. Coming soon, we'll also be adding other interesting optimization techniques: optimizing by reducing the color palette to fewer colors (for example, from 256 colors to 32), optimizing via dithering, optimizing by the GIF disposal method, optimizing by creating partial frames with modified x, y, width, height arguments, optimizing by dropping repeated frames, optimizing by using a lossy GIF compression algorithm, and optimizing by dropping local color tables and using only the global color table.A very important aspect of GIF creation with GIF Brewery is perfecting your frame count / delay choice. The size of the new GIF file can be seen in the options by clicking the "save as" and "download" buttons. Our program lets you immediately see the result of transparency and frame skip optimization methods in the browser's GIF preview windows. You can use one of the methods or multiple methods at once. You can enable or disable each of the optimization methods in the options. If you skip every second frame, the GIF file size can be reduced by 40%. This optimization method is very effective. When skipping frames, the duration of the GIF does not change because the optimizer increases frame delays of the remaining frames to preserve the original GIF duration. For example, "1, 3, 6", which means skip frames one, three, and six, or "2-10", which means skip all frames from the second to the tenth. You can also delete specific frames that you enter. You can skip every 2nd, 3rd, 4th, or nth frame starting from any frame. The skip-frame optimization changes the number of frames in a GIF. This method is less efficient than transparency optimization but a value of 10 - 30 pixels creates visible a result. A larger sampling radius introduces tiny errors in the quantizer that leads to better optimization. The quantizer optimization changes the pixel sampling radius of the quantizer. Usually, it is sufficient to enter a small similarity threshold value of 1% - 5% to obtain good optimization results. Pixel similarity is defined via the threshold option. If the pixels in the next frame are the same (or very similar) to the pixels in the current frame, then they are made transparent in the next frame and as a result, they are skipped. ![]() The transparency optimization compares pixels frame by frame. ![]() There are several optimization techniques that we have implemented: transparency optimization, quantizer optimization, and frame-drop optimization. Optimizing a GIF has many benefits – it uses less computer memory and loads much faster in the browser because there is less data to decode. This is a browser-based program that optimizes GIF animations. ![]()
