The larger the value the slower the gif will be but if the value is too high it will make impression of lags. delay sets the delay in time between gif frames in hundredths of a second, in our case it will be 0.03s. Level 3 will take more time to process but is the best optimization. optimize is used to shrink resulting gif. gif filter will transform video into a gif. f flag is used to set filter for ffmpeg, e.g. What happens under the hood is that if the original video has higher frame rate than 20 than ffmpeg will remove some frames and if it had lower frame rate it will duplicate some frames to obtain output video with desired number of frames per second. The shell command to optimize GIFs is: gifsicle -O3 animation.gif -o animation-optimized. r is a frame rate, in our case 20 frames per second. To put simply, pixel format is a kind of computer representation for color. These tools are available on most platforms. Extracting frames from animations is easy too: gifsicle anim.gif '0' > firstframe.gif. Making a GIF animation with gifsicle is easy: gifsicle -delay10 -loop. The first is: ffmpeg for cutting and manipulating videos, then Gifski for creating GIFs, and finally Gifsicle for optimizing and further manipulating your GIFs. Gifsicle is a command-line tool for creating, editing, and getting information about GIF images and animations. Each color channel (red, green, and blue) in video is allocated 8 bits per pixel. Step 1 Installing ffmpeg, Gifski, and Gifsicle In this tutorial, you will need three tools to follow along with the examples. rgb24 which is a format with 24 bits per pixel. 1400x800 means width of 1400 and height of 800 pixels. ![]() i flag prepends input file path (movie). The following are ffmpeg options which were used to create a gif:
